Filed: 1989-10-23
Abstract: PURPOSE:To constitute the circuit so that an output current is not varied even in the case there is a temperature fluctuation by connecting a circuit for connecting in series a second PN junction element and a second resistance in parallel to a first resistance. CONSTITUTION:Between a positive voltage source V1 and a ground point, a series circuit of a resistance R1 and diodes D1, D2 is inserted, and to a connecting point (a) of the resistance R1 and the diode D1, a base of an NPN transistor Q1 is connected. Also, its collector is connected to a current output terminal T1, its emitter is grounded through a resistance R2, and also, between the emitter and a ground, a series circuit of a diode D3 and a resistance R3 is inserted. In such a way, to an output current, a current component having a positive temperature coefficient is added, in addition to a current component having a negative temperature coefficient. Accordingly, the circuit can be formed as a constant-current circuit which is not influenced by a variation of an ambient temperature even in a place in which a temperature is varied remarkably.

IPC: F02B33/14
Filed: 1994-10-17
Abstract: PURPOSE:To prevent a mixture gas from blowing through by forming the cylinder lower part with a large diameter, forming a piston skirt part in steps with a large diameter, using the gap between the cylinder large diametric portion and piston small diametric portion as a pump chamber whereto the mixture gas is introduced, and supplying the cylinder with the mixture gas introduced to the intake port from the pump chamber via a scavenging passage. CONSTITUTION:A small diametric portion 2 and a large diametric portion 3 are formed in the upper part and lower part of a cylinder 1, respectively, and the top of a piston 4 is made as a small diametric portion 5 while the skirt part is formed as a large diametric portion 6.

Title: Display device for tape driving direction of tape recorder
Inventor: KAWAI MICHIO
IPC: G11B15/10
Filed: 1985-12-10
Abstract: PURPOSE:To enable a pair of type driving direction indicators to display the forward/reverse driving states of two tape mechanisms, by using a detector which is set at the state of '1' when a reproduction-only mechanism is kept under a tape driving state and otherwise set at the state of '2' respectively. CONSTITUTION:When a mechanism 1 is kept under a constant speed driving mode of tape, a switch 17 is turned on to cut off the base current flowing to a transistor TR 18 via a terminal 9 and a resistance 13. Thus the TR 18 is turned off and therefore a switch 4 gives no effect to a circuit. A switch 3 is turned off when the mechanism 1 kept under the constant speed driving state and also in a forward state. Thus the base current flows via the terminal 9 and resistances 12 and 13. Then a TR 10 is turned on. Thus an LED5 is energized and turned on to show a forward state. While the switch 3 is turned on when the mechanism 1 is set in a reverse state. Thus an LED6 is energized and turned on to show a reverse state.
