Abstract: PURPOSE:To make the chip size of a semiconductor integrated circuit device small by forming epitaxial resistance and polysilicon resistance at a same region. CONSTITUTION:In a semiconductor integrated circuit device which is equipped with epitaxial resistance 1 that is formed by insulating discretely, at an insulating region 2 for isolating elements, an epitaxial layer formed on a semiconductor substrate; polysilicon resistance regions 4 that are formed on the preceeding epitaxial layer, it is constructed that respective polysilicon resistance regions are formed on the region of epitaxial resistance 1.

Title: Gravity filtration apparatus
Inventor: NAKADA KIMIMICHI
IPC: B01D29/88
Filed: 1987-12-14
Abstract: PURPOSE:To eliminate requirement for mechanically movable parts for balancing always the amt. of charged feed water and the amt. of discharged filtered water by communicating a pipe fixed at a neighborhood of the level of the feed water in a tank installed with a filter tank in its inside with a vent pipe, and providing a vent hole capable of increasing or decreasing the degree of opening of the hole depending on the vertical change of the feed water level. CONSTITUTION:When feed water level rises by the progress of blocking of a filter layer 8 to some extent, a sucked air amt.-control mechanism 20 is dipped in the feed water and an air sucking hole is closed partly by the water level, restricting thus the amt. of air supplied to the top 15 of a siphon tube through the vent pipe. Thus, the air pressure at the top 15 of the siphon tube is reduced to a negative pressure below the atmospheric pressure, increasing also the amt. of filtered water overflowing a weir part 15 of the siphon tube. This negative pressure exerts in the inside of a filtered water discharging pipe 2 as a negative resistance to the water passage for flowing the filtered water positively. When the blocking of the filter layer progresses further causing the rise of the feed water level, the degree of opening of the sucking hole of the mechanism 20 is restricted further, causing reduction of the air pressure to more negative pressure.

Filed: 1987-12-14
Abstract: PURPOSE:To prevent the improper assembly of a seesaw lever by forming projections at the stopper part for seesaw operation corresponding to each other in the rear part of the seesaw lever and inside a casing. CONSTITUTION:An approximately U-shaped movable armature 14 of spring characteristics retained with a common terminal 15 built into a box type casing 17 is reversed with the spring pressure thereof via the operation of a seesaw lever 13. And contact with an individual terminal 16 built into the casing 17 is changed over, thereby turning a switch on and off. A projection 13a is provided on the rear side of the seesaw lever 13, and another projection 17a inside the casing 17, thereby preventing the reversed ON/OF display of the seesaw lever 13 and reversed assembly thereof. Even if the seesaw lever 13 is reversely assembled, the projections 13a and 17a of the seesaw lever 13 and casing 17 contact with each other, thereby ensuring a construction to prevent the operation of the seesaw lever 13. According the aforesaid construction, it is possible to prevent the improper assembly of the seesaw lever 13.

Filed: 1989-12-05
Abstract: PURPOSE:To improve designing suitability by a method wherein the surface of a frame body is covered with a bendable deformable cover frame, and a covering sheet is mounted on the surface of the cover frame. CONSTITUTION:Rodform frame material with which a main frame 15 and a press frame 16 are respectively formed are molded through extrusion-molding, and cut surfaces are butted against each other for thermal fusion. A cover frame 24 is then molded through extrusion-molding. Covering sheets 25A and 25B are mounted on the surface of the cover frame as the cover frame is rolled in a flat manner by means of a roll R when it is still in a softened state before cooling. The covering frame is forced to pass through a mould again to mold it in a final shape. The surfaces of surface sheets 18A, 18B, and 18C of a frame body 12 are covered with the frame 24 to form a protrusion 27 thereon, which is securely locked in a groove 28. This method covers the cut mark of the protrusion part of the surface sheet 18A and causes butting of the sheets 24A and 24B against each other in a state to be positioned flush with each other, resulting in improvement of designing suitability.

Title: Method for measuring dc component of power cable
Inventor: SAWADA TOSHIYUKI
IPC: G01R27/18
Filed: 1987-12-16
Abstract: PURPOSE:To measure a DC component with good accuracy, by connecting the shield layer of a cable to be measured to the parallel circuit of an AC earthing condenser and a DC current measuring apparatus on the ground side thereof and connecting the shield layer of a cable being a non-measuring object to the neutral point of a GPT transformer. CONSTITUTION:The conductor 2 of a power cable 1 to be measured is connected to a high voltage bus 4 and an earthing type instrumental transformer GPT 5 is connected to the bus 4. Herein, the parallel circuit of an AC earthing condenser 6 and a DC current measuring apparatus 7 is connected between the neutral point of the GPT 5 and the ground, and the shield layer 3 of the cable 1 is connected to the parallel circuit on the ground side thereof by an electric wire 8 and, further, the shield layer of a cable 11 being a non-measuring object is connected to the neutral point of the GPT 5 by an electric wire 9. By this method, the current flowing between the conductor 2 and the shield layer 3 flows as shown by an arrow of an one-dot broken line and the DC current component thereof flows to the measuring apparatus 7 but the current flowing between the conductor 12 and shield layer 13 of the cable 11 flows as shown by an arrow of a dotted line but does not flow to the measuring apparatus 7. Therefore, only the DC component of the current flowing between the conductor 2 and the shield layer 3 can be accurately measured by the measuring apparatus 7.

IPC: G02B27/00
Filed: 1990-11-20
Abstract: PURPOSE:To maintain a satisfactory optical conjugate relation steadily by a method wherein one component of a light source means and a grating lens are held by holding members having different linear expansion coefficients and a relative distance between the light source means and the grating lens is changed in accordance with the wavelength fluctuation of a light beam emitted from the light source means which is caused by a temperature change. CONSTITUTION:One component of a light source means 101 and a grating lens 102 are held by holding members having different linear expansion coefficients and a relative distance between the light source means 101 and the grating lens 102 is changed in accordance with the wavelength fluctuation of a light beam emitted from the light source means 101 which is caused by a temperature change so as to maintain an optical conjugate relation. That is, the holding member 6 is cylindrical and has a linear expansion coefficient of alpha2 and the grating lens 102 is fitted to its inner wall. With this constitution, a change, for instance the longer a wavelength, the shorter a focal distance, which is characteristic of the grating lens can be corrected and a light beam in a proper state can be emitted steadily.

Title: Production of aluminum nitride powder
Inventor: MURASE MITSUTOSHI
IPC: C04B35/581
Filed: 1988-12-15
Abstract: PURPOSE:To obtain aluminum nitride powder giving a formed article having high density by carrying out reduction nitriding reaction of alumina, carbon and nitrogen in the presence of a specific amount of a Ca compound. CONSTITUTION:A powdery mixture of alumina and carbon is calcined in nitrogen atmosphere and the obtained carbon-containing AIN powder is calcined in an oxygen-containing atmosphere to remove excess carbon and obtain AIN powder. In the above reduction nitriding process, the reaction of the powdery mixture of alumina and carbon in nitrogen atmosphere is carried out in the presence of 0.1-2wt.% (in terms of CaO) of a Ca compound. when the amount of the Ca compound is less than the lower limit, the obtained AIN powder has poor effect of preventing the formation of agglomerate and a high forming density is hardly attainable. The content exceeding the upper limit is also undesirable since the evaporated Ca compound is considerably deposited in the furnace. The presence of the Ca compound may be achieved by attaching Ca to alumina or carbon or adding the Ca compound to the system.
