Title: Reset circuit
Inventor: ADACHI YASUSHI
IPC: H03K17/22
Filed: 1989-05-16
Abstract: PURPOSE:To reduce the number of terminals of an integrated circuit and the number of externally mounted components in the case of constituting the title circuit with the integrated circuit by using a voltage source having a time constant whose major object is the application other than reset operation so as to reset just after application of power. CONSTITUTION:The rising speed of a voltage source 4 is slower than the rising speed of a power voltage with a time constant comprising a dynamic resistance through which a capacitor 5 is charged by the voltage source 4 and a capacitance of the capacitor 5 at application of power. A logical threshold voltage Vth of a logic circuit 7 is set between a voltage just after application of power supply of the voltage source 4 and a voltage when a sufficient time elapses after application of power. The output of the logic circuit 7 connects to a reset terminal 8 of a device 1 and when the reset terminal 8 is logically at a high level, the device 1 is reset. Thus, when the device 1 is constituted by the integrated circuit, the number of externally mounted capacitors and terminals for connecting the externally mounted capacitors is reduced for the resetting just after application of power.

Title: Gas laser
Inventor: ISHIKAWA KEN
IPC: H01S3/0977
Filed: 1990-05-15
Abstract: PURPOSE:To prevent a gas laser medium in a main discharge space part from being deteriorated in its early stages by a method wherein the main discharge space part provided with main electrodes and a space ionization discharge space part provided with spare ionization electrodes are partitioned from each other and at the same time, an introducing part for introducing ultraviolet rays generated in the space ionization discharge space part in the main discharge space part is formed. CONSTITUTION:When spark discharge is generated between pin electrodes 16, impurities are generated along with ultraviolet rays. The impurities are circulated in a space ionization discharge space part 6 by a second fan 18 along with a gas laser medium in the space part 6, while a gas laser medium hardly containing the impurity is circulated in a masin discharge space part 5. The gas laser mediums being circulated in the space parts 5 and 6 are set at almost the same pressure. As a result, it is never generated that the impurity-containing gas laser medium being circulated in the space part 6 flows in the space part 5 through through holes 15 bored in a second sealed vessel 3 and is mixed with the gas laser medium, which is circulated in the space part 5 and does not contain the impurity. Accordingly, the gas laser medium in the space part 5 is never deteriorated in its early stages.

Title: Variable gain amplifier
Inventor: HASE HIDEKAZU
IPC: H03G5/16
Filed: 1993-05-26
Abstract: PURPOSE:To vary the gain over a wide range without the use of a variable resistor whose resistance is widely changed by varying a voltage applied to a gate electrode of an inserted transistor(Tr). CONSTITUTION:A signal is amplified by a signal amplifier Tr1 using a Tr3 of a constant current circuit as a load and extracted by a buffer Tr6. Since the operating current of the Tr1 and a signal feedback Tr2 is kept constant by the Tr3 of the constant current circuit, the amplified signal returns to the Tr2 via a level shift diode 7 to decrease the current in the Tr1 thereby reducing the amplification degree of the Tr1. A maximum value of the amplification degree depends on a ratio of the gate width between the TRs 1, 2. When a Vc(>0) is simultaneously applied to a gate electrode of a Tr4 inserted between the Tr1 and a Tr3 of the constant current circuit being a load and a gate electrode of a Tr5 inserted between the Trs 2, 3, the amplifier circuit shows a maximum gain. When a Vc(<0) is applied, the operating current of the amplifier circuit comprising the Trs 1, 2, 3 is very small and the gain is less.

Abstract: PROBLEM TO BE SOLVED: To provide a centrifugal pump which is improved in the arrangement and combination form of blades for remarkably reducing a noise level. SOLUTION: A centrifugal type impelller has eight stripes of spiral main blades 20 (20F, 20B) extending from a boss part 15a toward an outer periphery 15b on a back shroud at equal intervals, and in addition, has a front shroud 17 equipped with an axial flow introducing hole 17a, and a gap between main adjacent blades 20, 20 is provided with two stripes of auxiliary blades 60, 70 which extend from the boss part 15a to an outer periphery crossing over inner periphery side discontinuous parts 62, 72, and are different in blade length. The auxiliary blade 70 approaching the rear side of the main blade 20F is shorter in comparison with the blade length of the auxiliary blade 60 approaching the front side of the main blade 20B. Since pressure just before the main blade 20B is lowered by the auxiliary blade 60, and pressure just behind the main blade 20F is raised by the auxiliary blade 70, pressure gap before and behind the main blade is reduced, and noise is thereby restrained.
