Title: Driving method for semiconductor laser
Inventor: KITAGAWA SHUNJI
IPC: B41J2/44
Filed: 1985-11-18
Abstract: PURPOSE:To prevent fluctuation in temperature and decrease in optical output, by deforming a modulating signal in a rectangular wave into a form, in which a corner at a rising part is removed, so as to obtain a driving signal, applying the signal to a semiconductor laser, and suppressing the temperature increase, when the driving signal is applied, to the utmost. CONSTITUTION:A driving signal (c) in pulse waveform, which undergoes modulation, is applied to a semiconductor laser LD. At the time of rising of the modulating signal (a), an edge signal (b), whose polarity is reverse with respect to the modulating signal, is generated in synchronization with the rising timing of the modulating signal. The edge signal is superimposed on the modulating signal. Then the driving signal has a slowly increasing waveform. The driving signal is applied to the semiconductor laser LD before the rectangular wave reaches a peak. For example, when the modulating signal in rectangular waveform is inputted to a differential circuit 14, a differential waveform is generated and rectified in a rectifier circuit 15. The differential waveform at the falling part is removed. The differential waveform at the rising part becomes the waveform, whose polarity is inverted by an inverter circuit 16. The result is inputted into a superimposing circuit 17. The modulating signal is also inputted to the superimposing circuit 17. The differential waveform, whose polarity is inverted, is superimposed to the modulating signal. The driving signal 12, whose corner at the rising part is removed, is obtained and applied to the semiconductor laser LD.

Title: Object detector
Inventor: KUROSAKI HISASHI
IPC: G08B13/191
Filed: 1994-10-25
Abstract: PURPOSE: To detect an object while confirming the normality of a sensor by monitoring the sensor section periodically and outputting a danger signal upon detection of a failure regardless of a decision signal. CONSTITUTION: Cover members 4A, 4B of a protective cover 4 are provided with windows 9 which define predetermined a predetermined region of an object being monitored by pyroelectric sensors PH1 -PH4 . A light from an inspection signal generation means, i.e., an emission source 20, passes through another window 11 of the member 4B and enters into all pyroelectric sensors thus monitoring a sensor part 12. When a rotor 3 is rotated through a motor, all pyroelectric sensors senses the infrared rays 20 of the light signal 20 every time when the light signal 20 passes through the window 11. When each pyroelectric sensor is normal and no object is present in a predetermined region, a logical value 1 representative of a safety signal is outputted from a second AND gate.  When an object is present, the sensors PH1 -PH4 sense the infrared rays and if any one pyroelectric sensor fails, the second AND gate outputs a logical value O representative of a danger signal. Consequently, an object can be detected while confirming normality of the sensor section 12.

Filed: 1990-10-01
Abstract: PURPOSE:To obtain a compact input device having high operability and less troubles by providing a pair of pressure sensors which cross to each other and can generate the signals independent of each other and a means which transmits these independent signals to an arithmetic unit. CONSTITUTION:An arithmetic unit processes the position data on a cursor and a pointer and displays them on a display device based on those position data. Then a pair of pressure sensors 8 and 10 are set crossing to each other. An input device has such a constitution. When an operator touches both sensors 8 and 10 with his/her fingers, the independent signals are generated. These signals are sent to the arithmetic unit as the position data and the cursor and the pointer are moved on a display screen. Thus the cursor and the pointer are moved on a display screen. Thus the cursor, etc., can be moved over a wide range even with use of a small area on a desk since just repetitive touches are needed to both sensors 8 and 10. In such a constitution, a compact input device is obtained with high operability and less troubles.
