Title: Semiconductor memory
Inventor: KUBO TAKASHI
IPC: G11C7/00
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To obtain the constitution of a semiconductor memory which enhances the usage efficiency of a data bus and in which input/output data having a wide band width can be handled at a high speed. SOLUTION: Serial write data equivalent to a burst length portion to be transmitted to a data bus are stored in parallel in latch circuits 74a to 74d by an S/P data conversion circuit 70. In a memory cell array 50, one memory cell row and four memory cell columns are activated simultaneously. By a sense amplifier I/O circuit 60, bit lines BL1 to BL4 and the latch circuits 74a to 74d are connected respectively, and the write data having the burst length portion are written collectively in the memory cell array. Read data which are read out collectively in the burst length portion by the memory cell array 50 are converted into serial data by a P/S data conversion circuit 80 so as to be transmitted to the data bus.

Title: Centrifuge for cleaning blood corpuscle
Inventor: YAMADA KENJI
IPC: B04B5/00
Filed: 1981-07-13
Abstract: PURPOSE:To enable the release of supernatant liquid out of a test tube by centrifugal force, by retaining a test tube holder in a vertical position by the repulsive force between a magnetic element fitted to the upper part of the circumference of a retainer and a magnetic element provided at the test tube holder. CONSTITUTION:Red corpuscles are put in a test tube 6, the tube is fitted to a test tube holder 4, and a rotor 3 is rotated. Then the test tube holder 4 is retained at a position shown by an alternate long and two short dashes line by centrifugal force. Under the condition, a physiological salt solution is injected from a nozzle 8 and mixed with the red corpuscles, and thereby cleaning is performed. Thereafter the rotor 3 is stopped, and a retainer 9 is moved upward by exciting an electromagnet 11. Then, the test tube holder 4 is held in a vertical position by the repulsive force between magnetic elements 5 and 10. The rotor 3 is rotated in this state to release supernatant liquid out of the test tube 6. All of these operations can be made automatically, and thus the supernatant liquid can be released automatically with excellent reproducibility.

Title: Magnetic head
Inventor: KOJIMA TAKAYUKI
IPC: G11B5/255
Filed: 1982-06-28
Abstract: PURPOSE:To suppress the increase in the viscosity of a fixing material which fixes a magnetic core to a case and to improve the castability of the fixing material by adding at least an org. lubricant and a reactive diluent into the fixing material. CONSTITUTION:At least 1 kinds among the so-called metallic soaps [(RCOO)nM] consisting of metallic salts (Na, Ca, Mg, Ba, Li, Al, Zn, Fe, Cu, Pb, Sn salts) of higher fatty acids such as, for example, stearic acid, oleic acid, palmitic acid or the like are used as an org. lubricant in a fixing material consisting essentially of an epoxy resin, hardener, filler, and org. lubricant. Since a reactive diluent is a compd. of a low mol. wt. having at least one epoxy group in a molecule, the same can be cured by a hardener as well as an epoxy resin; therefore, the hardener needs be increased in amt. from the epoxy equiv. as much as the reactive diluent is added. Thus, the chief material contg. the reactive diluent and the hardener increased in amt. by as much as needed for curing the reactive diluent are used by mixing in casting to a magnetic head; therefore, the other components except the filler increase as a whole of the fixing agent, thus resulting in the lower viscosity and easier casting operation.

Title: Vertical welding method for cr-mo steel
Inventor: MIURA YUZURU
IPC: C21D9/50
Filed: 1987-05-06
Abstract: PURPOSE:To prevent weld metal from cracking and to improve its toughness by providing a high-speed heating means in the rear of a welding electrode to heat the metal above the specific temperature at the specific heating speed. CONSTITUTION:In the case of performing the vertical welding on a Cr-Mo steel member 1 using the gas shielded arc welding electrode 2, the high-speed heating means 3 is arranged in the rear of the electrode 2 at the time of welding a last layer to heat the weld metal rapidly. At this time, the heating speed of a heating source 3 is made to >=200 deg.C/min and the weld metal is heated up too the temperature above an AC3 transformation point (720-800 deg.C). Since the last layer weld metal 4 is heated to raise the temperature rapidly up to a recrystallization temperature range of the extent of 800-950 deg.C, the occurrence of the cracking of the weld metal 4 is prevented and its structure is made fine. By this method, the occurrence of the cracking of the weld metal 4 is prevented and its toughness is improved.

Title: Bar code reading method for bar code system
Inventor: TAKAHASHI MINORU
IPC: G06K7/015
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a bar code reading method capable of easily recognizing the information of a bar code system without selecting the direction of the bar code system. SOLUTION: In the bar code system in which three reference points are provided at prescribed intervals at orthogonal positions and the information area of 4 bits extending orthogonally is provided at a position sandwiching these reference points, the information of the bar code system is fetched as a binary signal by a CCD camera 12, the areas and centroid positions of respective detected images are calculated from the binary signal and three reference points are detected out of these images. Further, an information area to detect a bar code regardless of the attitude of the car code system is fixedly located from a line segment extended from an intermediate position between two reference points at the most separated positions to the remaining reference point and a line segment orthogonal to this line segment.  Consequently, these are merits that not only the presence/absence of the bar code in the information area can be surely detected regardless of the direction of the bar code system but also the information area to detect the bar code can be located and that the information of the bar code system can be easily identified.

Title: Overhead projector
Inventor: OMURA HIROSHI
IPC: B41J3/46
Filed: 1987-05-06
Abstract: PURPOSE:To effectively execute overhead projection by carrying a recorded recording medium on a Fresnel plate by means of a carrying device incorporated in a projector and projecting pictures in leaving the position of a secondary original as it is at the time of completing recording. CONSTITUTION:When rollers 22a and 22b evacuate a primary original from a cover 20 and rollers 8a and 8b feed a thermosensitive clear sheet 7 by a certain quantity, a sequence control circuit transmits a signal to a stepping motor control circuit so as to stop a motor and then the sequence of generating the secondary original is completed. If a pole brace and a projecting head part 2 are raised with action opposed to folding action and a clip stop is executed, a projecting state is obtained, as it is. Namely, since the thermosensitive clear sheet 7 is placed on a mirror Fresnel plate 10 to be in the projecting state, the picture of the primary original 21 copied on thermosensitive clear sheet 7 can be projected if the lamp 33 of the projecting head part 2 is made to emit light.

Title: Shutter for disc cartridge
Inventor: SAKURADA MASATAKA
IPC: C08L23/00
Filed: 1993-05-12
Abstract: PURPOSE:To allow formation of a shutter of disc cartridge using a resin mate rial having a low shrinkage percentage and high dimensional stability after molding, i.e., an olefinic resin. CONSTITUTION:The shutter 16 of a disc cartridge 10 is molded using a cyclic polyolefin having a specific gravity of 0.99 or above and a shrinkage percentage of 0.8 or below. The cyclic polyolefin includes ethylene-tetracyclododecene copolymer, ethylene-bicycloheptene copolymer, ethylene-tricycloundecene, etc. The shutter molded using such resins provides good sliding without producing fine powder due to abration thus preventing erroneous function of disc due to fine powder.
