Title: Operation display device for solenoid relay
Inventor: TSUJI HIDEAKI
IPC: H01H50/08
Filed: 1989-04-14
Abstract: PURPOSE:To improve reliability an productivity an reduce failure by dividing an exciter coil into a primary and a secondary coils, connecting the primary and secondary coils in series, and connecting an operation display circuit having a light emitting element to the secondary coil in parallel. CONSTITUTION:When a dc voltage is applied between coil terminals 25a and 25b to excite a primary coil 13 and a secondary coil 14, a movable iron piece 5 is attracted, a normally closed contact point is opened, and a normally opened contact point is closed. At the same time, a divided voltage proportionate to the impedance ratio of the coils 13 to 14 is applied to an operation display circuit 10. This causes a light emitting diode to emit light to verify that a solenoid relay is in operation. If the primary coil 13 breaks, current does not flow through the primary coil 12 nor through the secondary coil 14, the solenoid relay does not operate, and the light emitting diode does not emit light. Thus, operation display according to the operation of the solenoid relay is performed.

IPC: B01D46/42
Filed: 1988-04-20
Abstract: PURPOSE:To prevent access of a lighted match or burning ash to a filter and to improve safety by providing an aluminum sheet pierced with many narrow holes behind an ash tray and above the filter. CONSTITUTION:A fan 42 fixed to a motor 41 is rotated, when a switch is turned on. The smoke from a cigarette placed on a groove 49 is sucked from a suction port 16, passed through the narrow hole 20 of the aluminum sheet 19, filtered by a filter 25, passed through a wire mesh 51, and discharged from an exhaust port 43 by the fan 42. In this case, since the aluminum sheet 19 pieced with many holes 20 is provided above the filter 25, the flame generated from the burning of a match, paper, etc., in the ash tray is sucked from the suction port 16. However, the heat is absorbed by the aluminum sheet 19, hence the filter 25 is not burned or melted, and safety is surely enhanced.

Title: Semiconductor light-emitting and light-receiving device
Inventor: TAKAHASHI KAZUHISA
IPC: H01S5/026
Filed: 1983-05-30
Abstract: PURPOSE:To bring a light-emitting element and a light-receiving element arranged close to each other sufficiently, and to obtain large photocurrents in the light-receiving element without increasing the area of light reception by forming the light-emitting element and the light-receiving element for monitoring an optical output from the light-emitting element in the same chip. CONSTITUTION:A P-N junction 14 for a LD emits light and laser-oscillates by positive- pressure biassing an upper electrode 9 for the LD to a lower common electrode 8. Since an N type InGaAsP layer 3 is formed uniformly extending over the whole chip to a stratiform shape, light emitted from the P-N junction 14 for the LD is also propagated over a P-N junction 15 for a PD, totally reflected by a by-end surface 12 and projected to the outside from a main end surface 11. On the other hand, the P-N junction 15 for the PD functions as the PD by negative-pressure biassing an upper electrode 10 for the PD to the lower common electrode 8. Consequently, when LD oscillated beams are propagated under the P-N junction 15 for the PD, one part is absorbed, and photocurrents are generated in the P-N junction 15 for the PD. Since laser beams are propagated in the N type InGaAsP layer 3 held by an N type InP leyer 2 and an N type InP layer 4, they are combined with the P-N junction 15 for the PD by approximately 100%.

Title: Level displaying device for digital audio signal
IPC: H03G1/00
Filed: 1992-03-25
Abstract: PURPOSE:To provide a displaying device which shows an output level and a reference level of a mixing console. CONSTITUTION:A bar graph meter 28 to 100 segments turns on the 20th lower segment to show a reference level set with the data having level 0 and also shows the data 0 with lighting of 1 segment. When the output level shows -30dB, the lower 10 segments are all turned on. Then all segments up to the 30th segment are turned on with the output level equal to -10dB. When the output level exceeds the reference level, the reference level is also turned on. Therefore it is allowed to display only the segment of the reference level with inversion and with no lighting in order to facilitate the identification of the reference level. In such a constitution, both the output and reference levels can be shown by a single meter 28 and therefore the identification of both levels is facilitated and the hardware structure is simplified.

Title: Method and apparatus for controlling supply air temperature
Inventor: EGUCHI KATSUZO
IPC: F24F11/02
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To heat air conditioning object stratum efficiently and shorten a rise time of space heating. SOLUTION: Means 8 for setting a supply air temperature difference is provided, by which a constant temperature difference (a small temperature difference) Δt (e.g. 10 deg.C) is given to a control arithmetic unit 3-1. The control arithmetic unit 3-1 compares a room temperature T with a room temperature preset value Tset and judges that space heating is rising up if T<Tset. During starting up of the space heating, a supply air temperature preset value Tsaset is obtained by addition of the constant temperature difference Δt to the room temperature T at that time, and a supply air temperature Tsa is controlled so as to be equal to the Tsaset. During the starting up of the space heating, air volume can be increased. Thereby supply calories to great indoor space 1 are increased, and a starting up time of the space heating is shortened.
