IPC: G06K7/10
Filed: 1990-07-25
Abstract: PURPOSE: To make this system compact and light in weight, and portable by converging light beams reflected from an encoding mark, and including corrector elements arranged in the surrounding of a spin axis so as to direct the light beams to the opposite direction to the encoding marks along the spin axis. CONSTITUTION: Light beams reflected from an encoding label are directed to an optical transceiver 42, converged by a photodetector 56 placed at an upstream spin axis 60, and converged by a condenser part 46 of an optical transceiver 42. The photodetector 56 is attached to a cover member 50 covering the opening of a scanning unit 20, and the amounts of the light beams projected to the photodetector 56 are controlled by a light receiving part 47 of the light condenser part 46 when the size of the light receiving part of the photodetector 56 and the distance of the bar code label from the scanning unit 20 are changed. Thus, this system can be made light in weight, compact, and portable.

Title: Insulation structure of end part
Inventor: MIYAO HIROSHI
IPC: H01F27/32
Filed: 1982-11-10
Abstract: PURPOSE:To improve withstanding voltage of insulation of end part, by a methed wherein surface of a shield ring is covered by synthetic paper crepe with relative dielectric constant being specified value or less thereby electric field in wedge-like oil gap is reduced or the wedge-like oil gap is eliminated. CONSTITUTION:Surface of a shield ring 2 at end of a winding 1 of an oil immersed transformer is covered by synthetic crepe paper 6 having relative dielectric constant of 2.8 or less. For example, the cover 6 at the lower shield ring 2 of the winding 1 is formed by FEP (fluorinated ethylene propylene) laminated paper in crepe. Relative dielectric constant of the FEP laminated paper is about 2.6 at oil immersed state, but if the FEP laminated paper is formed in crepe the end of the shield ring 2 produces swelled part and space factor of the paper is reduced thereby relative dielectric constant of the cover 6 is further reduced to about 2.4. Residual wedge-like oil gap 7 becomes very small and relative dielectric constant of the cover 6 adjacent the oil gap 7 is reduced thereby field concentration to the wedge-like oil gap 7 is reduced to about 16-23%.

Title: Apparatus for controlling inter-vehicle distance and recording medium
Inventor: TERAMURA EIJI
IPC: G08G1/16
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To avoiding abnormal approach and hunting of control and stably control the inter-vehicle distance by carrying out control adequate to practical driving. SOLUTION: This control apparatus can decrease the speed at adequate timing to the practical driving since whether an operation instruction (S230) to the deceleration means (OD cut) of the control of the inter-vehicle distance is carried out or not is judged (S220) based on an acceleration deviation ATdelt between a seeming acceleration and the actual acceleration. Moreover, different from the case of the operation instruction (S230) in the step S220, whether a cancel instruction (S260) to the deceleration means is carried out or not is judged based on only the acceleration deviation ATdelt and judged in the condition that the aiming acceleration ATmc is increased (S240), so that the step S230 is prevented from being carried out at too early timing because of abrupt unbalance of power immediately after the step S260 and hunting can be avoided.  Further, hunting in a steep slope is also prevented by steps S250, S270.

Title: Connecting part structure for suction pipe of vacuum cleaner
Inventor: ANDO JIRO
IPC: A47L9/24
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a connecting part structure for a suction pipe of a vacuum cleaner capable of lightly executing mutual sliding between an outer pipe and an inner pipe (an extending/contracting operation of the suction pipe), improving the abrasion resistance of a seal ring and reducing producing cost. SOLUTION: The seal ring 8 with plural press contact parts 50 along the axial direction of an inner pipe 3 is used instead of an O-ring. In addition, at the pipe 3, ring-formed recess parts 51 corresponding to the parts 50 are formed with respect to the fitting part of the ring 8. As a ring-formed deflection allowable time is formed between the rear surface of the ring 8 and the pipe 3 by these parts 51, a ring 8 deflect-deforms the parts 50 according to the direction and the size of a sliding load of the ring 8 to obtain a proper sealing effect. Thereby, rubber hardness is set to be high to improve abrasion resistance.

IPC: H02M3/07
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a generator-booster system which prevents the reduction of its boosting efficiency, when the generation voltage of a power supply is decreased. SOLUTION: A voltage-sensing circuit 105 is provided which senses a generation voltage Vp of a thermoelectric conversion element for outputting a sensed signal P3 and operates intermittently by an intermittent pulse signal P2 of an intermittent-pulse generating circuit 104 and a signal storing circuit 106, which stores therein the sensed signal P3 of the voltage-sensing circuit 105 during the stopping term of the operation of the circuit 105 for outputting the sensed signal P3 as a stored signal P4 to a voltage booster circuit 107. The boosting multiple of the circuit 107 is made variable, in response to the stored signal P4.  Thereby, since the output voltage of the circuit 107 can be boosted to its desired boosted voltage with an optimum boosting multiple, the reduction in the boosting efficiency of a generator-booster system can be prevented, when the generation voltage of the thermoelectric conversion element is varied.
