Title: Method of etching indium phosphide crystal
Inventor: UDAGAWA TAKASHI
IPC: H01L21/308
Filed: 1984-10-05
Abstract: PURPOSE:To improve the reproductivity of etching speed by determining a capacity mixing ratio of hydrogen peroxide to phosphoric acid to be larger than the specified value when an InP crystal is etched by a mixed solution consisting of phosphoric acid, hydrogen peroxide, and water. CONSTITUTION:When an InP crystal is etched by use of a mixed solution of phosphoric acid, hydrogen peroxide, and water, a capacity mixing ratio of hydrogen peroxide to phosphoric acid is predetermined to be 0.10 or larger. Consequently, the reproductivity of etching speed can be improved easily without deteriorating a surface condition of the InP crystal and requiring any complicated operation. Accordingly, it becomes facile to form the structure which requires accurate control of an etching depth such as the recess structure, etc., e.g. those which are necessary for fabrication of an InP field effect transistor, or the like.

Title: Holding apparatus of filter for removing dust at high temperature
Inventor: TAGASHIRA KENJI
IPC: B01D46/24
Filed: 1994-09-01
Abstract: PURPOSE: To prevent a porous solid filter composed of ceramics, etc., from being damaged by vibration, and prevent stress generation in the filter due to heat. CONSTITUTION: Both edge parts of a filter 2 of a porous solid body are held by supporting ends 9, 10 to hold the filter by both edge parts and prevent the filter from being damaged by vibration. The supporting end 10 is composed of a material having different coefficient of linear thermal expansion from that of the porous solid body, and the length of the supporting end 10 is set up so as to make the heat expansion of a cylindrical part 10a of the supporting end 10 in the longitudinal direction at high temperature atmosphere at the time of use of the filter 2 equal to the heat expansion of the filter 2 in the longitudinal direction.  The expansion of the supporting end 10 is controlled by injecting a medium into a space between the filter 2 and the supporting end 10 so as not to cause relative displacement between the filter and the supporting end 10 at the time of temperature alteration such as rising up time, etc., and thus relative displacement between the edge part of the supporting end 10 and the edge part of the cylindrical part 10a is eliminated to prevent thermal stress generation in the filter 2.

Title: Preparation of heat storage board
Inventor: SARADA TOSHIO
IPC: C09K5/08
Filed: 1989-08-11
Abstract: PURPOSE:To prepare a heat storage board which is improved in mechanical strengths, heat storage and releasing properties, moldable into a plate, and does not cause buckling at its middle part during working by sticking a particulate material to latent heat storage particles into which a latent heat storage material is absorbed or soaked, putting these particles into a bag, and subjecting the bag to hot pressing. CONSTITUTION:A heat storage board is prepared by sticking a particulate material 3 (e.g. talc or Al2O3) to the surfaces of latent heat storage particles 2 into which a latent heat storage material is absorbed or soaked, putting these particles into a bag 1, sealing the bag, placing the bag in a mold 4, and subjecting the bag to hot pressing by using upper and lower heating plates 5. During the hot pressing, the temperature of the plates must be kept at not higher than the melting point of the latent heat storage particles, but not lower than the melting point of the latent heat storage material. Unlike conventional heat storage boards prepared by putting latent heat storage particles and a particulate material separately in a bag, which are inherently poor in mechanical strengths since the latent heat storage particles and the particulate material tend to move in the bag, the heat storage board prepared by this method is improved in mechanical strengths, heat storage and releasing performance, can be molded into a desired shape (i.e., plate), and hardly buckles at its middle part during working.

Filed: 1987-08-21
Abstract: Apparatus for spray coating plate-like or otherwise configurated workpieces has an endless apertured conveyor which transports a series of workpieces along a horizontal path beneath a rotary atomizer which sprays coating material onto the advancing workpieces. The coating material which bypasses the workpices and passes through the apertures of the conveyor impinges upon and gathers on a web of paper or non-woven fibrous material which is advanced at a speed less than the speed of the conveyor so that the web can be used with great economy because it is or can be advanced at a rate such that, or only when, its portion which is in the path of sprayed coating material cannot gather and retain additional coating material.

Title: Slider for magnetic head
Inventor: TAKAHASHI MINORU
IPC: G11B5/60
Filed: 1983-11-07
Abstract: PURPOSE:To stabilize the floating state of a slider by making the rail width of slide rails for the slider narrower at the lengthwise center part than that at both terminals of the rails. CONSTITUTION:Two slide rails 42 for the head slider 41 have narrower rail width at their lengthwise center parts than at an air inflow terminal part 42a and an air outflow terminal 42b. Therefore, when the head slider 41 floats by an air flow generated by the rotation of a magnetic recording medium 51, the air flow becomes easy to run out perpendicularly at the lengthwise center part of each rail 42, so the air pressure produced at the air inflow terminal part 42a of each rail 42 drops in the middle of the rail 42 and rises again at the air outflow terminal part 42b. Consequently, even if the head slider 41 has a gradient Q of about 5-10 deg. to the air flow direction, variation in pressure distribution due to an air film between the slide surface and a magnetic recording medium surface 51 is reduced and the head slider floats stably.
