Title: Method and device for laser recording
Inventor: OHARA YUJI
IPC: G03G15/04
Filed: 1987-02-19
Abstract: PURPOSE:To record a high-gradation image by light intensity modulation at a high speed by measuring the intensity of a light beam when the output of semiconductor laser light is converged nearly into a stable state. CONSTITUTION:A laser recording device is constituted by providing the semiconductor laser 1, a beam scanning system which scans the light beam 4 projected by the semiconductor laser 1 on a photosensitive material, and a laser operation control circuit which generates a light emission level command signal corresponding to the image signal and controls the driving current of the semiconductor laser 1 according to the signal to modulate the light intensity of the laser beam. Then light beam intensity corresponding to the value of each test signal S10 is obtained when the test signal S10 is inputted to a laser operation control circuit so as to generate the correction table 40. At this time, the light beam is measured when the output of the semiconductor laser is converged nearly into the stable state to obtain the same result with the measurement of the light beam intensity in the middle of transient variation at the time of image recording without correction.

Title: Semiconductor memory
Inventor: RAI YASUKI
IPC: H01L29/792
Filed: 1979-03-27
Abstract: PURPOSE:To perform a memory function for a semiconductor memory stably even if strain is thermally produced thereat by increasing the thickness of the insulating film in the vicinity of the end surface of a channel at the portion except the portion making contact with a source and a drain. CONSTITUTION:A first insulating film 5 is formed in approx. 600Angstrom  on a channel region, only the central portion 52 is selectively etched to form in approx. 200Angstrom . Thus, the film 5 may become thicker than the central portion 51 in thw vicinity of the end surface making no contact with source 2 and drain 3. According to this configuration since the portion 51 is formed thickner, no crack occurs nor electric field is concentrated even if strain is applied to the portion 51 due to the difference in thermal expansion coefficient between the field oxide film 11 and a substrate 1. Thus, no apprehension of short is expected to perform stable memory function.

Title: Automatic adjusting circuit for pulse width
Inventor: OKINO TAKAYUKI
IPC: H03K5/05
Filed: 1981-03-14
Abstract: PURPOSE:To adjust the pulse width of an output pulse to preset one automatically by counting an error in pulse width and adding the result of the counting to an input pulse. CONSTITUTION:An input pulse is supplied through delay circuits DL1-DLn to a selecting circuit SEL which selects the outputs of the respective delay circuits. The output of an OR circuit G2 supplied with the output of the selecting circuit SEL and the input pulse is sent to counters CRT1 and CRT2 which count pulses from a pulse oscillator OSC to count the period of ''1'' and that of ''0''. On the basis of the difference output of a difference circuit SUB inputting the outputs of both the counters, the selection of the selecting circuit SEL is controlled. This difference output corresponds to an error in pulse width and the selecting circuit SEL adds the outputs of the delay circuits DL1-DLn to the input pulse selectively. Thus, the pulse width of the output pulse is adjusted automatically to preset pulse width.
