Patent JP-H06315173-A (JP)
Title: Transmission controller
Inventor: YAMAGUCHI NAOYUKI
IPC: H04Q3/42
Filed: 1993-04-30
Abstract: PURPOSE:To compulsorily lower the noise level at the time of transmitting a control signal by measuring reception power after a control signal is eliminated, not imparting attenuation to a reception signal when power is large and imparting attenuation when power is small. CONSTITUTION:A power measuring means measures the power of an input signal. Set values P1 and P2 in two comparators to be the components of a gain setting means and signal power are compared, and which one of three ranges of >=P2, <=P1 and between P1 and P2 signal power is discriminated. When signal power is >=P2, gain G0 (gain 1) is outputted, when signal power is <=P1, gain G1 (smaller than gain 1) is outputted and when signal power is between P1 and P2, gain proportional to signal power is outputted. A variable amplifier means amplifies an input signal by the gain determined by the gain setting means. A memory such as ROM, etc., is used as the setting means.

IPC: H05B6/72
Filed: 1977-10-17
Abstract: PURPOSE: To improve the uniformity of heating and the radiative efficiency of high frequency, by horizontally radiating the electric field while turning the antenna.  
     CONSTITUTION: An L-shaped antenna between a waveguide 2 and heating chamber 4, its vertical section 10 having a length a of about integral times 1/4 of the wavelength and its horizontal section 11 having a length b of about 1/2 of wavelength, is  revolved by a motor 5. Thus the vertical section 10 predominantly radiates waves to  the arrow 12 direction as a dipole antenna and the horizontal section 11 radiates  waves to the arrow 13 direction. Being distant from the heating chamber wall 7 by  about 1/4 of the wavelength, the ghost wave on the wall 7 and the wave of the  horizontal section 11 meet each other in the heating chamber 4. In addition, the  rotation of the antenna 3 simultaneously excites the vertical and horizontal electric  fields and improves the uniformity of the high frequency heating

Title: Paper sheet accumulating device
Inventor: YASUDA TOSHIHIKO
IPC: B65H31/26
Filed: 1987-05-25
Abstract: PURPOSE:To make it possible to satisfactorily accumulate paper sheets into an accumulating box by automatically retracting a retaining lever which has been projected from a guide in association with an instruction from a control circuit when such a condition that paper sheets cannot be accumulated in the storage box, is detected. CONSTITUTION:Postal matters P extracted from a supply section 1 are accumulated in an accumulating box 5 through a conveying passage 3, and the length of each postal matter is measured by a control circuit 20 in association with turn-on and-off signals from a photo-cell 8 on the way of conveyance, and is stored in memory. Then, the control circuit 20 turns off a solenoid 6 when the postal matter P passes through a photocell 9, and accordingly, a retaining lever 7 is retracted from a guide 4. Further, the solenoid 6 is turned on in accordance with the length stored in memory so as to project the retaining lever 7 in order to push the postal matter P into an accumulating box 5, and then the postal matters P are accumulated in order. Further, when a dark signal from a photocell 9 is lasted more than the passing time of the postal matter P, the solenoid 6 is turned off so as to retract the retaining lever 7, and this retracted condition is sustained until a bright signal is issued. Thus, it is possible to prevent the accumulating condition from being deteriorated.

Filed: 1982-07-21
Abstract: PURPOSE:To promote responsiveness of a polarographic type oxygen sensor, by attaching a porous insulating material to the periphery of a cathode's top section where the cathode is brought into contact with a diaphragm of the oxygen sensor. CONSTITUTION:A cathode 4 of a polarographic type oxygen sensor 10 is supported with an insulation holding material 30 so that the peripheral side of the cathode 4 may be exposed up to a prescribed height (for example, 1mm.) above its end where the cathode 4 is brought into contact with a diaphragm 8.

Abstract: PURPOSE:To shorten the retrieval and read time of a file by arranging plural information recording parts in the data area of a recording medium and moving a head to one of the information recording parts according to the position of the head. CONSTITUTION:The data area 1 is formed on the recording medium 11, and a block 2 for storing data and information recording parts 3a and 3b where control information for controlling the block 2 is recorded at the head and tail parts are arranged in the data area 1.
