Title: Parallel feedback amplifier
Inventor: MIKAMURA YASUKI
IPC: H03F3/345
Filed: 1989-05-17
Abstract: PURPOSE:To obtain a high gain with broad band and to cause the amplifier hardly to be oscillated by connecting an amplifier and a differential amplifier in two-stage cascade connection so as to obtain an inverted output with respect to an input signal and applying negative feedback to the input in the amplifier suitable for pre-amplification of an optical receiver. CONSTITUTION:The signal given to an input terminal IN is inverted at an amplifier 1 and amplified by a differential amplifier 2. Part of the inverted signal is fed back to the input terminal through a feedback resistor RF, then oscillation hardly takes place. Since the amplification is implemented by two- stage configuration, a larger gain is obtained in comparison with the case with one stage amplification. Thus, the resistance of the feedback resistor RF is decreased for the same gain, then low noise is attained for the same band as the vase with one stage amplifier configuration.

Title: Low-pass filter circuit
Inventor: TANAKA YASUSHI
IPC: H03H11/04
Filed: 1984-06-13
Abstract: PURPOSE:To attain high speed response even with a setting where a ripple of an output voltage is decreased by providing a diode to an input circuit of a phase inverse amplifier circuit so as to discharge an electric charge of a feedback circuit. CONSTITUTION:The time constant of the feedback circuit 23 is selected so that the ripple of the output voltage E0 at normal reception state is decreased. Further, a diode 19 is connected to an input circuit of the phase inverse amplifier circuit 22 and the electric charge of the circuit 23 is discharged through the diode 19. Thus, the response when the voltage E0 gets higher regardless of the selection of the time constant decreasing the tipple is quickened.

Title: Substrate heating member
Inventor: HORIE KUNIAKI
IPC: C23C16/46
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To uniformly heat a substrate over a long period by equipping a heating element for heating and a soaking plate for uniformizing the heat of the heating element and transferring to a heating plate on the back surface of the heating plate, on which the substrate is placed, and forming a stress relaxation groove on the joint surface of the soaking plate to the heating plate and keeping the close contactness of the heating element to the soaking plate. SOLUTION: The heat from the heating element 12 flows in the soaking plate 20 in the thickness direction and along the plate surface to uniformize the temp. In such a case, because the front surface groove 22 and the back surface groove 24 are formed with a shift to each other, a heat flow passage part 26 is not made narrow to have the flow passage cross section for heat transfer to maintain the uniformity of heat in the soaking plate 20. When both members are elevated in the temp., the internal stress in the vicinity of the joint surface of the soaking plate 20 to the heating plate 16 is generated by the difference of the coefficient of thermal expansion. Because the soaking plate 20 is divided into sections by the surface grooves 22 to be separately deformed, the stress is not concentrated. The internal stress generated between the soaking plate 20 and the heating plate 16 by the difference of the coefficient of thermal expansion is relaxed with the expansion of the surface grooves 22 of the soaking plate 20 in this way and the stripping of the soaking plate 20 is prevented.

Title: Chattering noise eliminating circuit
Inventor: NAKAZAWA KOUJI
IPC: H03K5/1252
Filed: 1979-09-28
Abstract: PURPOSE:To make it possible to eliminate a chattering noise securely by resetting two FFs by detecting dissidence between two FF outputs by exclusive OR with a clock signal at constant intervals of time. CONSTITUTION:When a chattering noise is inputted to inputs S of FFs 13A and 13B having been preset yet, logic L of the input component holds both outputs Q of FFs 13A and 13B at logic H and output 16 of gate 14 at logic L. When there is no noise, on the other hand, one output Q is at logic H, and the other at logic L, generating output 16 of logic H. In this case, gate 25 outputs signal 15 as output signal 17. Since signal 16 has logic L while the noise is generated, logic L from gate 25 is outputted as it is. Output 17 is fetched into FF24 at the rise of output clock 18 of oscillator 20 and then latched. Then, FFs 13A and 13B are reset immediately by MM22. Output 19 of FF24 generated as mentioned above is shown in the figure and the noise removed.

Title: Shape measuring apparatus
Inventor: NAKASHIRO MASAHIRO
IPC: G01B11/24
Filed: 1987-05-21
Abstract: PURPOSE:To obtain an apparatus wherein a response time is rapid and proportional relation is present between beam spot moving quantity and a detection signal over a wide range, by making a received beam spot elongated on a multisegment photodiode composed of at least two elements. CONSTITUTION:The laser beam emitted from a beam source 1 is allowed to irradiate an object 3 to be measured by a projection lens 2. The beam spot generated on the object 3 to be measured is condensed as elongated beam by a beam receiving lens 4 and a cylindrical lens 6 and the position thereof is detected by a multisegment photodiode 5. When the object 3 to be measured moves in the optical axis direction of the beam source, the elongated spot moves on the photodiode 5 in proportion to the momentum of said object 3 to be measured. Therefore, by detecting the moving quantity of the elongated spot, the displacement of the object 3 to be measured can be measured.

Title: Image pickup device
Inventor: KATOU TOKUZOU
IPC: H04N5/243
Filed: 1983-07-07
Abstract: PURPOSE:To attain image pickup of an object level at a proper level by discriminating the distributing state of a luminance at a part excluding the center of a screen resulting in changing the AGC characteristics in a device changing over the AGC characteristics. CONSTITUTION:When an output of an amplifier 10 of a diaphragm loop of the prestage is added to a gate pulse in synchronizing with a horizontal, vertical television rate formed by a gate pulse generating circuit 18 at a gate circuit 17, only the video signal at the peripheral part of a screen is gated and compared with a set reference voltage V3. Since the luminance distribution of the part except the midpoint of the screen is discriminated in this way, even if a level having a high luminance is incoming, it is not detected by a peak value rectifier circuit 15 and in a scene where the luminance of the center of the screen is high and other are dark the rectifying characteristics of the AGC loop is a peak value rectification, the AGC is operated so that a part having a high luminance level in the screen becomes a proper level.

Title: Output device of q-switched pulse laser
Inventor: OKA KIYOSHI
IPC: H01S3/117
Filed: 1990-05-17
Abstract: PURPOSE:To obtain a Q-switched pulse laser beam whose energy and peak output are definite even when the repetition number of the Q-switched pulsed laser beam is changed by providing the following: a solid-state laser medium; a pumping lamp; an optical resonator; an acoustooptic Q-switch arranged inside the optical resonator; a Q-switch drive circuit; and an excitation-amount control means. CONSTITUTION:Electric power is supplied to individual pumping lamps 3, 4 from a variable power supply 30 for the pumping lamps; a solid-state laser medium 2 is exciated. At this time, while high-frequency electric power is supplied to a Q-switch 8 from a Q-switch drive circuit 10, a loss inside a resonator 5 becomes large and a laser oscillation is stopped. When a laser oscillation state is caused suddenly, the induced emission by a large population inversion inside the medium 2 is executed instantly, and a high-peak Q-switched pulsed laser beam is output from an output mirror 7. The Q-switch drive circuit 10 applies a repetition-frequency signal to the current control terminal of the variable power supply 30 through a frequency/voltage conversion circuit 21, a limiter circuit 22 and an isolating amplifier 23 in an excitation- amount control circuit 20. Thereby, the individual pumping lamps 3, 4 emit light at an excitation amount which is proportional to the repetition frequency of the Q-switch 8.
