Title: High-voltage withstanding head switch circuit
Inventor: TANAKA YOSHIAKI
IPC: G11B15/12
Filed: 1988-07-11
Abstract: PURPOSE:To prevent the recorded content of a tape from being damaged when power supply is cut off by serially connecting three pieces of diodes so that the turning off of the collector current of a transistor used for a current mirror circuit cannot affect the voltage dropping characteristics of a switch changeover control circuit. CONSTITUTION:In case power supply is disconnected by turning off a switch SW0 at time t1, a capacitor C0 starts discharging and the potential at a power supply terminal (b) drops. When the voltage VCE across the collector and emitter of a transistor (TR) Q6 disappears due to the VBE of a TR Q4 and the forward voltage VF across diodes D1-D3 at time t2 thereafter, the collector current of the TR Q6, namely, collector currents of TRs Q3 and Q4 are turned off. Since the turning off of the collector currents of the TRs Q3 and Q4 can be set to a supply voltage which does not follow the a operation of switch changeover control circuit REC/inversional PB when the diodes D1-D3 are inserted, no DC voltage is generated across a switch end (a).

Title: Speed change manipulating device for vehicle incorporating automatic transmission
Inventor: SAKURAI USHIO
IPC: F16H59/08
Filed: 1990-06-29
Abstract: PURPOSE:To prevent erroneous manipulation while maintaining a satisfactory manipulatability by pressing a shift inhibiting means form its one end to its rotary center so as to sustain a position at which an abutting part abuts against a guide pin on a shift lever. CONSTITUTION:In such a condition that a shift inhibiting means is held by a press force by a hold means 8, the drive mode is shifted from its neutral range to the first drive range, or from the second drive range to the first drive range, a guide pin 6 abuts against an abutting part 13 of the shift inhibiting means 7 so that the shifting of a guide pin 6 is inhibited. Accordingly, it is possible to prevent occurrence of erroneous manipulation such that the drive mode is shifted under high momentum, directly from the neutral range to the second drive range or from the second drive range to the neutral range. Further, when the shift lever is manipulated from the above-mentioned condition by a manipulating force overcoming the pressing force of the hold means 8, the guide pin 6 forces the abutting part 13a or 14a to retract so as to rotate the shift inhibiting means 7, thereby it is possible to shift the drive mode from the first drive range to the second driver range or to the neutral range.

IPC: A61M1/14
Filed: 1992-05-22
Abstract: PURPOSE:To change a humor treating apparatus without halting treatment by a method wherein at least one inflow port side of a humor treating apparatus is branched off and a passage on the branched side is connected directly to the outflow port side of the humor treating apparatus to form a bypass passage. CONSTITUTION:In normal treatment, a bypassing passage 11 is pinched with forceps or the like to close. Under such a condition, when a blood pump is driven, blood is sucked up from a human body through a passage of a blood pump mounting part 10 and flows through a circuit. By so doing, undesired matters in blood is removed with a blood component adsorbing device and the undesired matters caused by renal insufficiency, drug intoxication or the like is dialyzed or removed with a blood dialyzer. Normalized blood after the removal of the undesired matters by the dialysis and filtration is returned into a human body with a blood return port 2. When the blood component adsorbing device gets saturated with the continuation of the application, a closing is made before and after the blood component adsorbing device with forceps so as to make a bypass 11 communicate. This constitution lets the blood sampled flows direct into the blood dialyzer through the bypassing passage 11.
