IPC: G02F1/133
Filed: 1988-02-08
Abstract: PURPOSE:To prevent corrosion, nonuniform discoloration and exfoliation of a light shielding frame in immersion in an aq. acid soln. by covering the light shielding frame consisting of nickel formed by electroles plating with an acid resistant resist. CONSTITUTION:A positive type resist 3 added with the acid resistant material is coated on a glass substrate 1 on which a nickel layer is formed. The resist is dried, exposed and developed to form a prescribed pattern. The glass substrate 1 is calcined by heating the same in order to intensify the adhesion of the positive type resist 3. The pattern of the nickel layer 2 is formed on this substrate by immersing the substrate in an acid mixture and dissolving the nickel of the region not covered with the acid resistant resist 3. Since the acid resistant material is laminated on the metallic layer, the nickel light shielding frame 2 is not corroded even if said frame is immersed into the strong acids.

Title: Intracylinder injection type spark-ignition engine
Inventor: HASHIMOTO EIJI
IPC: F02B17/00
Filed: 1988-02-10
Abstract: PURPOSE:To make it possible to make both ignitability at the time of a light load and power at the time of a high load good by providing a shallow dish part and a deep dish part to a piston and injecting fuel to the shallow dish part at the time of the high load and to the deep dish part at the time of the light load. CONSTITUTION:Fuel is injected from a fuel injection valve 6 which is provided around the outer peripheral part of a combustion chamber 15 mainly to a deep dish part 9 at the time of a light load or injection timing is late, and mainly to a shallow dish part 10 in the first half period of injection at the time of a high load or injection timing is early. With the rise of a piston 8, a swirl in the combustion chamber 15 smoothly moves from the shallow dish part 10 to the deep dish part 9 depending on eccentricity of the center of the shallow dish part 10 and the center of the deep dish part 9. Therefore, at the time of the high load, evaporated fuel gets on a large swirl to avoid excessively rich condition around a sparking plug 1, thereby preventing generation of smolder and smoke in the sparking plug 1. At the time of the light load, evaporated fuel accumulates on the deep dish part 9, gets on a swirl in the deep dish part 9 and is fed to the vicinity of the sparking plug 1 in rich condition, so that ignitability is good.

Title: Detection system for excess-feed of copy paper
Inventor: KAKIYA KEIKO
IPC: G03G15/00
Filed: 1979-03-09
Abstract: PURPOSE: To detect a excess feed of copies (feeding of plural copies at a time) even when the copies are thin by a method wherein the maximum value of the amount of light transmitted through a copy or copies is measured, and an excess feeding is detected through comparison of the maximum value with a specified value.  
     CONSTITUTION: A copy passage detection sensor 16 detects the transmission coefficient of a copy or copies fed along a feed line. A maximum value read circuit 17 takes the maximum value of the output of the sensor 16 when each copy passes by the sensor 16, thereby reading the maximum value of the amount of light transmitted through the copy or copies. The maximum value is converted into a digital value by an analog-to-digital converter 18, before fed to a microcomputer, which compares the maximum value with a specified value and detects a excess feeding.
