Patent JP-H029031-A (JP)
Title: Optical recording medium
Inventor: ITO MASAKI
IPC: G11B7/243
Filed: 1988-06-27
Abstract: PURPOSE:To improve weatherability and oxidation resistance and to improve the stability of signal quality by forming a recording film of a required crystal film and varying the contents of specific component elements in the film thickness direction. CONSTITUTION:The recording film is formed of the crystalline film essentially consisting of tellurium, selenium, lead, nitrogen, and oxygen. The contents of the lead, nitrogen and oxygen are increased at the boundary of the recording film to suppress the generation of granular projections in high-temp. and high- humidity environment. The oxidation of the recording film is prevented if the contents of the lead, nitrogen and oxygen in the central part of the film thickness are decreased to decrease the average content. As a result, the weatherability and oxidation resistance are enhanced and the quality of the recording and reproducing signals is stabilized over a long period of time.

Title: Bumper rubber
Inventor: IZUMI HIROYUKI
IPC: F16F1/36
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive bumper rubber causing no buckling. SOLUTION: This bumper rubber 2 installed on either of an opening and closing member and a peripheral edge of an opening for installing the opening and closing member is made of rubber or thermoplastic elastomer, and a recessed part 18 is formed at a pressure receiving face 16 on the top. Plural recessed grooves 20 continuously provided over the whole peripheries, are formed on the side face of the bumper rubber. The farther the respective recessed grooves are away from the pressure receiving face 16, the deeper the grooves 20 are formed so that the outside diameter of remaining central part becomes smaller as it far from the pressure receiving face 16. Thus, a bumper rubber 2 made up of a single member can be obtained, and the cost of the bumper rubber 2 can be reduced and the bumper rubber 2 can be prevented from causing backling.

Title: Method for electroplating ceramic
Inventor: SAKAMOTO KAZUMI
IPC: C25D5/54
Filed: 1991-06-04
Abstract: PURPOSE:To prevent burning at an electric contact at the time of forming an electroless plating film on a ceramic and electroplating the film by plating with a small current at the initial stage of electroplating and then plating with a heavy current. CONSTITUTION:The surface of an insulating ceramic member is degreased with alkali, cleaned, etched and activated by the deposition of a metallic palladium nucleus. The member is dipped in a Cu electroless plating soln., etc., to form a thin Cu plating film on the member surface. The ceramic member 1 having this Cu electroless plating film is supported on a rack 2 at a contact 3, and a current is applied to the rack 2 through the contact 3 in an electroplating soln. to electroplate the film with a metal. In this case, the current density is reduced at the initial stage, the current density is increased when an electroplating film is formed in specified thickness, and normal electroplating is conducted. The thin Cu electroless plating film is burned off at the contact 3 of the rack 2, and the current supply is not stopped.

IPC: H01L21/027
Filed: 1982-09-14
Abstract: PURPOSE:To prevent the storage of charges to the positioning mark even when the resistance of a substrate to be irradiated is high by coating a region containing the electron-beam scanning region of the surface of the substrate with a foundation metallic film with a conductive connecting section extending on the surface of the substrate and forming the positioning mark made of a metal at the central section of the foundation metallic film through plating, etc. CONSTITUTION:The substrate 1 having high resistance is coated with the foundation evaporating film 2, and a cross-shaped plating metal layer 3 as the positioning mark is formed at the central section of the surface of the film 2. The connecting section 4 extending on the substrate 1 from one side of the foundation evaporating film 2 is formed previously at that time, electron beams are irradiated under the state, and the plating metal layer 3 as the mark is positined. Accordingly, charges do not store in the plating metal layer 3 because there is the connecting section 4 extending on the substrate 1 even when the resistance of the substrate 1 is high, and high detecting signals can be obtained.

Title: Hybrid power train system for vehicle
Inventor: OKANE HIROAKI
IPC: B60L50/16
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To reduce consumption of a power and to effect the smooth starting of an engine. SOLUTION: A first motor is arranged in a manner to be coupled to the crank shaft of an engine through a clutch starts an engine in a way that the number of revolutions lower than the number of idling revolutions forms the target number of revolutions. In this case, drive torque of the first motor is outputted to a maximum and the number of revolutions of an engine is gradually raised. When the number of revolutions of an engine reaches No, an injector is operated and fuel is injected in an engine. Torque is outputted and the engine increases the number of revolutions, and output torque of the first motor integrally coupled to the engine is decreased. When a decrease amount exceeds a given value ΔTm, it is decided that the engine effects complete explosion, starting drive of the first motor is stopped.  This constitution shortens the starting time of an engine and saves power consumption, prevents the generation of sound vibration through continuous application of torque and provides excellent startability.

Title: Minimum value arithmetic unit and its control
Inventor: WAKAUMI HIROO
IPC: H01L21/8234
Filed: 1987-06-26
Abstract: PURPOSE:To attain broad dynamic range, low power consumption and direct interface by using an electric charge in place of a current so as to apply minimum value arithmetic processing. CONSTITUTION:This is the system to control a minimum arithmetic unit obtaining a minimum value of two input signals X, Y for the fuggy logic operation. During the charge injection period, the input signal X is applied to the 1st electrode 13, 0V is fed to the 2nd electrode 14 to make the potential of a barrier potential generating means beneath the electrode lower thereby storing an electric charge to a charge storage means just beneath the 1st electrode 13. Then for the charge transfer period, an input signal Y is applied to the 2nd electrode 14 to transfer the electric charge corresponding to the minimum value of the signals X, Y under the control electrodes 15-18. Thus, the dynamic range is not controlled by a current mirror circuit but made wide and since the voltage signal corresponds one to one to the electric charge, no interface circuit is required in excess and the signal is converted simply and power consumption is less because of the arithmetic operation of electric charges.
