IPC: G02B7/08
Filed: 1985-10-30
Abstract: PURPOSE:To obtain a lens moving device characterized by high mechanical durability and precise detecting operation by forming a stopper mechanical part consisting of a stopper member fitted to a screw shaft and a projected member fitted to a lens frame. CONSTITUTION:The screw shaft 2 is rotated by a motor 9 to be a rotational driving source to move a lens frame body 4 having a screw hole to be screwed with the screw shaft 2 forward and backward in the optical axis direction. An electric contact point 13 projected so as to be almost rectangularly intersected with the screw shaft 2 is fitted to a proper position of the screw shaft 2 and a contact pin 18 is fitted to the frame body 4 so as to be opposed to the electric contact point 13. The relative position between the contact pin 18 and the electric contact point 13 is determined so that the pin 18 is abutted upon the contact point 13 like a switch when the frame body 4 is moved up to the end of a moving range to detect the position of the frame body 4. Stoppers 14, 16 are fitted to proper positions of the screw shaft 2 respectively corresponding to one outside and the other outside of the moving range of the frame body 4 and brought into contact with the projected member 19 formed on the frame body 4 to restrict the moving range of the frame body 4.

Title: Graphic contour line recognition method
Inventor: MIYAGISHI TATSUYA
IPC: G06T7/60
Filed: 1993-09-28
Abstract: PURPOSE:To easily recognize the contour of the graphic expressed by vector data by determining the angle formed by an already determined contour line element and plural contour line candidate elements having the endpoint which coincides with the element when plural contour line candidate elements exist. CONSTITUTION:One element on a graphic contour line, a straight line AB, for instance, is selected and this straight line AB is defined as a contour line heading element for tracing the graphic contour line. Next, the endpoint which is capable of tracing the graphic in a counterclockwise direction is defined as an endpoint j and the endpoint which is not capable of tracing the graphic is defined as an endpoint i of the both endpoints A and B. A contour line candidate element having a point which coincides with the endpoint j is searched in a figure. When the number of contour line candidate element is 0, it is defined as an error. When the number is 1, the element is defined as a contour line. When the number is more than two, the element which is already determined as the contour line is defined as a base line, the angle formed by the base line and each contour line candidate element in the counterclockwise direction is determine and the contour line candidate element having the smallest angle is determined as the contour line.

Title: Gas analyzer
Inventor: NAGAO TOSHIYA
IPC: G01N27/409
Filed: 1991-09-20
Abstract: PURPOSE:To prevent a drain from being discharged at a stretch and a sensor from being broken due to thermal shock at the time of a next calibration by providing a drain pot halfway in a calibration gas introduction pipe and a heater or drain port near the pot. CONSTITUTION:A drain D which is generated in a pipe 19 by a gas to be measured is put into a drain pocket case 22 along with a calibration gas. The drain D stays on a bottom surface of the drain pocket case 22 and only the calibration gas enters a pipe 19b and reaches a zirconia sensor 1, thus preventing the sensor 14 from being broken by the drain D. The drain D staying in the drain pot 21 can be evaporated by a heater pipe 20.

IPC: B21D53/30
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To manufacture a rim for an automobile wheel whose weight is reduced while its required strength is secured by rolling a drop part with higher pressure than the pressure for other parts in the first rolling process. SOLUTION: A cylindrical tube stock with each end part expanded is rolled by an upper roll 7a and a lower roll 7b in the first rolling process, the clearance t4 of a part X corresponding to a drop part is set to 75 to 95% of the thickness of the tube stock (the clearances L1, t2 and t3 of other parts are 100% of the thickness of the tube stock), and the part X is rolled with higher pressure than that for other parts to reduce the wall thickness and to perform the work hardening. In the second rolling process, approximately whole shape of the rim is rolled, and in the third rolling process, the final shape is rolled. Any clearance for the drop part is set to the same value as that in the first process. The strength to satisfy the standard value is obtained thereby, and a rim for an automobile wheel with improved hardness can be manufactured.

Title: Circuit breaker
Inventor: YAMAGUCHI NOBORU
IPC: H01H39/00
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To ensure break of a circuit in a short time and ensure break of a circuit in a short time in accordance with the temperature of a bus bar even if the break of a circuit is impossible due to the failure of a control part or the like. SOLUTION: If a control part is normal, when an ignition part 29 is ignited with an abnormality signal from the control part, heating agent 27 charged in a thermit case 26 is heated, a retainer 45 is fused by the heat, and a compression spring 39a is elongated to jump up the thermit case 26. Therefore, break of electric connections occurs between the thermit case 26 and each of a first bus bar 11a and a second bus bar 19a to ensure break of a circuit in a short time. If break of the circuit is impossible due to the failure of the control part, heat due to the temperature rise of the first bus bar 11a generated by an overcurrent is conducted via a heat conductive terminal 32 to an ignition terminal 30c and a resistor 30b to make igniter 30a ignited by the heat, ensuring break of the circuit in a short time.

Abstract: PURPOSE:To shorten the moving time of a medium and to reduce the rate of the occupancy of an accessor so as to efficiently use an integrated optical device by once moving a medium released from a utilization to a cell nearest to an optical disk drive set to a virtual drive. CONSTITUTION:This optical disk medium moving system is provided with an accessor control section 1 which sets the cell nearest an OD drive as a virtual drive and controls the movement of an optical disk medium between the cell and OD drive and between the OD drive and virtual drive, timer 2 which monitors the elapse of time after the optical disk medium is released from a used condition, driving information table 3, and medium information table 4. The section 1 acquires a releasing timer value from the table 3 and delivers the timer value to the timer 2 when the section 1 moves the medium to the virtual drive. In the case of receiving the releasing timer value, the timer 2 counts the time and informs the section 1 of the time-out of the timer 1 when the time-out occurs. The priority at every medium is set in accordance with their utilization frequency and the user sets the priority to the medium information table 4.

Title: Pressure switch
Inventor: HAGA KYOSUKE
IPC: F16K3/00
Filed: 1993-09-29
Abstract: PURPOSE:To prevent the resin from being ruptured or damaged by making the minimum diameter of a spacer which has a ring installed to a connector, and supports the connector via the resin, smaller than that of the ring and so on. CONSTITUTION:A connector ring 300 is installed on a connector 315, and the small diameter section T of a spacer 317 supporting the connector 315 via the resin acting as an electrical insulator is smaller than the outer diameter of the ring 300. The opening section of a switch housing 33 is squeezed into a diameter smaller than that of the ring 300, and the resin 316 and the spacer 317 are fixed onto the housing 33. By this constitution, pressure applied to the connector is prevented from being one-sided over the resin, pressure is applied to the whole of the resin via the ring, and moreover, since pressure is surely transmitted to the switch housing via the resin, the resin can thereby be prevented from being ruptured or damaged.
