Title: Surfacial electrometer
Inventor: NIHEI YASUO
IPC: G01R29/12
Filed: 1981-01-30
Abstract: PURPOSE:To arrange so that a surfacial electrical potential may be measured with a simple constitution, by fixing a detection electrode and oscillating a vibrator such as tuning fork provided near the detection electrode. CONSTITUTION:A vibrator 4 is constituted with a conductor and earthed. For instance, a tuning fork is used as a vibrator. Vibration pieces 4a and 4b of the vibrator 4 are arranged opposed to each other as if they hold the sides of a detection electrode 2 facing a charged object 1, and in addition, are arranged in parallel with a line connecting the charged object 1 with the detection electrode 2. If the vibration pieces 4a, 4b are caused to vibrate through the operation to bring them close to or remote from the detection electrode 2, an electrostatic capacity C1 between the charged object 1 and the detection electrode 2 and at the same time, an electrostatic capacity C2, C3 each between the detection electrode a and the vibration pieces 4a, 4b increases or decreases. Then an alternate current signal proportional to the surfacial electric potential V5 of the charged object 1 is obtained on the detection electrode 2. Consequently, under this constitution, it is possible to simplify the structure and reduce the cost involved.

Title: Electric water heater
Inventor: ISHII KATSUMI
IPC: F24H1/18
Filed: 1983-01-28
Abstract: PURPOSE:To prevent the energizing to a heater by on-off action from occurring too frequently by a method wherein a temperature regulating means for day-time power application controls by detecting the hot water storage tank temperature at the location higher than the location, at which a temperature regulating means for midnight power application is arranged. CONSTITUTION:A midnight power heater 4 is connected through a thermostat 6 acting as a temperature regulating means for midnight power application and a time switch 8, which limits energizing hours, to the power supply. A day-time power heater 5 is connected through a thermostat 7, which is arranged at the location higher than the thermostat 6 and acts as a temperature regulating means for day-time power application, to the power supply. Accordingly, even when the thermostat 6 is put into actuation due to the lowering of the temperature at the lower part within the hot water storage tank by supplying hot water through a hot water delivery pipe 3 and feeding cold water through a feed water pipe 2, the thermostat 7 retains its action until the fed water reaches the location of the thermostat 7, the location of the thermostat 7 being higher than that of the thermostat 6. Consequently, the day-time power heater 5 is prevented from being put into action as frequency as every hot water supply operation.

IPC: F01P7/16
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To restrain the deformation of the tip of a rubber spool at the going in/out part of a needle for the rubber spool and prevent the crack generation at the tip of rubber spool by enclosing an elastic body with a specific hardness or fluid body between the rubber spool and the needle. SOLUTION: When a wax 3 expanding/shrinking in response to a temperature is expanded by the increase of the temperature, a needle 5 is pushed out from a rubber spool 4 and a valve element side member 9 is separated from a valve seat side member 8 against a spring 10. In other words, a valve element 6 is separated from a valve seat 7 and a thermostat 1 is opened. While, when the temperature is lowered and the wax 3 is shrunk, the valve element 6 is seated on the valve seat 7 by the spring 10 and the thermostat 1 is closed. In this case, an interference material 12 consisting of an elastic body like a rubber with hardness 10 to 20 or a plastic fluid body is enclosed between the needle 5 and it inside the tip of the rubber spool 4 and the deformation of the tip of the rubber spool 4 is reduced and the generation of a fatigue crack is prevented.

Abstract: PURPOSE:To maintain a symmetric property in the electric charge transfer of an odd number field and an even number field by stopping a vertical transfer pulse in the impressing timing of a photocell reading pulse in one of the fields at the time of a frame storage system driving. CONSTITUTION:A control circuit detects the generation of the photocell reading pulse TG in the even number field at the time of the frame storage system driving and temporarily stops the generation of the vertical transfer pulses V1-V4 in the generation timing. According to this control, at the time of impressing the photocell reading pulse TG (part 4 surrounded by dotted lines in the drawing), there are no vertical transfer pulse V1-V4. Then, in the even number field, immediately after the electric charge is transferred from a photosensitive part 10 to a vertical transfer part 30, the transferred electric charge is not transferred downward but the symmetric property in the electric charge transfer of the odd number field and the even number field is maintained.
