Title: Manufacture of heat pipe
Inventor: SAKATANI MASUSHI
IPC: B29D23/00
Filed: 1987-12-09
Abstract: PURPOSE:To improve the thermal properties of a heat pipe by feeding a wound tape, forming a wick layer on one surface of the tape and then working the tape into a pipe shape. CONSTITUTION:A coiled metallic tape 1 of copper, aluminum, iron stainless steel, etc., is fed out of a feeder. Wick material 2 is made mainly of inorganic or organic fiber as a tape in the shape of net, woven or non-woven fabric and fed at the same speed as the metallic tape 1 under the state coiled on the feeder. The wick material is stuck on one surface of the metallic tape 1 to form a wick layer 21. At this time, adhesives 23 are injected from a nozzle 22 on the metallic tape 1. Then, the metallic tape 1 is formed in the shape of a pipe so that the wick layer 21 comes inside the tape and the seam 10 is welded. The deformation due to working which may happen thereafter has no effect on the adhesion of the wick layer 21.

Abstract: PURPOSE:To realize a measure for a hit rate improvement such as a disk block preceding reading, etc., at the up-date time of data without needing so much the bus band of a system bus by realizing a disk cache device with a dual port memory. CONSTITUTION:When the disk block is decided not to exist on a disk cache memory 42 in a deciding part 51, namely, at a miss hit time, a purging block in the disk cache memory 42 is determined. Then, while the data are written from a port 43 to the disk cache memory, the data are written from a port 44 to a disk device 7. Thus, in case of the up-date at the miss hit time of the disk cache memory, since the bus band of the system bus is not needed so much even when the preceding reading of the disk block is executed, the disk cache device of the high hit rate can be realized without lowering the performance of a system.

Abstract: PURPOSE:To obtain high resolution without high assembly accuracy, an increase in size, and a decrease in mechanical permissible speed of revolution by providing a hologram rotary disk where a code pattern is recorded, a light source, and a photodetector which detects an enlarged reproduced image. CONSTITUTION:When the hologram rotary disk 2 where the code pattern of a code plate is reduced and recorded is irradiated with the laser beam from a semiconductor laser 4, the enlarged and reproduced image Im where the code pattern of the code plate is enlarged is formed. Then an optical sensor array 7 placed at the image formation position of the reproduced image Im converts the pattern in a circumferential direction of the reproduced image Im into an electric signal, which is sent to an arithmetic circuit 10. The circuit 10 reads an address out of the signal of the digitized and reproduced image from the array 7, calculates an angle from the address, and displays an image on a display device. Consequently, the assembly accuracy of an element, etc., is relaxed and the rotary disk is miniaturized and the mechanical permissible speed of revolution is improved and the high resolution is obtained.

IPC: F02B77/08
Filed: 1989-11-30
Abstract: PURPOSE:To determine an input shaft torque accurately in a system using an engine by performing a learning operation using a motor based on revolutions of an input shaft or an output shaft obtained using the engine and an output shaft torque. CONSTITUTION:A sample 1 is driven using an engine and revolutions on the input side or on the output side thereof and an output shaft torque of the sample 1 are determined for each throttle opening or each parameter corresponding thereto with a data indicating hourly changes therein as reference data. The sample 1 is connected to a driver 3 equivalent to the engine in inertia in substance and an expected torque value of the device 3 at which a reference data is expected to be obtained is applied to the device 3 as torque specified value to operate and based on the data obtained from the operation and the reference data, the torque specified value is corrected to operate the device 3 again. This procedure is repeated until the data obtained approximates the reference data. The torque specified value at which approximation is gained or a detection value of an input shaft torque are estimated as input shaft torque value to be given when the reference data is obtained.

Title: Liquid jet recorder
Inventor: SEKIYA TAKURO

Filed: 1988-12-08
Abstract: PURPOSE:To get rid of cross talk by a method wherein a phase difference in driving of a thermal energy operation part is taken within a specific value when liquid drops are simultaneously discharged from adjacent orifices in a multiarray system of a bubble type ink jet. CONSTITUTION:In the case where recording paper 5 moves, and orifices are considered to be arranged sideways and are simultaneously driven, since pixels 1 and 2' come into line sideways as given in the figure in the case of no stroke between the orifices, when a phase of driving of the orifice is shifted in order to solve this problem, the paper is moved though the stroke is gone. When a relative speed of the head to the paper is taken as Vhp(m/s) and a maximum diameter or a maximum size at the maximum bubble to be formed is taken as D(m), image quality is kept high by recording discharge drive when discharge is performed almost simultaneously from the adjacent orifices within the formula [I].

Abstract: PURPOSE:To simplify construction by mounting a pickup guide body with the tilting thereof adjustable freely. CONSTITUTION:A tilt contact part 67 for top surface is made to abut upper and lower pickup guide bodies 22 from the underside while a pickup base 21 is moved onto the guide body and turn carriage motor is rotated forward and backward to control the lifting of a turn carriage 40, so that the guide body is rocked with the contact part 56 centered on a support rotary shaft in a range of 1 upward and 2 downward to perform a tilt adjustment of a pickup 19 with respect to the warping of a disc 7. In this manner, with the lifting operation of the carriage 40, the tilt adjustment is accomplished to differentiate tilt adjusting values of the guide bodies 22 and 23 between those upward (1 degree) and downward (2 degree) thereby holding the overall height of a set down low. As a result, when contact parts 67 and 68 for upper and lower surfaces are arranged separately -- even with inclination thereof different, a spherical guide 45 of the carriage 40 is positioned in extension of pickup rails 29 and 30 to allow smooth movement of the base 21 to the carriage 40 thereby simplifying the construction.
