Title: Wafer polishing device
Inventor: INABA TAKAO
IPC: B24B37/12
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a wafer polishing device giving high polishing accuracy and fine finished-surface roughness. SOLUTION: Polishing liquid 20a is supplied into a cavity part (a supply flow passage), which is formed inside a surface table 18, and oozes through the surface of an abrasive cloth 16 after passing through a porous pad. As a result, even when a wafer 12 and the abrasive cloth 16 are adhered tightly to each other, the polishing liquid 20a is uniformly and sufficient supplied onto the surface to be polished. In addition, the polishing liquid 20a supplied is moved toward the outer periphery due to centrifugal force caused by the rotation of the abrasive cloth 16. Since the polishing liquid 20a moved toward the outer periphery is sucked by a gap, which is formed along the outside of the surface table 18, the polishing liquid 20a containing chips will not remain on the upper surface of the wafer 12, and fresh polishing liquid is constantly supplied to the surface to be polished.  With this contrivance, flaws, which are produced on the surface of the wafer 12, can be prevented, and both polishing accuracy and finished-surface roughness can be enhanced.

Title: Pitch detecting device
Inventor: DAISHIYOUJI TAKESHI
IPC: G10L25/90
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To accurately find a pitch cycle fast with inexpensive constitution even when a speech waveform is a complicated waveform containing an overtone component, and prevent an improper pitch cycle from being outputted even when the improper pitch cycle is calculated owing to abrupt variation of the speech waveform, etc. SOLUTION: A binarization part 8 and a timer 9 find and store successive zero-crossing intervals of a digital speech signal supplied from the precedent stage. A pitch arithmetic part 11 assumes that a pitch cycle is the sum of 2n pieces of zero-crossing intervals data as to n=1-4, and calculates a reproduction rate as the degree of matching in each pitch cycle of each zero-crossing interval data constituting one pitch cycle. Then the highest reproduction rate is within a permissible range, the assumption by which the highest reproduction rate is obtained is employed to find the pitch cycle.

Title: Controller of air conditioner
Inventor: SUGIMOTO TATSUHIKO
IPC: F24F11/02
Filed: 1986-01-14
Abstract: PURPOSE:To improve the indoor vertical temperature distribution and to prevent a body-felt cold air flow from blowing off in the vertical direction during the space cooling operation by determining the direction in which air heat exchanged by a difference between an indoor air temperature and the temperature of an indoor heat exchanger. CONSTITUTION:An indoor air temperature detected by a temperature sensor 7 is set in a resistor T1, and a heat exchanger temperature detected by a temperature sensor 8 is set in a resistor T2. If an operational mode is space heating, a calculation of T2-T1, is carried out, and when the calculated value is larger than a predetermined value N, an air flow direction changeover plate 4 is driven so that air is blown off through a vertical blow-off port 6'. When the calculated value is smaller than the predetermined value N, the air flow direction changeover plate 4 is driven so that air is blown off through a horizontal blow-off port 6. In a case where air is blown off in the horizontal direction, when the result of the calculation of T2-T1 is larger than the predetermined value N, the blow-off direction is made vertical, whereas in a case where the vertical blow-off port is used, and the calculated result is less than a predetermined value N1 which is less than the value N, it is changed into the horizontal blow-off port.

Title: Track jump detecting device
Inventor: MORIYA MITSURO
IPC: G11B7/085
Filed: 1986-01-14
Abstract: PURPOSE:To improve the reliability of a track jump detecting device by stopping transmission of the reproduced signals when the signal of a track jump detecting means is produced during the reproduction. CONSTITUTION:A modulation circuit 26 sends signals to a track jump detecting circuit 22 via a line 23 for a recording period. The circuit 22 detects the start and the end of a recording action by the signal received from the circuit 26 and then ignores the output signals of a wind comparator 20 immediately after the start and the end of the recording action. This ignoring time is short and the occurrence of a track jump is prevented even though a track jump detecting device received an impact from outside. In such a way, the signals sent to an external device are stopped after a track jump is detected in a reproduction mode and then the desired signal is transmitted after the second detection of the track jump. Thus the reliability of the track jump detecting device is improved.

Title: Method for controlling air flow of sintering machine
Inventor: SAKURAI AKIO
IPC: C22B1/20
Filed: 1984-01-17
Abstract: PURPOSE:To improve the quality and yield of sintered ore and to reduce electric power for releasing air, etc. by decreasing suction negative pressure via an air box upon the sintering raw material charged and laminated on a pallet and moving thereon smaller in the initial and end periods of a calcination reaction than in the intermediate period. CONSTITUTION:Air permeating resistance is low in the initial period 1X for calcination of the above-described sintering raw material moving on a pallet 1 and therefore the suction negative pressure is determined low and the flow rate of the suction air to be passed through the sintering layer is decreased to realize the gentle calcination to obtain a heat holding effect. A wet zone is generated in the sintering raw material layer and the air permeating resistance increases in the so-called middle period 1Y of calcination from the end point of the period 1X up to just before or near the completion point of calcination and therefore the flow rate of the suction air is increased to improve productivity. The suction negative pressure is decreased in conformity with the decrease in the air permeaing resistance to decrease the flow rate of the suction air in the end period 1Z just before the completion of calcination which is the end point of the period Y or up to an ore discharge part 1B beyond the point near the same. As a result, the sensible heat of the sintered ore is effectively recovered.
