Title: Switch control circuit
Inventor: HARAGUCHI MASATO
IPC: H03K17/26
Filed: 1986-09-11
Abstract: PURPOSE:To obtain a control circuit for an electronic switch with simple constitution ensuring the power-on reset of a control object circuit by using a control confirming signal representing the on-state of the control object circuit so as to control an off-signal only when the power supply of the control object rises completely. CONSTITUTION:When a voltage level transits from a low level to a high level at an on-signal input terminal 1, a high level is outputted at a control signal output terminal 3 and the control object circuit is turned on. Thus, the high level signal representing the on-state switching of the control object circuit is inputted to the control confirmation signal terminal 4, and then an output of an off-signal to the control confirmation signal terminal 4 is attained. Before the high level signal representing the power voltage of the control object circuit reaching a voltage VDD and the control object circuit to be switched is inputted to the control confirmation signal terminal 4, even if the voltage level transits from the low level to the high level at the off-signal input terminal 2, no low level is outputted to the output control signal output terminal 3.

Filed: 1986-09-11
Abstract: PURPOSE:To execute correction of tracking control, etc., by discriminating signals outputted from a photoelectronic element receiving a branched beam of light preceding a branched beam of light for controlling, and thereby transmitting an index signal indicating a damage in a disk. CONSTITUTION:In association with the rotation of the disk, a 2nd order diffracted light L2' passes through a damaged part 26 following the preceding diffracted lights L2, L1, L0, and L1' and then the light L2' is totally reflected by the disk, the output of the photosensor 13b is inverted from L-level to H- level. Simultaneously, a trigger pulse showing the rise of a signal is impressed to reset. If the flip-flop 22 is thus reset, the output of it inverts to L-level, and a switch 15 is closed. Consequently, a tracking error signal TR is impressed to a pickup driving circuit 16, and the control returns to the normal tracking control.

Abstract: PURPOSE:To maintain an artificial skiing slope by a method in which a high water absorptive resin granule is frozen to form an artificial granular snow and a fine artificial snow, and the fine artificial snow is placed on the artificial granule snow. CONSTITUTION:A high water absorptive resin granule absorbing 5-100 times water is mixed with liquefied carbonic acid and frozen to form a fine artificial snow, and the high water absorptive resin granule is frozen to form an artificial granule snow.

IPC: H03F1/08
Filed: 1989-08-23
Abstract: PURPOSE: To improve a step function response at an output terminal and the steepness of a step signal by using a 1st field-effect transistor(TR) to configure a reactance circuit with an inductive characteristic and placing the circuit in parallel with a parasitic gate-source capacitance of a 2nd field effect TR of a same conduction type as that of the 1st field effect TR. CONSTITUTION: A resistor R integrated in a substrate is placed between gate electrodes of MOS TRs T1 , T2 . TRs Q1 , Q2 are alternately turned on/off by applying a step function signal to a 1st input terminal 3 and a 2nd input terminal 4 with an inverted phase as a digital square wave signal. The resistor R and a capacitor C configure a phase shift circuit network, a gate voltage of the MOS TR T1 is used to delay a drain voltage when the TR is turned on or off at its drain electrode depending on values of a resistor R and a capacitor C. Thus, the inductive element is placed in parallel with a gate electrode of the 2nd MOS TR T2 . Thus, an output signal on the drain electrode has a comparatively steep edge.

IPC: H01L23/12
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of electromagnetic noise emanated from a semiconductor element, etc., to the outside of a semiconductor device by covering the semiconductor element and its periphery with shielding members made of a conductive material. SOLUTION: An annular ground pattern 14 is formed so as to surround the periphery of a rectangular semiconductor element 7a mounted over the surface of a substrate. Respectively opposing sides of the pattern 14 are coupled by shielding members 15 of metallic wires made of a conductive material in a lattice form to cover the element 7a. The members 15 play the role of a shield for preventing the leakage of electromagnetic noise. Additionally, due to their connection with the pattern 14, the members 15 let noise captured to thereby escape to the pattern 14. Furthermore, the members 15 can dissipate satisfactorily the heat produced by the element 7a to the substrate, since this contributes to improving the heat radiation of the semiconductor device.
