Title: Production of l-biopterin
Inventor: KURONO MASATSUNE
IPC: C07D475/04
Filed: 1988-06-22
Abstract: PURPOSE:To readily and advantageously obtain L-biopterin by acting a sepiapterin reductase on 2-amino-4-hydroxy-6-(1'-hydroxy-2'-oxopropyl)pteridine as a synthetic raw material. CONSTITUTION:In producing L-biopterin by enzymatic process, 2-amino-4- hydroxy-6-(1'-hydroxy-2'-oxopropyl)pteridine is reduced by a sepiapterin reductase to effect stereospecific formation of L-biopterin alone. This, L-biopterin is a coenzyme for aromatic amino acid hydroxylases and finds broad applications as a BH4 precursor useful for drugs, also being inexpensive as a starting material for BH4 with small number of its synthetic steps as well as high yield.

Title: Printer
Inventor: HAMAGUCHI IWAO
IPC: B41J2/44
Filed: 1983-08-19
Abstract: PURPOSE:To print favorably without generating any feeling of incompatibility in the head arrangement, by a printer construction wherein a multiplicity of dot- forming elements driven in a partitioned manner and inclined in a staggered manner against a recording medium which is relatively moved. CONSTITUTION:The angle of inclination theta1 of LEDs is so set as to satisfy the relationship of the equation, wherein V1(mm./sec) is the linear velocity of a photosensitive material, t1 is the period of time required for sequentially driving the LEDs in a group, and L is the length of the LED. Where the head is used for a printer in which the linear velocity of the photosensitive material is V1, printing dots are arranged on a straight line. The dot-forming elements may be a PLZT photo shutter array or a liquid-crystal shutter array in a photo shutter array printer, or a thermal head array in a thermal printer. Accordingly, it is possible to print favorably, without changing the head, even when the linear velocity of the recording medium such as a photosensitive material is varied.

Title: Sheet for waterproofing
Inventor: TAJIMA TSUNEO
IPC: E04D5/10
Filed: 1995-05-26
Abstract: PURPOSE: To obtain a sheet for a waterproof purpose, which is applicable easily and surely to the building part of which the shape is complicated and which needs waterproof work, by a method wherein the adhesive strength of a self-adhesive layer is made in a state satisfying specified conditions. CONSTITUTION: A sheet for a waterproof purpose is formed by laminating a self-adhesive layer, a modified asphalt layer, and a granulate mineral layer. In this sheet, adhesive strength between the self-adhesive layer and the modified asphalt layer, and between the self-adhesive layer and an object being constructed is made strong enough to restrict at least elastic restoration owing to the residual strain of the modified asphalt. Furthermore, a reinforcing material layer having the rate of extension equal to or higher than the modified asphalt and having a modules equal to or lower than that is placed between materials formed of the asphalt layer.  A property of plastic deformation of the sheet is so formed that the rate of extension is 100% or higher, that the strength at that time is 200g/cm<2> or lower, and that a stress intensity of residual strain after one hour at the time when stress is relaxed in such a state that a rate of the extension, 100%, is applied is 60g/cm<2> or lower.

Title: Record input/output control system
Inventor: WATANABE MASAHIKO
IPC: G06F12/00
Filed: 1989-06-14
Abstract: PURPOSE:To decrease the number of access times to a file and to shorten the processing time by attaining the addition, the change and the deletion of records to a data buffer without having a direct access to an actual file. CONSTITUTION:When a command identification means 13 accepts a file open request, the control is shifted to the file open processing part of a command corresponding process means 14. Thus a log file 26 is opened and the records bearing the relative record Nos 1 - 514 are read out of the file 26 within a data buffer 25 as a buffer No.0. When the means 13 receives a read request for the record of a relative record No.200, the control is shifted to the record read processing part of the means 14. Thus the presence or absence of a designated record is checked within the buffer 25, and a calculation is carried out based on a flow. Consequently, the buffer No.0 is obtained as the record No.200 in the buffer 25. As the buffer No. of the record read in a file open process is equal to 0, the record of the No.200 is read out of the buffer 25 and sent back to a command requester 11.

In removing the plug 14 from the retained state, when a finger depresses a plug end 14a from a notch 9 provided at the lower wall, the tip of the other part of the plug 14b is projected by taking the outermost diameter 14c of the plug 14 as a fulcrum. Thus, the tip 14b of the plug 14 is nipped out.

Filed: 1994-07-05
Abstract: PURPOSE:To control the amt. of the strengthening particles to be added by mixing the strengthening particles with a cooling medium and injecting a mixture to the molten metal released from a nozzle, thereby making the molten metal finer. CONSTITUTION:The molten Al alloy 3 in a tundish 4 is released from the nozzle 5 into an injection chamber 2.
