Abstract: PURPOSE:To remarkably reduce an accessing time, by using a fine actuator operated at high speed, moving a light spot, counting the number of tracks passing, and performing movement of comparatively short stroke at high speed. CONSTITUTION:A total seek time is the total sum of a time 1 required for the movement of rough seek, a setting time 2 until positioning accuracy enters within one pitch of a linear encoder 1, a time 3 until track follow-up is started, and a timer 4 required for the movement of fine seek, however, the movement of comparatively short stroke is performed by using cross track seek operated at high speed, and moving the light spot to a targeted track, counting the number of the tracks passing. In this case, an error due to the decentering of a disk can be corrected by the cross track seek by fine movement. In this way, it is possible to approach a position after completing the cross track seek to the targeted track considerably, and to minimize a correcting distance by a fine seek operation, and to shorten a fine seek time 4.

Title: Oxygen concentration detector for combustor
Inventor: WATANABE YOSHIYUKI
IPC: F23N5/12
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To determine lowering of oxygen concentration accurately and quickly regardless of pulsation of ion current by calculating the moving average value of ion current and making a decision that the oxygen concentration is deficient when the calculated value is lower than an incomplete combustion detecting level continuously by a specified number of times. SOLUTION: When combustion is started, a control section 12 determines a combustion quantity based on a room temperature and a temperature preset by a user and continues combustion. When combustion is continued, oxygen concentration in the room decreases gradually and the level detected at a section 11 for detecting ion current in combustion flame also decreases and combustion is stopped when the ion current level lowers below an incomplete combustion level. A moving average calculating section 13 samples ion current value every predetermined time and calculates a moving average value.  A comparing section 14 compares the incomplete combustion level sequentially with the moving average value and when the moving average value is lower than the incomplete combustion detecting level continuously by a specified number of times, a decision is made that the oxygen concentration has lowered and combustion is stopped.

Abstract: PURPOSE:To prevent deterioration in a high frequency component by utilizing the redundancy of an audio signal and utilizing a signal of a just preceding similar waveform thereby implementing the interpolation. CONSTITUTION:A digital signal for one period written at a time before one period in a timing of a zero cross point when a waveform of an inputted digital signal Din changes from a negative value to a positive value in memories 13, 14 is sequentially read from a zero cross point.

Title: Holding structure of heat exchanger
Inventor: MORISHITA TOSHIHIRO
IPC: F28F9/00
Filed: 1983-10-21
Abstract: PURPOSE:To absorb the gap of a heat exchanger body produced by the difference of thermal expansion coefficient, and to prevent fluid from leaking out to each other, by elastically holding the heat exchanger body in a casing, interposed by a spacer surrounding one side at least of an air feed opening of a heat exchanger body and by a rubber packing fitted to the end outside of the spacer. CONSTITUTION:A heat exchanger body is set in a casing 4 consisting of a metal case 5 and a heat insulating material 6. A depression 7 is formed inside the casing in order to set the heat exchanger body in it. A spacer 16 is inserted into the gap of an air feed opening 8 of a heat exchanger body so as to surround the opening 8, and the inside end of a spacer 16 is bonded to the heat exchanger body by an adhesive mortar 15. Highly heat-resistant rubber packing 17 is fitted to the end outside the spacer, and flange 13 fitted to the air feed opening 8 depresses the heat exchanger body to the inside by the intermediary of a rubber packing 17 and a spacer 16. Accordingly, the gap produced by the difference of thermal expansion coefficient can be absorbed by the elasticity of a rubber packing 17. Besides, fluid can be prevented from leaking, because the rubber packing 17 seals the outer periphery of the fluid fed opening of a heat exchanger body.
