Title: Method and device for detecting position of mobile body
Inventor: OSAWA KAZUYUKI
IPC: G01D5/244
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a position detecting technology for a mobile body wherein, the position of a mobile body which is reciprocally moved at molding such as a mold of a clamping device or a screw of an injection device is detected at high precision in a molding device for a resin material. SOLUTION: An encoder which outputs a count signal each time a mobile body moves by a unit movement amount while outputs zero signal each time the mobile body passes reference points set at constant intervals in the moving direction of the mobile body, and an absolute position discriminating sensor for outputting different discrimination signals at each discrimination point each time the mobile body passes the discrimination points set between adjoining reference points, are used. The mobile body is moved in one direction from an arbitrary position to detect count signal, zero signal, and discrimination signal so that the absolute position of the reference point for which a zero signal is detected is calculated based on the discrimination signal, with the reference point used as reference for counting the count signal, thus the absolute position of the mobile body is calculated.

Title: Apparatus for opening/closing bottom valve of tank truck
Inventor: ITO FUMITAKA
IPC: F16K31/44
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To allow a bottom valve to be opened/closed with reduced errors in operation without a danger that workers are tripped by transmitting open/ close drive force applied to an upper tank control lever provided on an upper part of a tank via an open/close drive force transmission means which vertically passes through the tank to the bottom valve. SOLUTION: The apparatus 5 for opening/closing bottom valve comprises an upper tank control lever 501, an engaging part 502, a through rod 503, a link plate 504, a transmission member 505 and other members. To open the bottom valve, the upper tank control lever 501 is rotated clockwise. Since the through rod 503 for transmitting open/close drive force passes through a tank 1, only a part of the apparatus 5 is exposed in a limited range in the vicinity of the upper tank control lever 501 on an upper part of the tank 1, so that there is few protrusion or the like by which workers might be tripped. In addition, since the open/close drive force is transmitted by the through rod 503 which passes through the tank 1 from upper to lower parts with substantially the shortest distance, errors in operation can be reduced.

Title: Analog display type electric timepiece
Inventor: KITAMURA HIROSHI
IPC: G04C3/14
Filed: 1985-09-24
Abstract: PURPOSE:To provide an analog timepiece which is of a thin type and is easily visible by forming a tray part having a step to a minute wheel and disposing an hour dial having an hour hand to the tray part. CONSTITUTION:A minute hand is attached to a minute hand attaching surface 1c of the minute wheel 1 and the hour hand is attached to the hour scale attaching surface of the hour dial 2. The step is provided to the wheel 1 to form the tray part 1d. A minute gear part 1b is provided to the bottom of the tray part 1d. Said part is guided to the wheel 1 by a circumferential wall 18a of a plate 18 and is thus rotated. The jerking in the number face direction of the wheel 1 is determined by the main plate 18 and a setting wheel plate 22; therefore, the timepiece can be easily assembled even without the high skill such as for mounting the minute hand. Since the minute hand attaching surface 1c of the wheel 1 and the hour scale attaching surface of the dial 2 are constituted approximately flush with each other, the display is more easily visible. The dial 5 is fixed to the plate 18 on the outside of the wheel 1. The dial 5 is also constituted approximate flush with the surface 1c. The need for the minute hand and the hour hand is thus eliminated and the overlap of the hands and the dial is eliminated, by which the reduction in the thickness in the central part of the time piece is made possible.

Abstract: PROBLEM TO BE SOLVED: To eliminate necessity for an on-vehicle equipment controller with which communication is performed by utilizing an enciphering device, to consider the transfer of a cryptographic key or its contents by directly dispatching the cryptographic key to an encoder and a decoder. SOLUTION: An encoder 131 enciphers communication sentence sent from an on- vehicle equipment controller 14 and dispatches it to inter-road vehicle communication equipment 12 and a decoder 132 receives the enciphered communication sentence from the inter-road vehicle communication equipment 12, decodes that sentence and dispatches it to the on-vehicle equipment controller 14. Besides, the encoder 131 and the decoder 132 get the cryptographic key from a memory 133 for cryptographic key preservation. An identification controller 135 controls a switch 136 when starting inter-road vehicle communication and sends identification information as contents in a memory 134 for identification through the inter-road vehicle communication equipment 12 to road side equipment 2 without enciphering it.  From the sent identification information and contents in an identification information/cryptographic key correspondence table storage means 26, a cryptographic key retrieving device 25 retrieves the cryptographic key corresponding to the identification information and sets it to a road side enciphering device 23.

IPC: C25D17/06
Filed: 1988-08-26
Abstract: PURPOSE:To increase efficiency of a plating process by a method wherein a frame that has been brought with its posture horizontal is caused to rise by slope-provided rising rollers, plating is accomplished, and then the frame is returned to its horizontal posture by slope-provided tilting rollers. CONSTITUTION:At the entrance of a plating section in a pass line L, a horizontal roller 7 transporting a lead frame F as oriented horizontal, a rising roller 8 and a rising roller 9 with its slope a little steeper, and a conveying roller 10 to convey the lead frame F as oriented risen are provided. Accordingly, a frame Fa now horizontal develops next into a frame Fb and then a frame Fc, gradually more vertical, to be finally a frame Fd completely risen, which is led into the plating section for plating. After the plating process, the frame F recovers its original horizontal posture after being forwarded by tilting rollers each of which is inclined more than its predecessor, before it is carried away. In this way, with the flame F subjected to plating as risen, higher efficiency may be achieved in plating.
