Title: Transistor driving circuit
Inventor: KAWAGISHI KENJI
IPC: H03K17/61
Filed: 1982-04-27
Abstract: PURPOSE:To reduce the size of a base driving circuit, by providing a transistor (TR) for carrier discharge between the base and emitter of a main TR and arranging a switching element between its base and emitter through a transformer which has the opposite-polarity input and output windings. CONSTITUTION:A transformer 9 for turning on a power TR constitutes the 1st control circuit which supplies a forward base current to a TRQ2 including a TRQ1 for on-control and a rectifying diode 10. The input winding 13 of a transformer 15 for turning off the power TR is connected in series to a TRQ4 for off-control and a resistance R5 for current limitation constituting a switching element, forming the 2nd control circuit. The output winding 14 of this transformer 15 has the opposite polarity to the winding 13 and is connected between the base and emitter of an NPN type off TRQ3 as the TR for carrier discharge. The TRQ2 is driven by control signals from the 1st and the 2nd control circuits.

Title: Manufacture of aromatic amine compound
Inventor: BARUDE KUMAARU BANTORISHIYU
IPC: C25B3/25
Filed: 1991-04-03
Abstract: PURPOSE: To make it possible to efficiency reduce an arom. nitro compd. to an amine compd. by reducing a titanium (IV) oxysalt in an acidic aq. electrolyte and using the resulted titanium (III) salt product as a reducing agent.  
     CONSTITUTION: A dissolved titanium (III) salt is formed by electrochemically reducing a titanium (IV) oxysalt, more preferably titanium (IV) oxysulphate in the acidic aq. electrolyte soln. The arom. nitro compd. is chemically reduced to the amine compd. in an acidic aq. reaction medium by using the titanium (III) salt product as the reducing agent. The titanium (III) salt has good solubility in an aq. strong acid soln. and may be produced without forming the titanium salt precipitant which affects current efficiency. The reoxidation product of titanium (IV) formed from the titanium (III) reducing agent is recovered during the reduction of the nitro compd. and is used as a starting material for producing the titanium (III) reducing agent.

Title: Travel body detection device
Inventor: TSUGE MASAKUNI
IPC: G08G1/0962
Filed: 1994-03-17
Abstract: PURPOSE:To maintain the importance of indication without causing any trouble on a driver by receiving a corresponding return signal and indicate an alarm or the like, only when a demand signal is transmitted from both sides of an own vehicle. CONSTITUTION:When a vehicle speed is equal to or less than the prescribed value (e.g. 40km/h), a control device 1 instructs an oscillator 3 to issue a demand signal (a signal to demand a return signal when a mating vehicle is within the preset distance from an own vehicle). The oscillator 3 inputs an oscillation signal to a frequency mixer 4, and amplifies at a step 6 the demand signal combined with a signal synthesized with a PLL synthesizer 5 for transmission at a step 7. Concurrently, a timer 2 starts a counting process. Furthermore, when a counted time (corresponding to a distance up to the mating vessel) exceeds the preset time upon receipt of the return signal, only an indicator lamp 13 is made to light, thereby informing that the mating vehicle exists at a position not so near within the preset distance. Also, when the counted time is equal to or less than the preset time, the lamp 13 is made to flash and a buzzer 15 is sounded, thereby informing that the mating vehicle exists at a considerably near position.

Abstract: PURPOSE:To detect easily a distance up to a subject to be measured by forming the image of a reflected light beam available from irradiating the subject to be measured by a light source fitted on a case on the light receiving element of a case bottom by means of a reflecting mirror and a movable lens and obtaining the position where the lens moves. CONSTITUTION:The laser beam source 2 is fitted outside the bottom plate 1a of the case 1 to irradiate the subject to be measured 3. A motor 4 is fitted inside the case 1, and a threaded-rod 7 turning through an output spindle 4a and gears 5 and 6 is fitted on the case 1 in the longitudinal direction. A moving frame 8, which advances and retreats due to the turn of the threaded-rod 7, is fitted on a moving frame 8. The reflecting mirror 8c fitted obliquely on the opening of the frame 8 projects the irregularly reflected light beam from the subject to be measured 3 on the light receiving element 9 at the bottom of the frame 8 through a lens 11. A controller 16 detects the output of the light receiving element 9, drives motors 4 and 14 and condenses light beams. It obtains a distance from an interface between the lens 11 at that time and the light receiving element 9 and the subject to be measured 3. Thus optical axis matching and focusing are executed simultaneously, and measurement can be easily carried out at high accuracy.

Abstract: PROBLEM TO BE SOLVED: To change the frequency of a video clock so as not to affect display quality by providing a step of lowering the frequency of the video clock and a step of repeating this step until the changed frequency of the video clock becomes a prescribed frequency. SOLUTION: First of all, the timing to change the frequency of the video clock (Vclk) is detected (S110).
