Title: Method for measuring effective radius of tire
Inventor: MURAKAMI MASAKI
IPC: G01B21/10
Filed: 1990-06-08
Abstract: PURPOSE:To enhance resolution so as to respond to intended allowable errors by setting intended divided frequency, and counting roller-rotation pulses during the rotations of a tire by the divided frequency. CONSTITUTION:Tire rotation pulses and roller rotation pulses are always detected in an input port 25 and a counter 26. As far as interruption is not applied on a CPU 12, the measuring operation of the effective radius of a tire is not started. The other processing of the CPU 21 is performed. An interrupting number (m) of tire-rotation pulses is initialized under the inhibiting state of interruption. An intended divided frequency M is set with a keyboard 24. Thereafter, when the inhibition of the interruption is released, interruption is applied by the tire-rotation pulses. A value N1 of the counter 26 is read with the first rise-up. The detection of the tire-rotation pulses is further continued. At the first time when the interruption number (m) reaches the preset number of the divided frequency M, the next counter value N2 is read, and the operation of the effective radius R of the tire is performed.

Title: Composite textile fabric
Inventor: DAGURASU RAMU
IPC: B32B5/26
Filed: 1992-05-20
Abstract: PURPOSE: To provide a coposite textile fabric for being able to move moisture away from the skin to outside of a garment. CONSTITUTION: The composite fabric includes a first fabric layer comprising either a polyester or nylon material, which is rendered hydrophilic, and a second fabric layer comprising at least 25 wt.% of a moisture absorbent material such as cotton. The first fabric layer and the second fabric layer are formed concurrently by knitting a plaited yarn construction. The second fabric layer is preferable to be treated with a polyurethane to promote resistance to pilling. The first and second fabric layers form an incline acting as a driving force inside the fabric for moving water via the fabric by evaporating water from the water absorbing layer surface into surrounding air. Thus, the composite textile fabric is able to move effectively and smoothly water away from the skin to the outside of the garment.

Title: Electronic image pickup back
Inventor: NISHIMURA AKIMASA
IPC: G03B17/56
Filed: 1991-06-24
Abstract: PURPOSE:To set a device to a silver salt camera main body to perform electronic photographing without requiring a correction photographing optical system or a correction finder optical system for electronic photographing by giving an image pickup face, whose size is approximately equal to the aperture size of the silver salt camera main body, to a photoelectric conversion image pickup element. CONSTITUTION:A reflection mirror which leads a luminous flux to a finder system is provided at the rear of a photographing optical system lens, and the reflection mirror is jumped up and the luminous flux from a photographic lens reaches an image pickup element 2 when a shutter is operated. The luminous flux from an object is reflected by the reflection mirror to form the image on a focusing screen. A photographer determines the composition while confirming the object image formed on the focusing screen through an eyepiece, a pentagonal prism, and a condenser lens. In this case, since the image confirmed by the finder is formed on the image pickup element 2 as it is because the size of the image pickup face of the image pickup element 2 is approximately equal to that of an aperture of a camera main body 4, the correction photographing optical system or the correction finder optical system is unnecessary.

Title: Motor-driven zoom camera
Inventor: KASHIWABARA TOSHIJI
IPC: G02B7/04
Filed: 1989-06-13
Abstract: PURPOSE:To improve operability by controlling the moving speed of a zoom lens so that it may be a previously set speed regardless of the state of the zoom lens or the state of power-supply voltage. CONSTITUTION:When the zoom lens ZL is moved by a motor 1, the moving speed thereof is detected by a lens movement detection means 2 to be compared with a reference moving speed previously set by a comparison means 4. When the current moving speed is varied in relation to the reference moving speed because of the change of the power-supply voltage, as the result of comparison, a control means 5 increases or decreases the reference period of a control area in a motor driving signal for controlling the supplied state of driving energy to the motor in accordance with the varied state. Therefore, the moving speed of the zoom lens ZL is controlled to be near the reference moving speed regardless of the variation of driving torque caused by the change of the power- supply voltage. Thus, the operability in an operation for setting a focal distance is improved.
