Title: Freezing method of refrigerating mold
Inventor: NAGAO SHIYOUZOU
IPC: B22C9/12
Filed: 1979-06-27
Abstract: PURPOSE:To improve the productivity of a refrigerating mold by molding the molding sand containing moisture in a molding flask, leading a cooling medium into the molding flask and freezing and setting the same in a state of local cooling. CONSTITUTION:Molding sand 4 containing moisture is molded to a specified shape in a molding flask 1 for casting. During the progression of this molding or upon completion of the same, a cooling medium such as liquid nitrogen is led to cooling medium supply means 2 constituted by straight pipes 2a and ring pipes 2b and is blown into the molding sand 4 through the blow-out port. Thereby, the molding  sand 4 is frozen at an early time from the outside surface side to the inside surface  side and is set in the specified mold shape. With this method, the cooling efficiency  of the cooling medium becomes high and it becomes possible to economically produce the refrigerating mold by the integral work continuous to the molding process  without moving the mold.

Title: Color photosensitive silver halide material
Inventor: ICHIJIMA YASUSHI
IPC: G03C7/26
Filed: 1983-05-11
Abstract: PURPOSE:To improve the shelf stability and color reproducibility by incorporating a compound represented by a specified structural formula. CONSTITUTION:A compound represented by formula I is incorporated. In the formula, A is a group capable of releasing Nu-PUG-E after a reaction with the oxidized product of a developing agent, PUG is a photographically useful group, Nu is a nucleophilic group contg. N, O or S as a nucleophilic central atom or a precursor of the group, and E is an electrophilic group having three-dimensional positional relation enabling an intramolecular nucleophilic reaction accompanied by the formation of a 3- or 7-membered ring with the nucleophilic group Nu after Nu is cleaved from A. The Nu-PUG-E releasing speed of the compound can be regulated in accordance with the kind of Nu bonding to A. A compound which is produced when the part of the electrophilic group E is hydrolyzed is A-Nu-PUG, and this compound is not diffused by providing diffusion resistance to A. Accordingly, the photographically useful group can be released at an arbitrary time without changing the degree of influence on the photographic properties, and the shelf stability is improved.

Title: Determination of creatinine
Inventor: KASAHARA KAN
IPC: G01N33/70
Filed: 1980-06-18
Abstract: PURPOSE:To speedily and accurately measure the amount of creatinine independently of the coexisting bilirubin when the creatinine in a body fluid is determined by using picric acid, by a method wherein a sample is oxidized by using periodic acid (periodzate), and the excess oxidizing agent is treated with an aminoalcohol or the like. CONSTITUTION:In the diagnosis on a kidney disease or the like, when the creatinine in a body fluid such as flood, urine or the like is to be determined, a sample is oxidized in an NaOH or Na2CO3 solution containing periodic acid (periodate) or an alkaline buffe solution containing phosphate. Then, a picric acid solution containing 0.05-5% an aminoalcohol such as mono- or triethanolamine is added thereto, and the absorbance is measured with a wavelength of 490-530nm in a constant temperature bath at 37 deg.C. The amount of creatinine in the sample is obtained from the calibration curve obtained through the same operation using a standard sample. Thereby, the bilirubin in the sample is decomposed through oxidation so as to have no effect on creatining, and the excess oxidizing agent is decomposed by means of th aminoalcohol and removed. Accordingly, the amount of creatinine can be readily measured by an automatic analyzer.

Filed: 1978-07-07
Abstract: PURPOSE: To obtain always optimum exposure irrespective of the speed of depresssing a shutter button by providing a timer circuit which actuates when a power source switch goes ON to a release mechanism.  
     CONSTITUTION: When a power source switch 7 is turned ON by the half-push of a shutter button 3, the pulse signal produced in the connection point 23 is sent to a flip-flop circuit 27 to reset this. When the shutter button 3 is further half-pushed, a start switch 9 goes ON and the potential of the connection point 25 lowers down to "L". On the other hand, the foregoing pulse signal is delayed by the specified time in a timer circuit 26 and is inputted to the flip-flop circuit 27 to set this, then the output terminal Q becomes "L". As a result, a sequence control circuit 29 is started through NOR circuit 28 and the specified operation is accomplished. In this way, always optimum exposure may be obtained irrespective of the speed of depressing the shutter button.

Title: Semiconductor integrated circuit device
Inventor: GOMI HIROSHI
IPC: H01L27/04
Filed: 1990-03-31
Abstract: PURPOSE:To contrive a reduction leakage between circuit wirings and to contrive an increase in the integration of the title device without increasing relatively the layout areas of the wirings by a method wherein when first and second transmission lines are wired, a third transmission line of a low impedance is wired on an intermediate wiring layer. CONSTITUTION:When a transmission line L1 is wired on a first-layer wiring layer A and a transmission line L2 is wired on a third-layer wiring layer C in parallel to the line L1, a transmission line 3 on a second-layer wiring layer B, which is functioned as a reference potential of a DC or GND transmission, is wired between the lines L1 and L2 in parallel to the lines L1 and L2. According to this structure, as the lines L1 and L2 are respectively shielded by the line L3, a parasitic capacitance between the lines L1 and L2 can be reduced, whereby a leakage between the transmission lines can be prevented from being generated. Moreover, as the L1, L2 and L3 are all wired in parallel, the area of a pattern is hardly increased. Moreover, the interval between the L1 and the L2 can be made narrower compared to the case of that of a two layer wiring. When the width of the line L3 is made wider than those of the lines L1 and L2, the leakage can be made less.

Title: Anticorrosive r-fe-b bonded magnet and manufacture of the same
Inventor: YOSHIMURA MASAYUKI
IPC: H01F1/08
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an anticorrsive R-Fe-B bonded magnet, including an optimum industrial process, for providing an anticorrosive coating with high contact strength and good dimensional accuracy on the surface of a porous R-Fe-B bonded magnet, where a plating solution and a cleaning solution are prevented from entering and remaining. SOLUTION: A R-Fe-B bonded magnet is subjected to barrel abrasion by a barrel device using a dry method using Al fine pieces such as spherical, block- like, or needle-like (wire) shapes having predetermined dimensions as a medium, and the crushed Al fine pieces are applied under pressures to a resin surface and a sealing hole part on the surface of the bonded magnet. The Al fine pieces are also applied to the magnetic powder surface, and zinc substitution processing is carried out for preventing the dissolution of Al at the subsequent electroplating. Thus, high conductivity can be imparted by forming an Al coating film on the surface of the R-Fe-B bonded magnet, so that a fine electrolytic plating layer having no pin hole can be formed.

Title: High frequency doubler circuit
Inventor: HIGUCHI YOSHIO
IPC: H03B19/14
Filed: 1994-04-21
Abstract: PURPOSE:To perform a multiplication of high frequency by 2 by the use of a simple circuit configuration and in a state where a minute signal level is maintained by setting the operating point of a transistor at a specific point. CONSTITUTION:A high frequency doubler circuit consists of the capacitors C1 to C4, the resistances R1 to R3, a coil L and a transistor TR Q. The operating point of the TR Q is set at a point near the maximum value of the secondary differential coefficient of a curve that shows the relation between the base voltage and the collector current of the TR Q. When a distortion that is asymmetrical to the source signal sent from a high frequency signal source 11 is caused to the TR Q, the TR Q generates higher harmonics multiplied by even numbers. A tuning circuit 13 is connected to the collector of the TR Q, and the tuning frequency of the circuit 13 is set to be 2 times high as that of the source signal. Thus a signal obtained by doubling the source signal in frequency is outputted from the collector of the TR Q.
