Title: Apparatus for manufacturing axial fan
Inventor: BABA MASAICHI
IPC: F04D17/04
Filed: 1978-06-07
Abstract: PURPOSE: To permit discs carrying blades inserted therein to be separated and positioned while being held aginast inclination by providing a chuck for holding the discs.  
     CONSTITUTION: Discs 4a to 4d are stacked on a chuck 1 and positioned with positioning pins 2, and then a number of blades 5 are inserted through grooves formed in the discs 4a to 4e and secured thereto. Subsequently, a stepped shaft 3 is raised, whereby pulling shafts 6 are raised. As a result, the disc 4a is separated by the first shoulder of the stepped shaft 3, and at the same time support arms 10a of a lift block 7a being raised by the pull-up shafts 6 are forced out toward the axis of the stepped shaft 3 by cams 9, thus bringing a plate spring mounted on the underside of the support arms 10a into contact with the upper surface of the disc 4a. Thus, even if fluctuations of the frictional force between the grooves of the disc 4a and the blades 5 are produced, the disc 4a can be separated without being inclined since the support arms 10a are in contact with the upper surface of the disc 4a.

Title: Preparation of alumina with low content of radioactive element
Inventor: SHIODA SHIGEAKI
IPC: C01F7/02
Filed: 1980-05-23
Abstract: PURPOSE: To obtain alumina suitable for using in a semiconductor memory apparatus, by pulverizing a calcined alumina consisting of substantially an α-crystal, and washing the pulverized crystal with a dilute mineral acid solution.  
     CONSTITUTION: Calcined α-alumina must be finely pulverized in order to elute uranium and thorium in a solution of a mineral acid, e.g. nitric acid, by the treatment with the mineral acid solution. After the treatment, the alumina is separated from the mineral acid solution by the solid-liquid separation. The nitric acid is most effective as the mineral acid, and followed by sulfuric acid. Hydrochloric acid has a little effect. The concentration of the mineral acid is preferably about 0.5W0.1N. The resultant separated alumina is then washed fully with water and dried.

Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the wastage of transmission/reception processings and to perform command retransmission at optimum time by performing the command retransmission considering the convenience of a reception station. SOLUTION: When a reception station A is incapable of reception for commands/data from a transmission station 10, the reception station A calculates time until the reception becomes possible and imparts it as interval time, until retransmission in a response to the transmission station 10. The transmission station 10 which receives the response registers the interval time in a management table, checks the table at every fixed time interval and retransmits the commands/data to the reception station which reaches the interval time, and thus the efficient transmission/reception of the commands/data can be performed.

Title: Manufacture of semiconductor device
Inventor: TSUCHIYA KENJI
IPC: H01L21/304
Filed: 1988-03-24
Abstract: PURPOSE:To reduce warpage of a semiconductor substrate due to film stress by providing grooves at any process time of forming and at any position on a film to be deposited on the principal plane of the semiconductor. CONSTITUTION:When a semiconductor substrate has been warped, grooves 1 and formed on a deposited film in a dicing line portion on a water by a laser beam. The number of grooves may be increased as necessary, although two grooves, one vertical and one horizontal, are formed in this case. The depth of the groove may take any value, shallower or deeper than, or equal to the deposited film thickness insofar as the warpage of the semiconductor substrate can be reduced to within + or -1-2mum accuracy of which is required for highly accurate patterning. The width of the film may be substantially zero microns if the surface of the substrate is warped in recess and it may be several microns if the surface is warped in projection. No high accuracy in terms of position is required as far as the grooves are positioned within the dicing line portion. The grooves may also be formed on chips on the condition that some chips are sacrificed. Substantially no positional accuracy is required in this case. The grooves may be formed at an arbitrary forming process before the lithography process as far as the warpage of the semiconductor substrate can be reduced.

Title: Magnetic erasing method
Inventor: SASAKI AKIHIKO
IPC: G11B5/024
Filed: 1988-03-24
Abstract: PURPOSE:To eliminate an adverse effect due to switching noise by erasing record information by permitting a prescribed erasure current to flow on a magnetic head as decreasing the rotating speed of a recording medium gradually. CONSTITUTION:At the time of erasing a video signal recorded on a magnetic disk, an erasing switch 20 is operated after setting a change-over switch 9 at an erasure mode. By the above operation, a system controller 19 drives an erasure current generation circuit 14, and generates an erasure current whose polarity changes at every constant period and whose amplitude decreases gradually. And the erasure current is impressed on the coil 10 of the magnetic head 2, and also, the rotating speed of a motor 15 is decreased gradually via an amplifier 18 for driving the motor. Thereby, since the switching position of the polarity of the erasure current is moved at every rotation of the recording medium, superposition on one point can be evaded, and the adverse effect of the switching noise can be eliminated.

Title: Picture reader
IPC: H04N1/04
Filed: 1992-03-26
Abstract: PURPOSE:To reduce optical noise due to an undesired light reflected in an end face of a mirror, to improve the contrast, to sharpen thin lines and to extend gradation performance without incurring a remarkable cost increase by applying a means to prevent incidence of a reflected light from the end face of the mirror to a lens to the end face of the mirror. CONSTITUTION:Satin-finish is applied to an end face 1a of mirrors 1, 2 toward an original and a light source. Thus, even when a reflected light from the original or a light from the light source is made incident in the end face 1a, the light is reflected irregularly to prevent from being made incident in a lens. As the reflection prevention processing method of the mirror end face 1a, a method of paint in a black group color or a method of adhesion of a black tape or a textured tape may be adopted in addition to above. At least an end ridge of a reflecting face in crossing with an end face of the 2nd mirror 2 extended lengthwise is fitted to a bracket 8 whose surface is painted in black and supported, then a ray is absorbed, a deflection is prevented and the sharpness of thin lines is especially improved.
