Patent JP-H11206700-A (JP)
Title: Endoscope
Inventor: ISHIBIKI YASUTA
IPC: A61B1/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To make a clearance between a fitting part of a member on a fixed shaft side, and an opening hole part uniform and very small, extending to the total periphery, and surely perform a sealing with a seal member by a method wherein by bringing an engaging part into contact with a contact part, the location of a member which passes through the opening hole part and is supported by a chassis, is restricted. SOLUTION: The positioning in the insertion part direction for a casing 4, a chassis 5, and a first fixed shaft 7, is not performed by the fitting between a fitting part 25 of the first fixed shaft 7 and the opening hole part 10 of the casing 4, but the positioning between the first fixed shaft 7 and the casing 4 is performed by bringing a contact part 28 on the first fixed shaft 7 side into contact with an engaging part 29 on the casing 4 side. For this reason, a clearance A between the outer periphery of the fitting part 25 and the inner periphery of the opening hole part 10 is set to be approx. uniform extending to the total periphery.  Therefore, an O ring which is located between the fitting part 25 of the first fixed shaft 7 and the opening hole part 10 of the casing 4 is prevented from abnormally deforming such as being crushed due to a shifting, and the sealing with the O ring becomes secure.

Abstract: PURPOSE: To facilitate assembly by bendingly forming a rod member so as to longitudinally arrange a fulcrum shaft part pivoted on a supporting member, an engaging recessed part, engaged with an engaging part in a clutch pedal, a contact part received and supported by a driving step, and an operation part manually operated. CONSTITUTION: In a holding metal fitting A, when actuating operation of a clutch pedal 19 is carried out, an operation part, 30D is oscillated upward around a fulcrum shaft part 30A, so that an engaging recessed part 30B is engaged with an engaging pin 19b in the clutch pedal 19. When actuating operation of the clutch pedal 19 is released with the engaging pin 19b engaged with the engaging recessed part 30B, the engaging recessed part 30B receives a contact pressure of the engaging pin 19b while preventing upward oscillation of the clutch pedal 19 by means of self-restoration force of the clutch pedal 19 to the side in which a main clutch actuating condition based on energizing force of a spring is accomplished, and downward oscillation due to self-weight of the holding metal fitting A is prevented, so that the engagement is maintained.  In this way, the holding metal fitting A which can be easily assembled is provided.

Title: Combustion apparatus
Inventor: WADA CHIYUUZOU
IPC: F23N5/22
Filed: 1981-02-05
Abstract: PURPOSE:To enable ignition at a combustor, of which safety factor is high, by deenergizing a solenoid which holds a wick, when a timer is set and operated, and energizing it again with a time lag, after a set operation is finished, in a kerosence combustor of the type of which wick is lifted up and down, having a timer mechanism with it. CONSTITUTION:A timer 34 is energized when a switch 23 is closed, when the contact 24 of a timer is closed to the side 33 of the timer. At this time, a point K is set to a designed potential, because a direct current voltage is generated between e-b points. A capacitor 37 starts its charging through diodes 35 and 36, and when a potential of the point q becomes higher than a point K after a set time, the output from a comparator 30 becomes high, too, and a solenoid coil 46(6) is energized. With such an arrangement, a lever 5 is attracted to a solenoid and a wick 2 is drawn up, ignited, and burnt. After combustion, when the time comes to set a timer 34, a solenoid coil 46(6) is deenergized, and a wick 2 is extinguished by depressing down.

Title: Soldering method
Inventor: MACHIDA KAZUMICHI
IPC: H01L21/60
Filed: 1981-02-06
Abstract: PURPOSE:To prevent the excessive melting of thin-films formed onto each member stably by shaping solder projections to the thin-films and preferentially heating only the noses of the projections when the each solder projection is contacted. CONSTITUTION:The solder projections 3a, 3b are formed previously to each of the first and second members to be joined 1a, 1b through the conductive thin- films 2a, 2b for shaping the projections. The solder projections 3a, 3b are contacted and reflowing-bonded, but respective solder projection 3a, 3b is heated so that the temperature of the nose sections is higher than the base sections and joined at that time. The heating method is that microwaves 5 are irradiated under a condition that there are comparatively much flux 4 at the contacting sections of several solder projection 3a, 3b. Accordingly, the flux 4 is heated preferentially because the dielectric loss to the microwaves 5 of the first and second members to be joined 1a, 1b, the thin-films 2a, 2b and the solder projections 3a, 3b is higher than that of the flux 4.

Filed: 1982-02-04
Abstract: PURPOSE:To shorten the time for filling a torque converter with oil by making a vacuum chamber of a vacuum control valve by-pass the air during a fixed period of time just after starting of an engine to raise line pressure. CONSTITUTION:If a shift is located in the area N or P at the time of starting an engine, an inhibiter switch 11 is on, and a timer 9 is started by turning on an ignition switch 12 to apply an urging signal to a solenoid coil 8a during a fixed set period of time, whereby a vacuum chamber 2a of a vacuum control valve 1 communicates with the air. In such a condition, the internal pressure of a line 4 is raised by driving a pump 5, which results in that oil filling in a  torque converter 7 progresses in a short time. After a fixed lapse of time, an  urging signal applied to the coil 8a is erased to cause the vacuum chamber 2a  to communicate with a suction pipe.

Title: Variable color discharge lamp lighting device
Inventor: TAKEUCHI HIROYASU
IPC: H05B41/36
Filed: 1990-01-26
Abstract: PURPOSE:To product a comfortable atmosphere having no sense of incompatibility by providing a control means for keeping the output of a fluorescent lamp nearly constant and varying only the color temperature of the fluorescent lamp. CONSTITUTION:A control means is formed of a volume Vr, an astable multibivrator 5, and a monomultibivrator 6. When the volume Vr for the time setting of the monostable multibivrator 6 is varied to increase that value, the duty ratio of the input signal to a lamp 1 having a high color temperature is increased to increase the output. As an output signal (b) is the reversal signal of a signal (a), the duty ratio is conversely reduced, and the output of a lamp 2 having a low color temperature is reduced. Thus, the whole color temperature is increased. The total output is nearly constant. When the value of the volume Vr is conversely reduced, the whole color temperature is reduced. The total output is constant. Hence, a comfortable light space having no sense of incompatibility can be produced.
