Abstract: PURPOSE: To defrost cooling coils by the quantity of heat possessed by the gas to be dehumidified and make long-term continuous operation possible without stopping a device for defrosting by performing precooling and dehumidifying by cooling of the gas to be dehumidified with two cooling sections.  
     CONSTITUTION: Cooling sections 8A, 8B having separate cooling coils 6A, 6B are provided and are connected to an inlet pipe 2 and an outlet pipe 3 via diverter valves 4A and 4B. The device is so constituted as to feed refrigerant from a condenser 11 to either one of the coils 6A, 6B through a delivery pipe 15 and a branch part 20. For example, a stop valve 21A is opened and 21B is closed to feed the refrigerant to the coil 6A alone. The gas to be dehumidified is passed in order of the pipe 2, a branch pipe 2B, the section 8B under stopping of cooling, a connecting pipe 13, the section 8A under cooling, a branch pipe 3A, and the pipe 3. When the moisture contained frosts and sticks on the coil 6A, the valves 4A, 4B are changed over to pass the gas to be dehumidified in order of the section 8B, 8A, and the refrigerant is fed to the coil 6B.

Title: Partially resonant voltage dropping type power source circuit
Inventor: RI KEIKON
IPC: H02M3/158
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To reduce the power loss of a first switching element by storing a DC voltage in a capacitor for resonance when the first switching element is turned off from a turned-on state and generating a resonance current by making the charged voltage to flow to a coil for resonance through a second switching element before the first switching element is turned on from a turned- off state. SOLUTION: When a field effect transistor FFT11 of a voltage dropping section 200 is turned off, an electric current I1 is prevented from flowing to the transistor FFT11, but is made to flow to a capacitor C15 for resonance so as to charge the capacitor C15. When, in addition, the field effect transistor FFT13 of a partial, resonance section 300 is turned on, the charged power of the capacitor C15 generates a resonance current flowing to a coil L13 for resonance. Therefore, the power loss which occurs when the switching element is turned on and off can be reduced.

Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent the falsification of a bankbook by replacing an impression seal by laminating an easily extending or collapsing cover layer having see- through properties on a seal body, and printing different numbers on respective seal bodies. SOLUTION: An easily extending or collapsing cover layer 5 having see- through properties is laminated on the falsification preventive seal 1. A number 7 is printed on a surface of an adhesive layer 6 exposed in the state that a release sheet 8 of the seal 1 is partly released. In the falsification preventive bankbook using the seal 1, at the time of intending to release a seal body 2, the layer 5 is extended and deformed or collapsed, and hence it cannot be released in a recycling state. Since different numbers 7 are printed on respective bodies 2, in the case of intending to replace to stick it to a new seal body 2, the number 7 cannot be brought into coincidence with a transfer number transferred to the bankbook.

Filed: 1995-05-30
Abstract: PURPOSE: To detect displacement information with high accuracy by a method wherein an irregularity in quantities of light between a plurality of pattern formation parts is monitored so as to be detected according to the difference between the quantities of light. CONSTITUTION: A luminous flux from a light source LGT is shone at a scale D which is moved relatively. Illumination light to an origin track TZ generates a light and shade pattern in a space, and transmitted light from an amplitude grating GTZ for the origin is received by a photodetector SZ. Then, whenever the light is transmitted through the origin, a pulse- shaped analog signal is outputted via a signal processing circuit, and the passage of the origin in the scale D is detected. From the illumination light onto absolute code pattern tracks Tu , Tv , Tw , the transmitted light is projected intermittently on photodetectors Su , Sv , Sw by a direct-acting part D, and an absolute position is specified by the signal processing circuit on the basis of their outputs.  The illumination light is transmitted also through tracks Tref1 Tref2 for monitoring of a quantity of light, and photodetectors Sref1 , Sref2 output quantity-of-light signals. Then, the signal level of the photodetectors Sref1 (or Sref2 ) is subtracted from signal levels of the photodetectors Su , Sv (or Sw , Sz ) so as to be corrected by the processing circuit before the signals are processed.

Filed: 1985-06-19
Abstract: PURPOSE:To dissolve the irregularity of documents caused by the drooping of documents by making both sides of documents parallel to the conveyance direction higher or lower than the center just in front of a stacker. CONSTITUTION:A circular-arc-like sheet guide 8, with the inner periphery of the circular arc facing upward, is arranged between a stacker 1 and a sheet guide 4.

IPC: H02M7/48
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent the break-down of the switching element of a PWM inverter, by equipping a protector with an AND circuit which protects the PWM inverter from overvoltage by short-circuiting the output of the PWM inverter when the input DC voltage of the rectangular inverter drops under the set voltage. SOLUTION: A self-exciting SVC operation signal VO is inputted into an AND circuit 11, and the DC Vb voltage on the input side of a rectangular inverter is compared with the set voltage Vr by a comparator 10. Then, when the DC voltage Vb drops under the set voltage Vr, switching elements Sa and Sc, or Sb and Sd are made electrically conductive, judging that overvoltage is applied to the PWM inverter 2 by short circuit failure on the DC side. Then, the failure current flowing from the system side to the PWM inverter 2 flows to the terminals B and the terminal A and short-circuits the output of the PWM inverter. Hereby, the break-down of the switching element is prevented without applying overvoltage to the PWM inverter 2.
