Patent JP-S62118559-A (JP)
Title: Semiconductor device
Inventor: YOSHIIE MASANOBU
IPC: H01L27/04
Filed: 1985-11-18
Abstract: PURPOSE:To prevent silicide reaction between a metal oxide film such as a Ta2O5 film used in a capacitor part and a silicon substrate, to prevent reaction between the metal oxide such as Ta2O5 film and a polycrystalline silicon electrode located on the metal oxide film such as the Ta2O5 film, to reduce leaking currents and to prevent reduction in capacitance due to heat treatment, by providing a silicon nitride film. CONSTITUTION:A silicon nitride film 102 formed on the surface of a silicon substrate 101 is used to prevent silicide reaction between a Ta2O5 film and the silicon substrate when the Ta2O5 film is formed in the succeeding process. The diffusion coefficient of oxygen in the silicon substrate 101 is not oxidized through said Ta2O5, and the capacitance is not reduced. A silicon nitride film 104, which is formed on high dielectric-constant material, is formed by, e.g., a pressure reduced CVD method. Then, the silicon nitride film is thermally oxidized and a thin silicon oxide film 105 is formed. The best advantage of this oxidation is the fact that the basis film is grown by the oxidation of the surface of the silicon substrate 101 through pinholes in the Ta2O5 film 103 and the silicon nitride film 102.

Title: Semiconductor memory
Inventor: YOSHIMOTO HIROYUKI
IPC: G11C11/401
Filed: 1984-12-10
Abstract: PURPOSE:To improve actual mounting density as a whole by receiving specific signals, generating the first and second selective signals inside the chip, and reducing the number of memory pins to miniaturize package. CONSTITUTION:The device is equipped with a delay circuit 12 which receives a line strobe signal RAS formed outside the IC inside an IC20 and uses this output as a row strobe signal CAS. This means that the device performs line selection when the signal RAS is at a VOL level and performs row selection when the signal CAs is at a low level by using as the signal CAS the signal delayed only for a period of t0 of this RAS signal, thus enabling omission of CAS signal input pins as compared with the conventional circuit.

Title: Loop-like plastic molding and its manufacture
Inventor: HIRAMOTO KOJI
IPC: B29C45/17
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce man-hours required for manufacturing a loop-like plastic molding by molding the plastic molding by a two-layer structure. SOLUTION: Before second high temperature resin is cured, first and second pressurizing cylinders 8, 10 are operated, pressure is alternately applied to the second resins poured from first and second pouring gates 3, 4 little by little, and slightly longitudinally moved. When the second resins receive the alternate pressures, weld W is dispersed, and glass fiber is oriented at random. The second resin is cooled and cured to form a core layer 2 having mechanical strength and suitable elasticity required thereby. Thus, since the mixed glass fiber can be oriented at random by eliminating the weld of the core layer instead of a mandrel, a loop-like plastic molding of a two-layer structure having the required strength and elasticity can be formed.

Title: Load cell weigher
Inventor: YAMASHITA TAKAHARU
IPC: G01G23/02
Filed: 1989-10-05
Abstract: PURPOSE:To make a load from a saucer act in a straight line and to prevent generation of a moment in a strain-generating body by forming a projecting part with a gap given between the base of an arm and the saucer, the gap allowing the projecting part and the saucer to come into contact with each other at a prescribed position whereat a weighing capacity is exceeded. CONSTITUTION:A projecting part 14 is formed monolithically on the base 10 of an arm 9, and a gap between the upper end of the projecting part 14 in a free end and the lower side of a saucer 12 is set in a dimension which does not allow the contact of the saucer 12 with the projecting part 14 until a load given to the saucer 12 reaches a weighing capacity, though the shape of a flexible member 13 changes due to the load. When the load F exceeds the weighing capacity, the amount of the change in the shape of the member 13 becomes large, the lower side of the sauce 12 comes into contact with the projecting part 14 and also the lower side of the free end 7 of a strain-generating body 4 comes into contact with a stopper 8. Even when the load F is large considerably, it acts along a vertical line whereon the saucer 12, the projecting part 14, the base 10, the free end 7 and the stopper 8 are positioned. As the result, a moment due to an excessive load does not generated in the strain- generating body 4.

Abstract: PURPOSE:To prevent the excitation shaft of a vibration generating machine from being drawn into an atmospheric pressure and temperature tank when the atmospheric pressure in the atmospheric pressure and temperature tank drops by providing a pressure balance part between the wall surface of the tank and the excitation shaft of the vibration generating machine. CONSTITUTION:The in-tank pressure P1 operates on the upper end surface 6 of the excitation shaft 4 and the force corresponding to the surface area is applied to the excitation shaft 4, when the in-tank pressure P1 is negative, the force operating on the excitation shaft 4 is the force toward in the tank. The in-tank pressure P1 is applied to the 2nd cavity 12 of the excitation shaft 4 through a communication pipe 21 and air is cut off by a 2nd diaphragm seal 16 and a 3rd diaphragm seal 18, so the in-tank pressure P1 operates on the reverse surface 7-2 of a collar part. The surface area of the upper end surface 6 is equal to the area of the reverse surface 7-2 of the collar part, so the force operating on the reverse surface 7-2 of the collar part is counter to the force toward in the tank, so the forces are balanced and the excitation shaft 4 is not drawn into the tank.

Title: Bus connection type multiprocessor device
Inventor: TAKAHASHI SHINJI
IPC: G06F15/173
Filed: 1990-09-29
Abstract: PURPOSE:To prevent the generation of troubles such as the increment of electric load or the generation of signal delay by forming wiring areas between respective power supply lines and between respective ground lines and forming bus lines in the wiring areas. CONSTITUTION:Since the power supply lines 21 on a power supply layer 20 are formed by wring patterns directed only in one direction (x direction), a surface margin can be formed over a wide range among respective lines 21. Since the ground lines 31 on a ground layer 30 are formed by wiring patterns directed only in the direction (y direction) rectangular to the lines 21, a surface margin can be formed over a wide range also among the lines 31. Thereby, bus lines 22, 23 can be formed in the space parts, so that the wiring of the bus lines 22, 32 can be shortened or the wiring patterns of respective lines can be simplified. Consequently, the generation of troubles such as the increment of electric load and the generation of signal delay can be prevented.

IPC: H04M3/24
Filed: 1988-10-17
Abstract: PURPOSE:To simplify a circuit constitution and to easily cope with the alteration of the number of data digits as well by using a read-only memory. CONSTITUTION:When the sum of '1' of binary addresses is in an even number, '1' data are stored as a parity inspection acceptance, and when the sum of '1' is in an odd number, '0' data are stored as a parity check error. For example, when data '11101011' are sent from a control circuit 1 to a memory circuit 5, and the data '11101011' and the parity data '0' are inputted to a read-only memory 6 as nine-bit address data '011101011' without the error, the data '1' designated by the address information are outputted to a parity check line B, that is, the parity check indicates the acceptance. Thus, the circuit constitution is simplified, and the alteration of the number of the data digits can be easily coped with, as well.
