Title: Control signal generating circuit of automatic equalizer
Inventor: MATSUURA TORU
IPC: H03H15/00
Filed: 1984-11-21
Abstract: PURPOSE:To realize circuit integration providing a rectangular wave generator and a means outputting a rectangular wave of the rectangular wave generator when outputs of two correlation detecting means are opposite in the polarity and outputting the said output of the said polarity when the polarity is the same to an adder means so as to operate all the circuits in a binary signal. CONSTITUTION:Input levels to input terminals INKP and INKQ are logical H and L, and when either input is logical H, an output of an output terminal OUT is a rectangular wave regardless of the level of the other input. When both the inputs are logical L, the output is logical L and when both the inputs are logical H, the output is logical H. That is, only when either input is logical H, the output is a rectangular wave regardless of the output of the adder circuit 10 is a binary value, the output of an integration device 18 with reset goes to H/2 with the input of the rectangular wave and when both the inputs are logical H, the output of the integration device 18 with reset goes to H. The waveform is an output waveform of a control signal generating circuit 34. Thus, the waveform entirely equal output waveform of the integration device in using a conventional resistor adding means is obtained.

Title: Substrate module
Inventor: MURAKAMI ITSUKOU
IPC: H05K1/18
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To reduce a required substrate area for resin seal by mounting a semiconductor package in a recess of a substrate, by forming a resin injection part continuously from the periphery of the recess, and by charging a resin in the recess through the resin injection parts. SOLUTION: For mounting a semiconductor package 2 on a substrate 1, electrodes of the package 2 and pads 4 at the bottom face of a recess 12 are electrically connected through solder pads 3 to mount the package 2 on the substrate 1. An epoxy resin 6, etc., is injected and charged in the recess 12 through a resin injection part 9 to seal connections of the substrate 1 and package 2, using an adequate dispenser. Thus it is possible to reduce required substrate area for resin real, compared with that using a dam frame.

Title: Semiconductor integrated circuit
Inventor: NAKAMURA KYOTARO
IPC: H03L1/00
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor IC(integrated circuit) which can perform a stable operation against the rise of temperature and the drop of power supply voltage. SOLUTION: A delayed clock signal DCK which passed through a delay circuit 11 is held by a clock signal CK that is directly given and the timing comparison is carried out between both clock signals at an FF 12 of a detection circuit 10. If the delay time of the signal DCK exceeds a prescribed time due to the rise of temperature or the drop of power supply voltage, a detection signal DET is outputted. Thus, a selector 22 switches the clock signal CLK given to an internal circuit 30 to a clock signal CKb that is divided by a frequency divider 21. As a result, the heat generation of the circuit 30 is suppressed to drop the temperature against the rise of temperature. Then a stable operation is possible for a semiconductor IC owing to its slow operation when the power supply voltage drops.

Bits 21 consisting of the pigment layers 23a are recorded if the particles 12 are thermally decomposed by irradiation of the laser light 22 from the substrate 11 side. The bits having the distinct outer contour shapes are formed by the specific grain size of the particles 12 at this time and the fluctuation in the refractive index is decreased and the irregular reflections are decreased by the difference in the refractive index from the circumferential member. The deterioration by thermal disturbance is lessened as the layers consisting of the particles 12 are independent. The optical recording medium which has the high C/N and the enhanced recoding life and economy is obtd. in this way.

Title: Variable reactance element and phase shift circuit using the same
Inventor: OHIRA TAKASHI
IPC: H03H5/02
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To provide an infinite reactance change amount against the finite variable range of capacitance or inductance by parallelly connecting a first serial resonance circuit, for which a first inductance element and a first capacitance element are serially connected and either or both elements are variable, with a second serial resonance circuit connected in the same configuration. SOLUTION: When capacitance Cv is changed at a circuit for which the first and second serial resonance circuits (variable capacitors 1a and 1b and inductances L1 and L2) are parallelly connected, reactance X becomes '0' on the condition of Cv=1/ω<2> L1, 1/ω<2> L2 and susceptance B has a polarity. In this case, ω is an angular frequency. When the capacitance change range of variable capacitors 1a and 1b is Cmin<=Cv<=Cmax and the L1 and L2 are decided so as to satisfy Cmax=1/ω<2> L1 and Cmin=1/ω<2> L2, by changing Cv within the range from Cmin to Cmax, the reactance X can be changed from '0' to +∞ and from -∞ to '0' and the susceptance B can be changed from -∞to +∞. Thus, they can be changed in the infinite range.

Abstract: PURPOSE:To prevent variation in the efficiency of coupling with an optical fiber by returning one-order diffracted light to an acoustooptic element in parallel to said one-order diffracted light by a reflecting mirror which has two reflecting surfaces crossing each other at right angles, and guiding the diffracted light to one terminal of an optical fiber. CONSTITUTION:The one-order diffracted light 121 diffracted by the acoustooptic element 3 is reflected by two mutually orthogonal reflecting surfaces 18a and 18b of the reflecting mirror 18 to return the element 3 and then separated into zero-order diffracted light 1210 and the 2nd one-order diffracted light 1211. The diffracted light 1211 is diffracted at the same angle theta1 of diffraction with the one-order diffracted light 121, so the 2nd one-order diffracted light 1211 is projected in parallel to the incident light 12 from the element 3. Even if the angle theta1 of diffraction varies to theta2, the 1st diffracted light beams 121 and 121' and held parallel to each other and enters a condenser 5 to hold the coupling efficiency of light in the optical fiber constant. Consequently, electromagnetic shield structure is simplified and reduced in size, so it is manufactured at low cost.
