Title: Copying system
Inventor: NISHI KENICHI
IPC: G03G21/02
Filed: 1980-07-31
Abstract: PURPOSE:To obtain a copying system which permits copying within set sheet numbers by putting copying machines mounted with counters into an active state as far as the count values of the counters which are freely attachable and detachable and make down counting are not zero. CONSTITUTION:Counters 1 which are held in respective divisions and are freely attachable and detachable to and from desired copying machines 4a- make down counting from set sheet numbers at every copying and the permissible remaining sheet numbers are displayed in their display parts 2. As far as the count values thereof go zero, the count value read signal transmitting and receiving part 6 of the copying machine 4 mounted with this counter 1 outputs a high level signal and a high level signal for copying permission is applied from the AND circuit 13 of a control part 8 to the copying machine 4, whereby copying is accomplished. Hence, the copying system permitting copying within the set sheet numbers is obtained.

Title: Microwave liquid sensor
Inventor: OMATOI NAOYUKI
IPC: G01F23/284
Filed: 1994-04-07
Abstract: PURPOSE:To detect the liquid level reliably through a simple structure while avoiding trouble due to incomplete fixing or the influence of static electricity by ensuring a margin at the time of fixing through the use of a slightly longer wavelength and measuring the liquid level without judging by the ground potential as reference. CONSTITUTION:An oscillation Gunn diode standing in a cavity resonator 1 is fed with power from a power supply 3 to oscillate microwave having wavelength of about 12.5mm and the potential thereof is measured by means of a detection diode 4 of an adjacent waveguide 6. Radio wave radiated from the waveguide 6 is transmitted through a tube 7 disposed immediately in front thereof to radio wave absorber 8. When a liquid 9 ascends in the tube 7 to cover the waveguide 6 immediately in front thereof, the radio wave is reflected thereon and interferes with a traveling wave to generate a high standing wave. Presence of the liquid 9 is determined, along with the level thereof, by detecting the standing wave.

Title: Pulse stretching circuit for angle error detection circuit
Inventor: SAKATA HIDEO
IPC: H03K5/04
Filed: 1981-07-07
Abstract: PURPOSE:To provide an angle error detection circuit with better characteristics dispensing with a compensation circuit by improving the pulse stretch linearity with a diode inserted into a feedback circuit of an arithmetic amplifier. CONSTITUTION:The output of an arithmetic amplifier 17 of a pulse stretch circuit composing an angle error detection circuit is fed back to the inversion input through a first diode 19b while done so through a second diode 19c connected to a resistance 16c.

Title: Apparatus for measuring pulse-like analog voltage signal
Inventor: KODAMA EIJI
IPC: H03K7/02
Filed: 1986-05-12
Abstract: PURPOSE:To always detect the voltage value of a pulse-like analog voltage signal at an optimum time while avoiding the transitional effect of a wave form, by making the time interval from the front edge of the pulse-like signal to the point of time when voltage is detected variable with the change in the time width thereof. CONSTITUTION:A time width detection means consists of an oscillation circuit 9 generating a clock pulse PC, an AND gate 7 permitting the pulse PC to pass when inputting a pulse-like analogue voltage signal (a) and a binary counter 11 calculating the pulse PC from the gate 7 and inputs the signal (a) to detect the time width thereof. A subtraction counter 13 stores the count value counted by the counter 11 in a state shifted to the left by one bit so as to store the half of said count value and subtracts the clock pulse PC due to the next signal (a) from the half of the count value when the next signal (a) arrives and outputs a pulse showing a sample/holding instruction when the subtraction value comes to zero. By this method, because instantaneous voltage can be sampled at the point of time corresponding to about 50% of the pulse time width regardless of the pulse time width or cycle, stable detection can be performed.
