Patent JP-H053656-A (JP)
Title: Power generation switch
Inventor: OKUI TAMIO
IPC: H02K35/02
Filed: 1991-06-20
Abstract: PURPOSE:To store generated energy in a built-in battery so as to continuously operate a power generation switch for a long time by means of the battery by inserting and extracting a rod-like permanent magnet which is interlocked with a push-button into and from a coil by pushing the push-button. CONSTITUTION:When a push-button 1 is pressed, a switch section 2 is actuated and, at the same time, a permanent magnet shaft 1 is inserted into and extracted from a power generation coil 3. As a result, electromotive forces are generated across both ends of the coil 3 by Fleming's rule. Since the polarity of the electromotive forces of a power generating section 3a to a battery 5 is alternately inverted when the button 1 is pressed and released, a rectifier (circuit 6 is required. Because of the operation of the button 1, the switch section 2 is used as a switch for another electric circuit. The operating work of portable OA equipment is mainly composed of keyboard operation and it is said that the operating frequency of keyboards reaches several hundreds to several thousands of times per hour. In addition, the battery 5 can also be charged when this power generation switch is connected to a keyboard.

Title: Apparatus for regulating generator
Inventor: BUARUTAA KOORU
IPC: H02J7/14
Filed: 1991-06-21
Abstract: PURPOSE: To enable it to be excited safely by laying the temperature of exciting winding within an allowable limit, in the case of using a generator intermittently under overexcitation. CONSTITUTION: The raised output power of a generator is obtained in the following way. That is, an excited current can be obtained by having a value above that of a nominally excited current, or by selecting the value so that the generator is heated under the most disadvantageous situation. To arrange it so that this does not occur even under the most disadvantageous condition, the temperature is measured with, for example, a measuring apparatus, and the temperatures of the dangerous places is computed taking into consideration typical parameters from these temperatures. When an unallowed high temperature is detected, the excitation current is reduced so that it may not go beyond a tolerable maximum temperature by a proper means.

Filed: 1986-06-25
Abstract: PURPOSE:To improve the productivity of an opposite type optical isolator by opposing a light emitting element and a photoreceptor rotated at 180 deg. via a hinge-pin as a shaft, and readily placing the element and the photoreceptor on a lead frame. CONSTITUTION:Tie rails of an LED 11 are cut from both sides of side rails 3, 5. Thus, the LED 11 becomes the state mounted only at hinges 31, 33 disposed laterally to be rotatable laterally with the hinge pin as a shaft. Since the dam bar ends 35, 37 of a photodiode 13 are not cut, the photodiode 13 remains secured to the rails 3, 5. The pressure pad of an assembling unit presses the LED 11 to the position rotated at 180 deg. in the same plane as the rails 3, 5 and the photodiode 13. The two hinge pins 31, 33 are flattened by stamping so that the LED 11 is not reversely rotated by an elasticity.
