Patent JP-H0278577-A (JP)
Title: Laser recorder
Inventor: OTA SHINICHI
IPC: H04N1/23
Filed: 1988-09-14
Abstract: PURPOSE:To conduct a pulse width modulation only in a part with low-exposure amount to prevent characteristics of synthesizing a laser and a photosensitive body from having a significantly non-linear shape by a method wherein a semiconductor laser modulates a light emission strength if an image signal has a value more than predetermined and modulates a light emission time if it has a value not more than predetermined. CONSTITUTION:If image data is more than a predetermined value 12, a multiplexer 6 selectively outputs the input image data. The data is converted to an analog signal by a D/A converter and turned to an electric current signal by an electric current amplifier 8 to drive a semiconductor laser 9. Namely, a digital comparator 13 outputs a high-level signal if the output of a look-up table 5 is more than the predetermined value 12 in the comparison of the output of the table 5 with the predetermined value 12. This output controls the multiplexer 6 so that it selectively outputs the input from the table 5 at high level. On the contrary, if the output of the table 5 is not more than the predetermined value 12, the digital comparator 13 outputs a low-level signal to make the multiplexer 6 output the predetermined value. In this manner, if the image data which has been converted by the look-up table 5 is more than predetermined, the drive current for the semiconductor laser 9 is analog-modulated; if it is not more than predetermined, the drive current is subjected to a pulse width modulation as it is constant.

Title: Method and device for forming gas curing type casting mold
Inventor: KITAZAWA SADAO
IPC: B22C15/24
Filed: 1982-12-24
Abstract: PURPOSE:To reduce a molding cycle time by blowing curing gas through an auxiliary blow port in parallel with the operation for exchanging a blow head and a gushing head upon completion of blowing of molding sand through a main blow port. CONSTITUTION:A blow head 28 is brought into tight contact with the peripheral edge of a main blow port 26 and blowing of molding sand is accomplished. Curing gas is supplied from a gas supplying device 34 in accordance with the detection signal when the blowing of the molding sand is completed, and said gas is blown into a cavity 24. The blow head 28 with which the blowing of the molding sand is completed is retreated, and a main gushing head 30 is brought into tight contact with the peripheral edge of the port 26. A selector valve 54 is changed over in accordance with the detection signal so that an auxiliary gushing head 46 is communicated with a gas discharging device 40 and the head 30 is communicated with the device 34. The blowing of the curing gas into the cavity 24 from the head 30 through the port 26 is therefore accomplished and the molding sand in the cavity 24 is cured.

Title: Doppler detecting circuit for fm sonar signal
Inventor: FUJITA RYUICHI
IPC: G01S15/52
Filed: 1985-10-18
Abstract: PURPOSE:To hold a signal-to-reverberation ratio in a good state by an FM signal, and also to detect quantitatively a Doppler by dividing a frequency band into two, and detecting the difference of a signal energy having each band. CONSTITUTION:The amplitude of the FM signal reflected or emitted from a mobile target is binary-coded by a limiter 4, and only frequency information is extracted. As for the output signal of the limiter 4, its frequency band is divided into two to the upper and the lower parts by the first and the second band pass filters 5, 6. Also, only one output signal is delayed by a delaying circuit 7, both signals are detected by the first and the second detectors 8, 9, and thereafter, from a differential amplifier 14 being a comparing part, the difference of each output signal is outputted. In this way, when it becomes necessary to detect a Doppler in the course of catching a moving target in a state that a signal-to-reverberation ratio is good, by the FM signal, the signal- to-reverberation ratio is deteriorated by switching to a PCW (pulse continuous wave), and a problem that the target is lost is prevented.

Abstract: PURPOSE:To increase drain withstanding voltage by adding a process in which the surface of a semiconductor substrate is etched to a gate-patten forming process to lower the concentration of a drain layer in the vicinity of a gate. CONSTITUTION:An impurity is diffused to a semiconductor substrate 21 to form source-drain layers 24, and an SiO2 film 26 is shaped onto the layers 24.

An oxide film 29 remaining in a region serving as a gate is removed, and a gate oxide film 30 is shaped onto a region from which the opening sections 28 and the oxide film 29 are removed, while shource-drain sections are driven in. Accordingly, impurity concentration in the source-drain regions is lowered in an etching section, and increased in a section not etched.
