Title: Level conversion circuit
Inventor: TOMITA KAZUHIRO
IPC: H03K19/018
Filed: 1990-03-19
Abstract: PURPOSE:To prevent the occurrence of skew in an output signal by connecting the collector of a PNP transistor(TR) to the base of a phase division TR, connecting the emitter of the PNP TR to a power supply and connecting its base to the power supply via a resistor and to the output terminal of a differential circuit. CONSTITUTION:The collector of a PNP TR 9 is connected to the base of a phase division TR 4, the emitter of the PNP TR 9 is connected to a power supply VCC, its base is connected to the power supply VCC via a resistor R8 and to the output terminal of the differential circuit 1. In this case, only when the PNP TR 9 is turned off from its on-state based on the operation of the differential circuit 1, since the PNP TR 9 is turned off with a delay from the operation of the differential circuit 1, the phase division TR 4 is operated in addition by the delay time of the PNP TR 9. Thus, skew is adjusted without changing the through-rate of an output signal Vout by the operating time of the PNP TR 9.

Title: Write permit ring detecting device of magnetic tape reel
Inventor: TAKAHASHI RIYUUICHI
IPC: G11B15/07
Filed: 1984-04-09
Abstract: PURPOSE:To obtain an effective detecting device of write permit rings, by supplying a gas from a static converter to a jetting nozzle facing the ring fitting position of a reel and sending out the detecting output of the ring by controlling a switching element in the static converter in accordance with the pressure change of the supply gas. CONSTITUTION:Pressurized air P1 is generated into the air through a needle valve V3 after passing through an orifice V1, but the air P1 after passing through another orifice V2 is supplied to a jetting nozzle 11 through a pipe 23. When a ring, to which pressurized air P2 is supplied, is not fitted, the pressurized air P1 and P2 is blown against the bottom surface 6a of the ring fitting groove 6 of a reel 4 through the outer peripheral nozzle 12 of the nozzle 11 and, therefore, the atmospheric pressure in the nozzle 11 is low. When the ring is fitted to the groove 6, fluid resistances of each nozzle 11 and 12 increase and the pressure PB of the orifice V2 at the discharge side also increases. As a result, a permanent magnet 25 is brought upward and turns on a lead switch LS and a detecting output DO is sent out through a power source E, and thus, the fitting of the ring is detected.

Title: Wire dot printing head
Inventor: ANDO KOICHI
IPC: B41J2/28
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the irregularity of spring force, by constituting the title printing head so that the support end of a leaf spring is held by the protuberance formed to the upper surface of the outer periphery of a spacer and that formed to the under surface of the outer periphery of a yoke and the under surface of the support end of the leaf spring is supported by the protuberance formed to the upper surface of the inner periphery of the spacer. CONSTITUTION:Since the outer periphery of the support end 11b of a leaf spring 11 is held by the proturberance 12a of a yoke 12 and the protuberance 13a of a spacer 13, said leaf spring is not polled off, and the grasping by a pair of the proturberances 12a, 13a and the support by the proturberance 13b provided to the upper surface 13i of the inner periphery of the spacer 13 respectively become a linear grasping/support state. Because of this, the leaf spring receives no effect of the surface roughness of the yoke 12 or spacer 13. Since the support end 11b of the leaf spring 11 is held and supported between the outer and inner peripheries of the spacer 13, a reaction force distance can be increased and each reaction force can be reduced in order to obtain the same spring force. As a result, no irregularity is generated in the spring force of the leaf spring 11 and the leaf spring 11 can be held only by the press clamping due to a clamp spring.
