Title: Multi-track magnetic recording and reproducing device
Inventor: WATAYA MASAFUMI
IPC: G11B27/36
Filed: 1983-08-31
Abstract: PURPOSE:To understand an accurate level of a compound signal by selecting properly whether the signal supplied to a level meter is limited only to a channel input of a compound signal added with a signal of another channel by means of a track/channel changeover switch. CONSTITUTION:An input changeover switch 6 has a pair of contacts which are connected to a pair of mixer circuits 13 and 14 respectively in addition to a contact connected to a corresponding input amplifier circuit 21 or 24. A switch 15 or 16 is closed to add together input signals of an optional channel, and this added signal can be supplied equally to an input selection switch 6 of each channel. While level meters 41-44 of each channel are connected between an input signal line 5 and an output signal line 9 via a changeover switch 17. These level meters are switched to a contact 17t of the track side to display the signal level of a track and to a contact 17c of the channel side to display the signal level of a channel respectively.

Title: Electric motorcar power supply controller
Inventor: IIDA KEIICHI
IPC: H01G11/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To charge it to voltage larger than battery voltage with little power loss at regeneration, in an electric motorcar power supply controller which is equipped with a large-capacity capacitor in addition to a battery, and mainly charges the capacitor at the time of regeneration, and supplies a vehicle driving motor with power from that capacitor or battery at the time excluding the time of regeneration. SOLUTION: At the time of regeneration, a capacitor 1 is charged directly with a regenerated currents through an exclusive wiring 12. A unidirectional converter 8 is stepped up or stepped down from the side of a capacitor 1 to the side of a battery 4, which obviates the necessity to put the capacitor charge voltage to battery voltage or under. When a regenerated current gets over a specified value, the unidirectional converter is operated to turn the amount of its excess to the charge of the battery. By doing it so, the power loss at the capacitor does not become large. In the case of supplying it from the capacitor 1, the power supply is made by stepping up or stepping down the voltage of the capacitor so that the output voltage of the unidirectional converter may amount to battery voltage or thereabouts.

IPC: G01L19/06
Filed: 1982-09-16
Abstract: PURPOSE:To obtain a structure which is excellent in trailing property and can be formed like a thin film, by using an amorphous metal for a diaphragm, in a pressure and differential pressure transmitting device having a diaphragm type diaphragm. CONSTITUTION:A flange 2 is placed so as to cover a durable body 1 which is endurable enough against pressure, and when a liquid to be measured of pressure P0 is introduced from a pressure inlet port 3 provided on the flange 2, it is transferred to a liquid separating diaphragm 4.

Title: Driving device for inter-line transfer type ccd
Inventor: TAKATSU NORIHIKO
IPC: H04N5/335
Filed: 1985-07-22
Abstract: PURPOSE:To provide a solid-state image pickup device itself with a shutter function without using an OFCG (overflow control gate) by using a period from a point of time of unnecessary charges are drained from a photodetecting part to a point time of optical signal charges are transferred to a vertical transferring part as a shutter time. CONSTITUTION:When a voltage -Vg is applied to a polysilicone electrode constituting a sensor gate, electrons are driven from the interface between a P-type silicon substrate 10 and a silicone oxide SiO2 9 into the inside (to the right-hand direction in the figure) of the substrate 10, and holes are accumulated at the interface-part instead of the electrons. The state of accumulating type is thus generated by impressing the sensor gate voltage -Vg, by which the electrons of signal charge can be completely drained to the substrate side without draining them to the OFD. This means that a state in which no signal charges exist in the photodetecting part can be generated by controlling the sensor gate voltage to be -Vg. As a result, the solid-state image pickup element itself can have the shutter function.
