Title: Muffler for motorcycle
Inventor: TSUKIHANA RYOICHI
IPC: F01N1/10
Filed: 1992-06-08
Abstract: PURPOSE:To prevent the reduction of durability even in case of the use of catalysts. CONSTITUTION:The silencer inner edge part of a tubular member (rear part exhaust pipe 27d, exhaust lead-out pipe 29) inserted into a silencer 28 is supported by a supporting member. Each tubular member is press-fitted into the supporting hole of the supporting member (supporting plate 41, supporting pipes 45, 46) and joined. The front edge part 32a of an inner cylinder 32 is press-fitted into an outer cylinder 31 and joined. When each member in the silencer 28 is extended by the thermal expansion, the press fitting joint part shifts by the extension portion for the fixed side. Accordingly, the thermal stress acting on the member positioned in the silencer can be suppressed as small as possible.

Title: Drive circuit of spindle motor for driving disc type medium
Inventor: YAMAMOTO HIDEO
IPC: H02P3/10
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To stop rotation of a spindle motor without generating any noise immediately before stoppage by delivering a stop signal even under a state where a signal can not be read out from a disc. SOLUTION: Upon delivery of a stop signal, a SW2 is turned off and a rotational signal from a power amplifier (P-AMP) to a spindle motor M is interrupted. At the same time, a SW3 is turned on and a counter electromotive force induced in the motor M is passed through a counter electromotive force detection circuit (DET) and then sample geld, as the rotational information of the motor M, in a sample hold circuit (SP). Subsequently, a CONT (control circuit) calculates the level and the time of a reverse voltage for braking based on the voltage of the SP and commands a switch control (SWCNT) to deliver a corresponding voltage to the CONT (control circuit). At that time, the SW3 is turned off the SW2 is turned on and the SW1 is turned to side (b) and a brake stop signal is applied to the motor M, thus the motor M is stopped by applying brake.

Filed: 1981-10-28
Abstract: PURPOSE:To reduce a size of alignment mark area exceeding the specified limit by detecting at first the boundary between the alignment marks and then detecting only an effective alignment mark. CONSTITUTION:The CPU25 sets, first of all, a width m of prewindow signal S2 and a width c of window signal S3 to the counter circuits 22, 24 through the latch circuits 26, 27.

An output of detector in this period c is input to the counter circuit 31 through a gate 30 and positions of pulse signals are measured. The results are stored in the CPU25. When the CPU25 moves a wafer in the direction of X axis, only the mark signal including boundary of wafer moves. The wafer is then moved in the direction of Y axis and unmoved signal is considered as the bounary. The CPU25 sets the setting values of latches 26, 27 in order to detect only the effective alignment mark and carries out alignment.

Title: Testing device for dielectric breakdown strength
Inventor: YASHIKI KAZUMI
IPC: G01R31/12
Filed: 1989-07-03
Abstract: PURPOSE:To enable application of a high testing voltage by forming a recess matching a shape of an element to be tested on opposed surfaces of a carrier base and a keep plate to make a creeping distance larger along an insulated part between testing electrodes. CONSTITUTION:This tester is so arranged to be fitted into a recess 9a of a carrier base 2 with lead terminals 4a and 4b of an element 1 to be tested downward. Then, a high voltage is applied between the lead terminals 4a and 4b of the element 1 to be tested with a dielectric breakdown tester to perform a dielectric breakdown test. At this point, a creeping distance B between testing electrodes 5 is equivalent to a length along an outer circumferential surface between the lead terminals 4a and 4b of the element 1 to be tested. In this case, as the creeping distance is longer to the lead terminals 4a and 4b from a lower end rim as compare with the creeping distance in the past, the dielectric strength increases. This allows the application of a higher test voltage as compared with the conventional dielectric breakdown tester.

Abstract: PURPOSE:To make low-voltage control possible by a structure wherein relays equipped with contact in the hot water storage tank are shut-off from outside air with heat insulating material in order to prevent dew condensation. CONSTITUTION:Relays such as a temperature switch 3, a no-water relay 4 and the like are installed on the cover 5 of the upper opening of a water reservoir 6 and the heat insulating material 7 covers over the relays leak-tight in order to prevent the heat radiation.
