Title: Contour detector
Inventor: YASUDA TETSUYA
IPC: G06T7/60
Filed: 1988-04-25
Abstract: PURPOSE:To reduce the capacity of an image memory by removing contour picture elements whose total number is smaller than a threshold value from a contour picture element sequence when the total number of the picture elements is smaller than the threshold value. CONSTITUTION:For example, when a command sequence regarding picture element data is inputted, contour elements shown by a dotted line are registered in a contour element table, their directions and coordinates are written, and the numbers of other contour elements which are connected before and after the contour elements Cj are written in a connection element number field. Then when the command sequence is inputted to a contour analysis part 2 and processed, the total number of contour picture elements in the picture element sequence is found and compared with the threshold value. Further, a short picture element sequence in the contour picture element sequence is removed as meaningless according to the comparison result. Consequently, the capacity of the image memory is reduced.

Title: Infrared ray heating furnace
Inventor: ICHIHASHI MASAHIKO
IPC: F27B17/00
Filed: 1989-04-22
Abstract: PURPOSE:To enable an infrared ray type heating furnace to be optionally varied between an open type and a closed type to obtain a high temperature and at the same time to facilitate a control over heating atmosphere by a method wherein a pair of reflector members having semi-ellipsoidal sphere surface are separably connected optionally through an intermediate ring provided with cooling air introducing holes and a quartz plate installing part. CONSTITUTION:An infrared ray lamp 3 is installed within one reflector la of a pair of reflector members 1a and 1b having a semi-ellipsoidal sphere reflecting surface 2. Reflecting surfaces 2 of each of the reflector members 1a and 1b are oppositely faced to each other and fixed at both sides of an intermediate ring 4 so as to constitute a heating furnace of closed type. One reflector member 1b is removed and a quarts plate 18 is fixed to the intermediate ring 4 in place of the reflector member lb, resulting in that an open-type heating furnace is attained. During its use as the heating furnace, an air cooled fan 20 is operated, resulting in that surrounding air passes from a cooling air introducing hole 3 of the intermediate ring 4 through a heating spacing 21 and the air is discharged from the air cooling fan 20. So, it is possible to prevent the reflecting surface 2 or electrodes or a quartz tube or the like from being damaged by hot heat. In addition, it is possible to fix an electrode 10b to a pipe 11 arranged in the intermediate ring 4 and use the infrared ray lamp 3 for a high electrical power of a single pole structure and thus a high power can be attained.

Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To improve dependence on visual angles and to provide the liquid crystal panel with a wide range of visual angles by providing the surface light source side of a liquid crystal panel with a dichromatic dyestuff-contg. sheet oriented in the major axis direction of dichromatic dyestuff malecules to the direction perpendicular to the liquid crystal panel. SOLUTION: Coloring occurs at the diagonal visual angle simply when the liquid crystal panel is provided with a phase difference film 108 and, therefore, the surface light source 101 side of a polarizing plate 103 is provided with the dichromatic dyestuff- contg. sheet 102a. The dichromatic dyestuff-contg. sheet 102a is so formed that the major axis of the bar-shaped dichromatic dyestuff molecules face a normal direction. The method of perpendicularly orienting the dichromatic dyestuffs is executed first by applying a perpendicularly orienting agent on a transparent substrate, for example, triacetyl cellulose film and baking the same. A liquid mixture composed of the dichromatic dyestuffs, nematic liquid crystals and UV curing resin is applied on the perpendicularly orienting agent and is cured by irradiation with UV rays.  The dichromatic dyestuffs dissolved in the nematic liquid crystal are oriented in their molecular major axis in the normal direction by the perpendicularly oriented film and are cured in this state.

Title: Crystal growth apparatus of cdte
Inventor: HOSOMATSU HARUO
IPC: C30B11/00
Filed: 1985-05-14
Abstract: PURPOSE:To titled apparatus, constructed to form a drill-like protrusion directing inward at the bottom of a vessel and increase the thermal conductivity from that of the formed crystals, and capable of preventing occurrence of many grain boundaries in the initial stage and producing effectively large-diameter crystals. CONSTITUTION:Crystals of Cd and Te at a chemical equivalent ratio are vacuum sealed in a cylindrical vessel 1, which is then contained in a heating furance 3, having a given length, and capable of setting a given temperature gradient to grow CdTe crystals in a crystal growth apparatus. In the apparatus, a drill-like protrusion 20 is formed from the central part of the bottom of the vessel 1 toward the interior of the vessel 1, and the protrusion 20 is formed from, e.g. graphite, to increase the thermal conductivity from that of the formed crystals. For example, when the vessel 1 is lowered from a region (a) at 1,150 deg.C to a region (b), the temperature is decreased from the tip part of the graphite 20 having a high thermal conductivity. Therefore, crystallization is started from the vicinity of the central part of the bottom 2 in the vessel 1 to form a convex state along the shape of the graphite 20. The crystallization moves in the tube wall direction even if there are grain boundaries 10 in crystals 9. The grain boundaried 10 growing on the tube wall do not enter the crystals 9, and the single crystals can be grown with certainty.

Title: Disk drive
Inventor: KAJINO OSAMU
IPC: G11B21/24
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To decrease the number of components of a tilt adjusting mechanism, to make the mechanism small-sized, and to improve the positioning precision of the guide shaft of a head as to the disk drive which adjusts the tile of the guide shaft by tilting it. SOLUTION: This disk drive is characterized by that shock resistance and the stabilization of the energizing force of a guide shaft are made compatible by forming an elastic member 16 which energizes the guide shaft and a stopper 15 in one body and making the spring constant of the elastic member small. Further, the stopper 15 is in an arch shape surrounding the guide shaft and the engagement part for a chassis is given a degree of freedom of rotation by hook shapes at both the ends, so the whole stopper deforms when a leaf spring deforms to make it possible to set the spring constant small as compared with the size of the leaf spring, thereby actualizing size reduction.  Further, part of the chassis serves as a member for fixing the guide shaft and stopper to decrease the number of components and reduce the size, and the guide shaft is energized by the elastic member against the fixation member for the guide shaft to improve the fitting precision of the guide shaft.

Title: Position detector
Inventor: TANAKA MASAKI
IPC: G01D5/249
Filed: 1987-04-24
Abstract: PURPOSE:To detect an absolute position immediately after a power source is turned on, by using a relative position detecting means and an absolute position detecting means, executing an origin correction by an absolute position data, and thereafter, specifying the present position by utilizing a relative position data. CONSTITUTION:When an object to be detected is rotated and migrated, a position information storage means and a detecting means move relatively, and the detecting means reads out serially position information on the storage means at every track. An absolute position detecting means decodes sector information on a sector information track, derives an absolute position against a reference position, and executes offset of a discriminating means. A relative position detecting means takes out a continuous pulse signal of a rate being proportional to a migrating speed of the object to be detected, from the position information, and thereafter, counts this continuous pulse and derives a relative position where the counting start time point is used as a reference. a discriminating means counts successively the relative position, based on the absolute position used as a reference, after the absolute position is specified, and the present position of the object to be detected is derived.

Title: Bucket type hydraulic turbine
Inventor: TAGAMI TADASHI
IPC: F03B1/02
Filed: 1979-08-11
Abstract: PURPOSE: To permit the hydraulic power to be efficiently utilized by allowing the projecting member fixed to each of the buckets radially arranged to collide with stoppers to turn each bucket in order to exhaust the water in the bucket at the lower end.  
     CONSTITUTION: A bucket 9 full of water approaches to pins 15 and 16 with the rotation of the water wheel. First, a horn 17 contacts with the front pin 16. This causes the bucket 9 to begin to rotate in the same direction as the rotation of the water wheel, and the water in the bucket 9 starts to flow out in the direction opposite to the direction of progress. When the bucket 9 further progresses, a horn 18 contacts with the rear pin 15, and the horn 17 and the front pin 16 are separated from each other. Consequently, most of the water in the bucket 9 is exhausted. Though the rotation of the water wheel causes the horn 18 to be disconnected from the rear pin 15, the bucket 9 continues to rotate and returns to the normal state. Exhausting the water in the direction opposite to the rotation direction of the water wheel contributes to the turning force of the water wheel, and compensates for the energy consumed by the automatic water-exhausting means.
