Title: Clock warranting circuit
Inventor: MIHASHI KAORU
IPC: H03L7/08
Filed: 1995-02-24
Abstract: PURPOSE: To evade malfunction due to clock changeover by controlling an internal clock generated by a VCO and an input clock so that their phases are always in matching with each other and selecting either clock depending on the result of discrimination of disturbance of the input clock. CONSTITUTION: A frequency divider 5a (5b) applies 1/N frequency division to an internal clock CK 11 (input clock CK i) and outputs a signal 13 (14), and a level discrimination device 2 discriminates disturbance of the CKi and outputs a selection signal 12. A PLL circuit 4 outputs a voltage level 15 to allow the CK 11 to follow up stabilize the CK 11 depending on the presence/absence of a phase difference between the signals 13 and 14. Then a selector 3b selects the level 15 or a voltage level M to make the VCO 1 stable depending on the signal 12 and outputs the selected signal to the VCO 1 as a control signal 16. Furthermore, a selector 3a selects either the CKi or the CK 11 depending on the signals 12 and outputs the selected clock as an output CK.  Thus, even when the CKi is faulty and the CK 11 is selected, a stable clock signal is given to the circuit to prevent the malfunction of the system.

Abstract: PURPOSE:To make it possible to harden a resist effectively and reliably by a method wherein the substance, with which the organic high molecular material of resist will be bridged, is coated on the resist after patterning, and the organic high molecular material of resist is hardened. CONSTITUTION:After a pattern has been formed using a photoresist, a coating film containing a crosslinking agent of the organic high molecular material of resist is formed on a resist pattern, the resist and the coating film are reacted with each other, and then the coating film is removed. Pertaining to the bridge material, bisphenol epoxy, novolac epoxy and the like can be used. These bridging agents are coated independently on the resist, desirably mixed into a solution or resin. The resin of PMMA, PVA and the like may be used as the above- mentioned resin, but it is necessary that the resist and the bridging agent are properly combined so that the resist containing the bridge agent are not bridged. As a result, the improvement in heat-resisting property and dry etching resisting property can be achieved.

IPC: B41J2/36
Filed: 1987-03-19
Abstract: PURPOSE:To enhance the quality of a recording image by eliminating the difference in the density between each of rows, by indicating a preheating time to the heat generating element on an upstream side on the basis of the OR pattern of the recording pattern due to the adjacent heat generating element rows on a downstream side and the recording pattern on the upstream side. CONSTITUTION:When an odd number cycle is judged, for example, the OR pattern due to the shaded part pattern of the odd number cycle 1 and the shaded part pattern of an even number cycle 4 is set to a driver 15 through a signal wire Sb. The time t3 for preheating a thermal transfer ribbon 9 by heat generating elements DA1-DA8 is set so as to be shorter than the time t1 required in melting the ink on the thermal transfer ribbon 9 or reducing the viscosity thereof to transfer said ink to recording paper 10. Since the supply of a current for the time t3 is already finished with respect to the recording pattern of the odd number cycle, the sufficient current supply time herein is t1-t3. Since the thermal transfer ribbon 9 is preheated by the heat generation of odd number rows and heat is accumulated, a current is supplied to the heat generating elements DB1-DB8 corresponding to the recording pattern of the even number cycle for a time t2 being set with due regard to this accumulation quantity of heat.

Title: Paste type plate
Inventor: FURUKAWA ATSUSHI
IPC: H01M4/24
Filed: 1987-03-19
Abstract: PURPOSE:To increase mechanical strength by preparing paste by kneading electrode active material and a specified conductive material. CONSTITUTION:Paste prepared by kneading an electrode active material, a nickel whisker conductive material, and a binder is applied to a substrate. For example, 80 ptswt active material such as nickel hydroxide, 10 ptswt nickel whisker having a diameter of about 1mum and a length of several tens mum serving as conductive material, 4 ptswt cobalt are kneaded with 1% carboxymethylcellulose aqueous solution to prepare paste. The paste is applied to a nickel net and dried to form the cathode plate of a storage battery. Since the nickel in the paste is whisker instead of powder, mechanical strength is increased and coming off of the active material is prevented. Therefore, the cycle life of a battery is increased.

Title: Semiconductor light-emitting device

IPC: H01L33/24
Filed: 1987-03-18
Abstract: PURPOSE:To improve the temperature characteristics of an end-surface light- emitting diode extending over a wide temperature range by forming an active layer and a clad layer into a groove shaped to a V-shaped sectional shape from the end surface of a semiconductor base body. CONSTITUTION:A P-type InP layer 2 is grown on the plane (100) of an N-type InP substrate 1. A groove, a cross section of which has a plane (111) B, is formed in depth reaching to the substrate 1. An N-type InP clad layer 3, an InGaAsP layer 4, a P-type InP clad layer 5 and a P-type InGaAsP layer 6 are grown inside and outside the groove in succession. An insulating layer 7, a P side electrode 8 and an N side electrode 9 are shaped. Accordingly, since the buried and grown active layer is curved near an end surface thereof and beams reflected by the end surface are reflected irregularly by the interface of the active layer and damped, a feedback ratio is lowered and non-oscillation emission stability is improved, thus enhancing temperature characteristics.
