Title: Production of roll-shaped metallic die for information recording medium
Inventor: KUWABARA TETSUO
IPC: G11B7/26
Filed: 1987-04-30
Abstract: PURPOSE:To obtain a satisfactory roll-shaped metallic die by applying a dry or wet etching process together with rotations of a roll-shaped metallic die base material. CONSTITUTION:A circumferential wall 5 of a roll-shaped metallic die base material 2 is finished into a mirror surface by polishing or grinding. Then a photoresist is coated on the wall 5 and the laser beam exposure and development processes are applied for production of a mask of a prescribed resist film. Then the material 2 undergoes a dry etching process in a vacuum tank 3. In other words, the material 2 containing a resist film mask is attached to a base material holder having a rotatable mechanism. Then an Ar ion beam, a CF4 ion beam or a mixture ion beam of Ar and CF4 is radiated from an ion gun 1 under a vacuum state. Thus the material 2 is etched into the prescribed depth with rotations for production of grooves. Thus it is possible to produce the track grooves of an optical information recording medium in a continuous integrated process of a roll-to-roll system.

Title: Fixation device with heat roll
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/20
Filed: 1982-06-19
Abstract: PURPOSE:To prevent the generation of folding and creasing, by releasing beforehand a nip part before at least the forward end of a support body arrives at the nip part, and bringing a fixing roll into press contact with said body after the support body passes the position corresponding to the front end part on the advance side of the support body. CONSTITUTION:When the angle theta made by the tangents l, l' of a heat roll 1 and a pressurizing roll 2 at the front end part P of a nip part 11 decreases in the state just prior to nipping of the froward end of a support body into a fixing device with the heat roll, the component of force (x) of press contact forces alpha, alpha' decreases, and the component of force (y) of frictional conveyance forces beta, beta' increases and the value (y-x) increases, thus increasing the effect of nipping the support body 12. Therefore, the nip part is eliminated or is made extremely small before the forward end of the support body arrives at the nip part. The fixing roll is brought into press contact therewith after said body passes the position corresponding to the front end part of the nip part. Thereupon, a control signal circuit 28 detects the point of the time when the forward end of the support body 23 arrives, judges the timing when the paper is nipped surely in the nip part and generates a control signal. A nip control circuit 29 upon receiving said signals drives an electromagnetic clutch, solenoid etc. for controlling the nip part.

Inventor: SUZUKI MOTOYUKI
IPC: G11B20/18
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To shorten a wait time by a certify process and record dynamic image information in real time by recording information after carrying out a defect detect operation via predetermined track intervals. SOLUTION: A light beam is moved to a certify start sector. Data for detecting defects is inputted from a data-generating circuit 40 to an encoding circuit 29 via a selector 41, and recorded by a predetermined number of blocks. Then, the light beam is moved again to the certify start sector to start reproducing data. A CPU 21 obtains from a decoding circuit 39 information such as the number of errors when the data of the number of blocks recorded before is reproduced, or the like. When the number of errors is not smaller than a predetermined number, a defect is judged and information on the position is stored. When a volume of dynamic image information transmitted to a buffer memory 28 reaches a predetermined volume, the certify start sector at the time point is stored as a certify end sector to a memory and the operation is terminated.

Abstract: PURPOSE:To form a VCO where an electric characteristic of a circuit element other than a tank circuit is immune to the effect of the oscillating frequency by synthesizing a phase lag and lead signal respectively via a gain variable amplifier and feeding back the result to the tank circuit. CONSTITUTION:A series circuit consisting of a phase shifter 5 comprising a resistor R1 and a capacitor C1 and a phase shifter 6 comprising a resistor R2 and a capacitor C2 is connected to a terminal E to which a tank circuit is connected. Then a phase lag signal across the resistor R2 and a phase lead signal across the capacitor C2 are given respectively to gain variable amplifiers 1, 2.

Signal arrival times tauBi and peaks bi are extracted from wave form data and three detector signals are detected from smalle values of tauBi as TBi-TB3 and three detector numbers from large values of bi are detected as CB1-CB3. In the next step, the time order data TAK1, TAK2, TAK3 of each known sound source in a memory apparatus and peak order data CAK1, CAK2, CAK3 therein are successively read to be compared with time and peak data of an unknown sound source to select a known sound number kaving similarity.
