Title: Switching power source circuit
Inventor: OKAMOTO AKIRA
IPC: H02M7/12
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a switching power source circuit a DC voltage compensating circuit which has incorporated therein, which supplies a DC voltage within the level for compensating the action of the circuit element of an IC, etc., mounted in the switching power source circuit with respect to the potential fluctuation of an input AC voltage supplied from an AC power source to the circuit element. SOLUTION: In a switching power source circuit 1 which rectifies an input AC voltage by means of a rectifier circuit D3 and supplies a prescribed voltage to a secondary-side circuit by impressing a pulse voltage upon a transformer T1, in accordance with an oscillation signal outputted from an IC 20 based on the rectified DC voltage from the circuit D3, the potential at the base electrode of a transistor Tr1 is fixed, when the value of the DC voltage outputted from the circuit D3 is larger than a prescribed value, because a reverse voltage having a reverse breakdown voltage value flows at a fixed level into a Zener diode ZD1. The DC voltage supplied to the IC 20 is compensated by interrupting the flow of the base current of the transistor TR1 and supplying electric power to the IC 20 from the auxiliary coil T3 of the transformer T1.

Title: Electric machining equipment with cutting wire
Inventor: INOUE KIYOSHI
IPC: B23H7/10
Filed: 1981-09-18
Abstract: PURPOSE:To heighten the velocity and accuracy of machining, by passing a wire electrode through a vibrating die to eliminate the twist or the like of the wire and thereafter feeding it to a machining section. CONSTITUTION:Spark erosion is caused on a work 8 by a wire electrode 1 while it is being wound from a drum 2 to another 3. A vibrating die 12 is provided between the drum 2 and a guide 6. The wire electrode 1 is drawn out through the die 12 to eliminate the twist or the like of the wire electrode. Since the die 12 is vibrating, a low drawing-out force is enough. Because the vibration is applied to the gap for the spark erosion, chips are well discharged. If electricity is supplied through a terminal 3 to heat the drawn-out part of the wire electrode 1, a much lower drawing-out force will be enough. The straightness of the wire electrode 1 is thus enhanced to heighten the velocity and accuracy of the spark  erosion.

Title: Rotation controlling mechanism for steam engine
Inventor: TAMURA MUNEO
IPC: F01B25/02
Filed: 1978-11-30
Abstract: PURPOSE: To enable to remote-control a steam engine used in a model railway or the like, by accomplishing speed change or reversing of rotation of carrier in a differential means driven by the steam engine by means of a motor, and actuating a valve for controlling steam flow.  
     CONSTITUTION: Steam supplied from inport 4 is introduced into cylinder 3 from either of intake 5, 5 selected by slide valve 7. Steam thus introduced into cylinder 3 causes motrion of piston 9 and hence piston rod 10, which in turn causes rotation of flywheel 23 and sun gear 16. While motor 38 is not operated, carrier 11 is not rotated since pin 21 and stopper 25 are engaged with each other by the rotation of  sun gear 16, so that slide valve 7 is not actuated. On the other hand, when worm  gear 37 is driven by motor 38, carrier 11 starts its rotation and slide valve 7 is  actuated by eccentric shaft 31 and others, so that operation of piston 9 and rotation  of flywheel 23 can be controlled.

Title: Communication terminal device with automatic recording system
Inventor: YAMAGUCHI NAOHIRO
IPC: H04M11/00
Filed: 1991-06-20
Abstract: PURPOSE:To confirm a message recorded by a non-owner during his call by calling and transmitting the message when the transmission of the recorded message is selected. CONSTITUTION:A flag A is set to '1' or '0' by a selection means selecting between an automatic recording function and a facsimile function. At this time, when the flag A is '0' and the automatic recording function is selected, a message indicating that the automatic recording function is being activated by an outgoing message OGM transmission means is transmitted to the non- owner (transmitter). Receiving this message, the transmitter transmits the necessary message, and such information is recorded in a recording part 13 by an incoming message ICM receiving means. When the transmitter intends to confirm the contents of his message during this call, a flag B activating a recorded message transmission selection means is set to '1' by operating a prescribed button. Thus, the ICM recorded in the recording part 13 during the call can be transmitted.

Title: Non-volatile semiconductor storage device
Inventor: YAMAGATA YASUJI
IPC: G11C16/16
Filed: 1992-05-15
Abstract: PURPOSE:To prevent overerase or undererase by changing the fluctuation in erasing speed by changing an erasing voltage by forming an insulation film between a floating gate and substrate of a transistor and an insulation film between a floating gate and substrate of a memory cell in the same process and giving almost the same film thickness. CONSTITUTION:At the time of erasing operation, a high voltage is applied to a high voltage power source terminal 1, a constant voltage is applied to a constant voltage terminal, and a constant current I flows between the drain and source of a transistor and also to a resisting element R. A voltage at a connecting point A is supplied to the source of a memory cell through a transfer circuit. When an insulation film between the substrate and a floating gate of the memory cell has become thin due to production dispersion, transistor substrate and the floating gate film also become thin because said insulation film is formed together with a transistor substrate and a floating gate insulation film in the same process, so that the voltage applied to the source line of memory cell drops. Therefore, the fluctuation of erasing speed can be corrected by changing the applied voltage.
