Patent JP-H03254456-A (JP)
Title: Tape driver
Inventor: OTA HITOSHI
IPC: G11B15/32
Filed: 1990-03-02
Abstract: PURPOSE:To prevent occurrence of sound noise and uneven drive due to play caused by a gap between a reel key and a reel slot at tape running by bringing the reel key in press contact with the reel slot at all times. CONSTITUTION:When a cassette is loaded onto a supply reel disk 8 and a winding reel disk 9 of a tape deck, moving reel keys 11, 16 and an end of a reel slot 5 are in contact with each other and a reel slot 5 depresses the moving reel key 16. Since the moving reel key 16 is fixed to a reel hub 10 via a compression spring 17 in this case, when the moving reel key 16 is inserted into the reel slot 5, the compression spring 17 is compressed to depress the moving reel key 16 onto the reel slot 5 with a force in response to the compression of the compression spring 17. Thus, no gap is caused among the reel key, the supply reel and the winding reel onto the reel slot and occurrence of sound noise at tape drive and uneven drive of the tape and deterioration in the picture quality are prevented.

Title: Noise level estimating circuit
Inventor: TANIGUCHI TAKAYUKI
IPC: G01R29/26
Filed: 1995-03-13
Abstract: PURPOSE: To accurately estimate a noise level even if a desired signal level is high and the ratio of the existing time is large by providing a signal selector for selectively outputting a signal. CONSTITUTION: An input signal x[K] is level-smoothed by an absolute value calculator 101 and an LPF 102. A switch 103 outputs data from the LPF 102 once to a frame in a short time to a signal selector 104 as y[K1]. The selector 104 compares A input data with B input data, and outputs the smaller signal. A switch 109 is closed based on the count of a frame counter 108 for a long time and outputs an estimated noise level signal NL[K2]. A buffer memory 105 normally stores data of NL[K2], but, when the switch 109 is closed and the NL[K2] is output, it stores the logic maximum value which can be input to the terminal B of the selector 104. Accordingly, the NL[K2] is once updated to a long time frame.

Abstract: PURPOSE:To improve the light emitting efficiency of a fluorescent lamp by arranging a heating element near the fluorescent lamp, detecting the ambient temperature of the fluorescent lamp, controlling the temperature of the heating element based on the detected result, and making the ambient temperature of the fluorescent lamp constant. CONSTITUTION:A ceramic heater 12 functioning as the heating element constituting a heat insulating means is arranged in the corner part of a carriage frame 11 near the fluorescent lamp 10 in a 1st carriage 4.

Abstract: PURPOSE: To enable the detection of twodimensional displacement or position through a simple construction, by using a magnetoelectric transducing element and a magnetic scale provided with a twoidimensional magnetic lattice and by obtaining an output signal corresponding to the displacement.  
     CONSTITUTION: N-pole magnetized portions 5 and S-pole magnetized portions 6 are alternately provided in a magnetic scale 1 so that the magnetized portions 5, 6 are placed in longitudinal and latitudinal directions. A signaling magnetic field HSX of λ x  in wavelength is produced in the latitudinal direction between the magnetized portions 5, 6. A magnetic lattice is provided to apply the signaling magnetic field to a the magnetoelectric transducing element 2. The resistance of the electrical current passage 7 of the transducer 2 is changed depending on a bias current IB and the direction of magnetization. At that time, a detection signal whose level is repeatedly altered depending on the wavelength of λ x  appears in the current passage 7 due to the displacement of the converter 2. The signal is detected. A position in the latitudinal direction can thus be identified by the relative movement of the transducer 2. A position in the longitudinal direction can be also identified in the same manner.

Title: Recording method of information
Inventor: TERAO MOTOYASU
IPC: G11B9/10
Filed: 1996-03-11
Abstract: PURPOSE: To record information by a single laser beam by biasing the beam power to an erasing level and increasing the recording level of the beam for a specific time when overwriting the information using a single energy beam. CONSTITUTION: The power is raised to an amorphous level for a short time at the place where the recording medium is to be made amorphous in accordance with the information signal. When the information including a laser beam pulses of length more than twice a shortest pulse length is recorded, the laser beam is divided into original recording waveforms and plural short pulses and are radiated as shown in the center section of the waveforms in a figure. When the laser beam is divided into plural short pulses as mentioned above, it is desirable to make the power lower than a crystallization power level between pulses. By dividing the laser beam into plural pulses to be radiated, a recording pattern is formed on a disk to provide regerative signals which are faithful to original signals.

Abstract: PROBLEM TO BE SOLVED: To eliminate frictional resistance by pressurizing gas pressure supplied to a shaft seat part for several seconds during a rotor starting period when a pump is started, floating the rotor, and separating the stator and rotor from a part where a product is brought into contact with the stator and rotor. SOLUTION: A bypass piping 20 is arranged in front of the pressure reducing valve 14 of a shaft seal piping 21, and a solenoid valve 18 is opened by receiving an accelerating signal 17 when a pump is started from a control device 16. The solenoid valve 18 is opened only when the pump is started, and N2 supply pressure to a shaft seal part is equalized with the pressure of an N2 gas supply source 15. Then, the rotor 1 receives force in the direction of a suction port 6 and is floated in an upper direction by the part of the axial clearance of a bearing 7a. The solenoid valve 18 is opened by a timer 19 only for several seconds when the pump is started. The rotor 1 is floated at the time of starting, thereby the rotor 1 and stator 2 are separated from a product stuck thereto. Hereby, frictional resistance by the product is reduced, thus the pump can be normally started.
