Title: Waveform shaping circuit
Inventor: YAMADA MASAYA
IPC: H03K5/08
Filed: 1988-07-11
Abstract: PURPOSE:To obtain a rectangular wave signal whose threshold value follows a drift of a DC level and whose level width is correct by detecting an upper peak value and a lower peak value of a demodulation signal, and deciding a variable threshold value as a mean value of the values or its vicinity. CONSTITUTION:An upper limit peak hold circuit obtaining an upper limit peak value U of an output signal W consists of a diode 9, a capacitor 11 and a resistor 10. A diode 12, a resistor 13 and a capacitor 14 constitute a lower limit peak hold circuit obtaining a lower limit peak value D. A 3rd amplifier 16 is a voltage follower to decrease the impedance of the lower limit peak value D. Then a voltage division circuit dividing the upper limit peak value U and the lower limit peak value D and a comparator 19 binarizing the demodulation signal W by using an intermediate value between the values U and D obtained by the voltage dividing circuit as a threshold value Vth are provided. Thus, the DC level of the demodulation signal is subject to drift, the rectangular wave signal with correct H level width and L level width is obtained.

Title: Pulse control type solenoid valve
Inventor: ALSENZ RICHARD H
IPC: F16K31/06
Filed: 1985-08-07
Abstract: A pulsed controlled solenoid flow control valve suitable for use in a closed vapor cycle air conditioning system is disclosed. A pulsewidth modulated control signal is generated for cyclically opening and closing the flow through the expansion valve. The duty cycle of the pulsed control signal determines the average flow rate through the valve. An exponential response control curve is used in conjunction with an integrator offset to obtain a single set point control operating point for all flow rates through the valve, where a given change in the second superheat of the evaporator produces the same percentage change in flow rate regardless of the flow rate.

Title: Hydromechanical continuously variable transmission
Inventor: SAWAZAKI TOMOO
IPC: F16H47/04
Filed: 1986-07-23
Abstract: PURPOSE:To keep off the blow-up of engine speed due to the occurrence of an under lap state at the time of a changeover of ranges, by properly setting the feed-discharge timing of pressure oil to bot low and high clutches at the changeover of both low and high ranges. CONSTITUTION:For example, a changeover from a low range to a high range is carried out in the following process that pressure oil is discharged out of a low clutch 22 having so far been in a clamped state, releasing this clutch 22, and the pressure oil is fed to a high clutch 23 having so far been in a released state, then the clutch 23 is clamped. And, the changeover from the high range to the low one is carried out by doing feed and discharge of the pressure oil reversely. In either case, feed of the pressure oil to the clutch at the side to be clamped is started earlier for the specified time than discharge of the pressure oil from the clutch at the side to be released so that hydraulic pressure of both clutches all produce such timing that becomes more than the irreducible minimum hydraulic pressure for maintaining the clamped state. Therefore, an under lap state at the time of replacing the clamp and release of both these clutches is eliminated.

Title: Formation of pattern and exposing device
Inventor: TOKUMITSU HAJIME
IPC: H05K3/00
Filed: 1984-08-21
Abstract: PURPOSE:To obtain a resist image of high resolution at a high speed by carrying out primary exposure and secondary exposure in an atmosphere of necessary gas and forming a pattern latent image. CONSTITUTION:The space 6 between an exposure mask 3 and photosensitive resist 2 on a printed board 1 is put in a nonactive atmosphere of nitrogen gas, etc., and the primary exposure using parallel energy rays such as ultraviolet rays is carried out to set only the surface part of the resist 2 in conformity with the pattern of the mask 3. Then, the secondary exposure using parallel rays is performed while the space 6 is placed in an active gas atmosphere of oxygen gas, etc., to set up to the bottom part of the resist 2. In this case, even if scattered or reflected light strikes the surface of the resist 2 where light should not hit, its setting is hardly caused because of an oxygen impediment. Thus, a resist image is formed at a high speed by the primary exposure and to high resolution by the secondary exposure.
