Title: Heat-wave ultrasonic composite type burglar sensor
Inventor: TAKAGI TOSHIMASA
IPC: G01V1/00
Filed: 1989-05-25
Abstract: PURPOSE:To prevent an ultrasonic wave from turning into the inside of a cover housing by turning simultaneously an ultrasonic horn, as well by a connecting means, when a reflecting mirror is turned, and allowing the ultrasonic horn not to be inclined, when the reflecting mirror is inclined. CONSTITUTION:In the rotational direction of a reflecting mirror 2, an ultrasonic horn 5 rotates synchronously, but even if the reflecting mirror 2 is inclined in the direction being orthogonal to the rotational direction, namely, to the left and the right, the ultrasonic horn 5 is not inclined in the direction of the left and the right. Therefore, no gap is made between an opening part of the ultrasonic horn 5 and a cover housing 4. Accordingly, it can be eliminated that an ultrasonic wave generated from an ultrasonic vibrator 8 contained in the ultrasonic horn 5 turns into the inside of a sensor housing, and a beam of the ultrasonic wave being an object cannot be formed in the direction indicated by the reflecting mirror 2.

Title: Constant speed control device
Inventor: INOUE HITOSHI
IPC: F16H61/00
Filed: 1990-05-22
Abstract: PURPOSE:To enhance the feeling of running in the range of a highest limit vehicle speed during operation of an accelerator by restraining the upper limit of a desired vehicle speed upon acceleration up to a highest limit vehicle speed, and then by performing the control of constant speed running with an actual speed as a new desired vehicle speed which has been attained at the time of completion of the accelerator operation. CONSTITUTION:Each of control devices 1,6 is composed in general of a microcomputer. Of these control devices 1, 6, the speed change control device 6 computes a suitable position from the relationship between a vehicle speed and a throttle opening degree through a data map so as to control a transmission. This speed change control is independent from control of constant speed running, but an OD cut and a control right for recovery are sometimes given to a constant speed running control device 1 in dependence upon a system to be used. That is, the constant speed running control device 6 stores an actual vehicle speed in memory when a set switch 4 is manipulated, and thereafter, the constant speed running control is started. During this control, a signal is delivered to an actuator 2, a throttle 3 is regulated so as to hold the actual vehicle speed at the desired vehicle speed. Meanwhile, when an accelerator switch is manipulated during constant running speed, the desired vehicle speed is increased to increase the actual vehicle speed.

Title: Rear wheel driving mechanism of motor tricycle
Inventor: IGARASHI FUTANORI
IPC: B60K17/04
Filed: 1981-08-24
Abstract: PURPOSE:To enable to realize the large minimum under clearance of the motor tricycle by a structure wherein a final gear is made small by employing multi- step reduction between the output shaft of the engine-transmission assembly and the rear wheel shaft of the motor tricycle through a gear transmission means. CONSTITUTION:The rotation of the output shaft 30 of the engine-transmission asembly is lowered enough through an intermediate larger gear 36 and further through an intermediate smaller gear 38 and a rear wheel side gear 40. Because the reduction is made through the intermediate gears 36 and 38, the diameter of the rear wheel shaft gear 40 is made smaller as compared with the diameter of a sprocket wheel used in conventional chain-drive reduction system. As a result, a compact gear case 44 is realized and the larger minimum under clearance can be possible.

Abstract: PURPOSE:To make it possible to inspect complete entire outer surface in array probes wherein array piezoelectric transducers are arranged in a ring shape by inputting the output of a flip-flop circuit at a final stage of a shift register into the flip-flop circuit at the first stage. CONSTITUTION:Delayed pulses are applied to the specified continuing number of many array piezoelectric transducers in array probes which are arranged in a ring shape.
