Title: Laser deflector
Inventor: MATSUURA TADASHI
IPC: G02B7/182
Filed: 1987-06-30
Abstract: PURPOSE:To reduce troublesome processes for balancing at the time of coupling a mirror surface part with a rotary shaft by forming a slanting mirror surface at part of the rotary driving shaft of a motor integrally. CONSTITUTION:A pyramidal mirror is a reflecting medium which has the mirror surface slanting to the rotary shaft, reflects a light beam incident along the rotary shaft by the mirror surface, and deflects the reflected beam by the rotation of the pyramidal mirror. The pyramidal mirror is united preferably with the rotary driving shaft 40 of the rotary motor as a rotary driving system so as to simplify the relation between the rotary driving system and pyramidal mirror as much as possible. For the purpose, there are a method of fixing the pyramidal mirror itself to the rotary driving shaft 40 and a method of forming the rotary driving shaft into the pyramidal mirror by forming and machining the rotary driving shaft 40 itself. Consequently, an improved laser deflector is obtained which omits processes for size control, rotary balancing, etc., at the time of coupling when the mirror surface MI is provided to the rotary driving shaft 40 of the motor.

IPC: H01L21/8238
Filed: 1986-07-14
Abstract: PURPOSE:To bring down the high level of an output buffer as low as possible and to perform a high speed switching operation by a method wherein one or a plurality of diodes, which are formed on the same substrate, are connected in series to the part located between an earthing wire and the output terminal of the output buffer of a CMOS semiconductor integrated circuit. CONSTITUTION:The output terminal 6 of a CMOS integrated circuit device 1 is connected to the input of a TTL circuit device. In this case, four diodes 7 formed on the same substrate are connected between the output terminal 6 of the output buffer 3 of the CMOS integrated circuit device 1 and an earthing wire. When the internal potential of said diodes is set at 0.7 V, the potential of the four diodes becomes 2.8V, and when the potential of said output terminal exceeds 2.8V, the diodes are turned ON, and the voltage of said output drops to 0-2.8V. As a result, the potential is to be changed from 2.8V to 1.4V in order to bring high level to low level, so the switching operation can be performed at the speed higher than the case where potential is changed from 5V to 1.4V.

IPC: H03M1/12
Filed: 1994-07-15
Abstract: PURPOSE:To continuously detect the waveform peak values to an arbitrary waveform to be measured by subjecting the measuring waveform signal to A/D conversion on the basis of the zero cross of a differentiated output waveform signal. CONSTITUTION:An input terminal 1 sends a measuring waveform signal SA both to an A/D-converting circuit 5 and to a differentiation circuit 2. A circuit 2 differentiates the signal SA for obtaining a differentiated output waveform signal SB. A comparator circuit 3, to which the signal SB has been input, sends an output signal SC for changing over an H level and an L level at the zero cross of the signal SB to an edge detecting circuit 4. The circuit 4 detects the edges of rising and decreasing of the signal SC, and outputs this as an A/D-conversion command signal SD to an A/D converter 5. The A/D converter 5 subjects this signal SA to A/D conversion. At that time, the conversion is started, for instance, at the rising edge of the signal SD, and conversion data SE consisting of respective peak data DT1 to DT6, etc., that have been subjected to A/D conversion at timings T1 to T6, etc., are obtained. Thus, the A/D- conversion data of the waveform peak values of the signal SA can be continuously obtained.
