Title: Etching method and production of thin-film magnetic head
Inventor: SASAKI SATOSHI
IPC: C23F4/00
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To uniformly irradiate a substrate with a beam and to eliminate the variation of the etching quantity within the substrate by largely repetitively turning the substrate in an intra-surface direction in an etching stage using the ion beam. SOLUTION: When the substrate is not turned, the substrate is irradiated with the ion beam 30 approximately parallel with the longs side on the upper surface of a second pole 8. The substrate is repetitively turned and moved back and forth between the position of 180 deg. in a plus direction and a position of 180 deg. in a minus direction. As the substrate is turned, the irradiation direction of the ion beam 30 with second pole 8 changes and the portion which is the shade of the second pole 8 changes accordingly. The direction where the irradiation direction of the ion beam 30 with the second pole 8 is successively varied by repetitively moving the substrate within a specified range. Even if, therefore, the shape of the second pile 8 is asymmetrical on the front side and the rear side, the uniform irradiation with the ion beam 30 is made possible.

Title: Optical recording medium
Inventor: HIBINO JUNICHI
IPC: G11B7/0055
Filed: 1986-07-03
Abstract: PURPOSE:To impart a steric hindrance to a titled medium and to suppress an isomerization reaction by incorporating a long chain to fulgide by using a specific photochromic compd. CONSTITUTION:The photochromic compd. expressed by the formula I (R is an alkyl chain of 5-31C) is used. The steric hindrance is imparted to the compd. and the decrease of a conversion rate by the isomerization is prevented by the long chain of the hydrocarbon incorporated into the compd. Since the fulgide skeleton itself has the higher hydrophilicity than the hydrophilicity of a long chain part, LB film is formed and the thin film having the properties of the fulgide is easily obtd. The easy formation of the independent LB film which is well balanced in the hydrophilic and hydrophobic characteristics and is, therefore, easy to handle is facilitated by the hydrocarbon of preferably 13-23C.

Title: Rotary valve
Inventor: NAKAI OSAMU
IPC: F16K1/226
Filed: 1978-12-16
Abstract: PURPOSE: To effectively prevent leakage attributable to deformation of a valve body and expansion of a valve box, by making a bush which is put on a rorary shaft or a bush casing which is put on the bush movable only in the radial direction.  
     CONSTITUTION: A bush casing 10 is fitted to a bush 9 or a valve box shaft support 5 with a clearance S between them, the clearance S being larger in the direction toward slant cylindrical metal sheets 6, 6 than that in the cross direction and the bush 9 or the bush casing 10 being movable only in the radial direction, while the valve is open. As fluid pressure is applied to the valve body 3 while the valve is closed, the valve body 3 is moved in the working direction of pressure because of the clearance S and also moved, at the same time, in the cross direction because of contact with the sheet, which surely prevents leakage of high pressure fluid.

Title: Synchronizing circuit
Inventor: USUI YUUZOU
IPC: H04L25/40
Filed: 1979-11-30
Abstract: PURPOSE:To make it possible to synchronize a high-speed clock frequency by performing Schmitt triggering by waveform-converting an AND output signal between a signal to be synchronized and a clock pulse and by operating a switch when this signal exceeds a certain value. CONSTITUTION:Data of a signal to be synchronized and a clock pulse are inputted to NAND circuit 9, whose AND output signal is inputted to the waveform converting circuit composed of resistance R and capacitor C to prolong the rise time of the AND output signal. The waveform-converted signal is inputted to Schmitt trigger circuit 6. When the output of trigger circuit 6 reaches a prescribed level, switching transistor 10 connected in parallel to resistance R is made operated to short-circuit resistance R. Therefore, the voltage at point A rises suddenly and trigger circuit 6 turns the circuit off. Thus, the existence of data is judged securely, so that a high- speed clock frequency can be synchronized.

Title: Multiple frequency band mobile communication station
Inventor: GRAYSON MARK
IPC: H04W84/06
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce the power of a mobile station required for retrieving the coverage area of a ground base station or an orbit satellite station. SOLUTION: A CPU 13 gives a command to a DSP 12 for retrieving three frequencies at maximum in a TDMA frame when retrieving. The CPU 13 sequentially gives the three frequencies to be checked to the DSP 12 to retrieve all ground frequency bands. This cycle continues under the condition that there is a detection signal with power enough to be strong to set up an AGC in an RF stage 10 until an RSSI level is received. The CPU 13 arranges the frequencies in the order of higher RSSI levels. When the level is higher than a threshold level, the CPU 13 gives a command to the DSP 12 to be synchronous with the channel. The DSP 12 tries to decode a broadcast message by synchronizing its operation with respect to accurate transmission timing, and a frequency at first and then tries to decode a synchronization burst. When the trial is successful, the CPU 13 registers it, the mobile station completes the operation at the outside of its coverage and 'stays' in the found-out channel.

IPC: H04N7/24
Filed: 1993-06-25
Abstract: PURPOSE: To improve a virtual real environment by leaving a space so that a form is viewed as a moving picture and displaying it as a changing texture. CONSTITUTION: The data structure of a display object, which is stored in a memory 120, is allocated to algebraic information on the display object containing a polygon pointing an area to which a first texture of a texture memory 126 is loaded. When the position and the orientation of the polygon are assumed to be within the range of the view of an observer, a plotting pipeline 102 plots the first texture of the moving picture on the polygon by the same method as a conventional texture. A potting control processing block 104 automatically transfers a next texture map in a moving picture string to the same area of the texture memory 126 from an execution time data base 110 or a storage unit 126a and the polygon is plotted by the respective textures. Thus, the smooth moving picture is supplied by selecting speed at which the textures are transferred to the texture memory 126.
