Patent JP-S5640084-A (JP)
Title: Heat exchanger
Inventor: HIDAKI MORIHISA
IPC: F28D7/10
Filed: 1979-09-10
Abstract: PURPOSE: To reduce deposits and to avoid influence of thermal stress, by providing a partition parting a casing into two chambers, suspending double tubes, introducing a high temperature gas from the upper chamber into the double tubes, and letting cooling water flow countercurrently.  
     CONSTITUTION: The high temperature gas enters at an inlet 6, flows down through an inner tube 13 of each double tube, is released at a lower end of the double tube 2 into the lower chamber, ascends along an outer tube 14, and then is discharged from an outlet 7. Water is supplied through a supply tube 8, branch tubes 9 and spaces 16 of the double tubes 2 and is delivered through branch tubes 10 into a boiler drum 12. During this period, heat exchange occurs and the gas is cooled while the water is heated. By this constitution, the high temperature gas containing dust is cooled rapidly to a temperature at which side reactions are slowed enough, then the gas is turned to ascend while dust is separated and therefore deposits can be reduced. As the double tubes are suspended from the partition, the thermal stress will be obviated. Thus a double tube type heat exchanger suitable for a waste heat boiler is obtained.

Title: Wafer attraction fixed base
Inventor: SERIZAWA MASAYOSHI
IPC: H01L21/683
Filed: 1982-07-05
Abstract: PURPOSE:To remarkably reduce the probability that warp generates on a wafer, even when foreign matters are deposited on the back surface of a wafer or the top surface of an attraction base, with the difficulty of receiving the influence by the foreign matters. CONSTITUTION:The top surface of an attraction base 5 is finished to an accurate flat, and thus a reference flat 6 is formed, then said attraction base 5 is magnetized. The attraction base 5 is formed into a circle of slightly smaller diameter than the diameter of the wafer 3, and a projection of the height H is formed by fitting a rise rim 7 in the outer periphery thereof. Many steel balls 8 of the diameter H are formed and arranged on the reference flat 6 which is the top surface of the attraction base 5, and then spread all over inside the rise rim 7. When the wafer 3 is mounted on the attraction base 5, and a connection hole 10 is connected to a vacuum source P, the wafer 3 is attracted in vacuum toward the steel balls 8 and the rise rim 7. Thereat, even when the foreign matter 11 is deposited on the back surface (lower surface) of the wafer 3, the probability that the foreign matter 11 contained in the clearance surrounded by the steel balls each other and the wafer and deposited on the back surface of the wafer 3 has influences on the wafer 3 and thus generates warp is remarkably low.

There fore, the voltages at both ends of the constant current sources 8 and 5 become equal, and elements Q51-Q516, and Q8 constituting the constant current sources 8 and 5 are operated simultaneously. As a result, the prescribed ratio in the output current can be satisfied.

Abstract: PURPOSE:To attach a converter to a reflector at a prescribed position by turning a drawing screw rod in order to put both end parts of a belt close to each other and reducing the diameter of the belt. CONSTITUTION:The end parts 23 and 23 of a nut 26 and a belt 22 are put into the recess parts 14 and 14 respectively. A converter 8 is put between the end parts 23 and 23 of the advance U-shaped belt 22 after increasing the space between both parts 23. Then a parallel part 31 is set along an attachment surface 12 and at the same time a flange part 33a abuts a base 11. Then a driver is put into an operation hole 18 and a screw rod 25 is turned in the damping direction. Thus the end parts 23 of the belt 22 are drawn to each other via a screw head 25a of the rod 25 and the nut 26. As a result, the diameter of the belt 22 is reduced. Under such conditions, the rod 25 is put through a through hole 24 at the parts 23 and therefore these parts 23 never float over the base 11. Therefore an upper semicircular part 22a of the belt 22 positioned on the converter 8 is drawn toward the base 11.

Title: Magnetic recording and reproducing device
Inventor: ITOU SATOSHI
IPC: G11B5/53
Filed: 1978-09-22
Abstract: PURPOSE:To obtain a magnetic recording and reproducing device with a little generation of beat noise due to a drop-out or cross talk between adjoining tracks, by giving a video head a difference in level between CH1 and CH2. CONSTITUTION:As for recording reproduction only at a normal speed, head fitting step (alpha) is zero and in variable-speed reproduction, fixed step (alpha) is provided so as to suppress a drop-out and cross talk between adjoining tracks. As a result, recording track width becomes unbalanced between CH1 and CH2, but cross talks 5a and 5b of adjacent tracks of respective heads become balanced. At this time, outputs of respective heads are equal in minimum value and the cross talks of adjacent tracks are driven away vertical on a regenerated picture, so that picture quality can be secured. In this way, the generation of beat noise due to the drop-out and cross talk between adjacent tracks can be reduced.

IPC: H01L29/772
Filed: 1991-05-21
Abstract: PURPOSE:To realize the pseudo signal delay of 0.5 bits by dividing signal charges into halves so that one is transferred by odd bits via a branching route and the other is transferred by odd bits plus 1 bit via the other branching route, and finally collecting the signal charges transferred from the two routes. CONSTITUTION:The signal charges Q1, Q2 and Q3 transferred in sequence in an input side transfer route CCD1 are divided into halves respectively in a branching section, and respective halves Q3/2. Q2/2 and Q1/2 are separated to the upper and lower branching routes to be transferred. Then two consecutive signal charges having a difference of 1 bit are respectively added by halves of them in the collecting section. As the result, a half of Q3 is added to a half of Q2 to make Q2.5, and a half of Q1 is added to a half of Q2 to make Q1.5, for example. Thus the pseudo signal delay of 0.5 bits can be obtained.

IPC: B41J2/345
Filed: 1983-06-29
Abstract: PURPOSE:To raise the life characteristics of heating resistors without damaging the function of a thermal recording head due to deterioration of the heating resistor region by providing separate electrodes in a staggering manner on the outside of the heating resistor regions provided in a belt form on both sides of a common electrode. CONSTITUTION:A pattern of separate electrodes 1 and 1' and a common electrode 2 are formed on a heating resistor layer 3' on a ceramic base plate 6 to obtain a thin-type thermal recording head. Since the step difference between the heating resistor region 3, the separate electrodes 1 and 1', and the common electrode 2 becomes smaller, when a heat-sensitive paper is placed across the heating resistor regions 3 in two rows, provided on both sides of the common electrode 2, the contact between the paper and the heating resistor regions 3 is improved. Also, since electric current flows keeping away from the deteriorated portion 4, no problems arise practically and damage to the function of the thermal recording head can be avoided.

Title: Chopper and preform analyzer using it
Inventor: SAKANO TATSUYA
IPC: G01M11/02
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To improve measurement precision of a preform analyzer which uses a space filter method using such chopper as dispersion in angular moment is less with a single window. SOLUTION: On a transparent substrate 26 of molten quartz, etc., an opaque thin-film 28 comprising a window 30 part is laminated by such technique as photo-etching to obtain a chopper 20. The transparent substrate 26 allows 100% of light ray to transmit in the range of thickness 0.1-a few mm, while the opaque thin-film 28 almost entirely shields the light ray with a few μm. Thus, the angular moment of the chopper 20 almost depends on the transparent substrate 26, so the dispersion in angular moment is so small as to be ignored. Thus, such preform analyzer as using the chopper is significantly improved in its measurement precision.

Abstract: PROBLEM TO BE SOLVED: To provide the information processor which can easily be powered off without being broken or using any special hardware signal when the power switch is turned on in whatever state the processor is used. SOLUTION: On detecting the power switch 3 being off, a keyboard controller 1 outputs as a DATA signal a key code for emulating keyboard operation for predetermined shutdown and it is supplied to a main CPU through an I/O (input/output) chip 6 and an internal bus 7.
