Title: Metallic vapor discharge lamp and projection type display using the same
Inventor: MONJU HIDETO
IPC: H01J61/34
Filed: 1991-11-25
Abstract: PURPOSE:To maintain the light beam utilization efficiency by preventing reaction of metal halide and the arc tube and crystallization thereof without requiring any conventional cladding. CONSTITUTION:The hydroxyl group and hydrogen existent in the atmospheric air is diffused from an outer glass surface of an arc tube 15 kept under a high temperature into the interior thereof, so that the arc tube 15 during lighting thereof causes gradual promotion of crystallization of the glass of the arc tube through reaction thereof with metal halide. A reflection mirror 11 in which the arc tube 15 is accommodated is sealed, or is sealed and vacuumized, or is sealed whereby a gas containing no hydroxyl group or hydrogen is sealed thereinto. As a result, hydroxyl group or hydrogen is somewhat existent, or-not existent whatsoever around the arc tube 15, so that diffusion of hydroxyl group or hydrogen from the outer glass surface into the interior thereof less occurs, or almost not occurs. Thus, the crystallization of the arc tube 15 is kept low.

Title: Level adjusting circuit for infrared sensor
Inventor: IIDA KIYOSHI
IPC: G01J5/22
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a level adjusting circuit of infrared sensor, wherein level adjustment is effective even to such signal, which is fast and requires level adjustment for every pixel like infrared sensor signal. SOLUTION: Level adjustment value data are written in a memory 8 in advance, for every bolometer 1a (pixel) of an infrared ray sensor 1, and a digital control current source 3 generates level adjustment current according to the level adjustment value data. When a read-out circuit 2 reads out the change in resistance value Rb of the bolometer 1a, level adjustment of the bolometer 1a is performed with the level adjustment current. Since the level adjustment is performed in open loop based on the level adjustment value data in the memory 8, the level adjustment of fast signal from the infrared ray sensor 1 is possible.

Title: Large power transmission equipment
Inventor: KAWAI TAKATOSHI
IPC: H03F1/30
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To suppress the fluctuation width of output by measuring the inner temperature of a power amplification means and correcting transmission output fluctuation to be small based on the temperature. SOLUTION: When a power amplification means 11 starts power amplification, temperature difference TD between the inner temperature TAMP of the means 11 an the detected temperature T0 of a temperature detection means 13 increases and is saturated at TDMAX. The temperature difference TD reduces with the stop of the power amplification of the means 11 and finally turns to zero. On the other hand, a temperature difference estimation means 14 models the change of the temperature difference TD or calculates it by an approximate calculation. A temperature difference correction means 15 adds the detected temperature T0 of the means 13 to the temperature difference TD which the means 14 calculates. The inner temperature estimation value temperature TOUT of the means 11 is obtained, and the transmission output of the means is corrected in an output correction means 16.  Then, the fluctuation width of transmission output is reduced so as to provided a superior large power transmission equipment.

Abstract: PURPOSE:To prolong the life of a battery by suppressing power consumption in a disk device of a battery system under the nonselecting state of the disk device by the side of a host. CONSTITUTION:Under a standby mode of nonreceiving of a selecting command from the host side H, an idling mode or a sleeping mode, a CLK selecting signal S is outputted by a microcomputer circuit 11 to a gate array part 10.

Title: Voltage controlled oscillator
Inventor: NAKAMURA TETSUO
IPC: H03B5/32
Filed: 1988-12-09
Abstract: PURPOSE:To easily vary a range by connecting plural oscillators connected in parallel to an oscillation circuit. CONSTITUTION:The voltage controlled oscillator consists of an oscillation circuit 3 connecting to oscillators 4A, 4B in series. Since the oscillators 4A, 4B are connected in parallel resulting in halving a change in the same equivalent reac tance Cv in this way, the frequency variable range, the capture range and the lock range are halved. Thus, even when a current share circuit 1, a variable reactance circuit 2 and the oscillation circuit 3 are integrated into an IC, the frequency variable range, the capture range and the lock range are easily halved by connecting the oscillators 4A, 4B in series. Since. the oscillators 4A, 4B are used as double components, the dispersion in the free-run frequency is halved. Thus, the dispersion in the free-run frequency is improved.

Abstract: PURPOSE:To extremely shorten the data changing time and to improve the working efficiency in the system by separating the data from its executing part and therefore requiring the change of only the changed part of a data part when a test diagnostic program is changed or added. CONSTITUTION:An input means 20 which starts a test reads a data part into an area set previously for the test diagnostic program stored in an external storage 10. Then the entire data part read into the means 20 is converted into such a form that can be processed by a computer via a changing means 30 and then held as it is. Then the data part held by the means 30 is read into a test executing means 40, and a test is carried out by a CPU 60. If the change of data is requested, the data is changed by the means 40 and the second test is carried out. Then the changed data is stored in the storage 10 as long as no problem is confirmed. Thus it is possible to extremely shorten the data changing time and to improve the working efficiency in a test diagnostic system.
