Patent JP-H08191033-A (JP)
Title: Manufacturing method of laminated ceramic electronic component
Inventor: SHIMOMURA TORU
IPC: H01G4/12
Filed: 1995-01-09
Abstract: PURPOSE: To avoid the release between sheets due to the difference in pressurizing power by a method wherein a number of ceramic green sheets are laminated and after finishing the first pressurizing step at a specific pressure, the second pressurizing step is performed at the specific range of pressure lower than that in the first pressurizing step interposing a heat resistant elastomer on one main surface side. CONSTITUTION: A heat resistant elastomer 18 is interposed between one main surface 2 side and an upper punch 14 of a ceramic green sheet made in a laminated state by the first pressurizing step and then the second pressurizing step is performed at the 50-90% pressure in the first pressurizing step. Through these pressurizing steps, the heat resistant elastomer 18 is elastic-deformed so as to apply the pressure on the pattern absent parts for integration. Thus, the release between sheets can be avoided to relieve the deformation of the ceramic green sheets in the surface direction. Accordingly, the release between the sheets 1 on the pattern absent parts as well as the position slip in the cutting step can be avoided, thereby enabling the reliability upon the manufacturing steps to be improved.

IPC: A23L11/00
Filed: 1981-02-10
Abstract: PURPOSE: To make a filter small-sized and to perform a rapid filtration, by housing the 1st filtering drum in the 2nd filtering drum to perform filtration, and performing natural filtration and forced one respectively by respective drums.  
     CONSTITUTION: When prepared soybean liquid is fed from a feed pipe 8 to flow onto a filter plate 2a of the 1st filter drum 2, the filtered soybean milk falls naturally onto a filter plate 3a of the 2nd filter drum 3. On the other hand, bean-curd refuse, being dehydrated by a dehydrating roll 4 and still remained in filtering holes of the plate 2a, is collected by a sucking pipe 6. Next, the soybean milk, falled on the plate 3a, passes through the plate 3a to be filtered and is collected by a filtrate collecting receiver 1b. On the other hand, fine granules, being dehydrated by a roll 5 and still remained in filtering holes of the plate 3a, are collected to a sucking pipe 7. As a result, the filter is made small-sized, and a rapid filtration is realized.

Abstract: PROBLEM TO BE SOLVED: To hold a gettering site efficiently by providing a gettering layer in a region adjacent to a buried insulating film in the vicinity of the interface between a surface semiconductor layer and a supporting substrate thereby making uniform the thickness of the surface semiconductor layer. SOLUTION: A TEOS film is formed by plasma CVD on a substrate 1 having trenches and the surface of the TEOS film is polished to form a buried insulating film 4 in flush with the substrate 1. A hydrogen ion implantation site 5 is formed symmetrically while being tapered in correspondence with the buried insulating film 4 in underlying silicon and a silicon oxide 7 is grown on the surface of a silicon substrate 6. A partial SOI substrate 9 is then formed by pasting the surface of the substrate 1 having trenches to the surface of the silicon substrate 6 on which the silicon oxide film 7 is formed. Finally, the silicon oxide film 7 is reduced and a gettering layer 10 is formed by hydrogen annealing.

Title: Load controller for combined-cycle plant
Inventor: SATOU SUZUYA
IPC: F01K23/10
Filed: 1979-02-20
Abstract: PURPOSE: To raise the efficiency of operation, by fully loading a gas turbine, shifting the turbine into speed-governed operation and increasing the load on a steam turbine to meet a load increase request when the request cannot be met by the gas turbine being in operation.  
     CONSTITUTION: When a load increases and the load on a gas turbine 1a approaches 100% during the operation of only a gas turbine unit A and a steam turbine, a signal from an electric power detector 29a becomes higher than a set signal on a pressure change operation shifting point setting unit 32. A steam regulating valve 11 is controlled toward closing and the steam turbine is shifted from pressure change operation to speed-governed operation. At the same time, a next gas turbine unit B is started. When another gas turbine 1b reaches a prescribed loaded state, the steam regulating valve 11 is fully opened again to put the steam turbine 12 into pressure change operation. Similar steps are then sequentially effected.

When the switch SW1 is placed at a side (a) to supply the low frequency signal for measurement to the cable way to be measured, the current fed back to the ground line LE through the insulation resistance R0 and stray capacity C0 of the cable way is passed through an amplifier AMP, filter FIT, and rectifying circuit DET to appear at its output terminal OUT as a DC voltage signal. The cable way is therefore measured in the active state.

Abstract: PURPOSE:To detect toner concentrations with the same rotational frequency of developer agitating shafts by rotating plural developer agitating shafts with one rotation driving source between image forming processes at the time of full color development and rotating them in parallel with the development operation at the time of monochromatic development. CONSTITUTION:One rotation driving source 2 rotates developer agitating shafts 11-14 and developing sleeves 41-44 in plural developing devices 51-54.

Consequently, developer agitating shafts 11-14 are rotated with the preliminarily determined rotational frequency to detect toner concentrations between one image forming process and the next image forming process at the time of full color development and to detect them in parallel with development operation at the time of monochromatic development. Thus, L detecting sensors 16-19 having the same characteristic in plural developing device 51-54 measure toner concentrations in the same agitating state.

Abstract: PURPOSE:To increase the adhesive strength for the case located on the reverse side by a method wherein, at the same time when the diffusion process for high density impurity is performed on the surface, photoetching is performed on the semiconductor wafer having a high density diffusion layer of 10<20>atom/cm<3> generated on the back side, and the density of the back side is reduced to 10<20>atom/ cm<3> or below. CONSTITUTION:A P type base layer 3 is formed by diffusion on the N<-> type epitaxial layer 2 which was surrounded by an SiO2 film 8 to be used for insulation isolation, an N<+> type emitter layer 4 and an N<+> type collector contact layer 5 are provided in the base layer 3 and an NPN transistor, having a layer 2 as a collector, is constituted. Then, the reverse side of a semiconductor chip 20 is fixed by adhesion on the bottom face of the case, but as the impurity density of the N<+> diffusion layer 6, located on the reverse side of a P type substrate 1, generated when the layers 4 and 5 were formed, is 10<20>atom/cm<3> or above, no excellent adhesive strength is obtained. Therefore, the impurities are removed until the surface having 10<20>atom/cm<3> or below is exposed by performing photoetching on the layer 6, and the adhesive strength is increased by reducing the density of impurities.

Title: Capstan motor drive control system
Inventor: ISHIKURA MASAO
IPC: H02P1/16
Filed: 1979-02-23
Abstract: PURPOSE: To shorten the lock-in time of a capstan by shorting a capacitor inserted into a phase compensation circuit by nearly equalizing a voltage applied to a capstan motor in potential to normal one when starting VTR.  
     CONSTITUTION: On detecting frequency error voltage 10 varying in proportion to the rotational frequency of capstan motor 7, motor speed decision unit 16 generates level "0" when it is not between detection voltage +E and -EV, and level "1" when so. While limiting a driving voltage to allow capstan motor 7 to turn at a stationary speed, voltage limiting circuit 18 limits the driving voltage by switching circuit 21 only when output signal 17 of motor speed decision unit 16 has level "0". On the other hand, when output signal 17 is at level "0", capacitor C 1  of phase compensation circuit 1 is grounded via grounding circuit 19. Thus, the lock-in time of the capstan can be shortened.
