Title: Controller for motor
Inventor: TADAKUMA SUSUMU
IPC: H02P7/293
Filed: 1985-08-23
Abstract: PURPOSE:To improve response to a speed command by introducing a virtual speed control system and dividing a speed control system. CONSTITUTION:A closed loop constituted by backward connecting a control block 10 for a reference model to a speed control amplifier 10 consisting of a PI element prepares a current command i*s on the basis of an angular velocity command Wr*. The current command i*s is converted into a current command i*s1 by a block 12, and transmitted over a control block 13 (a transfer function section for a motor-current control system and a mechanical system). Gains GB are selected so that the response of actual angular velocity Wr to the current command can be made to approximate by a time constant TM. Gains GF are determined so that GF/GB is equalized to the stationary gains KM of the reference model. Accordingly, the response to the change of a command value can be improved.

Title: Evaporator
Inventor: HIRAO YASUHIKO
IPC: F25B39/02
Filed: 1992-07-13
Abstract: PURPOSE:To improve vaporizing performance by a method wherein a heating medium inlet piping forms a straight pipe, the length thereof is set to a value lower than the specified multiple of the bore of the outlet of an expansion valve and by forming an uneven surface in the inner surface of the heating medium inlet piping, a vapor-liquid phase is kept in a uniform state when a heating medium flows through the interior. CONSTITUTION:A heating medium of a vapor-liquid phase flow flowing through an outlet 1a of an expansion valve 1 flows through a heating medium inlet piping 3A, which is a straight pipe having the inner surface being uneven surface and has length 20 times or less as long as the bore of the expansion valve 1, to a heat exchanger inlet header 4. The heating medium of a vapor-liquid phase flow flowing in the heat exchanger inlet header 4 is equally distributed to a plurality of heat transfer pipes 7. Heat is imparted thereon from heating fluid 8 to vaporize the heating medium, which flows to a heat exchanger outlet header 9 and flows out through a heating medium outlet piping. By forming an uneven surface 5 in the inner surface of a heating medium inlet piping 3A, a liquid film 5 flowing on the inner wall of a pipe is apt to be scafferd. Mixture and uniformization of a vapor-liquid phase are further promoted, a heating medium of a vapor-liquid phase flow in the inlet header 4 of the heat exchanger is equalized in quality, distribution of a flow rate to a plurality of the heat transfer pipes 7 is further equalized, and vaporizing performance and heat transfer performance are improve.

Title: Manufacture of semiconductor device
Inventor: MIZUNO TETSUYA
IPC: H01L29/74
Filed: 1986-08-07
Abstract: PURPOSE:To prevent surface layers from being shortcircuited even if a recessed part is formed due to pinholes to reduce malfunctions thereby to obtain an inexpensive semiconductor device by forming by selective diffusion the surface layers locally and deeper than the height of a step, and then digging an adjacent layer interposed between the surface layer regions by a step amount to expose the sides of the regions. CONSTITUTION:An nE layer is formed not on the whole surface of a semiconductor substrate 1 formed with PNP a layer but by selective diffusion at a position of a cathode electrode. Then, it is covered locally with a mask material 8, and the step of digging a gate is executed. Thus, a recess 9 is exposed at the side of the nE layer by removing a part interposed between the nE of a pB layer. When pin holes exist on the material 8, even if a mixed acid is impregnated downward from the pinholes to open a recess 7 in the substrate 1 disposed thereunder, it is not etched deeper than the recess 9 to become a gate. Accordingly, it does not arrive at the pB layer. Therefore, even if an electrode material is introduced to the recess 7 when a cathode electrode 5 is formed thereafter, the nE layer and the pB layer are not shortcircuited.

Title: Optical unit and vertically downward illuminator
Inventor: RI MASA
IPC: G02B21/16
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To enable adaption to light having a wide wavelength range, to maintain an accurate image position, and to make an optical system compact by composing the optical unit and a vertically downward illuminator of a specific mirror element and a specific image forming lens. SOLUTION: When the projection light from an illumination light source 5 is made incident from one opening of the through hole 1b of a unit main body 1, light of, for example, >=400nm in wavelength is reflected by the surface of the mirror element 2 and projected from the other opening of the through hole of the main body 1 to irradiate a dyed sample 7 through an objective 6. Fluorescent light in the visible wavelength range which is excited on the sample 7 travels through a reverse optical path to enter the other opening of the through hole of the main body 1, and is transmitted through the element 2 and made incident on the image forming lens 3 incorporated in one opening part of the through hole to form an image of the sample 7 at an image formation position.  In this case, the maximum remaining chromatic aberration of visible light wavelength that the lens 3 corresponding to the light in the visible wavelength range is about 0.13mm and becomes small as compared with the focal length of the lens 3, so that the image which is in focus can be formed.

Title: Tension control device
Inventor: FUJIWARA YUJI
IPC: B65H23/182
Filed: 1988-07-27
Abstract: PURPOSE:To enable a stable control to be performed of tension from a winding start to a winding end by connecting a unwinding roll shaft to a drive source through a contactless electromagnetic clutch and a contactless electric brake, in the case of a tension control device in winding of an electric wire or the like. CONSTITUTION:In a condition that a rewound object 4 is fixed in its end part to a rewinding roll 1 with a contactless electromagnetic clutch 11 connected, when a drive source 14 is driven, an unwinding roll 2 is rotated in a direction of unwinding the rewound object 4 through the clutch 11 and an unwinding roll shaft 3. Thus applying tension to the rewound object 4, when the tension exceeds a predetermined value, the clutch 11 slips. Next a contactless electromag netic brake 13 is energized stopping rotation of the shaft 12, and the drive source 14 is stopped, while the roll 2 stops its rotation, maintaining the tension of the rewound object 4. From this condition, when the roll 1 is rotated in the rewinding direction, a stable control of required tension can be performed from a winding start to a winding end.

Title: Semiconductor memory
Inventor: EDO YASUHIRO
IPC: G11C11/407
Filed: 1991-06-28
Abstract: PURPOSE:To prevent the writing and reading malfunctions of a semiconductor storage by driving a word line and raising the voltage up to a level higher than the power voltage when the word line is reduced down to a prescribed level. CONSTITUTION:An RA circuit 31 generates the reference level voltage of a word line, and an RAI circuit 33 selects a cell plate 37 and an X decoder circuit 35. The circuit 35 selects a word line. The voltage of a level equal to the level of the word line generated by the circuit 31 leaks out to a digit line of the plate 37 or another adjacent word line and drops. Thus the contact potential of an RA level detecting circuit 39 also drops. When the potential drops down to a prescribed level, this drop is detected by the circuit 39 and the dropped voltage of the word line is raised again up to a level higher than the power voltage by an inverter of the next stage. Thus the voltage leaks out to the digit line or the adjacent word line or the voltage is leaked out of a boot-up circuit. Thus the level of the word line is reduced. However the writing and reading levels are much assured and the writing and reading malfunctions can be prevented.

IPC: H04N7/15
Filed: 1983-10-06
Abstract: PURPOSE:To eliminate the feeling of dissidence of conversation due to the dissidence of a picture and voice by controlling a system that a voice delay circuit is inserted at the transmission of a portrate in transmitting a television picture on a satellite line and a voice signal on a ground line. CONSTITUTION:For example, a TV camera 11a photographs the entire scene of a conference room and a TV camera 11b photographs the portrates of the conference participants. When the camera 11b is selected by an image pickup picture designating signal I and a closeup image of a speaker is transmitted, the system is controlled that the voice delay circuit of a voice signal transmitter 15 is operated by the output signal of an image pickup pattern controller 17. Since the circuit is controlled that the amount of delay of the voice delay circuit is identical to the delay time of the satellite line, the movement of the mouth of the speaker and the voice are coincident at the conference room at the reception side thereby giving no feeling of disorder.

Title: Tuning circuit of radio receiver
Inventor: HAGITANI SHINICHI
IPC: H03G5/24
Filed: 1982-10-25
Abstract: PURPOSE:To improve the Q factor of selectivity characteristics and increase reception precision during channel selection, and to lower the Q factor and obtain high fidelity after the channel selection, by controlling a switching means provided to a tuning circuit by a muting control signal. CONSTITUTION:The output of the inverting circuit 12 of a muting driving circuit 19 is at a high level in the channel selection, i.e. when a synthesizer part is in an asynchronous state. Its signal is applied to the base of a transistor (TR) 23, which is turned off to prevent the influence of a resistance 50 upon the operation of the tuning circuit 16a. Namely, the Q factor of the tuning circuit 16a is decreased in the asynchronous state. When the synthesizer part is placed in a synchronous state after the channel selection is completed, the output of the inverting circuit of the driving circuit 19 falls to a level ''0'', so the TR23 turns on to exert the influence of the resistance upon the operation of the tuning circuit 16a. Consequently, the selectivity characteristics of the tuning circuit 16a deteriorates to improve sound quality.
