Title: Energy conservation cycle internal combustion engine
Inventor: TANIGAWA HIROYASU
IPC: F02F3/00
Filed: 2000-11-07
Abstract: PROBLEM TO BE SOLVED: To solve the problem in the existing reciprocating internal combustion engine in which a small gasoline engine with the maximum thermal energy rate at the top dead canter and non-rotation emission thermal energy loss about 50% has the lowest heat efficiency about 15%, while a marine large diesel engine with maximum delayed combustion and non-rotation emission thermal energy loss about 20% has heat efficiency of 55% at maximum, howere it is not applicable to an automobile or the like. SOLUTION: By two-stage combustion, the maximum combustion pressure is increased approximate eight times (16 MPa) as high as the compression pressure (2 MPa), and only the emission time of thermal energy is delayed to attain thermal efficiency about 70% by completely combusting with theoretical air fuel ratio in reduced-diameter main combustion chamber superheated steam injection separation combustion in substantially closed container. By heating exhaust temperature in 100 deg.C, in an enlarged-diameter combustion chamber very high speed mixing two-stage combustion and exhaust heat recovery heat exchanger, heat is recovered and fed to a reduced- diameter main combustion chamber heat exchanger repeatedly, thereby increasing heat recovery to the limit.  Combustion gas such as CO2 or the like is dissolved, mixed and fixed in the cooled superheated steam condensed water and discharged so that exhaust of CO2 or the like is decreased to zero or a little.

Title: Metering device of camera
Inventor: MOTOMURA KATSUMI
IPC: G03C3/00
Filed: 2000-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a metering device of a camera, which operates at low voltage and operates stably, regardless of use environments. SOLUTION: When subject luminance is low, since the resistance value of a CdS 16 is greater than the sum of a resistor 76 and a variable resistor 86, the base current of a transistor(TR) 80 is smaller than the base current of a transistor(TR) 81 immediately after a photometric switch 75 is turned on. Since the C-E voltage of the TR 80 rises high, the base current of the TR 81 increases and the inter-C-E voltage drops, thereby decreasing the base current of the TR 80. The TR 80 is shut off and the TR 81 is conducted by this feedback effect, therefore the primary and secondary TRs 80 and 83 are conducted successively, and a solenoid 60 is energized and is changed over to a diaphragm of a larger diameter.  When the subject luminance is high, the resistance value of the CdS 16 is low, and therefore the TR 80 is conducted by reverse operation and since the TR 81 is shut off, the solenoid 60 will not be energized and the small diaphragm remains being held intact.

IPC: G11B7/125
Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser device which can protect an LD and facilitates a building-in process of an LD and dealing an LD. SOLUTION: In a normal state, an N-channel FET 2 turns on, and an anode and a cathode of an LD 1 are substantially shorted through the FET 2. As a result, when static electricity is applied to a terminal 3, almost all the static electricity flows to the FET 2. Thereby the LD 1 is protected from the static electricity. When the LD 1 is driven for light emission, the FET 2 is turned off by applying a control voltage (negative potential) to a terminal 4 connected with a gate of the FET 2. In this state, when a driving current is applied to a terminal 3, the driving current flows in the LD 1, which generates a light.
