Title: Protector against lack of phase
Inventor: KATOU EINOSUKE
IPC: H02P7/28
Filed: 1978-12-06
Abstract: PURPOSE: To surely open a circuit breaker and prevent the partical DC energization of a control transformer even if AC power lacks in a phase, by full-wave-rectifying the AC power at its three phases to produce power for operating a trip coil for the circuit breaker.  
     CONSTITUTION: A circuit breaker 52 is closed to energize the turn-on coil 88F of an electromagnetic contactor 88 to run a motor 5 for a cooling fan and a DC motor 3. When an abnormal phenomenon such as the vanishment of field, the abnormal temperature rise of a converter 2, the overloading of the motor 5 or the like takes place, the abnormal phenomenon is detected by a field relay 40, a temperature detector thermal relay 49 or the like to operate a trip instruction relay 86 to energize a trip coil 4. Power for operating the trip coil 4 is obtained by a full wave rectification circuit comprising diodes 10 of a converter 2 and diodes 11 for a surge absorber. As a result, the circuit breaker 52 can be surely opened even if AC power lacks of in a phase.

Title: Semiconductor device
Inventor: KONDO TOSHIHIKO
IPC: H01L27/112
Filed: 1990-06-08
Abstract: PURPOSE:To realize more compactness and higher speed operation by the means of constitution of the second opening formed over the first opening in the prescribed part of the first region (the 2nd conductive type) of the second conductive layer, and the third conductive layer with AL main component, which is formed over the second opening. CONSTITUTION:With a contact opening 109 as a base of one unit cell, it is decided by the data on a mask during forming process whether a contact opening is necessary or not. In other words, electrical sensing of whether a wiring layer 110 and a conductive layer 103 make continuity or not contributes to the judgement of data, thereby a cell becomes an exclusive read memory. At this time, even if the conductive layer 103 and the wiring layer 110 are simply connected at an opening 109, short circuit occurs between cells in the cell part formed in matrix condition. To avoid this, a polycrystalline silicon layer is installed beneath the opening, and P-N junction is made by there forming N-type impurity layer 106 and P-type impurity layer 107. In this way, short circuit can be avoided due to operation of rectification. As a result, the conductive layer 103 and the wiring layer 110 can be directly contacted and more compactness can be realized.

Title: Liquid crystal chopper for infrared rays
Inventor: TAKEUCHI KOSUKE
IPC: G02F1/1343
Filed: 1988-06-17
Abstract: PURPOSE:To improve the ON/OFF ratio and the infrared-ray transmittivity by providing a grating-like pattern whose opening ratio is about 3/4 on an electrode and providing two pieces of infrard-ray transmission plate by shifting its electrode positions by 1/2 pitch each. CONSTITUTION:Electrodes 33, 34 of infrared-ray transmission plates 31, 32 are provided as grating-like patterns whose opening ratio is about 3/4, and two pieces of infrared-ray transmission plates 31, 32 are placed by shifting its electrode position by 1/2 pitch each. In the case of applying a current to a liquid crystal cell in which the electrode is formed by such a pattern, a liquid crystal molecule is arranged and vibrated along a current passage, therefore, incident infrared rays are scattered and its transmission quantity is decreased. On the other hand, when no current is applied, the liquid crystal molecule is arranged in parallel, and the infrared rays transmit through a part in which no electrode is formed. In such a way, the ON/OFF ratio can be raised. Also, the current being sufficient for causing a DS mode can be supplied to a material whose infrared-ray transmittivity is high, therefore, with regard to the infrared- ray transmission quantity, a high modulation degree can be obtained.
