Title: Digital filter
Inventor: TORII JUNJI
IPC: H03H17/00
Filed: 1988-11-22
Abstract: PURPOSE:To make the title circuit adaptive to various input timing specifications while employing a fixed system clock by detecting a sampling period of an input digital data so as to generate a start signal having a frequency being N times of the sampling frequency and controlling the output timing of the digital data and a synchronizing signal based on a bit input speed. CONSTITUTION:A bit clock BIC whose period is FB is inputted, a word clock SDSY and 16-bit serial data SBI for L and R channels are inputted to an S/P conversion section 11 for each sampling period FW(=1/fs). Thus, a synchronizing signal generating section 20 detects the leading of the word clock SDSY and detects the bit number of the bit clock BIC inputted by one sampling period FW. Then an output word clock WCO having a frequency 8 times the input sampling frequency fs is generated based on the result. The processing by an arithmetic control section 18 and an arithmetic section 12 is synchronized with an internal clock phiM and executed for each trailing of the word clock WCO and 8 sets each of digital data for L and R channels are obtained in one sampling period FW.

Title: Method of finishing disc and device therefor
Inventor: NAKAMURA TAKAO
IPC: B24B21/06
Filed: 1987-11-26
Abstract: PURPOSE:To uniformly finish the outer surface of a disc such as a magnetic disc by maintaining the relative speed between a polishing tape and the disc constant, irrespective of a position to be processed, so as to remove micro projection on the outer surface of the disc uniformly and accurately over the entire surface thereof. CONSTITUTION:A pair of polishing tapes 1 in a machining head is made into press- contact with the front and rear surfaces of a disc 3 such as a magnetic disc or the like on rotation by a contact roller 2 while an abrasive material 9 is fed onto the outer surface of the disc 3. Simultaneously, a slide part of the machining head 12 reciprocates the latter radially of the disc 3 so that micro projections on the front and rear surfaces of the disc 3 are polished and removed by the polishing tapes 1. In this arrangement, the position of the slide part of the machining head is always detected by a linear scale 6 so that a control device 6' controls the rotational speed of a disc rotating motor 7 to maintain the relative speed between the polishing tapes 1 and the disc 3 at a machining point is maintained to be constant. As a result, the dynamic pressure by the polishing material 9 therebetween is made to be constant, thereby it is possible to finish the front and rear surfaces of the disc 3, uniformly and accurately in polishing.

Title: Digital video display circuit for manual map in radar system
Inventor: HIRAO RENTARO
IPC: G01S7/295
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To display a digital video of manual map in short time by generating a reference pulse (SCK) having shorter period than azimuth change pulse (ACP). SOLUTION: A pulse generating section 11 generates a SCK having period shorter than an ACP and delivers the SCK to a read address generating section 12. The generating section 12 comprises a P-ary azimuth address counter and generates an azimuth address ARAD based on a radar antenna azimuth ARG1 obtained by multiplying the free count of SCK by the azimuth corresponding to 1ACP. The distance address is generated conventionally. The read address RDA comprising the azimuth thus obtained and each distance address is inputted 7 and used as an address for reading the digital video VB of manual map from a digital video memory 2. Since the video VB can be represented by a time, i.e., the period of SCK multiplied by P, the entire circumference can be displayed in a shorter time than the entire circumference antenna display time using SCK having shorter period than ACP.

Abstract: PURPOSE: To deflect ion particles, so as to separate the scattered ion particles from neutral particles and to detect them by providing a means for synchronously applying an electric field to the particles scattered between a magnetic field prism for deflecting entrance particles and a sample. CONSTITUTION: Ion particles having low energy such as He, Ne, Ar emitted from an ion source 1 are pulsed through a chopping plate 2 and collides with a sample 8 after being deflected by a magnetic field prism 5. The collided ion particles are inelastically scattered to the sample front surface by atoms, and the ion particles to be scattered to the direction of 180 deg. are detected. The scattered ion particles partially becomes neutral particles by transferring of electric load to and from a front surface atom and reaches a detector 10. The ion particles not to be neutralized are deflected by a deflector 6 and reaches a detector 12. At this time, an ion particle convergence mechanism (lens) 11 is arranged in front of the detector 12, so as to converge the ion particles. Therefore, the scattered neutral particles and ion particles can be measured by being separated from each other.

Filed: 1985-12-26
Abstract: PURPOSE:To prevent unnecessary photographing by not performing release when the distance measured result after the expiration of a self-timer is changed from the first distance measured result just affer turning-on of a remote self- switch. CONSTITUTION:An automatic range finder is incorporated, and the distance is measured automatically at least twice by this device in case of selt-timer photography. If the absolute value of the difference between a distance measured result t1 (the first distance measured result) in a memory M1 and a distance measured result t3 (the distance measured result after the first self-timer operation) in a memory M3 exceeds beta, an output is not issued from a decision circuit 1e, and therefore, the release is not performed and the remote state is released. Thus, the accident that the release is performed to take an unnecessary picture when a photographer does not intend is prevented.

IPC: B23K3/02
Filed: 1987-11-24
Abstract: PURPOSE:To enable one hand soldering by taking the structure of a solder coming out to the tip of a soldering iron from a solder storing part provided at the part of a soldering iron tip and providing the valve cutting off the solder coming out of the storing part at the tip of a soldering iron. CONSTITUTION:When the tip of a soldering iron is strongly pressed to the part executing soldering, a valve 1 is pulled into the inner part and a gap is formed between the valve 1 and the tip part of the soldering iron. When a solder is inputted to a solder storing part 2, the solder of the solder storing part 2 at the inner side of the valve 1 is melted by the heat. Now when a gap is formed between the valve 1 and soldering iron tip part, the solder is flowed out of the gap to the external part. If the force pressing the soldering iron is reduced at the time when an optimum amt. of solder is flowed out to the external part, the valve is returned to the original position by the spring 6 force and no solder is flowed out to the external part. Soldering can thus be executed by one hand without the need to have a solder by one part of hands.
