Title: Production of thermal recording sheet
Inventor: KOJIMA KAZUO
IPC: B41M5/323
Filed: 1986-05-28
Abstract: PURPOSE:To make the surface of a recording layer suitable for high-speed recording while preventing scumming, by passing a recording sheet having the recording layer comprising microcapsules containing a diazonium salt therein, a coupler compound and a compound capble of generating a basic atmosphere when being melted by heating, through a pressure nip between a metallic roll and a specified elastic roll. CONSTITUTION:In the production of a thermal recording sheet in which a recording layer comprising microcapsules containing a diazonium salt therein, a coupler compound and a compound capable of generating a basic atmosphere when being melted by heating is provided on a base, the recording sheet is passed through a pressure nip between a metallic roll and an elastic roll having a Shore D hardness of 42-70 deg.. If the hardness of the elastic roll is below 42 deg., an excessively high nip linear pressure is required for obtaining a sufficient surface smoothness, so that the useful life of the elastic material itself in operation is extremely shortened. On the other hand, if the hardness of the elsatic roll is above 700 deg. it is difficult to effectively prevent scumming.

Title: Programmable monolithic integrated circuit
Inventor: MASUDA HAJIME
IPC: G11C17/14
Filed: 1979-09-25
Abstract: PURPOSE:To suppress spike current generation in the application of sense current of P-ROM in which a writing circuit is composed of a PNPN circuit, by clamping a voltage at a write terminal at the time of charging-up to a fixed value by a voltage limiting circuit. CONSTITUTION:When precharging current I1 is applied from P-ROM writing WRIT to memory cell Q11, PNPN circuit T is activated. When voltage V3 by electric current passed through terminal C of voltage limiting circuit VOLT causes Zener diode D1' to break down during the above-mentioned period, electric currents flow through resistances R1-R3 to increase the voltage to V4, so that transistor T1'' will be activated. Further, the current flows up to I1, and consequently, terminal A is clamped to voltage V5 increasing through resistance R3. When resistance values of resistances R1-R3 are selected to equalize voltage V5 to a voltage when cell Q11 breaks down, spike current decreases extremely and a write error due to the spike current in a check on a memory element is prevented.

Abstract: PURPOSE:To automatically and directly control the backward speed of a vehicle at a value below a predetermined value with the use of a simple device, by providing a cylinder device which drives a pump for discharging oil at a flow rate corresponding to the speed of the vehicle only during backward travel, and which actuates at a flow rate above a predetermined value to control wheels. CONSTITUTION:A pump 12 is coupled to a differential gear device 2 through an one-way clutch 13 so that the pump 12 is driven by engaging the clutch 13 only during backward travel. The pump 12 discharges oil at a flow rate corresponding to the speed of the vehicle and feeds the same into a cylinder 18. When the speed of the vehicle or the flow rate exceeds a predetermined value the discharged oil flows through an orifice and presses a piston 19 to feed brake oil in a brake master cylinder 21 into a wheel speed control device. With this arrangement it is possible to automatically control the backward speed of the vehicle at a value less than a predetermined value, directly and effectively with no complicated control circuit being disposed therebetween.

Title: Gate turn off thyristor
Inventor: KOBAYASHI TAKASHI
IPC: H03K17/72
Filed: 1982-07-14
Abstract: PURPOSE:To control large capacity current without adding an external adding element by inserting a diode on the way of a positive feedback loop of two transistors(TRs) constituting a gate turn off thyristor. CONSTITUTION:A diode D is inserted between the base of an npn TR Q1 and the collector of a pnp TR Q2. In the figure, IA and IK show anode and casode current of the gate turn off (GTO) thyristor respectively. By connecting the diode, the TR Q1 shows high impedance at the time of turn off and about 1.4V negative bias is applied to the gate because of the voltage drop of the diode D and the TR Q1, so that branched current I2 is reduced, the gate is turned off speedily and current to be used for on and off is increased. Since a current amplification factor alphanpn is generally larger than alphapnp, it is unnecessary to make alphanpn.IK flow and the GTO thyristor can be constituted by the diode with a small current capacity as compared to the case that the diode is externally connected between the cathode side of the GTO thyristor and the earth.
