Title: Ball collector for device of automatically washing sampling piping
Inventor: NISHINO SHIGEO
IPC: G01N1/00
Filed: 1982-07-15
Abstract: PURPOSE:To prevent continuous measurement of sample water, even when sponge balls are collected in a ball collector, by protruding the outlet pipe of the sample water into a vessel, and providing the outer circumference of the pipe with plural holes. CONSTITUTION:The outlet pipe 20 of sample water is protruded into the vessel 18 of the ball collector so as not to disturb free movement of the sponge balls 24, and the total sectional areas of the holes 26 are formed larger than the sectional area of the inlet pipe 19 of the sample water, and that of each hole is formed smaller than that of the ball 24. If the device for automatically washing the sampling piping is misoperated, the balls 24 are collected in the vessel 18, and they never flow through the pipe 20 to invade into a water analyzer side. Since the sample water flows through the holes 26, the water can be measured continuously without stopping its feed into the analyzer or decreasing an amt. of feed, or causing the like problem.

Abstract: PURPOSE:To control one communication line in a central control unit so as to relay by arranging a signal relay device which receives information in a character-string from the central control unit through one communication line and transmits the information to the device to be controlled through plural communication lines between a central processing unit and the device to be controlled. CONSTITUTION:A central control unit 1 operates in order to transmit the control information for lighting and lighting-out of lamps A1, A2 and A3 corresponding to the respective circumstances about normality of devices to be tested 4a, 4b and 4c to a communication line L0. The devices 4a, 4b and 4c are connected to the unit 1. And the unit 1 regularly checks the normality of these devices, collects the normal/abnormal data and prepares the data for transmission, and transmits the data for transmission to the communication line L0. At this time a signal relay device 3 CD ON/OFF controls the communication line by being connected with the unit 1 through L0 and connected with an external device 2 through lines L1, L2 and L3. In the device 3 the received data is disused when a horizontal redundancy check is abnormal and the communication line is CD ON/OFF controlled when it is normal.

Abstract: PURPOSE:To prevent a burr phenomenon of an edge part, and to exactly clean a rotary body, by placing the edge part of an elastic member press-contacting with the rotary body in the lengthwise direction, in the opposite direction against the rotating direction. CONSTITUTION:When a photosensitive drum 16 rotates in the direction as indicated with an arrow (v), the drum 16 to which a residual toner is adhering reaches a blade cleaning device 17. An edge part 17c of an elastic member 17b is made to press-contact with the drum 16 so as to be in the opposite direction against the rotating direction, therefore, in the edge part 17c, not only friction force F but also reaction T are generated, and it is deformed so as to be drawn into the direction as indicated with an arrow by its resultant force P. The elastic member 17b is thin and contacts flatly with a supporting member 17a, therefore, a burr phenomenon is prevented, and the surface of the rotary body 16 is cleaned exactly.

Title: Brushless motor
Inventor: NIIKURA HIDEO
IPC: H02P6/14
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To suppress acoustic noises accompanying the phase switching and improve the efficiency by a method wherein the slant parts of the respective current-carrying waveforms of 1st - 3rd phases are made to cross the slant parts of the current-carrying waveforms of the other phases. SOLUTION: The respective phases of the detection signals of three Hall devices are different from each other by 120 deg. in terms of an electrical angle. If the maximum values of the signals (a) and (b*) are detected, a waveform shown by A is generated and, if the minimum values of the signals (a) and (b*) are detected, a waveform shown by B is generated. Further, the signal shown by A is shifted in an increasing direction and reversed to generate a waveform shown by C and the signal shown by B is shifted in a decreasing direction and reversed to generate a waveform shown by D. Those two waveforms are gated by switching pulses shown by E and F and the gated waveform signals are synthesized to form a first current-carrying waveform shown by G.  In the same way, the signals (b) and (c*) are synthesized to form a second current-carrying waveform and the signals (c) and (a*) are synthesized to form a third current-carrying waveform and those currents are supplied to stator coils as shown by H. As a result, acoustic noises accompanying the phase switching can be avoided and the efficiency can be improved.

Title: Gelatinizing propellant
Inventor: FUJIYOSHI HIRONOBU
IPC: F02K9/44
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To reduce a residual gel and improve the efficiency to supply a propellant by storing the gelatinizing propellant made by adding a polyacrylic acid to a hydrazine anhydride in a tank, to which a liquefacient made of a salt or alkali is mixed in for liquefaction before delivering thereof. SOLUTION: For delivering a gelatinizing propellant G used as a fuel of flying objects such as rockets, the gelatinizing propellant G is stored in a tank 2 first. Then 30 minutes, for instance, before delivery of a liquefacient made of a salt is supplied to the gelatinizing propellant G stored in the tank 2 from a liquefacient supply system 5. After the gelatinizing propellant G is liquefied, pressurized air is sent into the tank 2 from a pressurizing means 1, which sends out the liquefied propellant from a discharge port 2a via a propellant supplying pipe 3a to a propellant supplied system 3. This promotes fluidization inside the tank 2, reducing residual gel, while improving the delivery performance of the gelatinizing propellant G.

Title: Control method for tilt servo device
Inventor: KATAGIRI SHOICHI
IPC: G11B7/09
Filed: 1987-05-20
Abstract: PURPOSE:To reduce the crosstalk by effectively applying tilt servo in a video area. CONSTITUTION:In case of playing of a composite disk 1, absolute position information of a read-out area of the video area recorded in a read-in area is read, and a tilt servo device 7 is turned on when an information detection point reaches the video area at the time of playing the video area. The tilt servo device 7 is turned off based on the result of comparison between current position information of the information detection point obtained from read information and absolute position information of the read-out area. Consequently, tilt servo is applied to the video area throughout the servo effective range without adding hardware to a conventional player neither remodeling it. Thus, the residual error of tilt is reduced to reduce the crosstalk.
