Title: Ventilator
Inventor: WAKAI MASAO
IPC: F24F7/007
Filed: 1987-01-20
Abstract: PURPOSE:To enhance the effect of ventilation fan by maintaining the pressure inside a room at a constant level by providing an air supply fan having a differential pressure switch which is actuated when the pressure difference between the outdoor and indoor reaches a certain level. CONSTITUTION:When a ventilation fan 2 disposed in a ventilation opening 3 in a house 1 is operated, a pressure difference is generated between the indoor 10 and outdoor 11. Said pressure difference is detected by a differential pressure switch 7 in sensor ports 9, 8 across the indoor and outdoor, and the switch 7 is actuated when the pressure difference became greater than a predetermined level at which effective ventilation can be expected. Then, an air supply fan 4 is operated. When the pressure difference becomes smaller than the predetermined level, the air supply fan 4 is stopped, but, because of the fan's inertia rotation, the pressure difference is maintained at a level slightly lower than the predetermined level. By the operation, stoppage and inertia rotation of the air supply fan 4, the pressure difference between the indoor and outdoor can be maintained near to the predetermined level. Therefore, ventilation can be effectively performed by the ventilation fan 2.

Title: Integration time variable type dual slope integrator
Inventor: ISHIGURO KENZOU
IPC: G06G7/18
Filed: 1983-01-26
Abstract: PURPOSE:To ensure more flexible measurement compared with a conventional case where the integration time is fixed by varying the integration time and at the same time correcting the discharge time in response to the integration time. CONSTITUTION:A control circuit 16 sets the integration time to a counter 11 for integration time. Then the circuit 16 actuates the counter 11 to close a switch 3. Thus the signal to be measured which is sent from a terminal 1 is applied to an integrator 5. The counter 11 opens the switch 3 when the set integration time elapses and completes the integration of the integrator 5. Then the circuit 16 closes a switch 4 and discharges the integrator 5 with the discharge signal sent from a terminal 2. This discharge time is counted by a counter 7 for discharge time. Here the output of the counter 7 is corrected by a calculator 12 for correction of integration time. Thus it is possible to perform more flexible measurement compared with a conventional case when the integration time is fixed.

Title: Solar cell module
Inventor: HEBINUMA TADASHI
IPC: H01L31/042
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a solar cell module which is used under severe temperature environment. SOLUTION: Interposing members 7a, 7b having flexibility are laid under flat foil metal plates 3a, 3b. The height of upper surfaces of the metal plates 3a, 3b is made to coincide with the height of upper surface of a solar cell element 2. Thereby the metal plates 3a, 3b are connected with the solar cell element 2 without generating a flexed part in a conducting adhesive tape 4. Since the flexed part is not generated in the tape 4, the stress which is generated in the tape 4 when a solar cell package 1 expands and contracts under severe temperature environment disperses in the whole part of the tape 4, and troubles like disconnection can be reduced.
