Title: Wall material and manufacture thereof and wall material molding mold
Inventor: ONISHI YUJI
IPC: B29C33/42
Filed: 1994-12-08
Abstract: PURPOSE: To efficiently obtain a sample and a practical commodity of a wall material having a favorable and the same surface pattern by a method wherein a coating material is cast-molded in a wall material mold having recessed parts, on the bottom surface of each of which the rugged shape corresponding to the desired surface pattern is formed. CONSTITUTION: A coating material diluted with a small amount of an aqueous solvent is cast in the recessed parts 4 of a silicone rubber wall material mold 1. When the coating material hardens after the elapse of a predetermined period of time after its casting, the wall material mold 1 is turned over by being folded at its end part side, resulting in taking out a wall material, the coating material of which is hardened. By pasting the taken-out wall material with an adhesive, for example, on a mounting paper, a sample is obtained. Thus, wall materials having the same surface pattern are obtained at all times. Further, the sample and practical commodity of the wall material having a favorable and the same surface pattern can efficiently be obtained.

Title: Pressure reducing valve system
Inventor: NANAO TERUAKI
IPC: G01F1/38
Filed: 1988-11-30
Abstract: PURPOSE:To reduce the cost and constructing time of the title system by calculating a flow rate based on the differential pressure before and after a pressure- reducing valve and the opening of the valve so as to omit a flow meter. CONSTITUTION:An orifice pressure-reducing valve 2 is installed to a fluid conduct line 1 and pressure fetching ports 4A and 4B are provided before and after the valve 2. A differential pressure measuring means 10 outputs a differential pressure signal based on a fetched pressure. The valve 2 is provided with a valve member, the displacement of which is detected by means of an opening sensor in a housing cylinder 7A as the opening of the valve 2, and the opening signal is sent to an arithmetic means 11 through a lead wire 7a. The means 11 calculates the flow rate of the line 1 from the differential pressure signal and opening signal and forms a flow rate measuring device 9. Therefore, no flow meter is required for the line 1 and the line can be reduced in length. Moreover, since the valve chamber can be reduced in size, the cost and constructing time of this pressure-reducing valve system can be reduced.

Title: Image scanner and start-stop control method
Inventor: SUNAZAKI TOMOHIRO
IPC: G06T1/00
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To ensure the smooth joining of images to improve the image quality at present, where the higher resolution and deeper reading density are required and also the start-stop frequency increases due to the increase in the quantity of data to be read, in contrast to the conventional image scanner where the image read start timing is not completely synchronized with the exciting timing of a motor that moves the reading position to cause a timing error equivalent to a single line of reading resolution in a start mode after a stop mode, and accordingly the data are read with redundancy/omission that is smaller than the quantity equivalent to a single line of resolution, which defective reading result, however, could be disregarded for the resolution and reading density of the conventional image scanner device. SOLUTION: A means is prepared to secure the same time difference between the image reading start timing and the exciting timing of a stepping motor that moves the reading position before the image reading is discontinued and when the image reading is restarted. Thus, the start-stop image error can be eliminated.
