Title: Automatic focus adjusting device
Inventor: KIMURA KENJI
IPC: G03B3/00
Filed: 1985-05-17
Abstract: PURPOSE:To attain highly accurate automatic focus adjustment without delaying a response time by forming a light projecting means, a photodetecting means, a photodetecting signal forming means, a discriminating means, a variable time constant means, and an adjusting means. CONSTITUTION:An output of an oscillator 11 is amplified by a current amplifier 12 and infrared rays are emitted from an infrared ray emitting diode 13 by modulating the amplified signal at 5kHz to project the infrared rays to an object P. The reflected light generated by the object P is guided into the 1st 2nd photodetecting elements 21, 22 constituting a 2-divided photosensor and amplified by preamplifiers 31, 34, and then only the modulated components are extracted by BPFs 32, 35. A difference output is found out from the outputs of the BPFs 32, 35 by a subtractor 33 and held as a sample by a sample hole circuit 51. The sampling period is determined by an output pulse from a sampling pulse generator 53.

Title: Scintillation camera
Inventor: TAGUCHI MASATOSHI
IPC: G01T1/164
Filed: 1978-08-31
Abstract: PURPOSE: To accomplish efficient measurements by calculating and displaying at least one of the remaining items which are required for measurements of a preset  test piece and which are preset.  
     CONSTITUTION: Presettable items are preset by a preset swhich 6 as to three kinds of a measurement time T, a total counted value C and information density ID. The start of measurement is performed by setting an FF 13 in response to the signals of a measurement starting switch 14. Then, gate circuits G 1  to G 4  are turned off to feed UNBLANK signals to CRTs 5 and so onso that scintigram is displayed therein. At the same time, a counter 12 counts the signals of the items which are selected by a preset item selecting switch 8 and pass through the gates. On the other hand, a comparator 11 compares the value, which is set by the switch 6, with the counted value of a counter 12 thereby to reset the FF 13 when the two values are equal so that the display in the CRTs as well as the measurements are stopped. Thus, it is possible to efficiently accomplish the measurements.

IPC: F16D27/112
Filed: 1982-06-18
Abstract: PURPOSE:To prevent the fatigue breakdown of a spring due to an increase in the amount of flexure, by forming an elastic means of a configuration memory alloy in an apparatus wherein an armature is attracted against the elastic means such as the spring so as to be put in the state wherein a power is transmitted when an electromagnetic coil is excited. CONSTITUTION:When an electromagnetic coil 11 is excited, an armature 7 is attracted against a coil spring or a plurality of coned disc springs (hereinafter called springs) 8 by a magnetic path phi formed through a fixed core 15 to be connected to the fixed core 15, whereby the rotation of a driving shaft 2 is transmitted to a shaft 9 to be driven. The springs 8 are formed of a configuration memory alloy so as to have a flexure-load characteristic shown in the figure. By this constitution, a stress generated in the springs 8 when the amount of flexure thereof is increased with an increase in a gap 13 between the armature 7 and the fixed core 15 is suppressed to be nearly constant, and thereby the fatigue breakdown of the springs 8 can be prevented effectively.

Inventor: TERAJIMA TOSHIHIRO
IPC: H01R24/00
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To provide an electric connector capable of reducing its whole height and ensuring sufficient contact pressure between contacts. SOLUTION: A first contact 5 of a first connector 2 of this electric connector has a fork-like elastic piece part 30. By eliminating one piece of a conventional fork contact the height of the connector can be reduced. When an insertion protrusion 15 of a second connector 2 is inserted to an insertion space 14 of the first connector 2, the elastic repulsive force of the first contact 5 acting on a second contact 8 is received by a top plate 19 of a first housing 6 and a first metal shell 7 via the insertion protrusion 15. By preventing deformation of the insertion protrusion 15, sufficient contact pressure between the contacts 5, 8 is assured.

Abstract: PURPOSE: To ensure the error detection for the decoder with a small number of the elements by providing the decoder to decode the N-bit input signal, the parity check circuit and the circuit which selects one of the output signals of the decoder based on the input signal.  
     CONSTITUTION: The decimal number data to be decoded is given to decoder 100 via terminals A∼C as well as to signal selection circuit 102 in the form of selection designation input signal 201. The output of decoder 100 is applied to parity check circuit 101 as well as to circuit 102 in the form of signal 206 to be selected.

Title: Optical pickup device
Inventor: MIYAKE TAKAHIRO
IPC: G11B7/1359
Filed: 1990-04-20
Abstract: PURPOSE:To accurately and surely detect the focus error by constituting a device so that a division line in the direction parallel with the diffraction direction of a diffracting device is parallel with the minor axis direction of reflected light from a shaping optical device. CONSTITUTION:The laser light emitted from a semiconductor laser 11 as the light emitting device which emits light having an approximately elliptic intensity distribution is transmitted through a diffraction element 12 as the diffracting device and is converted to parallel rays by a collimator lens 13. Since the minor axis direction on the diffraction element 12 of reflected light from an optical disk 16 and the direction of a division line l1 coincide with each other, a focus error signal FES is scarecely affected even in the vicinity, where the beam of reflected light is approximately linear, on the element 12 as shown by a line P because of defocus due to astigmatism generated by a shaping prism 14 even if the division line l1 is slightly inclined or deviated. Zero-crossing does not occur in the focus error signal though the spot is linear.

CONSTITUTION:A light shielding member 15 is supported turnably at the approximate center on the front face of a camera 1 together with a reflecting mirror 16, and is turned by the operation of an operating member 14 for holding position, by which the mirror 16 is operated. The mirror 16 is in the inclined position where it inclines at about 45 deg. to the optical axis direction of a photographing lens L provided behind a window 8. Said mirror reflects the ray from an object in front of the camera 1 upward. On the other hand, while a holding member 21 is not operated by the member 15, the mirror 16 is in the vertical position where it is approximately perpendicular to the optical axis of the lens L, and the mirror reflects the ray from the object in front of the camera toward the object. The disposition and constitution of the mirror 16 which is in the vertical position in the stage of photographing with a self timer are so determined that the range of the object field photographed by the lens L is checked from the person in the object field.

Title: Heat fixing device
Inventor: IIZUKA TOUJI
IPC: G03G15/20
Filed: 1983-06-14
Abstract: PURPOSE:To shorten a preheating time by installing a plate type heating body which has length corresponding to the axial length of a fixation roll on the reverse surface of a guide member. CONSTITUTION:Heat rolls 1 and 2 use small-diameter, thin metallic hollow cores so as to decrease in thermal capacity. Further, the plate type heating body 12 which is nearly as long as the heat rolls is installed facing a paper feed guide 4. When a base 5 which holds a tone image 6 is conveyed as shown by arrow, the base moves along the paper feed guide 4 toward the press-contacting part of the heat rolls 1 and 2. At this time, the heating body 12 is supplied with electric power to heat the toner image 6 at temperatures above the softening point of the toner. Consequently, the toner image 6 enters a semifused state before fixation, so the image is fixed excellently with a short preheating time. Thus, the preheating time is shortened.

Abstract: PURPOSE:To enable wear powder to be discharged to the outside of a slide part and to prevent a steam regulating valve from being rendered ineffective, by a method wherein a spiral groove is provided in the inner surface of a bush. CONSTITUTION:The interior of a servo motor for a steam regulating valve is constituted such that, with a servo piston 3 moved upward, a coil spring 9 is compressed, and a rotation force is produced by dint of the spiral shape of the soil spring.
