IPC: G03G15/00
Filed: 1993-12-27
Abstract: PURPOSE:To simply clean or replace an original pressing means such as a white pressure board or a white platen roller without especially opening an entire original carrying path by adopting the configuration such that the original pressing means pressing an original for an image sensor is opened externally from an opening. CONSTITUTION:A white pressure board 9 as an original pressing means is used and an opening 10 opening the white pressure board 9 to the outside of an upper case 2 is provided above the white pressure board 9. Through the constitution above, the white pressure board 9 is extracted from the opening 10 to an outside independently pressure release of a 1st roller 6 and a 2nd roller 7 without opening an entire original carrying path and then cleaning and replacement of the white pressure board 9 is facilitated. Thus, even in the case of the reader whose upper case 2 cannot be opened, a picture with excellent gradation is always obtained by cleaning and replacing the white pressure board 9. Furthermore, even in the case of the reader opening the upper case 2, the cleaning and replacement of the white pressure board 9 is facilitated.

Title: Production of polyester
Inventor: KURATSUJI TAKATOSHI
IPC: C08G63/85
Filed: 1991-12-12
Abstract: PURPOSE:To produce a polyester which can give a molding of excellent transparency by bringing a polycondensate, obtained by using crystalline GeO2 in a state of aqueous colloid as a catalyst, into contact with saturated steam. CONSTITUTION:A process for producing a polyester comprising an acid component based on an aromatic dicarboxylic acid and a glycol component based on ethylene glycol, wherein polycondensation is effected by using a catalyst comprising crystalline GeO2 in a state of aqueous colloid and the obtained polycondensate is brought into contact with saturated steam (desirably at 130 deg.C or above for 2 hr or shorter). The resulting copolyester has low internal haze, is reduced in the deposition of oligomers on a drum or a mold even when melt- molded for a long time, and can give a highly transparent molding because of low diffused reflection on its surface.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To contrive to enhance workability and reduce a material cost by mounting a triangle-shaped strip for finishing work at a chamfering area of a concrete post or a concrete beam or the like with an aluminum or the like- made fixture which is L-shaped in a cross section without using a blanking board. SOLUTION: When concrete is cured and a form is removed and then the surface of a chamfering area is to be arranged, the chamfering area is coated with mortar and then a triangle-shaped strip whose cross section is L-shaped, is pasted on the area. The strip is pressed, thereby smoothing the chamfering area while the concrete, if overflowed, is removed. In the case when the strip is pressed, an oblique side of the strip is placed in contact with a long side 2 and a short side 3 with a cross section-L-shaped strip fixture 1 formed with the long side 2 and the short side 3 so that it may be pressed. More specifically, the fixture 1 is covered over the strip and pressed. In the case when the fixture is pressed, the long side 2 of the fixture is pressed along the side of a post or the like, thereby forcing equal force to act on the chamfering area.  A handle 9 is provided on the fixture 1 so as to contrive the convenience of handling. This construction make it possible to adjust the chamfering area with efficiency.

Title: Monitor and control system
Inventor: MURAKAMI KEISUKE
IPC: H04Q9/00
Filed: 1993-12-29
Abstract: PURPOSE: To shorten the polling time of the whole of a monitor and control system to improve the responsiveness by changing the length of a signal between a normal case and the other case and including the signal indicating the length of a return signal at the beginning of return data. CONSTITUTION: A time-division multiplexed signal is sent from a central monitor and control part 1 to a transmission line 2. Each of terminals 3 to 6 sends the return signal based on information to be returned from the terminal itself synchronously with the return time if address data in transmission data received through the transmission line 2 coincides with its own peculiar address data. A two-bit signal is used as the return signal in a normal case, and a 9-bit signal is used as it in accordance with its degree of urgency at the time of the occurrence of abnormality. In the normal monitor state, two-bit signals are returned from terminals 3 to 6 during polling, and the first bit is assigned to the signal for discrimination which indicates the length of data to be returned following it.  Thus, two bits are enough for information of abnormality presence/absence, and the polling time is shortened.

Abstract: PURPOSE:To provide method and apparatus for weighing chemical easily and accurately in cleaning equipment. CONSTITUTION:In an equipment for cleaning a semiconductor wafer using various chemicals 2, level of chemical 2 in a weighing tank 1 is regulated substantially at a set level when the chemical 2 is weighed using the weighing tank 1 with excess chemical 2 being sucked through a capillary tube 7 suspended from above the weighing tank 1. Level of the chemical 2 in the weighing tank 1 is regulated substantially at a set level through the use of an overflow pipe 5 or the like. Subsequently, excess chemical 2 in the weighing tank 1 is sucked through the capillary tube 7 thus sustaining a constant level of the chemical 2. Since the chemical 2 is sucked through the capillary tube 7, level of the chemical 2 can be regulated finely without causing any waving and thereby the chemical 2 can be weighed with high accuracy.
