Title: Electron multiplier tube
Inventor: KUSHIMA HIROYUKI
IPC: H01J43/22
Filed: 1994-06-06
Abstract: PURPOSE:To provide an electron multiplier tube which involves less dispersion in the multiplication factor. CONSTITUTION:A sphere 27 is fixed while pinched by the upper electrode plate and lower electrode plate of dinodes 24, and therefore, there is no risk of the sphere 27 being set off from a through hole when the dinodes 24 are to be stacked. This permits keeping uniformly the dinode spacing in each layer, and there is no problem such that the multiplication factor gain disperses owing to the unevenness of the dinode spacing. In particular, it is not required to lay spheres 27 in line on dinode 24 when a plurality of dinodes 24 are to be stacked, as required according to the conventional techniques, to lead to facilitation of the manufacture.

Patent JP-H07332772-A (JP)
Title: Air conditioner
Inventor: SHIRAKAWA SHOICHIRO
IPC: F25B1/00
Filed: 1994-06-06
Abstract: PURPOSE:To improve comfortableness by allowing the opening of a flow regulating valve to satisfactorily follow up the rise of an operating frequency after release control is finished, thereby eliminating the insufficient trend of refrigerant return amount to a compressor, and reducing the number of times of the release control while preventing the abrupt rise or abnormal rise (overshoot) of discharge refrigerant temperature. CONSTITUTION:The opening of a flow regulating valve 4 is so controlled that the superheat degree SH of refrigerant in an evaporator becomes constant. When the discharge refrigerant temperature Td of a compressor 1 becomes a set value T2 or higher, an operating frequency F is reduced until the Td is lowered to the value T1 (<T2) or less and the opening Q of the valve 4 is controlled in response to the temperature Td. On the other hand, in the case of starting the release control, the opening Q of the valve 4 is stored. When the release control is finished, the opening of the valve 4 is set to the stored opening, and the state is maintained for a predetermined time t1.

Title: Video signal transmission equipment
Inventor: MIZUNO SAKUYUKI
IPC: H04N19/169
Filed: 1988-05-23
Abstract: PURPOSE:To prevent the occurrence of the same phase shift on a horizontal scanning line by comparing the phase of a horizontal synchronizing signal and the phase of a sampling clock and shifting the clock by a half phase when the phase difference obtained by the above-mentioned comparison becomes an integer-times the frequency of a vertical synchronizing signal. CONSTITUTION:A counter 22 counts sampling clocks from an oscillator 8 and outputs the counted value to a latch circuit 23 when an initial value is given to the counter 22, and the horizontal synchronizing signal is inputted to the counter 22. The circuit 23 D/A-converts the counted value and gives the D/A-converted counted value to the oscillator 8. Consequently, while the oscillation frequency of the oscillator 8 is decreased, and the phase of the clock is delayed by the half phase when the counted value of the clock increases for the initial value, and when the output of a circuit 24 becomes smaller, the phase of the clock is advanced by the half phase when the output of the circuit 24 becomes larger. Further, control to shift the clock for the half phase is executed when the same phase shift occurs repeatedly on the horizontal scanning line in a period which is integer-times a vertical synchronizing period. Thus, it can be prevented that the same phase shift occurs repeatedly on the horizontal scanning line.

Title: Sensor system calibrating method and photographic film carrier
Inventor: SETO YASUHIRO
IPC: G03B27/46
Filed: 1991-05-29
Abstract: PURPOSE:To maintain an invariably optimum adjustment state by automating initial adjustments and periodic adjustments of respective sensor systems. CONSTITUTION:The quantity of light emission is adjusted so that the output value of a photodetection side does not exceed a specific range. Threshold values with which the output values of a film presence/absence sensor 272 and a tape detection sensor 270 are compared are varied and the sensor systems are adjusted periodically by using a known reference film, etc. Further, a reference film whose high/low density border is clear is conveyed to detect high/low density borders, sensor by sensor, and the difference between the distance of the conveyance of the reference film from a detection point to a reference position and a previously set distance is corrected by being substituted with the number of pulses of a pulse motor to recognize an accurate position. If the array of image detection sensors 264 is inclined owing to an error in fitting accuracy, the detected value is shifted corresponding to the corrected error and inputted to a data table. Consequently, apparently four sensors are arrayed in the width direction of a photographic film and an image frame edge can accurately be detected.

Abstract: PURPOSE:To prevent a transformer from irregularly magnetizing by continuously integrating the additional winding voltage of a period while diodes connected in parallel are ON, and limiting the upper and lower limits of a reference voltage valve so that the output of the integrator always becomes zero. CONSTITUTION:An additional winding 23 is provided in a filter reactor 2, and the voltage time product of the period while diodes 10, 11 connected in parallel with switching elements 5, 6 of the induced voltage of the winding 23 are ON is proportional to the set and reset magnetic fluxes of a transformer 3. Accordingly, the voltage of the winding 23 during the period while the diodes 10, 11 are ON is continuously integrated by an integrator provided in a correcting circuit 12, thereby controlling the upper and lower limits of the reference voltage wave so that the output of the integrator becomes always zero. In this manner, the set and reset magnetic fluxes of the transformer can be equalized, thereby preventing the irregular magnetization of the transformer.
