Title: Manufacture of vertical field effect transistor
Inventor: YANAGAWA HIROSHI
IPC: H01L21/336
Filed: 1991-06-19
Abstract: PURPOSE:To enable a channel to be lessened in dispersion of length by a method wherein impurity contained in a base region is set larger than that contained in a source region in diffusion coefficient, and impurities used for forming the base and the source region are injected to form diffusion layers at different levels using a gate electrode as a mask. CONSTITUTION:P-type impurities such as boron 4 are implanted through the intermediary of an oxide film using a polysilicon gate electrode 4 as a mask, and N-type impurities such as arsenic 7 much smaller than the P-type impurities 6 in diffusion coefficient are implanted through the intermediary of a resist 8 and the polysilicon gate electrode 4. Thereafter, a base region 9 of a P-type diffusion layer and a source region 10 of an N-type diffusion located at a shallower level than the base region 9 are formed through a thermal treatment of high temperature. By this setup, both P-type impurities and N-type impurities can be ion-implanted from the same polysilicon position and a channel length L can be set constant.

Title: Groove copying method
Inventor: SHIINA IKUO
IPC: B23K9/02
Filed: 1982-08-24
Abstract: PURPOSE:To perform welding along a groove without using the sensor to be used exclusively for tracing the groove, by controlling the direction of oscillation so as to copy the groove in accordance with the command for moving upward a welding torch upon arriving of the arc at the groove end when the welding torch is oscillated while an arc voltage controlling system is operated. CONSTITUTION:When a welding torch 12 moves in an arrow A direction and an arc arrives at a groove wall 14, the arc length l shortens. Therefore the detected arc voltage attains the value lower than a set value 1 and a command for moving upward the torch is transmitted from a comparator 3. A set commander 6 detects the rise of the command for moving upward the torch and sets an integration circuit 8 thereby starting an integration action. When the integrated value attains the value set in a commander 9 for selecting oscillation directions, the command for selecting the oscillation direction is transmitted from the commander 9. Then an oscillation circuit 10 runs reverse the rotating direction of an oscillation motor 11, thereby reversing the oscillation direction of the torch 12. Since the command for directing downward the torch is transmitted from the comparator 3, a commander 7 for resetting detects the command for moving downward the torch and resets the circuit 8.

Abstract: PURPOSE:To enable smooth segregation of printing paper from a plate cylinder using a simple device by providing an air suction hole for a stencil paper on the external periphery of the plate cylinder, on a segregation claw for printing paper installed at the paper discharge side of the plate cylinder. CONSTITUTION:The air supplied from the axial core 15b of a segregation claw 15 is aspirated in 'A' direction from an air aspiration orifice 15a. That is, ink from an ink roller 14 is transferred to printing paper 12 supplied from a paper feed table by a press roller 13 after passing through the stencil paper 21 on the external periphery of the stencil paper 7. After this, the printing paper 12 passes through the part where the pressure of the press roller 13 is applied, and then is segregated from the plate cylinder 7 around which the stencil paper 21 is wound by the firmness of the paper 12 itself. In this case, air is aspirated to the segregated part from the air aspiration orifice 15a of the claw 15. Consequently, the segregation effect becomes significant and therefore, the ink on the paper 12 becomes dry. This drying process further improves the segregation effect.

Title: Multilayered ceramic substrate
Inventor: KIYOSADA KAN
IPC: H05K3/46
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a multilayered ceramic substrate which can be positioned accurately, even when a laminate deviation occurs between upper and lower ceramic layers and in which no crack occurs, even when a load caused by stresses due to the difference between the coefficients of thermal expansion of the substrate and a jig, an external force, etc., is impressed upon the substrate via a positioning pin. SOLUTION: A multilayered ceramic substrate 1 is constituted by laminating a plurality of ceramic layers 1a, 1b, and 1c upon another and forming positioning notches 3 which penetrate the ceramic layers 1a, 1b, and 1c on the outer peripheral edge of the ceramic layers. Each notch 3 has a narrower width W1 and a deeper depth D1 in one of the ceramic layers 1a, 1b, and 1c. Therefore, even when a laminate deviation occurs among the ceramic layers 1a, 1b, and 1c, the substrate 1 can be positioned with high accuracy, because the upwardly and downwardly projected widths of the notches 3 are always fixed. In addition, crackings of the substrate 1 can be prevented effectively, because stresses which are generated in the interior sections of the notches 3 can be scattered satisfactorily to the ceramic layers 1a, 1b, and 1c.

Abstract: PURPOSE: To easily obtain a gasified fuel and attain a complete combustion with a gasification block provided in a gasification chamber in which a fuel oil is gasified, and with hot air produced in a combustion chamber and introduced into the gasification chamber.  
     CONSTITUTION: When kerosene is supplied from a kerosene tank 9 into a gasification chamber 3, it is sucked into a porous gasification block 7. When air is then introduced into this combustion device through a pipe 21, it flows through a heat exchanger 19 and a hot air supply pipe 8 into the gasification chamber 3. The air then flows through horizontal bores 7b and vertical bores 7a in the gasification block 7 to come into contact with the kerosene, which is thereby gasified. The gasified fuel, which has a predetermined air/fuel ratio, is turned via a partition plate 12 and a mixer 13. The gasified fuel is then ignited at openings 15 in a combustion chamber 5 so as to be burnt. A combustion waste gas is discharged to the atmosphere after it has been used to heat in a heat exchange chamber 6 the air flowing from the pipe 21 to be passed through a heat exchanger 19.

IPC: G03F1/00
Filed: 1979-11-14
Abstract: PURPOSE:To prevent trouble due to fixing a protective cover, by providing the cover located apart from a photomask pattern for use in pattern formation of integrated circuits at an interval larger than the focal depth of the optical system of an exposing device for exposing the pattern. CONSTITUTION:Protective glass cover 4 having in the middle part a recess larger than the pattern forming region of mask pattern forming face 2 of photomask glass substrate 1 is stuck to substrate 1 on sticking face 5. When ultraviolet rays fall on mask 8 from light source 6 through condenser lens 7 and further fall on the body 10 to be processed through contracting lens 9, and the distance between the inner face of cover 4 and pattern face 2 is, for example, several times as much as the focal depth of lens 9, even if a scratch is made on the surface of cover 4, its image is made vague and is not formed on the face of body 10, thus permitting bubbles occurring in the adhesive layer caused by sticking the whole surface of cover 4, and trouble due to aging change of the adhesive layer to be prevented.

Title: Interpolation circuit for step waveform
Inventor: NAKAMURA KAZUTO
IPC: H03K6/00
Filed: 1987-06-12
Abstract: PURPOSE:To output an analog signal without causing a quantization error by converting a counter output into the analog signal, converting a time series pulse signal into a voltage in response to the frequency, integrating its F/V conversion output and adding the integration output and the analog conversion output. CONSTITUTION:The input pulse signal is counted as it is by a counter 5 and its output is D/A-converted. On the other hand, an F/V converter 7 converting an input clock pulse into a voltage corresponding to the pulse number is used, the output is used as the input to operate integration devices 10, 11 respectively at the interval of the pulse width to obtain a sawtooth waveform integration output, and the integration output is added to the D/A conversion output. Thus, even when the input signal is a clock pulse signal corresponding to the number of revolutions such as a rotary encoder 1 or a signal read out of a ROM storing the waveform data, the D/A conversion output is interpolated linearly as the output. Thus, the analog signal without quantized error is outputted.

Title: Power transmission gear for fan
Inventor: SHITOU NAOMICHI
IPC: F04D25/02
Filed: 1979-11-16
Abstract: PURPOSE: To obtain the determined range of speed change in such a way as making the general air conditioning fan for a cooling tower or the like remarkably compact and light in weight by integrating an accelerating/decelerating belt speed change gear at the first stage and a belt decelerator at the next stage.  
     CONSTITUTION: Power introduced by an input shaft 1 is transmitted through a belt 4 to an intermediate rotary shaft 2, makes speed change at the first stage, namely at the initial stage, whereat both deceleration and acceleration are done, and further deceleration at the next stage is done by transmitting the power from the intermediate rotary shaft 2 through a belt 5 to the output side 3. Thus, a variable diametral nonstage speed change gear which operates the initial stage transmission both as an accelerator and as a decelerator in a dual stage belt transmission gear is also made compact to be able to hold a fixed speed ratio belt reduction gear into one housing for the next stage transmission. This allows for securing the determined  range of speed change without imposing a big burden to the belt at the next stage.

Title: Motor-driven mold clamping device
Inventor: ADACHI NOKIYOSHI
IPC: B29C45/66
Filed: 1986-06-24
Abstract: PURPOSE:To speed up opening and closing of a mold and realize a strong mold closing by a motor with a small capacity by a structure wherein two screw mechanisms, the twisting directions of the screws of which are the same with each other and at the same time the leads of the screws of which are differnt from each other, are employed in combination. CONSTITUTION:When a housing 6 is fixed to a rotating member 9 by engaging clutch mechanism 16 and 16' with each other simultaneously with the rotation of a motor 21, the housing 6 rotates together with a shaft 12 so as to actuate screw mechanisms 4 and 13 (in this case, screw mechanisms 8 and 14 do not work). By the action of the screw mechanisms 4 and 13, which have large lead of screw, a movable plate 1 moves at a high speed in the direction of closing (a closing process). At the final stage of closing, the contact of the molds is detected by detecting means installed on a fixed plate and on a movable plate 1. A detection signal of the detecting means disengage the clutch mechanisms 16 and 16' and engages clutch mechanisms 20 and 20' so as to fix the housing 6 to a support backing plate 5. As a result, the movable plate 1 moves in the direction of closing at a low speed, which corresponds to the difference between the leads of screws 13 and 14, so as to close the molds by a large force (a closing precess).
