Title: Production of gypsum from coke oven gas
Inventor: MIZUSAWA MASATOSHI
IPC: C01F11/46
Filed: 1990-02-23
Abstract: PURPOSE:To produce gypsum large in mean crystalline particle diameter by controlling the blowing amount of air into an oxidation tower so that the concn. of oxygen in gas discharged from the oxidation tower reaches the lowest value and pH of gypsum blurry is regulated to the value just before this pH is suddenly raised. CONSTITUTION:Coke oven gas is desulfurized and sulfur contained in the obtained waste liquid is burned. The combustion exhaust gas contg. SO2 is introduced into an absorption tower 1 and SO2 is absorbed into the prescribed amount of Ca(OH)2 soln. to produce hydrogen calcium sulfite slurry. This slurry is introduced into an oxidation tower 3 via a tank 2 and air is blown thereinto from the lower part. The slurry is oxidized to obtain gypsum slurry. Gypsum 6 is obtained via a thickner 4 and a separator 5. At this time, the blowing amount of air into an oxidation tower 3 is controlled at 1800-2500Nm<3>/H so that the concn. of oxygen in gas discharged from the oxidation tower 3 reaches the lowest value and pH of gypsum slurry is regulated to the value just before this pH is suddenly raised. Thereby gypsum 6 is obtained which has about 35-40mum mean particle diameter and is excellent in quality and high in commodity value.

Title: Synthetic resin bottle
Inventor: SHIMADA SHINJI
IPC: B65D1/18
Filed: 1996-03-01
Abstract: PURPOSE: To provide a synthetic resin bottle which has a high buckling strength and absorbs the evacuated pressure without spoiling the external appearance, for a technical subject that the vacuum pressure generated in the bottle is effectively absorbed in a state that a number of reinforcing grooves effective for increase of the buckling strength of a large biaxially oriented blow resin bottle molding are formed. CONSTITUTION: Flat walls 5 and a plurality of peripheral grooves 6 are parallelly provided at the body 2. The peripheral grooves 6 positioned on the flat walls 5 are made gradually shallower as they approach the central part. In this way, it becomes easy to be dented inward at a large curvature due to the vacuum pressure in the whole flat wall area having a large surface area and it becomes possible to absorb a large negative pressure with a little recessive deformation on the whole flat wall area. The material cost consumed for a bottle molding 1 can be remarkably reduced by increasing the mechanical strength in the structure.

Title: Field effect transistor and manufacture thereof
Inventor: ITOU TOMOHIRO
IPC: H01L21/338
Filed: 1983-03-17
Abstract: PURPOSE:To obtain an FET of high withstand voltage with good uniformity at a high yield by a method wherein a part of an operating layer between a gate electrode and a drain electrode is made of high resistant semiconductor, in a Schottky gate FET. CONSTITUTION:A high resistant semiconductor region 11 is provided on the surface side between the gate 3 and the drain 4 of the Schottky FET, and the thickness of the N-channel layer 2 under this region 11 is more reduced than thickness under the source 4 and the gate 3. In other words, by introducing the region 11, the device having a flat structure can exhibit the characteristic of a substantially recess structure, making the electric field between the gate and drain average and reducing the maximum electric field, resulting in the improvement of the dain withstand voltage. Unlike on the source side, electrons run in the neighborhood of a substrate interface on the drain side, therefore the deterioration of mutual conductances does not generate even when a high resistant region is provided on the surface side.

Title: Distribution system protective unit
Inventor: TSUKAMOTO JUNICHIRO
IPC: H02J13/00
Filed: 1990-02-26
Abstract: PURPOSE:To prevent interference by controlling the transmitting timing of data, to be outputted simultaneously onto a communication line from slave station units upon detection of a fault on a distribution line, with time delays different respectively from the zero cross point of an AC power supply. CONSTITUTION:Each slave station unit 7 transmits a section number in reverse direction from the ground fault direction, i.e., a section number for confirming an external fault, to relay units 9 and respective slave station units 7 through a communication line 8. Transmission timing of data is started at a zero cross point of an AC power supply with an inherent delay time being set in each slave station unit 7. Consequently, a transmitter 106 confirms that no other signal is transmitted on the communication line and then transmits the data.

Title: Ball shooting device for game machine
Inventor: AKASAKA MICHIHARU
IPC: A63F7/02
Filed: 1995-02-10
Abstract: PURPOSE: To shoot a game ball normally even when a return ball remains in a guide part by stopping the supply of the game ball when a residual ball is detected, simultaneously running idle a rotary arm and eliminating the residual ball from the guide part by the rotary arm. CONSTITUTION: A residual ball detection sensor 93 detects the residual ball in a guide passage 63, and a detection signal is inputted to a shoot control part 6A. The shoot control part 6A sends a command to a latching solenoid 85, and stops the supply of the next ball P2. Simultaneously, the rotary arm 65 is rotated by sending a command to a motor 68. Therefore, the rotary arm 65 runs idle without providing the ball to be shot, and abutted with only the residual ball remaining in the guide passage 63. In this way, the residual ball is shot advancing a game part or a foul port, and eliminated from the guide part. After the residual ball is eliminated, control is returned to ordinary shooting control. The elimination of the residual ball is performed by setting the rotating strength of the rotary arm 65 at a level over the required minimum rotating strength.

Title: Deformation measuring method for polygon mirror
Inventor: WAKASHIMA RIE
IPC: G02B26/12
Filed: 1990-02-28
Abstract: PURPOSE:To measure the distribution of the deformation quantity caused by centrifugal force by providing a disk-like projecting part on the upper face of a polygon mirror, allowing a light beam to be made incident on its peripheral edge corner part, rotating the mirror at a high speed and measuring the power of a reflected light. CONSTITUTION:On the upper face of a polygon mirror 1, a disk-like projecting part T which is scraped and formed at a sufficiently lower rotating speed than a speed at the time of measurement and whose peripheral edge is regarded as a true circle is formed. Subsequently, when the mirror 1 is rotated at a high speed and a light beam L1 is made incident at an angle on a corner part (t) of the peripheral edge of the projecting part T from a light source 2, a reflected light L2 of the light beam radiated to the upper face of the projecting part T is made incident on a sensor 3. In this case, the mirror 1 is deformed by centrifugal force caused by a high speed rotation and the light quantity of the reflected light L2 which is made incident on the sensor 3 is varied. Accordingly, by detecting this variation, a deformation distribution by centrifugal force of the mirror 1 can be measured and a shape variation can be conjectured.
