Patent JP-H01284062-A (JP)
Title: Communication equipment
Inventor: WATABE MITSUSUKE
IPC: H04Q3/58
Filed: 1988-05-11
Abstract: PURPOSE:To transfer the talking state to data communication with a simple operation by controlling the DC loop state at a telephone terminal of a data communication equipment in response to the communication state similar to a telephone set attached to the data communication equipment. CONSTITUTION:A channel line 3 connecting to a master set is switched between a hook switch 11 and a DC loop detection circuit 16 via relays 15a, 15b. When the hook switch 11 hooks off, an off-hook code is sent to the master set via a control line 4 and a DC loop forming circuit 17 forms a loop of a DC loop forming line 7. In case of starting facsimile communication during talking, the start key of a facsimile equipment is simply depressed. When the facsimile communication is started, since a DC loop detection circuit 18 does not detect any DC loop, the two relays 15a, 15b are switched to connect the speech line 3 to the speech line 6 to the facsimile equipment 8 via the DC loop detection circuit 16.

IPC: H01L21/3065
Filed: 1993-05-14
Abstract: PURPOSE:To suppress fluctuation in the resistance due to the machining of electrode being connected with a thin film resistor. CONSTITUTION:A Ti film 3 for channel stopper is formed on the surface including a thin film resistor 2 and an Au film 4 for electrode wiring is deposited thereon. It is then patterned by ion milling and the Ti film 3 is subjected to wet etching.

Title: Controllable equipment for damping force of air suspension of automobile
Inventor: WASHIZU SHIYOUICHI
IPC: F16F9/08
Filed: 1982-06-30
Abstract: PURPOSE:To obtain a damping force appropriate to the conditions of road surface and driving, by altering the damping force of an air suspension depending on the conditions of road surface and driving. CONSTITUTION:When the four-wheel-drive signal of a driving method sensor 6 and the low-speed signal LS of a vehicle speed sensor 7 are simultaneously generated, a vehicle is judged being driven on a bad road and an output signal H is produced to operate damping force control solenoids S to shut orifices. In rapid driving as indicated by the high-speed signal HS of the vehicle speed sensor 7, the output signal H is produced as well as in the bad-road driving, whatever the signal of the driving method sensor 6 is, to operate the solenoids S to shut the orifices. The damping force of a damper is thus heightened in the bad-road driving and in the rapid driving to prevent the damper from thrusting the vehicle body upwards in the bad-road driving, improve the property of passing through the bad road and promote the stability of the rapid driving.

Title: Low pressure electric discharge lamp
Inventor: NAKAI KATSUMASA
IPC: H01J61/067
Filed: 1982-06-29
Abstract: PURPOSE:To provide a small low pressure electric discharge lamp which is designed to be small but highly efficient, has a good charcteristic and a long life, and has an electrode structure and conveniently. CONSTITUTION:A hot spot (H) is formed at the nearest part to a power source (Vs) within the range coated with electrode matter. Electrons flowing in from the pointed end of a sealed wire 4 at the anodic cycle, flows through filaments 6 which are connected to the power source (Vs). Therefore, irrespective of the connection of an external circuit, the filament 6 provided with the hot spot (H) works as an electron path at the anodic cycle, and compensates the reduction of spot temperature. As a result, any adverse effects on the efficiency and the life which conventionally were caused according to the connective condition with the external circuit, don't develop. Consequently, the conventional problem that the characteristic and the life very according to the connective condition with the external circuit is resolved, the best operation is achieved in any connective condition, and a characteristic almost equal to that realized with the usual filament is obtained.

Title: Magnetic-sensor driving system
Inventor: NABESHIMA NORIYUKI
IPC: G01D5/244
Filed: 1989-05-01
Abstract: PURPOSE:To make it possible to decrease the current consumption of a sensor by gradually decreasing the frequency of time-shared driving from the maximum value when there is not output electric signal from the sensor, and maintaining the minimum value after the specified time. CONSTITUTION:A rotary magnet which is detected with a magnetic sensor 1 is attached to the upper end of the rotary shaft of the impeller of a flowmeter, e.g. a water service meter. The frequency F Hz of a clock signal is determined at a sufficiently large frequency so as to detect the maximum rotation of the impeller. When the value of a counter 9 is 0, the intact clock signal is inputted into a one-short multivibrator 6 through a data selector 4. The magnetic sensor 1 is driven at the frequency F Hz of the clock signal. When the movement of the magnet is detected with the magnetic sensor 1 and the electric signal is outputted, the frequency of time-shared driving for supplying working power to the magnetic sensor 1 is made to return to the maximum value temporarily. When there is no output electric signal from the magnetic sensor at the succeeding time period, the frequency of the time-shared driving is gradually decreased. After a specified time, the frequency is maintained at a minimum value, and the current consumption of the sensor can be decreased.
