IPC: G02F1/03
Filed: 1987-04-24
Abstract: PURPOSE:To decrease the voltage to be impressed to a medium for optical modulation and to widen applications of use by adopting the constitution in which incident light for image reading-out is passed plural times in the medium for optical modulation impressed with an external control signal. CONSTITUTION:A transparent electrode 2 is provided in BSO (Bi12SiO20) 1 and a voltage is impressed thereto to form the image information of an input signal to the voltage distribution corresponding to the intensity distribution thereof. The incident light 9 has the plane of polarization parallel with, for example, the plane of the figure. This light passes the BSO 1 from an aperture 4 via a polarizing splitter 8, arrives at a reflecting surface 6, is reflected by the surface 6 so as to be passed again through the BSO 1, is reflected in a reflecting part 5 and enters the BSO 1 again. The light is returned to the aperture 4 and is emitted therefrom after such passage is repeated plural times. Of the exit light, the light which is modulated by the BSO 1 and has the plane of polarization perpendicular to the plane of the figure is reflected by the splitter 8 and a desired light image 10 is obtd. The impressed voltage is decreased and the applications of use are widened by constituting the modulator in such a manner.

IPC: G11C15/00
Filed: 1988-04-25
Abstract: PURPOSE:To provide an MPU which operates at a high frequency with high- speed coincidence information by installing two ports to a memory cell itself and giving a comparing function to each port. CONSTITUTION:The 1st object data (MPU-side address information) to be compared are inputted through input terminals 24-26 and an input buffer 63 and, when the 1st object data to be compared coincide with the information of an associative storage cell 21, control signals inputted to (n) MOS transistors (Tr) 9 become 'H'. If the 1st common line 77 is previously held at 'H' by means of a MOS Tr 85 for precharging, the 1st common line 77 is discharged to 'L' and a result indicating that the compared result is noncoincident is obtained at a high speed through a sense amplifier 81, when the control signal inputted to one of Tr 9 of a circuit 21 connected with the 1st common line 77 is 'H'. A compared result can also be obtained at a high speed even in the opposite case. In connection with the 2nd object data (write address information to a main storage device), a compared result is similarly obtained at a high speed and its coincidence signal is obtained through the two ports at a high speed.

Title: Polarity discriminating system for telephone line
IPC: H04M1/00
Filed: 1992-03-27
Abstract: PURPOSE:To perform a normal operation even when polarity is set in the reverse direction by counting the number of times of occurrence of collision between an incoming call and an outgoing call when an outgoing operation is performed, and changing polarity data on memory judging that the polarity of a battery is set in the reverse direction when the prescribed number of times of collision is counted. CONSTITUTION:A main controller 6 is operated by reading out a program stored in a ROE 4, and detects whether or not a telephone set generates a DC loop via a line controller 3 by photocouplers 1, 2 when receiving an outgoing instruction from a terminal. When no DC loop is generated, the state of a current on the photocouplers 3d, 4e is collated with the polarity data in the memory 5 by closing contacts 1, 2, and it is discriminated whether the normal operation is being performed or the incoming call is received. The number of times of occurrence of the collision between the incoming call and the outgoing call is counted, and when it occurs for (n) times successively, it is judged that the polarity of the battery of the telephone line is reversed, then, the polarity data in the memory 5 is rewritten. Thereby, the normal operation can be performed even when the polarity is set in the reverse direction.

Abstract: PURPOSE:To enable prevention of oxidation of a probe card, prevention of temperature rise of DUT and removal of dust inside a wafer prober by providing a means to absorb from the outside, a means to shut a prober airtight from the air and filter to remove dust. CONSTITUTION:After a transparent case 5 is opened and a wafer is provided to a wafer loader part 3, the transparent case 5 is closed and the wafer prober is shut off from outside air. Then, nitrogen gas is fed forcibly inside the wafer prober by a compressor 6 and evacuated through a filter 7. In the state, it is brought into contact with a probe card 2 and various tests are made. Since nitrogen gas is always fed through the filter 7 during operation of the wafer prober, oxygen is removed and oxidation of the probe card 2 is prevented. Furthermore, heat generation of DUT is prevented due to effects of air cooling. Since gas flows inside the wafer prober, it is possible to discharge dust generated inside to the outside and to remove it by the filter 7.

Abstract: PROBLEM TO BE SOLVED: To constitute a switching power supply device having a standby output at low cost, by driving a switching circuit in proper frequency and intermittently supplying the primary winding of a converter transformer with an output from a rectifying smoothing circuit. SOLUTION: In this device, a commercial AC power supply E0 is full-wave rectified by a rectifier circuit D1 and smoothed by a capacitor C0, and converted into a DC E1, and a primary winding N1 for a converter transformer T1 is supplied intermittently with the DC E1 through a switching circuit consisting of transistors Q1, Q2 and a capacitor C1. A frequency control circuit 10 as a control circuit on-off drives the transistor Q1 and the transistor Q2 complementarily in sufficiently high proper frequency, and displays operation as a current resonance type switching regulator. Accordingly, a power switching element at high price for switching a large input current or main output current is unnecessitated, and cost can be reduced largely and the device can be miniaturized.
