Title: Roof tile
Inventor: SATO KUNIAKI
IPC: E04D1/28
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a roof tile on treading thereon, by sticking a reinforcing sheet parallel to the extending face of a plate body, thereon. SOLUTION: This roof tile 1 is made of a cement roof tile body 2 and a resin sheet 100 to form a plate body. The resin sheet 100 is integrally stuck on the part of the weakest mechanical strength at the rear face side 2R of the roof tile body 2. Polyethylene, a polyester, etc., can be used for the resin sheet 100. Since the reinforcing sheet 100 is stuck on the rear face side of the plate body in this way, the part exposed in the upper side when roof tiles have been laid, is constituted of cement roof tile bodies 2. Hence, fire-resistance against flame from the outside of house and favorable appearance can be kept and at the same time, toughness as the whole roof tiles is increased because of the reinforcing effect of the reinforcing sheet integrally stuck on the rear face.  Accordingly, the resistance against breakage at the time when treading on the roof tiles or transporting them is increased.

Title: Method for driving ink jet recorder
Inventor: SAKAI MARI
IPC: B41J2/14
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To make high speed ejection of an ink drop and stable execution of ink drop ejection operation by the number of high frequency waves compatible by a method wherein an ink drop is ejected from an ink nozzle by ink pressure generated by reduction of a volume of an ink chamber, and thereafter a diaphragm is again brought into contact with an opposed plate by execution of auxiliary charging. SOLUTION: An opposed electrode is formed between a bottom wall 51 and an opposed plate surface standing opposite thereto by putting an insulating film and a gap G between them. When drive voltage from a voltage impressing means is impressed between opposed electrodes, Coulomb force by electric charge charged between the opposed electrodes is generated, the bottom wall (diaphragm) 51 is flexed to a segment electrode 10 side, and a volume of an ink chamber 5 is expanded. When the electric charge between the opposed electrodes is rapidly discharged by the voltage impression means, the diaphragm 51 is returned by elastic return force, and the volume of the ink chamber 5 is rapidly contracted. A part of the ink filling the ink chamber 5 is ejected as an ink drop from an ink nozzle 11 interconnected to the ink chamber by ink pressure generated at that time.

Filed: 1991-07-16
Abstract: PURPOSE:To effectively make materials to be ground collide with the collision surface of a colliding member and to increase grinding efficiency by setting the central axis of an accelerating pipe in a vertical direction. CONSTITUTION:In a grinder, materials to be ground 14 is supplied from the feeding port 1 of the materials installed above an accelerating pipe 2 through an accelerating pipe throat part 3 to the accelerating pipe 2. When compressed air is introduced from between the inside wall of the throat part and the outside wall of the feeding port to the accelerating pipe 2, the materials 14 supplied to the accelerating pipe 2 is accelerated in a moment to obtain high speed. Then, the materials 14 jetted at high speed from an accelerating pipe outlet 4 to a grinding chamber 5 collide with the collision surface 7 of the colliding member 6 to be ground. At this time, the central axis of the accelerating pipe 2 is set in the vertical direction and the materials 14 are fed from the center of the throat part 3 of the accelerating pipe 2. Further, when the collision surface 7 is made to be in the shape of a cone having the apex angle of 110 to 175 deg., the ground materials are dispersed substantially in all the circumferential directions and the secondary collision with a grinding chamber wall 8 is generated to be ground further.

IPC: B05C5/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a developing device and a developing method capable of uniformly developing a photosensitive film on a substrate with a small amount of developer. SOLUTION: A scanning operation is started from a scanning starting position P1 by a developer discharge nozzle 11, and after the nozzle 11 reaches the end edge of a substrate 100, the substrate 100 is scanned by the nozzle 11 while the nozzle 11 is uniformly discharging the developer on the surface of the substrate 100, and thereafter, the nozzle 11 reaches outside the substrate through the other end edge. In the case of keeping the flow rate of the discharged developer constant in order to uniformly supply the developer onto the substrate 100, a scanning speed is set higher in an initial scanning section on the substrate, but, the scanning speed is set lower in the remaining section.  Besides, in the case of keeping scanning speed of the developer discharge nozzle 11 constant, the flow rate of the discharged developer is gradually increased in the initial scanning section, but, the flow rate of the discharged developer is made definite in the remaining section.

In case the second sheet sensing means 6 does not go out of paper sensing even though the specified period of time has passed since the same sensing means 6 sensed the leading edge of the sheet, i.e., no sensing of trailing edge is made, transport rollers 4, 5 are stopped a certain period after the means 6 sensed the leading edge of the sheet.

Title: Paper clip
Inventor: OKAMOTO YUTAKA
IPC: A47G33/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To remove displayed paper simply one by one by holding the displayed papers using a magnet sheet formed of a rubber sheetlike magnet, then hanging the papers at an elevated spot with the help of a suspension bar and pulling the papers downward when they are through with serving their purposes. SOLUTION: Magnet sheets 7 using a rubber sheetlike magnet attract each other on account of their magnetic force. Thus a displayed paper is inserted into each of the gaps between the magnet sheets 7, while the magnet sheets 7 attracted to each other are turned over one by one. Then after inserting a few number of displayed papers into the gaps, the paper clip is uplifted by putting a hook attached to the tip of a suspension bar into a hanging hole 3 and is hung onto a hanger fitted to the upper part of a wall surface. In this case, the displayed papers are retained without falling, due to the mutual attractive force of the magnet sheets 7. The displayed papers which are through with serving their purposes are pulled right downward starting with the paper nearest to a person who operates the paper clip.  This first paper can be removed easily and positively without breaking it and irrespective of the other papers.

Title: Measurement evaluation method for magnetic tape strength and thin magnetic tape
Inventor: NEGISHI HATSUO
IPC: G11B5/84
Filed: 1990-07-27
Abstract: PURPOSE:To evaluate the actual strength of a magnetic tape based on the added buckling load value by applying the load to the single end of the tape of an approximately square shape held in a loop form or an erected state and measuring the first buckling load in the lengthwise and breadthwise directions of the tape. CONSTITUTION:A magnetic tape piece 15 to be checked and cut into an approximately square shape of each side of 12.65 mm, for example, is put into a hole 14a of a holder 14 in a cylindrical shape where the lengthwise direction set in the vertical direction and the magnetic layer side set at the outside. At the same time, a pin 16 is inserted to the inside of the piece 15 and the piece 15 is pressed to the inner wall of the hole 14a. The holder 14 is put on a table 20 and an arm part 6 is moved downward at a prescribed speed. The first buckling load value measured in the lengthwise direction of the magnetic tape is added to the buckling load value measured in the breadthwise direction of the tape. Based on this added load value, the tape strength is evaluated. If the tape thickness is set at about 14.6mum with the first added buckling load value of both lengthwise and breadthwise directions set at about 18g, no damage is substantially given to the thin magnetic tape.
