Abstract: PURPOSE: To surely stop an engine even with the malfunction of a fuel cut off valve by stopping the engine by means of an engine stopping means other than the fuel cut off valve when the engine continue to operate abnormally after the key switch is turned off.  
     CONSTITUTION: A time circuit 104 keeps a transistor Q 1  turned on for a predetermined time τ 1  after a time T 1  when a key switch 102 is turned off to close the contact points of a relay 105. Thus the supply voltage of a decision circuit 107 and a control circuit 111 is kept at the voltage of a battery 101 for the time τ 1  after turning-off the switch 102. The time circuit 106 provides a voltage V 3  for low level at a time T 3  after a predetermined period of time τ 2 (τ 2 <τ 1 ). Then, if an oil pressure switch 110 continue to proved a high-level voltage V 5  due to continuous operation of the engine after the switch 102 has been turned off and the malfunction of the fuel cut off valve 103, a high-level voltage V 6  is provided by the decision circuit 107 after a predetermined period of time τ 2  to actuate an engine stopping means.

Title: Radiator
Inventor: HASE YOSHIFUMI
IPC: F01P11/20
Filed: 1980-07-03
Abstract: PURPOSE:To prevent a freeze without decreasing ability of evaporation cooling in a radiator for an engine performing evaporation cooling, by providing an alcohol tank in a position higher than a water tank and equipping a shutoff valve between the both tanks. CONSTITUTION:Cooling water is circulated in the cooling jacket of an engine cylinder, and steam of the cooling waer is condensed and liquefied in a radiator 20. An alcohol tank 23 is arranged in a higher position than a water tank 24. When an engine is not in operation, a shutoff valve 26 is fully opened, then alcohol in the tank 23 flows into the tank 24 and is mixed with cooling water to prevent a freeze at cold time. At normal operation, the shutoff valve 26 is closed, and steam from a steam passage 21 is cooled in a heat radiating passage 30 and dropped into the water tank 24. Alcohol advances to the rearmost flow in the heat radiating passage 30 and is accumulated in alcohol tank 23. In this way, evaporation cooling ability is not decreased and the radiator can be prevented from freezing at cold time.

Title: Optometric device
Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/10
Filed: 1995-03-24
Abstract: PURPOSE: To provide an optometric device simplified in structure and dispensing with observation means of TV camera etc. CONSTITUTION: In the case of examining a left eye EL of an examinee S, a box 23 of a width less than twice a binocular distance at the eye level of the examinee S is brought in front of the face of the examinee. Since a magnifying lens forms an image of the face of an optometrist outside of the position measuring range for the left eye EL of the examinee S, the optometrist's face is invisible to the examinee regardless of the eyesight of the examinee S. Thus, the examinee can easily keep the left eye EL under examination on the box, and an accurate refraction measurement can be performed while looking at an outward distance behind the optometrist by the right eye not under examination.

Title: Lead frame
Inventor: HOKAO MASAYUKI
IPC: H01L23/48
Filed: 1994-04-28
Abstract: PURPOSE:To prevent the leakage of resin at the end part of the tie bar of a lead frame and to prevent the attachment of the resin to the side wall of the lead at the outermost end by farming a notch part at the side wall on the side opposite to the free end of the lead of a protruding part. CONSTITUTION:A notch part 19, which is opened at the side wall on the opposite side of the free end of a lead 1 that is the side of a heat dissipating plate 2, is formed at a protruding part 18 protruding from the side wall of the lead at the outermost end in the extending direction of a tie bar 3. Therefore, even if a space is formed between a protruding protrusion 17 of a metal mold 9 and a protruding part 18 and resin 16 advances along the outer surface of the protruding part 18 when a part of the protruding part 18 is crushed on the resin molding metal mold 9, the resin 16 along the outer surface of the protruding part 18 is guided with the notch part and captured in the notch part 19 and dose not advance forward. During this period, thermal hardening of the resin 16 advances, and fluidity is lowered. Therefore, even if the resin 16 fills the inside of the notch part 19 and outflows, the resin cannot advance forward, and the occurrence of the resin burrs can be prevented.
