IPC: H01M4/88
Filed: 1992-08-05
Abstract: PURPOSE:To obtain a porous electrode whose orientational direction in the electrode is arrayed in the thickness direction of the electrode and also in which closed pores are hardly present. CONSTITUTION:An electrode raw material is formed of electrically conductive powder 2a prepared by mixing nylon short fiber 2c having a magnetic pole in the longitudinal direction with, nickel oxide and zirconium oxide stabilized with yttrium, a binder and a solvent 2b, etc. Static magnetic field is impressed on the electrode raw material to form an electrode green sheet 2B of the electrode raw material in the state that the orientational direction of the nylon short 2C is arrayed in the thickness direction of the electrode. After the electrode green sheet 2B was pressed to stick to a solid electrolysis green sheet, the nylon short fiber 2c is eliminated by roasting, thus the porous electrode is produced.

Title: Driving system of magnetic head
Inventor: TAMURA KAZUO
IPC: G11B5/55
Filed: 1981-12-26
Abstract: PURPOSE:To maintain a high and stable moving speed of a magnetic head and to improve the reliability, by turning on and off a power supply of a magnetic head driving source in response to a change of the moving speed of the magnetic head. CONSTITUTION:A rotary shaft 5 of a rotary solenoid 1 starts its revolution after receiving a magnetic head driving signal. Then the pulse-like signals of different intervals are delivered from a photodetecting element 7 in response to the revolving speed of a disk 2, i.e., the moving speed of a magnetic head 4. The pulse-like signal is fed to a frequency dividing circuit 11 to be converted into a signal which shows the time during which the head 4 moves by a prescribed distance. This signal is compared through a comparator 14 with the signal supplied from a timer circuit and showing the reference time. The output of this comparison is led to a switch control circuit 15 to perform an ON/OFF control of a switching circuit 16. As a result, the conduction is controlled to the solenoid 1 to keep the moving speed of the head 4 at a constant level.

Title: Modulation factor meter
Inventor: KUBO SHOICHI
IPC: G01R29/06
Filed: 1985-09-20
Abstract: PURPOSE:To simplify the configuration of a modulation factor measuring circuit and to reduce the cost, by keeping constant the DC level of a detection output in the amplitude modulation signal. CONSTITUTION:A detector 1 detects an amplitude modulation signal. At the point A is outputted a signal of a DC component proportional to the carrier wave level superposed with an AC component of the modulation signal. The output at A is impressed to a variable gain controller 2 to give an output at B, and the gain is controlled by a DC input impressed at a control input terminal E. Here, the output at B is impressed through an integration circuit 3 to the terminal E to keep the DC component at B at a constant value independently of change in the input DC component of the controller 2. This means that the carrier wave level is constant, so that the modulation factor can be determined only by measuring the AC component equivalent to the modulation wave level. Thus, a modulation factor can be read by an indicating device 5, resulting in a simple circuit configuration.

Abstract: PROBLEM TO BE SOLVED: To provide a method and device which improve image quality by correcting a shadow area only with one image and to reduce the adverse effect on the image quality of a sunny area due to the correction and the bluing of a shadow area in handling a color image. SOLUTION: In this device, a gradation image producing means 1 converts each pixel of an original image into values of luminance, saturation and hue and produces a gradation image from luminance values, and an edge-preserved smooth image producing means 3 produces an edge-preserved smooth image from the image. An edge- preserved smooth image luminance gradation converting means 5 divides the image into shadow areas and sunny areas, expands a dynamic range in the shadow areas, and performs conversion without changing luminance in the sunny areas, and meanwhile a high frequency component converting means 6 enhances contrast in the shadow areas. An image synthesizing means 7 unifies these results and produces a luminance- corrected image.  A color correcting means 8 reduces the saturation of pixels in the shadow areas and combines hue and the luminance of the luminance-corrected image to produce a corrected image.

Title: Control channel carrier sense method for tdma-tdd mobile communication system
Inventor: TAGAMI KATSUMI
IPC: H04W74/08
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent disturbances due to interferences, when a mobile station transmits an incoming control channel by deciding a slot corresponding to a minimum electric field intensity among selected electric fields to be a transmission slot of the control channel. SOLUTION: A slot number selection means 4 counts the number of slots, whose levels are below a threshold for a slot of each slot number, regarding an electric field intensity measured value to be inputted. The electric field strength whose level is below the threshold is selected from an input electric field intensity 6, only regarding the electric field of the slot of the selected slot number by the slot number selection means 4. If the electric field strengths whose levels are below the threshold are ST32 and ST42, a slot T32 is decided to be a control channel transmission slot. In this way, it is confirmed that there is no interference with a timing of an incoming control channel reception at control carrier sensing of a base station.
