Title: Gelatin gel resistant to warm water
Inventor: NAKURA MASANORI
IPC: A23L29/20
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To obtain a gelatin gel which is excellent in resistance to warm water (mechanical strengths) at the temperature of a living body by adding a polycarboxylic acid to gelatin and heating it to introduce chemical crosslinkages into it. SOLUTION: Preferably, the amount of a polycarboxylic acid added is such that the amount of COOH groups in the polycarboxylic acid is 0.2-2.0 mol based on the total amount of amino acid residues: Gln, Asn, Glu and Asp, and the temperature of heat treatment is in the range of 60-130 deg.C. Succinic, adipic, and citric acids are preferable as the polycarboxylic acid. A preferable gelatin gel has a swelling ratio lower than 1.0.  The swelling ratio is defined by the formula: [Sc(40)/Sc(30)]/[Sh(40)/Sh(30)], wherein Sc is the degree of swelling of a chemically crosslinked gelatin gel; Sh is the degree of swelling of a thermally crosslinked gelatin gel; the figures in the parentheses are each the water temperature at which the degree of swelling is measured; and Sc and Sh are each calculated by the equation: S=(Ws-Wd)/Wd (wherein Ws is the wt. of gelatin gel at its equilibrium swelling; and Wd is the wt. of the gelatin gel in the dried state).

Title: Information storing device
Inventor: OTSUBO TADASHI
IPC: H04N19/00
Filed: 1994-02-10
Abstract: PURPOSE:To provide an information storage device capable of reducing circuit scale of a reproducing system when plural systems of signals data compressed and recorded by predictive encoding are reproduced simultaneously. CONSTITUTION:The signal encoded by a predictive encoder provided with a local decoder 1 is recorded on a track on a recording medium by a recording/ reproducing optical system 18. At the time of reproduction parts different from each other on the recording medium are reproduced together by the recording/ reproducing optical system 18 and an erasing/reproducing optical system 30, and are decoded separately by an exclusive decoder 2 and the local decoder l, and two systems of reproducing output signals are obtained. Thus, by using the local decoder incorporated in a recording processing system to compress data by the predictive encoding as the decoder in a reproducing process system, the circuit scale of the information storage device capable of performing a high-degree editing processing with two systems of reproduction is reduced.

Title: Semiconductor memory device
Inventor: YONEYAMA AKIRA
IPC: G11C11/409
Filed: 1990-01-26
Abstract: PURPOSE:To reduce bit line capacity by providing a precharging MOSFET between intermediate power supply and an input/output line, and precharging a bit line through the input/output line. CONSTITUTION:When it comes to a precharging period, an equalizing MOSFET QBE connected to the bit lines BL, *BL, the equalizing MOSFET QIOE and the precharging MOSFET QIOP connected to I/O, *I/O are turned ON. Therefore, the bit lines BL, *BL are equalized by the MOSFET QBE, and their voltage becomes close to VCC/2. Besides, the I/O, *I/O are equalized by the MOSFET QIOE, and simultaneously, they are precharged by the MOSFET QIOP, and their voltage becomes close to VCC/2. At that time, a column address decoder CADEC turns ON all selecting MOSFETs QC so as to precharge the bit line not having reached VCC/2. Thus, the precharging MOSFET to be connected to a pair of the bit lines becomes unnecessary, and the bit line capacity can be reduced.

Title: Image forming device
Inventor: MIZUISHI HARUJI
IPC: G03G15/02
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of staining on the rear side of a paper sheet with toner, even if a transfer roller in contact with a photoreceptor is used as a transfer device. SOLUTION: The transfer roller 20 is cleaned in such a manner that a bias is applied to the transfer roller 20, in a state where the bias is applied to an electrifying roller 2. Further, the electrifying roller 2 is cleaned with frictional force by a cleaning pad 25 brought into contact with the electrifying roller 2, after the transfer roller 20 is cleaned. Therefore, at the time of cleaning the transfer roller 20, the bias is applied to the electrifying roller 2, so that the photoreceptor 1 can be destaticized to prevent the toner from sticking to the surface of the photoreceptor 1 from a developing device 3. Since the electrifying roller 2 is cleaned with the above timing, the toner scraped from the electrifying roller 2 can be prevented from sticking thereto again.

Abstract: PROBLEM TO BE SOLVED: To visually display whether shock to a foot is effectively absorbed during use or not and to display the timing to exchange footwear by arranging a lining composed of a material for absorbing shock on a shock absorbing member to be used for the inside of footwear having the internal part for holding the foot of wearing person. SOLUTION: An inner sole 34 is made of thick fabric and patterns can be formed on an upper surface forming the inside of shoe. Before adhering the outside edge part of inner sole 34 to filling 32 by an adhesive agent, it is sewn to the lower edge of upper part 24 and a foamed inner pad 50 is held on the upper surface of inner sole 34 so that shock to the foot of wearing person can be further absorbed. The upper part 24 is equipped with an outside shell 52 and a lining 54 composed of fabric and the lining 54 is adhered inside the outside shell 52 so that one part of foot can be covered while the foot is housed on the shoe sole 22.  Since the foamed material of intermediate layer 84 lowers its elasticity and a tongue part 80 loses shock absorbing property for the foot after use for a long time, the wearing person periodically checks the tongue part 80 to evaluate whether or not the footwear is to be exchanged.

Abstract: PURPOSE:To reduce the number of switching transistors as a signal grounding control means for each drive coil to half the required number of conventional transistors by applying a drive current to each drive coil corresponding to one array of printing means and the other at varying timing. CONSTITUTION:A printing head 10 has two arrays of line heads H1, H2. Ham mer pins (H11,...,H1n), (H21,...,H2n) of each array H1, H2 are paired with each hammer pin opposed to one end of each one of the former at the same position. Then these pairs are sequentially divided into 'n' number of groups. After this, the drive coils, e.g. L11 and L21 of each group are commonly earthed through a single switching transistor 801. The waveform of a signal running through the drive coils L11, L21 is delayed in timing by a single waveform. For this reason, signal currents of both coils never run to the switching transis tor 1 in an overlapped form, so the same capacity of the coil as the conventional one is acceptable. The same is true about the drive coils of other groups. Also the signal current to be output from a signal power supply has a peak value which is half the value ever shown by the conventional cases.

Abstract: PURPOSE:To prevent the deterioration of the response time of a programmable controller by rewriting only the program that is accordant with the prescribed number of addresses (steps) within a fixed scan time at addition or deletion of programs and performing the adding or deleting operations of all programs in plural scan times. CONSTITUTION:A program (j) is stored in the final address (n+9) of the addresses storing the programs (a)-(j) respectively for each instruction in the present one step. Then the program (j) is rewritten into a rear address (n+10). Hereafter the program (i) of an address (n+8) and the program (h) of an address (n+7) are rewritten into the addresses (n+9) and (n+8) respectively in each step. Then a non-execution instruction (NOP) is written into the head address (n+6) of an unchanged block. Thus the rewriting actions are through in a scan mode. As a result, one scan time is never increased and the deterioration of the response time is avoided for a programmable controller.
