Title: Chain saw safety protective device
Inventor: KURIFUTON RII MIRA
IPC: B27B17/00
Filed: 1988-04-25
Abstract: PURPOSE: To secure protection from injury due to reversing rotation or the like by providing means to bias a protecting bar attached to a pivot means supported by a bracket toward a rest position of the chain saw in operation. CONSTITUTION: The chain saw is equipped with a U-shaped mounting bracket 1, pivot bolt 8 holds support bar 11, which holds protecting bar 12. Spring 13 is fastened to the support bar 11 and upper member 2 of the bracket 1, and biases the support bar 11 toward engagement with upper member 2 so as to keep the protecting bar 12 in parallel with upper runway of the chain. Bracket 1 holds the first mounting plate 14, and with regard to channel part 17, plate 18 is fixed to the chain saw main body with one or plural bolts 20 for the chain bar. Because the edge of the protecting bar 12 and end fitting 24 extrude beyond the tip of chain saw to engage with surface of the object, the bar 12 turns apart from the chain saw against action of spring 13.

Title: Piezoelectric actuator
Inventor: TAKAHASHI TAKASHI
IPC: F02M51/06
Filed: 1987-04-24
Abstract: PURPOSE:To prevent any destruction of a piezoelectric element and malfunction of an actuator by sealing a fluid between an elastic member and a movable member, and fixing the piezoelectric element to a part of the elastic member. CONSTITUTION:The end face of bellows 25 is fixed to a plunger barrel 27, thereby a fluid is sealed in a chamber 29 formed by the bellows 25, the plunger barrel 27, and a plunger 33. The upper face 25a of the bellows 25 are fixed to a piezoelectric element 13 by which the bellows 25 can be driven. Therefore, if the piezoelectric element 13 is inclined, any eccentric stress is not applied on the piezoelectric element 13, thereby the destruction of the piezoelectric element 13 is prevented as the concentration of the stress does not occur therein. In addition, even if the direction of the pressure to be added to the chamber 29 is changed, the force is applied on the plunger 33 always in the direction of the movement thereof so that any malfunction of an actuator can be prevented.

Abstract: PURPOSE:To improve the service life of heating members by coating a 1st film having specified specific resistance to the parts of base metals which come into contact with a work and coating a film having a prescribed contact angle with a molten metal of lead or tin, etc., on said film. CONSTITUTION:The 1st coating (SiCN) compsn. which has >=10<-2>OMEGAcm specific resistance is formed on conductive base metals 13 which are the heating members in a vacuum chamber 6 by a plasma CVD method, etc. The 2nd film which consists of a TiN component, etc., and has >=10 contact angle with the molten metal essentially consisting of lead or tin is then formed on the 1st film in succession thereto by using the same device. Lead wires, etc. of ICs are soldered to the heating members 13. Since the 1st film having the high specific resistance ad the 2nd film having poor wettability solder are successively formed on the members 13, the shunting of electric current to a circuit board is decreased and the sticking of the solder is prevented. The service life of the members 13 is, therefore, improved.

Title: Outside air temperature detecting device for automobile
Inventor: KOJIMA YASUSHI
IPC: B60H1/00
Filed: 1988-04-26
Abstract: PURPOSE:To prevent an outside air temperature from its misdetection by inhibiting an outside air temperature value from its output in case of a detected engine temperature being not less than the predetermined value when an engine is started. CONSTITUTION:Being based on a signal detected by a temperature sensor M1, an outside air temperature detecting means M2 detects an outside air temperature to be output. While an engine temperature detecting means M3 detects a temperature of an engine E/G to be output to an output action inhibiting means M4. When the engine E/G is in starting and when the detected engine temperature is not less than the predetermined reference value, an inhibition signal is output to the outside air temperature detecting means M2 so that it outputs no outside air temperature detection value for the predetermined time. In this way, the outside air temperature, receiving an influence by heat emitted from the engine E/G when it is started, is prevented from misdetection, and accuracy can be improved.

Abstract: PROBLEM TO BE SOLVED: To reduce power fluctuations due to the outer factor of seawater temperature and the like overlapping low frequency control tone with an optical signal and supplying it at a place, where the optical signal is generated for the first time. SOLUTION: An AGC circuit is provided with a low-noise amplifier 26 generating output proportional to the amplitude of control tone and a difference amplifier 27 connected in parallel to a resistor 28 installed in a line 24, so that it generates output proportional to the current of the resistor 28, namely a drive current toward a laser amplifier 20. When the performance of an optical system fluctuates due to a temperature change, for example, the output power of a facet 22 fluctuates and the amplitude of a corresponding wave pattern in the line 24 also fluctuates. The amplifier 26 responds to the amplitude of control tone, and therefore a signal to a multiplier 29 fluctuates. A comparator 30 detects the fluctuation and resets a device 23.
