Title: Band-pass filter
Inventor: SAITOU MITSUO
IPC: H01P1/205
Filed: 1982-07-15
Abstract: PURPOSE:To obtain a miniature band-pass filter (BPF) at a low cost, by controlling frequency by controlling the distance between a metallic plate provided at a position distant away by a fixed distance from the open terminal of a coaxial dielectric resonator and said resonator by means of a screw on the market. CONSTITUTION:A metallic plate 20 for frequency control has a contact with the tip of a screw 21 on the market. The screw 21 is turned right or left to vary the space between the plate 20 and a fixed conductor 7 which fixes a three- stage dielectric resonator 9. This variation of space changes the capacity to control the frequency of each resonator. In such a way, the frequency is controlled with combination of the screw 21 and the plate 20. Thus, a miniature PFF is realized with a low cost.

Title: Calibration method of sensor in earthquake observing equipment
Inventor: SETO YUKIO
IPC: G01V1/00
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To enable continuously detecting generation of an earthquake at the time of calibration of a sensor, by a method wherein, after residual channels except a specified channel in an earthquake measuring system of multichannels are calibrated, calibration of the channel which is not yet calibrated is performed. SOLUTION: According to stored program, a CPU 40 excepts a specified channel, e.g. an N channel, and calibrates sensors 1-3 about the residual A-C channels. In a time band after the calibration, the CPU 40 operate an oscillator 5, turns on a changeover switch 2n on at the same time, and calibrates only the sensor (n) of the N channel. When an earthquake is generated during calibration of the A-C channels except the N channel, the earthquake can be detected with the N channel. When an earthquake signal is transmitted to the CPU 40 through amplifiers 61-6n, an A/D converter 70 and a data line 80, the calibration of a channel during calibration is interrupted, and all channels are transferred to a recording mode of earthquake wave.

IPC: G03B27/32
Filed: 1981-08-08
Abstract: PURPOSE:To inhibit a development end warning means from operating when  next exposure is performed while an exposed film is developed with regard to  the recording device of a processor camera, etc., which uses a long-sized film  and performs exposure, development, fixture, drying, etc., consequtively and  automatically. CONSTITUTION:When photography is restarted before a development end detector 51 outputs a development end signal, a flip-flop 59 is reset by the signal of an original detection switch 6 to inhibit an alarm device from operating even when development in process at this time ends. With a development start command switch 52, flip-flops 58 and 59 are set to start next development and when the development end signal from said detector 51 is outputted, the alarm operates to let an operator know the ending of the development. Consequently, it is not necessary to interrupt the operation and stop the alarm when development is carried out one after another as mentioned above.

Title: Rotary machine
Inventor: INOUE TOMOHIRO
IPC: H02K9/08
Filed: 1977-10-20
Abstract: PURPOSE: To prevent the corrosion owing to corrosive gas by internally encapsulating nitrogen gas or chemically treated clean air and performing axis sealing as in hydrogen cooling.  
     CONSTITUTION: The nitrogen gas from a steel gas cylinder 12 is pressure-reduced to constant pressure by a pressure regulating valve 13 and adjusted to specified pressure by an automatic pressure regulator 14, then fills the inner part of a rotary  machine through an air inlet valve 4. It also fills the sealing oil for axis sealing or  sealing air supplied from a feed pipe in a mechanical sealing chamber 7 and raises  this pressure higher than the nitrogen gas pressure of the rotary machine. In other words, it always sets the intra-machine nitrogen gas higher than atmospheric pressure. As a result, ambient corrosive gas does not penetrate into the machine, thus preventing the internal corrosion of the rotary machine
