Title: Manufacture of rim for steering wheel
Inventor: YAMAMOTO SHOICHI
IPC: B62D1/04
Filed: 1989-02-07
Abstract: PURPOSE:To facilitate joining of a hollow member by a method wherein a socket is engaged externally of the outer periphery of the abut parts of rims formed with an annular hollow member to caulk the outer periphery of the socket. CONSTITUTION:A socket 2 the center in a longitudinal direction of which coincides with that of a hollow member is engaged externally of abut parts 1a of two ends of hollow members 1 each bent and formed in an arcuate shape. The outer periphery of the socket 2 is caulked to form press grooves 2a to join together the abut parts 1a. This method eliminates the need to weld and join together the abut parts 1a, and prevents the generation of rolling noise due to drop of a molten metal in the hollow during welding. Since the abut parts are joined together even when a gap is provided between the end surfaces, positioned facing each other, of the abut parts 1a, management of the length of the hollow member 1 is not effected so strictly, and a managing cost can be reduced. This method enables reduction of a cost of a rim manufactured by using the hollow members.

Title: Initializing equipment for terminal equipment of exchange
Inventor: HAGIWARA HIDEJI
IPC: G06F1/24
Filed: 1989-02-10
Abstract: PURPOSE:To attain the initializing of a processor of a terminal equipment even when a fault takes place in the processor by providing a terminal accommodating equipment having a synchronizing signal generating circuit and the terminal equipment having a synchronizing signal detection circuit. CONSTITUTION:A processor circuit 21 in a terminal accommodating equipment 20 monitors the operation of a processor circuit 34 in a terminal equipment 30 through the transmission reception of a control command sent periodically. Then when a fault of the circuit 34 is detected, the circuit 21 of the equipment 20 controls a synchronizing signal generating circuit 23 to stop the generation of the synchronizing signal. Thus, the bit pattern of a synchronizing signal sent to the equipment 30 via a multiplex signal line 40 changes from the bit pattern when the synchronizing signal is generated into the bit pattern during the stop of the synchronizing signal. As a result, a synchronizing signal detection circuit 35 in the terminal equipment 30 cannot detect the bit pattern while the synchronizing signal is generated, discriminates the occurrence of a fault and sends an initializing signal to the processor circuit 34 through an initializing signal line 38. Thus, even when a fault takes place in the circuit 34, the circuit 34 is initialized.

Abstract: PURPOSE:To facilitate varying the width of a laser beam application to an object to be worked arbitrarily only by changing a reflective mirror by a method wherein the reflective mirror is provided between an integration mirror and the object to be worked and in front of the focus of the integration mirror. CONSTITUTION:A laser beam 5 is successively reflected by reflective mirrors 3 and 4 and introduced to an integration mirror 1.

Title: Catalytic separation membrane, catalytic reaction method ahd production of compound
Inventor: YOSHIKAWA MASATO
IPC: B01J31/22
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To recover a homogeneous catalyst having high performance but difficult to be recovered by forming a membrane from an inorg. membrane through which the catalyst, part or all of which is dissolved in a liq., is not passed. SOLUTION: An inorg. membrane used for this catalytic separation membrane may be any inorg. membrane if a catalyst, part or all of which is dissolved in a liq., is not passed through the membrane. An org. membrane cannot be used because it has inferior resistance to org. compd. performance, is swollen with an org. solvent and also has inferior separation performance. Since the purpose is to separate the catalyst used for an org. reaction, the inorg. membrane excellent in org. chemical resistance and without being swollen with an org. solvent must be used. The catalyst separation mechanism may be based on either of a size, an affinity or an other method. Though the mechanism is not clear at this point of time, the separation is preferably carried out by the size.  The material of the inorg. membrane is not particularly limited if the catalyst can be separated but a molecular sieve membrane is preferably used.

Abstract: PURPOSE: To enable opening operation and closing operation of shutter to be correctly controlled by enabling the shutter open pulse signal to be annihilated through the production of the shutter close pulse signal.  
     CONSTITUTION: Capacitors C 1  and C 2  which will undergo release operation at the time of photographing are charged with constant current and following to this, a switch S is temporarily closed, by which a one-shot multivibrator circuit (OSM circuit) X 1  is set, then the large current by the charging charge of the capacitor C 1  is supplied to a coil L 1  and the shutter is opened. A flip-flop circuit X 2  is set by the level inversion of the OSM circuit X 1  and after the set second time of a variable resistance R 2  the output of an exposure time control circuit X 4  inverts, causing the large current of the capacitor C 2  to be supplied to the coil L 2  and the shutter to be closed. At this time, a transistor Q 1  is cut off and the coil L 1  is demagnetized, hence the shutter is correctly closed by the energizing operation of the coil L 2 .
