Title: Laser doppler speedometer
Inventor: TASHIRO HIDEO
IPC: G01S17/58
Filed: 1987-02-04
Abstract: PURPOSE:To suppress a deviation in wavelength with temperature and to reduce errors in speed measurement by controlling a semiconductor laser to constant temperature. CONSTITUTION:A heat-sensitive element 12 detects the temperature of the semiconductor laser 2 and inputs it to an error amplifier 13. The amplifier 13 compares it with reference temperature T0 and the power amplification of the difference signal is performed to drive an electrothermal converter 15. The converter 15 is composed of a Peltier element; and one side of the element is joined with the laser 2 and heat is radiated from the other. When the temperature of the laser 2 is higher than a reference temperature T0, a positive current flows to the converter 15 to cool the laser, but when the temperature is lower, on the other hand, a negative current flows to heat the laser 2, which is controlled to the constant temperature T0 at all times. Thus, speed measurement errors due to a wavelength deviation are reduced.

Abstract: PURPOSE:To prevent a line from being occupied for a long time even in the case of transmitting the large capacity of file data in data communication. CONSTITUTION:A file transmission control part 1c of a transmission side node 1 receiving a file transmission response 13 requests the read of a file data 18 stored in a storage medium 1a to a file read control part 1b. At such a time, when the data 18 stored in the storage medium 1a can not be read by the request of one time of reading since the capacity is large, the reading is requested several times. According to this request of reading, the control part 1c reads the data 18 stored in the storage medium 1a while dividing them into plural blocks 18A, 18B... and afterwards, the first block 18A in this data 18 is transmitted from a communication control part 1e through a communication line 3 to a reception side node 2. Then, a file reception control part 2c of the reception side node 2 writes the first block 18A in the data 18, which is received through a communication control part 2d, through a file write control part 2b to a storage medium 2a and afterwards waits for a transmission end request 19 from the transmission side node 1.

Title: Coding device for television signal
Inventor: KIMURA JUNICHI
IPC: H04N19/51
Filed: 1987-02-06
Abstract: PURPOSE:To improve a compression efficiency by means of orthogonal conversion by adopting a function which reduces the electric power of a high-order term after it has been orthogonally converted for evaluation function for motion compensation. CONSTITUTION:The function showing the electric power of the high frequency component of a difference between blocks is used as the evaluation function of the similarity of the blocks. With using the evaluation function, the block in which the electric power of the high frequency component becomes minimum is searched, and a difference signal with the block is orthogonally converted. In such a time, the electric power of the high-order term which has been converted is reduced compared to the conventional motion compensation, and it concentrates around '0'. On the contrary, the electric power of a low-order term increases, and the dispersion becomes large. Since the dispersion of the low-order term is conventionally large, influence due to the increase in the electric power is less. As a result, the number of distributed bits to the high-order term decreases, and the number of distributed bits to the low-order term increases. Since the number of high-order terms is large, the number of whole bits for transmission reduces as the whole blocks, whereby the higher compression efficiency can be obtained.

Abstract: PURPOSE:To improve the water saving effect without deteriorating washing effect even if only several washing tanks among a multiplicity of washing tanks are used, by providing orifices in first and second discharge tubes for restricting a passage of each tube to a predetermined cross-sectional area. CONSTITUTION:An orifice 11 is arranged between a discharge tube 4 and a pipe 10, and a bore 11a is arranged at the center of the orifice 11 for restricting a passage into a predetermined cross-sectional area. The pipe 10 is provided with a collar 10a and a groove 10b and an O ring 13 is fitted thereon. An electrovalve 3 and respective bibcocks 5 are opened so that selected tanks 6 are supplied with water and wafers 8 are washed thereby. The orifice 11 is arranged in the passage of the discharge tube 4 so that the amount of water in each washing tank 6 is held at an appropriate level for that washing tank 6. When, for example, only one of among four washing tanks 6 is used, the amount of water supplied through the discharge tube 4 is regulated by the orifice 11. This amount of water makes little difference from that in the case of using all the four tanks, and the wafer can be washed by a predetermined flow of water. Since a pipe 1 can be rotated in a horizontal plane by 360 deg., extremely high workability can be provided.

Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To enable accurate count of the number of crossing tracks without being affected by a noise by counting the number of crossing tracks based on logical product of an edge signal and a Miller signal of a track cross signal.

A logical product circuit 8 performs logical product of a Miller signal 25 and the track cross signal 24, and generates an effective edge signal 27. Therefore, even when a noise is included in the Miller signal 25, as a noise does not appear in the effective edge signal 27, a count error is prevented and accurate track count can be performed. Furthermore, it is preferable that a direction discriminating circuit 9 and a count pulse separation circuit 10 are interlocked together in a waveform shaping circuit 4 and a counter in which a track counter 11 counts the number of crossing tracks based on both of a count down signal 29 and a count up signal 30 is set.

Abstract: PURPOSE:To keep off the deflection of substrate as well as to aim at improvement in operating reliability of an IC on-board machine, by installing such a device that drives a support plate up and down while keeping it in horizontality. CONSTITUTION:When an air cylinder is extended longer and a mobile base 5 is made to go up, a positioning pin being locked to this base also goes up together and is inserted into a positioning pin hole 2b of a substrate 2. Simultaneously with this, a support plate 9 goes up and comes into contact with a lower surface of the substrate 2 as in 9' shown in a virtual line. Therefore, even if force (integrated circuit inserting force) in a downward pressure direction is added to the substrate 2, there is no fear that this substrate is bent downward.
