Title: Method and device for inspecting internal defect
Inventor: KOJIMA HIROSHI
IPC: G01N21/956
Filed: 1990-05-01
Abstract: PURPOSE:To non-destructively measure the distribution of an internal defect in the arbitrary direction in a measuring object by aligning automatically a focus of a microscope with a position on an optical path by interlocking with a movement of an incident position of a laser beam (LB). CONSTITUTION:An LB which holds the optical path direction prescribed by a prescribed incident angle is moved in parallel in the direction as indicated with an arrow 113 and changes successively incident positions Q1 - Qn, is subjected to total reflection in each position P1, and R2 - Rn of the upper face 112 of a measuring object 101, and allowed to pass successively through the positions P1 - Pn as indicated with arrows 114, 115. On the other hand, a focus of a microscope 102 is aligned with the positions P1 - Pn by interlocking with a movement of the LB, and in that case, an optical enlarged image obtained by the microscope 102 is converted to an electric signal by a detecting element 103 and outputted. In such a way, an electric signal for showing an image in a thickness direction (vertical direction) of the object 101 is obtained, and based thereon, an inspection of an internal defect is executed.

Title: Method for maintaining ferroelectric liquid crystal in transparent state
Inventor: YOSHINO KATSUMI
IPC: G02F1/133
Filed: 1984-05-31
Abstract: PURPOSE:To make a ferroelectric liquid crystal transparent and to improve the transmittance of light by impressing repeatedly a pulse voltage between electrodes sandwiching the liquid crystal. CONSTITUTION:The ferroelectric liquid crystal is a chiral smectic phase and is made into the helical structure in which the direction of the molecular long axis swings and rotates by each layer while maintaining the certain specified angle theta of inclination relative to the perpendicular to the smectic layer shown in figure (a). The state of figure (a) transfers to the state of figure (b) and all the directions of the dipole moments are unified to create the transparent state when the voltage is impressed thereto in such a state. The electric power loss occurring in ionic current increases when the DC is kept impressed and therefore the electric loss is decreased by increasing first the crest value or impression time of the impulsive voltage but decreasing gradually the pulse height or widening the pulse interval. The power loss is thus decreased and the transparent state is maintained while the deterioration of the liquid crystal is prevented.

Filed: 1987-05-07
Abstract: PURPOSE:To avoid the generation of a through current in a key input state by using a MOS gate to constitute a key input circuit which is needed for key scan of a key scanning circuit. CONSTITUTION:When a key 7 is turned off, an area is opened between an input/output terminal 55 of a column scanning circuit and a row scanning circuit 56. In a steady state, an input/output terminal 56 is set at a low level and the terminal 55 is always kept at a high level. The data fetched inside via a latch 3 has a high level; while the data fetched inside via a latch 6 has a low level. When the key 7 is turned on, a ratio circuit is formed with FET 1 and 4 and both terminals 55 and 56 are set repetitively at low and high levels. Then data are fetched inside at a low level via the latch 3 and at a high level via the latch 6 respectively. Thus the key input is carried out.

Filed: 1989-05-02
Abstract: PURPOSE: To provide an inexpensive and effective selection switch for stereo extension circuit by performing the cross coupling of a 2nd input terminal so as to supply extended stereo, when closing a switch means. CONSTITUTION: When stereo extension is not used, the output of a voltage responder 23 is low, and a transmission gate 21 is non-conductive. When stereo extension is used, the voltage responder 23 receives a positive input. When the transmission gate 21 is turned into a conductive state, negative input lines 17 and 20 of operational amplifiers 11 and 12 are coupled through a filter 22, the left and right channel signals are fed back by resistors 16 and 19 and due to differential cross-channel coupling, respective channel outputs affect the output of the other channels. Therefore, the output signal of the operational amplifier 11 becomes L+X(L-R), and the output signal of the operational amplifier 12 becomes R+X(R-L). Hence, a signal required for stereo extension can be provided by a simple circuit. In this case, the coefficient X is determined by the characteristics of the filter 22.
