Title: Synchronizing signal circuit
Inventor: TSUJIHARA SUSUMU
IPC: H03L7/14
Filed: 1995-01-09
Abstract: PURPOSE:To provide a synchronizing signal circuit which can normally construct a PLL even when the input synchronizing signals are omitted or discontinuous. CONSTITUTION:The omitted input synchronizing signals are supplied through an input terminal 1 and given to an AFC circuit 2 consisting of a phase discrimination circuit 5, an LPF 6, a voltage control oscillation circuit 7 and an integration circuit 8. The circuit 5 integrates the oscillation output signal received from the circuit 7 by the circuit 8 and compares this integrated signal with the input synchronizing signal in terms of levels to detect a phase difference between both signals. Furthermore the circuit 5 is identical with a symmetrical phase discrimination circuit that is balanced to the input synchronizing signal and therefore excels in the resistance to the impulsive noises and the weak electric field characteristic. Thus the output DC potential never extremely varies even if the input synchronizing signal is omitted or supplied to the circuit 5. Therefore the output waveform of the circuit 7 has its frequency and phase approximately equal to those of the input synchronizing signal even when this signal is omitted.

Title: Keyboard device
Inventor: TANAKA KAZUHIKO
IPC: G06F1/16
Filed: 1992-01-08
Abstract: PURPOSE:To miniaturize the keyboard device in the case of housing it without damaging operability in the case of using it and to use a keyboard even in the miniaturized state by widening the pitches of keys at the keyboard in the case of use in comparison with a housed state. CONSTITUTION:The keyboard is composed of a key unit part 1 and a frame part 2, and the frame part 2 is composed of the three parts of frames 21, 22 and 23. Among these frames, the frames 21 and 22 are integrated and only the frame 23 is slid. Since the frame 22 is housed in the frame 23 in the case of housing, the external form of the keyboard can be reduced. Therefore, the positions of the keys are slit and the pitches of the keys in the case of housing the keyboard are made narrower than the state of using the keyboard. Thus, the keyboard can be miniaturized almost without changing the thickness of the keyboard in the case of housing it, and the keyboard can be used even in the state of miniaturizing it for housing.

Title: High tensile structural steel for pressure vessel
Inventor: WATANABE SEIICHI
IPC: C22C38/00
Filed: 1981-01-08
Abstract: PURPOSE: To obtain a steel having superior hydrogen attack resistance and superior allowable stress characteristics at high temp. and maintaining the high toughness even through stress relief annealing after welding by adding Cr to a C-1/2Mo steel or further adding Cu or Ni.  
     CONSTITUTION: This steel consists of, by wt., 0.07W0.22% C, 0.05W0.50% Si, 0.10W0.95% Mn, 0.10W0.48% Cr, 0.45W0.60% Mo, 0.005W0.100% sol. Al and the balance Fe with inevitable impurities or further contains ≥1 kind of 0.10W0.50% Cu and 0.10W1.00% Ni if necessary. Cr enhances the hardenability during normalizing and prevents carbide from coarsening during stress relief annealing with no considerable increase in cost, yet less than the lower limit of Cr produces an insufficient effect, and more than the upper limit of Cr deteriorates the weldability. Cu and Ni enhance the hardenability during normalizing, and they enhance the strength and toughness, respectively, yet less than the lower limits of Cu and Ni do not produce the desired effects. More than the upper limit of Cu causes surface cracking and weld hot cracking, and more than the upper limit of Ni results in a higher cost.

Title: Absorption type hot-cold water supply apparatus
Inventor: SHIMAMURA MASAYUKI
IPC: F25B30/04
Filed: 1994-01-12
Abstract: PURPOSE:To simplify a cooling-heating changeover piping system to reduce the piping space by providing a refrigerant bypass pipe with an orifice between a refrigerant outlet pipe and a refrigerant tank. CONSTITUTION:During heating operation, refrigerant that condenses in arm evaporator 1 flows along two routes: one is to a refrigerant delivery pipe 6 after passing through the inside of a refrigerant pump 2, and the other is to the refrigerant delivery pipe 6 via a refrigerant bypass pipe 22. Therefore, the pressure loss is reduced, causing an increase in the flow rate of the refrigerant flowing to an air lift pump 17. During cooling operation, as the flow rate of refrigerant flowing along line refrigerant bypass pipe 22 is regulated by an orifice 23 although the refrigerant pump 2 is in operation, the flow rate of refrigerant supplied to a refrigerant sprayer can be controlled. Therefore, the refrigerant changeover piping system can be simplified to result in a reduction in piping space.
