Title: Bearing unit for motor
Inventor: YAMADA TOMIO
IPC: H02K5/24
Filed: 1990-11-27
Abstract: PURPOSE:To prevent a resilient shock absorber and a bearing from removing by disposing engaging parts, respectively, between a bearing base and the resilient shock absorber and between the resilient shock absorber and the bearing. CONSTITUTION:A resilient shock absorber is provided with a deformed part 20 which is produced by being pushed by a protrusion 19 protruding inward along the entire inner periphery of the opening of a bearing base 10, and the deformed part 20 engages with the outer peripheral edge of a bearing 9. The protrusion 19 of the bearing base 10 prevents removal of the resilient shock absorber 15 and the bearing 9 is prevented from removal by means of the deformed part 20. Since the engaging part between the bearing base and the resilient shock absorber prevents removal of the resilient shock absorber while an engaging part between the resilient shock absorber and the bearing prevents removal of the bearing, no special member is required for preventing removal. According to the constitution, vibration and noise can be suppressed easily without requiring special member.

Abstract: PURPOSE:To provide delicious tea at any time by disposing on the bottom portion of the hot water container of a tea strainer portion a heater for heating water, and detecting the temperature of hot water in the hot water container to control the heater. CONSTITUTION:A control portion 73 turns on or off electricity to be transmitted to a heater 20 disposed on the bottom portion of the hot water container 7 of a tea strainer portion and used for heating hot water in the hot water container 7. To make tea, a predetermined amount of water is stored in a water container 2 and tea leaves 14 are collected in a filter 9 and also the time t1 required for hot water in the water container 2 to be cooled by heat radiation and the time t2 during which the tea leaves remain in the hot water container 7 are set by the timer of the control portion 13 and then a tea server is started. When the time t1 for heat radiation elapses and hot water reaches a suitable temperature after water in the water container 2 is heated and boiled by a heater 3 a pump 4 is actuated so that the hot water in the water container 2 is fed into the hot water container 7 of the tea strainer portion. When a temperature sensor detects that the hot water temperature in the hot water container is less than a predetermined value transmission of electricity to the heater 20 is started so that the hot water container 7 is heated from its bottom portion. Therefore hot water in the hot water container 7 is always held at the most suitable temperature and the efficiency of extracting tea components is enhanced and so the tea becomes better.

Abstract: PURPOSE:To automatically prevent a car from succeedingly starting at once even if a preceding car gets starting, in the case where it is stopped in the forefront at an intersection and a railroad crossing, in a running controller for a vehicle running in the wake of the preceding car as controlling a throttle. CONSTITUTION:On the basis of each detecting signal out of a car speed sensor 10 and a car range sensor 12, an electronic control unit 14 calculates the objective driving force, feeding it to a driving force control means 20, through which succeeding travel in the wake of a preceding car is carried out. When a driver operates a brake pedal and a car speed canes down to zero, the electronic control unit 14 drives a brake hydraulic pressure holding means 22 and keeps a brake operating state on the basis of each signal out of a brake switch pedal 16 and a car speed sensor 10. Only at the time when a car distance with the preceding car is less than the specified value, and the preceding car is started and thereby its relative speed comes to positive, this keeping state is released, but such a case other than this, the brake keeping state is continued till the driver operates an accelerator pedal.

Filed: 1988-12-27
Abstract: PURPOSE:To improve reliability by deciding a fact that there is a defect in a body to be inspected, when the number of continuous detections of a reflecting signal in plural directions exceeds a threshold. CONSTITUTION:An ultrasonic probe 1 of a linear array type is controlled by a processing control part 3 and scans a body to be inspected 5 in the width direction W, moves by a prescribed distance in the lengthwise direction L, when a measurement of a 1-line portion is ended, repeats the scan and inspects the whole body to be inspected 5. In this case, each receiving element of the probe 1 outputs a reflected echo signal as a receiving signal, and comparing parts 7-1 to 7-n compare the receiving signals from each element with a level threshold which is set in advance by a threshold setting part 9 and decide whether a reflected echo exists or not, and output it to a parallel - serial converting part 11. Subsequently, the converting part 11 converts a result of comparison inputted in parallel to a serial signal and supplies it to a counter 13, and the counter 13 counts the reflected echo signal inputted as a time series and decides whether a defect exists or not. Also, counters 17-1 to 17-n count reflected echo signals supplied through shift registers 15-1 to 15-n and can decide whether a defect exists or not.
