Patent JP-H01219425-A (JP)
Title: Microwave oven with piezoelectric element sensor
Inventor: KASHIMOTO TAKASHI
IPC: F24C7/02
Filed: 1988-02-29
Abstract: PURPOSE:To enable always stabled finished state of heated objects even under a repetitive use by a method wherein a temperature compensating element for sensing an atmosphere temperature of a piezoelectric element sensor is applied and a gain of an amplifier is made variable in response to a signal of the compensating element and then a set-off frequency band of a filter is limited. CONSTITUTION:Although an output voltage of a piezoelectric element sensor 1 is decreased as an atmosphere temperature is increased, an amplification gain of an amplifier 18 is set to have a decreased resistance valve of a thermistor 6 as the atmosphere temperature is increased, a stable output can be attained. However, the output voltage of the piezoelectric element sensor 1 is widely disturbed due to a humidity even if the same temperature T is applied in response to a selection of a cut-off frequency band of the filter 17. However, if the cut-off frequency band of the filter 17 is selected at 4Hz or so, an influence of temperature is scarcely applied. So, low-pass filters 27 and 28 are constructed to cause the output signal of the piezoelectric element sensor 1 to have a passing band up to 4Hz band.

IPC: H01L23/08
Filed: 1980-04-11
Abstract: PURPOSE:To prevent a defective product in which lead wire alone is mixed in finished products by a method wherein articles are drawn out from jigs and carried out along a nonmagnetic guide by using a magnet. CONSTITUTION:When a jig 7 which has been sealed and released from a weight comes to the side of a guide 30, a magnet 32 rotates rightward so as to draw out the upper lead 3 in the jig 7. The upper lead 3 with no lower lead is readily drawn out to pass through a heat sink 15 and a hole 14 in a guide plate 13 and moved sliding along the circular outer surface of the guide 30 by the rotational movement of the magnetic poles with the guide 30 therebetween. When the upper lead 3 has reached a chute 31, the attraction force to the guide disappearance. Therefore, the upper lead 3 slides down the chute 31 under its own weight. As a result, there is no jig containing only the upper lead at all in the jigs having passed through said stage. By said method, upper leads with no lower leads are automatically removed in a noncontact manner. Accordingly, there is no possibility of bending good leads in its vicinity, and working efficiency improves.

Abstract: PURPOSE:To eliminate the necessity of moving ADPCM data within a buffer memory by loading the adding value of an adder when the counted value of an address counter becomes larger than the subtracting value of a subtractor after the completion of the writing of the last data. CONSTITUTION:A comparator 16 monitors the counted value of an address counter 11 and writes the last data of a sector N into a buffer memory 24. When the counted value of the address counter 11 becomes larger than a subtracting value Ad-2352 of a subtractor 14, a comparison output is generated, an adding value Ad+2352 of an adder 15 is loaded to the address counter 11 after the completion of writing the last data of the sector N, the data regions of ADPCM data are avoided and the data in a sector (N+1) are written into the buffer memory 24. Thus, the data regions are avoided and the next sector data are written without moving ADPCM data within the buffer memory.
