Title: Wafer periphery exposing method
Inventor: MIURA SHINETSU
IPC: H01L21/30
Filed: 1989-09-21
Abstract: PURPOSE:To improve exposure position precision by performing exposure while the shutter operation is controlled by the rotation angle of a rotary stage. CONSTITUTION:The photo current of a photodetector 62 which receices a light from a light emitting device 61 is amplified and then compared with a reference voltage by a comparator 82. The reference voltage thereof is previously set as the value of a photo current generated when a photo sensor 6 is so arranged that the optical axis H comes into contact with the periphery 1e. A position controlling mechanism 7 makes a sensor 6 retaining the photodetector 62 and the light emitting device 61 move rectilinearly toward the rotating center OT according to a signal from the comparator 82, and controls the sensor 6 so as to detect always the periphery 1e of a wafer 1. Position data of the sensor 6 are detected with a position detecting means 9 by utilizing a pulse counter used in a mechanism 7. The position data of the sensor 6 obtained by the means 9 and the rotation angle of the wafer 1 obtained by a rotation angle reading mechanism are stored in a storing means. The deviation amount between the center of the circumference of the wafer 1 and the center of rotation is obtained by calculation from the moving amount of a periphery detecting sensor, and exposure is performed while a correction angle is taken into account, thereby obtaining a highly precise exposure position.

Title: Muffler for internal combustion engine
Inventor: MATSUMOTO AKIO
IPC: F01N1/08
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To facilitate manufacture of a muffler at low-cost by plotting out a plurality of expansion rooms with buffle plates provided in a muffler main body and providing an exhaust gas leading out pipe to be put from the rearmost expansion room through the front buffle plate and an discharge pipe to be communicated with the exhaust gas leading out pipe. SOLUTION: Exhaust gas from the engine of a motorcycle is passed through an exhaust pipe 5 and exhausted from a muffler opening part 5a1 to a front expansion room S1, then introduced to a next stage expansion room (rearmost expansion room) S2 by a communicating pipe 14 and, during this period, expansion/compression is performed. Exhaust gas in the expansion room S2 is then passed through a tail pipe 15a penetrating front and rear buffle plates 12 and 13 and discharge through a discharge part 15b to the outside. Since this tail pipe 15a sufficiently uses the length of a muffler main body 11 in the longitudinal direction, a long route is secured. Further, since the discharge part 15b is formed in the lower side of the front end of the muffler, gas exhaustion is prevented from being conspicuous.

Abstract: PURPOSE: To detect a defective product correctly by providing a memory circuit for periodically sampling & holding the voltage at a P-N junction of a semiconductor device a plurality of times during an interval when a current sufficiently higher than a normal current is fed, and means for displaying the output from the memory means. CONSTITUTION: During an interval TS, a switch 5 is turned ON to feed a chip 1 with power thus heating the chip 1. During an interval TS, the switch 5 is turned OFF and during the turn OFF interval, a sampling switch 7 is turned ON to sample & hold the base-emitter voltage VBE of a transistor Q. Power supply and sampling of VBE are repeated alternately and the VBE is measured repeatedly for one chip 1. The sampled & held VBE is expressed in terms of temperature and presented on an oscilloscope 11. Since variation of voltage at a P-N junction (temperature at P-N junction) can be grasped when a semiconductor device is heating, detecting bonding of the semiconductor device can be detected correctly.

Filed: 1990-09-17
Abstract: PURPOSE:To reduce a load to be applied to a drive transistor by so switching the voltage of a power source to a state as to be supplied directly to the transistor or to a state as to be supplied to the transistor through a predetermined voltage drop, and varying a motor supply voltage in response to the variation in a load. CONSTITUTION:When a control signal S1 is an L level, the output of an inverter 32 is an H level, and hence a relay controller 31 is not turned ON, and a relay contact 37 is OFF. The output of fan inverter 33 is an L level. In this case, since a predetermined voltage clamped by a Zener diode 32 is supplied to the base of a transistor 36, the transistor 36 is turned ON, and a power source voltage of voltage drop by the transistor 36 is supplied to the transistor Q1 of a drive transistor 2. On the other hand, if the signal S1 is an H level, the output of the inverter 32 is the L level, and the contact 37 is ON. The transistor 36 is self-biased, and a voltage Vcc is supplied directly to the transistor Q1 of the transistor 2.

Title: Manufacture of multilayer heat exchanger
Inventor: HASEGAWA ETSUO
IPC: F25B40/00
Filed: 1994-10-11
Abstract: PURPOSE: To provide brazing satisfactory between the two heat-exchange parts in a refrigerant evaporator having a main heat-exchange part for the heat exchange between refrigerant and air and an auxiliary heat-exchange part for the refrigerant to refrigerant heat exchange. CONSTITUTION: An auxiliary heat-exchange part 8 and a win heat-exchange part 7 are integrally put together and held, the former above the latter and the latter under the former, by jigs A, B, C. As a result, in holes formed in the end plate positioned highest in the auxiliary heat-exchange part 8 pipe connectors 13 can be fitted and held under their own weight. Whereas, with no fins 11, the auxiliary heat-exchange part 8 has a large heat capacity and increase of its temperature is retarded as compared with the main heat-exchange part 7, the main heat-exchange part 7, positioned lower, enables heat to transfer through the vertical jigs C to carrier-holding shelves. On the other hand, the auxiliary heat-exchange part 8, positioned above, makes it difficult for heat to transfer to carrier-holding shelves. Therefore, the increase of temperature is leveled out between the two heat-exchange parts 7, 8 and brazing to integrate the whole can be provided satisfactorily.
