Title: Differential circuit for compound semiconductor integrated circuit
Inventor: RAI YASUHIKO
IPC: H03K19/0185
Filed: 1990-09-17
Abstract: PURPOSE:To stably drive the BFL inverter of the next stage of a differential circuit part by connecting a DFET whose drain is connected to power supply VSS and whose gate and source are connected in common between the complementary terminals of the differential circuit in an ECL input circuit. CONSTITUTION:When an input signal IN is level-shifted, and a Low level is inputted, a High level and the Low level are outputted to contacts N103 and N102 respectively by difference voltage from reference voltage VREF. At that time, the contact N102 of the Low side of the differential circuit of the differential circuit part 12 is clamped at supply voltage VSS by a current to flow in from the power supply VSS to the contact N102 through the DFET Q115, and the potential of the contact N103 of the High side is not raised by more than the Vf portion of the DFET Q114 from the contact N103 to the supply voltage VSS. The level of the output terminal N104 of the differential circuit 12 synchronizes with the level of the supply voltage VSS. Thus, the BFL inverter of the next stage of the differential circuit part 12 can stably be driven.

Title: Device for positioning table
Inventor: ARAKAWA KAZUHIRO
IPC: G12B5/00
Filed: 1994-09-14
Abstract: PURPOSE: To contrive stable accuracy for not producing an error even in the case of a long stroke by utilizing a laser beam as a reference line and detecting the displacements such as a straightness error and a yawing error. CONSTITUTION: Laser light 12a for emitting parallel with Y-axis is divided by a beam splitter into two pieces which are incident on light detectors 16, 17 respectively. The detectors 16, 17 are previously initially-regulated so as to output a signal of specified level in the state of an ideal Y-axis direction of a table 100, and receive incident light. The detectors detect the state displacement such as a straightness error and a yawing error and output photoelectric current corresponding to an incident position. A positioning control part 20 receives a directional signal or the like from a scale detector 74. The positioning control part 20 obtains a present position of the table 100 and drives a Y-axis drive means 84. In addition, the control part 20 receives analog signals of the detectors 16, 17, drives a straightness correction mechanism 94 and a θ correction mechanism 92, and corrects straightness and a θ-direction. Because an optical light beam is utilized as a reference line, stable accuracy can be obtained without receiving the restriction of any stroke and without any mechanical erroneous factor.

Title: Carrier plate
Inventor: WATANABE TADAO
IPC: H05K3/00
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent warpage from being caused by making a strain difficult to be accumulated even though a carrier plate is repetitively used by a method wherein a groove is provided along an edge of the carrier plate. SOLUTION: In manufacture of a laminate for printed wiring board, the laminate is manufactured by heating and pressurizing a charge plate 6 on a carrier plate 1 in a molding press. Though a groove 8 is provided along an edge of the carrier plate 1 at that time, a working position of the groove 8 is outside a part wherein the charge product 6 is placed. The carrier plate 1 receives repetitively heating, pressurizing, and cooling, a strain is accumulated following increase of the number of times for use, which appears as warpage, and shear is generated in the charge product 6 in carring and in insertion into the molding press. Then, when the groove 8 is worked on a periphery of the carrier plate 1, the strain in receiving repetitively heating, pressurizing, and cooling is released by the groove 8, and the strain can be minimized.  Since the warpage of the carrier plate is decreased thereby, the shear of the charge product 6 disappears. Then, a void of the laminate can be removed.

Title: Modulator
Inventor: MIYAMOTO TSUNEO
IPC: H04L27/12
Filed: 1983-12-30
Abstract: PURPOSE:To offer a modulator by means of the frequency shift keying system where the transmission bit rate is improved remarkably by synchronizing an integral number of times of a bit rate and a frequency shift with a phase locked loop. CONSTITUTION:A difference frequency signal output circuit 3 transmits a signal of 128kHz which is a difference frequency between output signals of a VCO1 and an oscillation circuit 2 and uses it as a 32kHz signal frequency-divided by a frequency divider circuit 4 and coincident with the bit rate of the transmission data. When the bit rate and the frequency deviation are synchronized, even if the two frequency signals generated from the VCO1 and the oscillation circuit 2 are selected in response to the transmission data C with a switch circuit 6 controlled by the transmission data C, the switching point to the two frequency signals is always the same. Thus, even if the modulation signal is applied at the reception side and compared with the reference value, the duty of the output signal is made constant at all times and stable.
