Title: Magnetic head having excellent wear resistance and production thereof
Inventor: YUKI NORIO
IPC: G11B5/147
Filed: 1988-12-24
Abstract: PURPOSE:To improve wear resistance by forming a magnetic head core from the laminate of core chips formed by subjecting Cr-contg. 'Permalloy(R)' to a nitriding treatment. CONSTITUTION:The core chips 1 consisting of the Cr-contg. 'Permalloy(R)' are annealed for >=15 minutes at 900 to 1,200 deg.C in an atmosphere consisting of >=5% nitrogen and the balance hydrogen to form cured layers 3 by the nitriding treatment. Such core chips are laminated via adhesive layers 4 to form the head core 4. The sliding surface 2 has the state disposed with the hardened layers 3 at equal intervals in the core. The wear resistance is thus improved.

Abstract: PURPOSE:To obtain a light emitting element having a high reliability by reducing a current to be leaked from an end face of an insulating film. CONSTITUTION:An n-type InP buffer layer 2, an InGaAsP active layer 3, a p-type InP clad layer 4 and a p-type InGaAsP cap layer 5 are sequentially laminated on an n-type InP substrate 1 in which an n-type electrode 10 is formed on a rear surface, and a mesa part 8 is partly formed. An Si0N film 7 is formed as an insulating film on the entire surface including the part 8, and an energizing opening 9 for forming a current constriction structure is formed on the part 8 of the film 7. A p-type electrode 6 is formed 1mum or more inside an outer peripheral end face 71 of the film 7 on the film 7 including the opening 9. According to this structure, since a current which does not contribute to light emission flows from the electrode 6 to the surface 72 of the film 7 having high resistivity, a leakage current L from the end face 71 of the film 7 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce electromagnetic noise without increasing the number of components by interposing a varnish layer between a spool held by a pair of field cores having a plurality of meshing claw poles on the outer circumference thereof and the field core. SOLUTION: A spool 14 held by field cores presses, at the end part of opening thereof, the inside of the erected part on the opposite sides of a claw pole 12a. A varnish layer 18 having Shore hardness in the range of 30-80 is formed between the side face of the spool 14 and the inside of the erected claw pole 12a. The varnish layer 18 is formed by dripping a fused varnish between the spool 14 and a field core 12 through the gap of the claw poles 12a from the outside radial direction and then drying and hardening the permeated varnish while turning the rotor. In the rotor, the spool 14 presses the claw pole 12a to suppress vibration thereof and the varnish layer 18 exhibits appropriate elasticity to serve as a buffer for suppressing vibration of the field core 12.

Title: Board material for building and manufacture thereof
Inventor: ONO TOMOHIRO
IPC: E04F13/10
Filed: 1987-12-23
Abstract: PURPOSE: To improve a formed accuracy at a reduced cost by adhering a resin layer to one side of a plate-like base material deflected in a curved surface shape, and holding the curved shape at the resin layer. CONSTITUTION: A rounded ceiling material 1 is entirely formed in a partial cylindrical shape, i.e., an arch-like curved surface shape, and adhered with a resin layer 3 at one side of a rounded deflected plate-like base material 2. The layer 3 performs a role of holding a round shape.

Title: Fuel injection timing controller for diesel engine
Inventor: MAEDA MASAMI
IPC: F02D41/40
Filed: 1987-12-22
Abstract: PURPOSE:To properly control the injection timing and sharply increase the number of revolution by taking-in the number of revolution in plural times per combustion cycle and maintaining the injection timing to an advance angle side, so far as the deceleration having a certain width is not executed. CONSTITUTION:A revolution speed detector 1 detects the revolution speed per combustion cycle of an engine E plural times. For example, when a three- cylinder engine E is sharply accelerated from low speed to high speed, the number of revolution is taken-in plural times per combustion cycle, until a high revolution speed is achieved after the number of revolution is taken-in at a low speed time point, and the variation to aimed value of injection timing control which corresponds to said taking-in is realized. Further, in the sharp acceleration, the delay of the injection timing is suppressed by shifting the injection timing to an advance angle side. Further, in the deceleration over a certain degree, the injection timing is shifted to the delayed angle side, and the injection timing is properly fitted to the number of revolution at the present time point. Therefore, the revolution can be increased sharply, and misfire can be prevented.
