Title: Transmission type liquid crystal display device
Inventor: TESHIROGI TOSHIYUKI
IPC: G09F9/00
Filed: 1986-06-03
Abstract: PURPOSE:To prevent a light beam form being leaked from a non-display segment, by placing an axis of polarization of a polarizing plate so as to be orthogonal, forming a black mask in a part except a display segment, and applying a voltage to only the non-display segment. CONSTITUTION:A display substrate 4 and an opposed substrate 6 are placed opposingly, and between them, a twist nematic type liquid crystal 7 is interposed. In a part except a display segment electrode 3 of the display substrate 4, a black mask 9 is formed. Polarizing plates 10, 11 are placed in the direction in which axes of polarization are roughly orthogonal. In this liquid crystal display device, as for a light beam of a light source 1, its polarization direction is prescribed through the polarizing plate 10, and its polarization direction is twisted about 90 deg. at the time of passing through a cell 2. Also, in a part to which a voltage of the cell 2 is not applied, the light beam transmits through the polarizing plate 11 as it is. On the other hand, in a part to which the voltage of the cell 2 is applied, a twisting effect is not generated at the time of passing through the cell 2, therefore, after having transmitted through the cell 2, the light beam cannot transmit through the polarizing plate 11. Accordingly, it does not occur that a light beam is leaked from a non-display segment.

Title: Buried semiconductor laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/227
Filed: 1981-08-18
Abstract: PURPOSE:To obtain a buried semiconductor laser capable of operating at high power and high temperature with extremely small leakage current by forming the first conductive type semiconductor layer having a forbidden band width smaller than that of a current block layer on a semiconductor substrate. CONSTITUTION:A buffer layer 31, an N type InGaAsP layer 32, a lower clad layer 33, an active layer 34, an upper clad layer 35 and a cap layer 36 are formed by liqid phase epitaxial technique or the like on an N type InP substrate 30. Then, the layers 36, 35, 34, 33 are striped by photoetching with an SiO2 film as a mask. Thereafter, a current block layer 37, a buried layer 38, N type InGaAsP layer 39 are formed again by liquid phase epitaxial technique. Since the layer 32 has a forbidden band width narrower than the current block P type layer (rho-InP)37 corresponding to the base, the gain of an N-P-N transistor 44 becomes small, thereby enabling to set the leakage current IL substantially to zero.

Title: Aerobic self-granulated material and production thereof
Inventor: NAKANO SHIGEKAZU
IPC: C02F3/10
Filed: 1991-05-31
Abstract: PURPOSE:To obtain a self-granulated material high in organic matter decomposi tion performance by entangling protozoa with aerobic filamentous bacteria and granulating them. CONSTITUTION:Self-granulated material 31 is formed by entangling filamentous bacteria 32 and protozoa 33 are incorporated therein. Since the whole body is microorganisms, organismic reactivity is superior in comparison with a mixture formed by a carrier bonding method and an microorganismic capsule produced by a comprehensive immobilization method. Further since this self- granulated material is formed of aerobic filamentous bacteria 32 and protozoa 32, organic matter decomposition performance is higher than the self-granulated material formed of the conventional anaerobic filamentous bacteria. The self- granulated material is very effective in treatment of organic drainage.

Filed: 1979-10-05
Abstract: PURPOSE: To enable to exchange a pads promptly and with ease, by inserting a stopper member into a recess formed between a carrier and bridge port of a caliper turned around a pin.  
     CONSTITUTION: Recesses 10, 11 are formed respectively at the parts of the carrier 4 and the caliper 7 where the carrier 4 and the bridge part 7b of the caliper 7 are located adjacently to each other when the caliper 7 is turned around the pin 6 to a pad exchanging position in a direction opposite to that shown by arrow 9. By inserting the stopper member 12 to extend through the two recesses 10, 11 when the carrier 4 and caliper 7 are located in the above position, it is enabled to prevent the caliper 7 from turning in a reverse direction shown by the arrow 9 and thus to exchanged the pad with no hindrance of the caliper 7. Here, since the length L of recess 11 formed in the bridge part 7b is made larger than the width of stopper member 12 and slightly larger than the sum of maximum tolerable wears of the pad, adjustment of the position of bridge portion 7b in its axial direction can be avoided in inserting the stopper 12.
