Title: Controlling apparatus for piston valve of constant- negative-pressure type carburetor
Inventor: MOTOSUGI KATSUHIKO
IPC: F02M7/17
Filed: 1979-12-18
Abstract: PURPOSE: To improve fuel feeding in acceleration and acceleration performance, by installing a movable cylinder acting as a resistor in the negative-pressure chamber of a constant negative pressure type carburetor and reducing the speed of elevation of a piston valve, while keeping the normal lowering speed.  
     CONSTITUTION: On the piston valve 2 which is fixed with a diaphragm 4 and moves up and down, a jet needle 10 is mounted to control the fuel feeding amount to an intake passage 1a according to the position of the valve 2. In the negative pressure chamber 5 which is formed dividedly by the diaphragm 4, a guide rod 6 is suspended from an upper cover 3, and onto the rod 6, a movable cylinder 7 which moves up and down is inserted. In closing of the valve 2, the movable cylinder 7 contacts with the top part of the valve 2 through a sealing member 8. When the valve 2 is elevated by the negative pressure which is introduced into the chamber 5 through a jet hole 7a, the movable cylinder acts as the resistor for the valve 2.

Title: Reflecting mirror made of plastic film
Inventor: NAKAYAMA MICHIHARU
IPC: G02B5/08
Filed: 1990-06-21
Abstract: PURPOSE:To easily produce the reflecting mirror at a low cost by hermetically fixing the circumference of a plastic film plated with a metal to a flat plate and sealing gas into the spacing between both. CONSTITUTION:The plastic film 2 having a plating layer 3 deposited with the metal, such as silver, having a high reflectivity or plated with this metal on the inside surface is hermetically fixed by means of an annular retainer 4 to the flat plate 1 consisting of, for example, a polystyrene resin. The suitable gas, for example, nitrogen which does not react with the plating layer, is sent from a gas passage 5 into the spacing between the flat plate 1 and the plastic film 2. The parabolic mirror having various focuses is easily produced at the low cost simply only by press-feeding the gas into the spacing between the flat plate 1 and the plastic film 2 in this way.

Title: Ignition-timimg control for internal-combustion engine for car
Inventor: SUEMATSU TOSHIO
IPC: F02P3/045
Filed: 1981-10-14
Abstract: PURPOSE:To prevent generation of knocking by correcting the ignition timing to a smaller value by a prescribed crank angle when the load for an internal- combustion engine is increased sharply. CONSTITUTION:The fact that the load for an internal-combustion engine is sharply increased and the number of revolution is sharply reduced is detected in the steps 214-215. In other words, when the relation Ni<0.9XNi-1 is formed between two revolution speeds Ni-1 and Ni, it means that the revolution speed Ni sharply reduces, compared with the preceding revolution speed Ni-1. When  the relation (Q/N)i>1.1X(Q/N)i-1 is formed on the basis of two air-flow rates  per revolution (Q/N)i-1 and (Q/N)i, it means that a sharp increase of the air-flow rate (Q/N)i per revolution brings the sharp reduction of the number Ni of revolution. In this case, one degree in crank angle is reduced from a standard inginition advance angle theta in the step 216. Thus, generation of knocking can be prevented.
