Patent JP-S56144563-A (JP)
Title: Manufacture of base for ceramic package
Inventor: TAKASHIMA KAZUHISA
IPC: H01L21/48
Filed: 1980-04-11
Abstract: PURPOSE:To obtain a highly accurate base for a ceramic package by a method wherein unbaked ceramic substrates laminated into a multilayer structure are cut on the basis of a wiring metallized layer pattern on the ceramic substrate or the edges of a hole in the semiconductor element mounting portion, and integrally baked. CONSTITUTION:Unbaked ceramic substrates 2, 4 and 6 are piled up, and the centers of a hole 15 in the substrate 4, a wire bonding hole 18 and a pellet mounting metallized layer 17 are aligned with each other by using an optical system 19. Then, an edge P of the hole 15 or an inner edge L of a wiring metallized layer 3 is detected, and on the basis thereof, a cutting-shaping edge 13 is lowered to cut the outer edges of the substrates 2, 4 and 6, which are then baked. The base 7 formed by said constitution has accurate spacings Lx and Ly between its outer edges and the inner edges of the wiring metallized layer 3 and Px and Py between said outer edges and the hole 15, and the errors, which include the shrinking errors in baking the substrates and the errors in cutting, can be made less than + or -0.2mm.. Accordingly, accurate positioning can be effected by simply contacting the outer edges of the base closely with reference sides, and a wire or pellet can be automatically bonded.

Title: Resonator and band-pass filter using same
Inventor: OKAMURA NAOTAKE
IPC: H03H7/09
Filed: 1986-03-04
Abstract: PURPOSE:To obtain a prescribed Q and the miniaturization and low cost by forming a capacitor electrode pattern and a coil pattern on the front and rear face of a dielectric base as a prescribed pattern so as to constitute a resonator comprising a lumped constant element. CONSTITUTION:Capacitor electrode patterns 2, 3 and coil patterns 4, 5 are formed to a front face 1a and a rear face 1b of the dielectric base 1. The capacitor electrode patterns 2, 3 are opposed to both faces of the dielectric base 1 to form a capacitor C whose capacitance depends on the dielectric constant epsilonof the base, thickness and the opposed area of the capacitor electrode patterns. On the other hand, a part of the coil patterns 4, 5 is connected to the capacitor electrode patterns 2, 3, and the other parts are connected electrically through, e.g., a through hole 6. Since the through hole 6 and the coil patterns 4, 5 connected via the base end faces form a coil in terms of high frequencies, denoting the inductance as L, then the resonator forms an LC parallel circuit equivalently.

IPC: H01L29/792
Filed: 1989-02-28
Abstract: PURPOSE:To prevent the change of characteristics caused by the deviation of alignment by a method wherein an erasing gate is formed by using a diffusion layer, and a floating gate and a controlling gate are patterned so as to overlap the erasing gate. CONSTITUTION:By diffusing N-type impurity, a drain 46, a source 47 and an erasing gate 43 are formed on a P-type Si substrate 41. On the upper surface of a substrate 41 between the drain 46 and the source 47, floating gates 44, 44b are so formed that at least a part of the floating gates overlaps with the gate 43. On the upper surface of the gate 44, a controlling gate 45 is formed which controls the gate 44 by capacitive coupling. By this constitution, the alignment deviation between the gate 41 and the gate 45 is not caused, so that the change of characteristics is little, and the deterioration of function as a flash EEPROM can be prevented.

Title: Method for interpolating free curve in numerical controller
Inventor: OTSUKI TOSHIAKI
IPC: G05B19/4103
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To attain multi-dimensional free curve interpolation including axes other than three basic axes for regulating space. SOLUTION: A secondary functional formula fi(t) passing three continuous points Pi-1, Pi, Pi+1 is found out from a provided sequence of points. A distance s1 between the points Pi-1, Pi+1 and a distance S2 between the points Pi, Pi+1 are found out, fi(0)=Pi-1, fi(s1)=Pi and fi(s1+s2)=Pi+1 are set up and the coefficient vectors (a) to (c) of fi(t)=at2+bt+c are defined to find out the secondary functional formula. The functional formula fi(t) is differentiated to find out the differential vector Pi'=fi' (s1) of the point Pi. A free curve connecting between points is found out and interpolated by respective axial coordinate values of respective given points and the differential vectors of respective found points.  Since the differential vectors of respective points are found out without utilizing the graphic feature of three-dimensional space, a free curve including all axes can be interpolated even when interpolating axes are increased up to four axes, five axes,... by a rotary axis or the like other than three basic axes.

Title: Pattern forming method
Inventor: SUGIHARA OSAMU
IPC: G03F7/26
Filed: 1988-02-29
Abstract: PURPOSE:To reduce frequency in occurrence of faults, the amount of consumption of plating liquid used and deterioration by separating a resist pattern in an optional stage before plating processing after adding a catalyst in pretreatment for plating processing. CONSTITUTION:After adding the catalyst in the pretreatment for plating processing, the resist pattern 3 is separated in the optional stage before plating processing and plating processing is performed to a substrate 2 with a transparent conductive film pattern where the resist pattern 3 is separated. Therefore, a plating layer 5 is not formed on the resist pattern 3. Thus, the pieces of the plating layer separated with the separation of the resist pattern can be prevented from adhering again. Since plating processing is performed only to the parts of the transparent conductive film patterns 1a and 1b where plating processing is performed, the amount of consumption of the plating liquid is reduced and the deterioration hardly occurs.

Title: Developing device and image forming device
Inventor: SATO SHOGO
IPC: G03G15/08
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a developing device by which the residual amount of developer is stably detected by preventing the scattering of the developer at the time of stirring and carrying the developer at the inside of a developer chamber. SOLUTION: An agitator 53 and a cleaning member 54 are integrally formed at a rotary shaft 55 in a toner housing chamber 52 having a nearly circular cross-sectional shape. When the agitator 53 is rotated and driven, a sheet member 53b having flexibility is moved to an inner surface part 52a while rubbing it in a bent state, and simultaneously the wiper 54b of the cleaning member 54 cleans a light-transmitting window 56b provided at the side part of the toner housing chamber 52. The width of the sheet member 53b is made larger than that of an aperture part A in a direction along the rotary shaft 57 so that the deflection is not released even though the sheet member 53b reaches the aperture part A.  Thus, the scattering of the toner due to the release of the deflection of the sheet member 53b is prevented, and the erroneous detection of toner residual amount by an optical method through the light-transmitting window 56b is not caused, so that stabilized and highly reliable toner residual amount detection is achieved.

Title: Soft ground improvement work by sand pile
Inventor: MISAKA KAZUMA
IPC: E02D3/08
Filed: 1983-03-22
Abstract: PURPOSE:To effectively and exactly form given sand piles by a method in which the detection of the soil quality of the base ground is made during the penetration work of a hollow pipe for forming sand piles. CONSTITUTION:In forming sand piles where a hollow pipe 1 for forming sand piles is used, the hollow pipe 1 is penetrated to a given depth B into the ground from the ground's surface A where sand piles are to be formed, during which period the soil quality of the base ground is detected at each depth (GL1-GLn) by any testing method. While pulling up the hollow pipe 1, the discharging and compaction of sand in the hollow pipe 1 are made by a sand discharge and compacting part 3 to form sand piles up to the ground's surface orderly. Since the soil quality of the base ground at each depth is detected during the penetration period of the hollow pipe 1, the method to form sand piles at each depth can be determined before the forming process of sand pile, and uniformly improved ground can be exactly formed at this point.

Title: Contactless igniting device
Inventor: KASHIWAZAKI SEIICHI
IPC: F02P5/155
Filed: 1978-04-24
Abstract: PURPOSE: To provide a contactless igniting device wherein an angle of delay of a constant value is obtained by an AC generator and a simple circuit using a small capacitor regardless of the rotational speed of an engine.  
     CONSTITUTION: In the case where switch means 21 is closed, an AC voltage generated by an AC generator 1 is applied to a transistor 3 through a resistor 2. When a primary current flows to an igniting coil 14 in a state where the AC voltage is in negative state and the voltage is converted from the negative state to the positive state, the primary current is interrupted and a spark is generated in an ignition plug 15. In the case where switch means 21 is opened, the AC signal is converted from the negative state to positive state, and a charge current flows in a capacitor 16 until it reaches the positive peak. While the charge current flows, the transistor 3 is connected in the interrupted state. When the AC signal passes through the positive peak, the transistor 3 becomes conductive, and a spark is generated in the ignition plug 15. For this reason, the ignition timing is delayed at a predetermined angle.

Title: Method and apparatus for filling into circular fabric while z shaped turn-over part is formed to bag material flattened to strip like form
Inventor: FURANKU BOOSE
IPC: D03D37/00
Filed: 1982-03-24
Abstract: Z-shaped folds are formed in a tubular film and the latter is inserted into a woven tubing as the latter is woven and collapsed in a circular loom. The tubular film is squeezed between pairs of pinch rollers and is then inflated to form a bubble, which is supported by annular surfaces at the weaving ring and at a distance from the latter so that the bubble bulges between the annular surfaces so as to form an annular bead. A Z-shaped annular fold is formed in that tubular film in that edge portion of said annular bead which is remote from the weaving ring is pushed into the latter. For the fixation of the Z-shaped folds e.g., at the portions which will subsequently form the rims at the open ends of the bags to be made, it may be desirable to apply adhesive to the tubular film above the Z-shaped folds and to force said adhesive-coated portions against the inside surface of the surrounding woven tubing.
