Title: Rotary anode for x-ray tube
Inventor: MATSUMOTO TOSHIO
IPC: H01J35/10
Filed: 1982-05-19
Abstract: PURPOSE:To prevent the abnormal vibration of a bearing and provide a rotary anode for an X-ray tube with a long rotary life span by supplying a slide section generated by the pre-pressurizing mechanism of the bearing, among a shaft, the bearing, and a pre-pressurizing collar with a lubricant always while the anode is being rotated. CONSTITUTION:A groove 11 is formed in the part of a support shaft 6 that corresponds to a bearing 5 and a pre-pressurizing collar 9 by the etching method and is press-coated with molybdenum disulfide 12. Since the surface of the groove 11 becomes uneven by etching, molybdenum disulfide 12 is prevented from easily falling and generates a small amount of fall by rotary vibration. Since the sliding of the support shaft 6, bearing 5, and pre-pressurizing collar 9 is smoothed by this fallen molybdenum disulfide 12, uniform pre-pressure is always obtained in the bearing 5, and smooth rotation is obtained without generating any abnormal vibration in the rotation of the bearing 5 and the like, a rotation life span can be extended.

Abstract: PURPOSE: To make methane fermentation efficiently by providing a base material guide in a unit fermenter at one end of seriate fermenters and providing a sludge discharging port in a unit fermenter at the other end and installing an inclined board for flowing down of the sludge.  
     CONSTITUTION: The base material of dissolved organic matters is first led to the first fermenter 1 and generates methane gas by methane fermentation due to methane bacilli in the fermenter 1. The base material changed to sludge is led to succeeding fermenters 1', 1" successively by an inclined board 5 for flowing down of  the sludge, and similarly generates methane gas by methane fermentation caused by  methane bacilli. Since quick flow of the sludge is prevented by plates 6, 6' forming  a zigzag flow passage, fermentation is effected efficiently. The sludge becomes  digested sludge in the last stage fermenter 1" and discharged. The scum generated  on the surface of the liquid moves through a scum drift check plates 7, 7' and can  be utilized effectively for methane fermentation.

Title: Torque detecting device
Inventor: KANEKO TAKANOBU
IPC: G01L3/10
Filed: 1983-05-13
Abstract: PURPOSE:To make it possible to detect small torque highly accurately and to provide strength against large torque, by providing a tubular body, which is linked by a coupling structure that is provided with play and engaged and comprises a magnetic body that is fixed to both shafts; and covering the outer surface of the coupling part of a shaft to be measured. CONSTITUTION:Torque is applied to a shaft 10 to be measured. When the torque is relatively small, twisting moment acts on a tubular body 15 and a small diameter part 16b of a torsion bar 16, because engaging pawls 13 and 14 of two shafts 11 and 12 have plays. At this time, the twisting strength of said tubular body 15 and the small diameter part 16a of the torsion bar 16 are low. Therefore, the twisting amount is largely fluctuated with respect to the minute torque fluctuation, and the magnetostriction quantity yielded in the tubular body 15 is largely fluctuated. When relatively large torque is applied, the twisting moment also acts on the shafts 11 and 12, and the fluctuating rate of the twisting quantity of the tubular body 15 with respect to the fluctuation quantity becomes small.

Title: Device for driving brushless motor
Inventor: IZAWA YUICHI
IPC: H02P6/18
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To appropriately start a motor by composing the combination of stator coil winding to be energized first when the motor is started so that the combination can be changed each time when the motor is started. SOLUTION: The device gives a drive signal to a drive circuit so that stator coil winding to be energized is successively switched based on the position detection signal of a rotor obtained by detecting the change in an induced voltage from each motor terminal by a position detection circuit using a microprocessor. Then, when a brushless motor is to be started, the combination of the stator coil winding is stored in the microprocessor in advance as a conduction pattern for starting conduction from a conduction pattern 1, the conduction pattern is switched successively, and a rotor in halt state is rotated.  In this case, the conduction pattern to be energized first is changed each time when the motor is started from the conduction pattern 1 in the first start and from a conduction pattern 2 from the next start, thus preventing the same mistake from being repeated and appropriately starting the motor.

Title: Telephone receiver for glasses-type bone conduction hearing aid
Inventor: YAMADA YOSHINORI
IPC: G02C11/06
Filed: 1980-06-20
Abstract: PURPOSE:To realize a quick control and fixing of a hearing aid while a hard-of- hearing person wears the aid, by fixing a joint capable of controlling the angle of the vibration diaphragm to the ear adaptor with a hot-melt adhesive. CONSTITUTION:A control is carried out between a vibration diaphragm 23 and an ear adaptor 19 that conveys the vibration to a mastoid process centering on a resin heater 20 that serves both as a variable joint. When the control is over, the current is allowed to flow to the heater 20 from a conducting terminal 22 to generate heat. This heat dissolves a hot-melt adhesive 21, and the adhesive is cured by the natural cooling due to the discontinuation of electric conduction. Thus the ear adaptor 19, the heater 20 and the diaphragm 23 can be fixed with the prescribed relation of their positions. For the heater 20, a self-temperature control type heater that has no overheat beyond a certain temperature is used preferably since the resistance increases suddenly at a temperature higher than a certain level to give a limitation to the current.

Abstract: PURPOSE:To dissolve the ambiguity of parallel words by preferentially considering words registered as the same group by a user beforehand as the parallel words. CONSTITUTION:The words of the same groups registered by a same group management part 8 are stored in a same group word storage part 9 on a main memory 2. In the parallel clause ambiguity dissolving part of a language processing module 5, when the ambiguity of parallel clauses appears in a syntax analysis part, that is when plural pieces of solutions are obtained, a priority is given to a structure for which the words registered as the same group words are the parallel words so as to judge the priority of the solutions. Since the words registered in the same group word storage part 9 are registered as the words to be judged as parallel by the user, the expectation of the user is measured up. In a succeeding processing, only the solution which is given priority is used. Thus, the ambiguity of the parallel clauses is dissolved.
