Title: Gas inflow structure in oxygen sensor
Inventor: HAMAGUCHI SHIGEKI
IPC: G01N27/409
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent adhesion of catalyst components to a protection cover by providing a gas inflow guide projection part, etc., which forms a gas inflow guide path in a space toward an internal circumferential edge of the gas inflow hole of an outer cover, in the inner cover of the protection cover. SOLUTION: A protection cover 5 is provided with an inner cover 6 which forms an inner gas inflow chamber 8, by surrounding the tip part of a sensor device and an outer cover 7 which forms an outer gas inflow chamber 9, and a plurality of gas inflow ports 10, 11 are provided therein. When combustion gas flows in along the central line 11a of the gas inflow port 11 of the outer cover 7, a part of the combustion gas collides against a guide face 19 in the circumference of the top 18 of a gas inflow guide projection part, so that a flow along the guide face 19 is applied on the gas in a guide path 21. Therefore, the combustion gas flows smoothly in a gas inflow port 10 of the inner cover 6, through the gas inflow guide path 21.  Catalyst components hardly stick to respective surfaces of the circumferential wall 6a of the inner cover 6, corresponding to the gas inflow port 11 of the outer cover 7.

Abstract: PURPOSE:To improve the working rate of the installation, and to improve the yield of product, by shutting down the installation after threading an inexpensive warmer coil, and by connecting the warmer coil with a product strip before restarting the rolling process. CONSTITUTION:At continuously rolling a strip 2 with a tandem cold rolling apparatus A and a continuous annealing apparatus B, if either one of A or B is to be shut down, in such a case of interrupting the operation of the continuous rolling process because of a trouble in the apparatus B, for example, the strip 2 is cut by a shear 15 on the run-out side of the mill. Hereupon, the operation of the apparatus A is continued as usual. At the apparatus B, a warmer coil 17 is welded to the tail end of the strip 2 once cut in the said shutting down operation, and the warmer coil 17 is uncoiled from the warmer coil pay-off reel 16, and hereby, the strip 2 is subjected to a normal treatment in an annealing furnace 10. When the coil 17 runs out of the furnace 10, the apparatus B is stopped and is subjected to an inspection and maintenance works; thereby, when the operation of the apparatus B becomes restartable, the strip 2 is welded to the coil 17, and the continuous rolling process is restarted.

The slit 21 is placed at a distance L1 from the light source 3, and a distance between a point Q0 intersecting with a light beam 7 on the slit 21 and the center line 8 is X0 , while an angle between the center line 8 and the light beam 7 is θ. Then the slit 11 is placed at a distance L2 from the slit 21, while the slit 22 (22A, 22B) is placed at the distance L2 from the slit 11. Light-receiving elements 4A, 4B are fixed at a position of a distance X3 which is obtained as a function of a right-angled direction from the center line 8 on an optic path from the light source 3 and a refractive index of moving and fixed slit disks 1, 2.

Filed: 1984-06-20
Abstract: PURPOSE:To prevent an unnecessary tension from being applied to a tape under loading by providing main and auxiliary brakes for a supply reel base and providing another brake for a take-up reel base and operating these brakes individually with a common slider. CONSTITUTION:Since a take-up reel base 5 is rotated in the direction opposite to that of certain-speed feeding and fast forwarding by the driving force, with which an attaching base of inclined and vertical posts of a loading mechanism is moved in the loading direction, to feed out the tape, an unnecessary tension is not applied to the tape. A main brake 63 and an auxiliary brake 64 of a supply reel base 4 and a main brake 65 of the take-up reel base 5 are operated individually by a cam gear 20 and a common slider 62. Since the main brake 63 is released first and the auxiliary brake is released later, the reel base 4 is not stopped suddenly, and the unnecessary tension is not applied to the tape. Consequently, timings of individual operations are adjusted surely, and the tape and each member are not damaged, and the device is made small- sized because the common slider 62 is used to operate brakes.

Abstract: PURPOSE:To provide a constant spring force by providing a gap adjustment ring of a predetermined thickness in a spring force adjustment mechanism in a clutch means. CONSTITUTION:A gap adjustment ring 36 is removably fitted on the outer periphery of a threaded portion 12 of a circular fitting member 14, and a nut 10 is screwed on the threaded portion 12. As a result, the nut 10 urges the gap adjustment ring 36  in the axial direction until it is no longer turned. The nut 10 engages the other end  of a spring 18 and urges it to urge a clutch sleeve 16 against the clutch surface. At  the time when the nut 10 is being rotated, a ball 26 which is partly exposed within  the nut 10 is repeatedly engaged and disengaged with respect to a click groove 34 in  the fitting member 14. When the nut 10 is no longer rotated, the setting of the  optimum spring force value is completed in case when the corresponding specified  gap adjustment ring 36 is used. Thus, any one can easily and reliably set an accurate spring force value.

Title: Microcomputer
Inventor: KANAYAMA HIDEYO
IPC: G06F9/48
Filed: 1983-07-13
Abstract: PURPOSE:To ensure the effective processing to a state of emergence, etc. and to improve the general-purpose properties of a microcomputer, by providing an interruption control circuit and a bus open control circuit to suppress the bus opening function during the highest priority interruption processing. CONSTITUTION:When an interruption request signal 6 is supplied to an interruption control circuit 2, an open control signal 5 is set at a high level. While a bus open permission signal 8 delivered from a bus open control circuit 3 is kept at a low level and never opens a data bus. At the same time, the execution is retained for interruption processing until the execution is ended with an instruction of a CPU4. The interruption processing is started when the instruction under execution is ended, and the mode is reset to the previous processing when the interruption processing is over. At this time point, the signal 5 is set at a low level with the signal 8 set at a high level respectively. Thus the bus is opened. In such a way, the bus open request is suppressed during the processing of the highest priority. This realizes the high-speed processing and improves the general-purpose properties of a microcomputer.
