Title: Separation membrane
Inventor: URAMOTO HIROSHI
IPC: B01D71/44
Filed: 1990-03-12
Abstract: PURPOSE:To obtain a separation membrane having the good selective adsorbing capacity of an org. acid such as phenol by mixing an olefinic resin with a crosslinked polyvinyl pyridine resin and forming the resulting mixture into a sheet. CONSTITUTION:A polymerization initiator is added to a mixture of vinyl pyridine and divinyl benzene and the mixture is subjected to suspension polymerization to prepare a polyvinyl pyridine resin having a crosslinked structure. Next, an olefinic resin such as polyethylene or polypropylene is added to this resin to be mixed therewith and the resulting mixture is heated and melted to be molded into a sheet. Since the separation membrane thus obtained has the crosslinked polyvinyl pyridine resin therein, this separation membrane can be enhanced in the selective adsorbing capacity of an org. acid such as phenol and easily prepared industrially.

Title: Automatic performance electronic musical instrument
Inventor: KANEKO SHIGEHIKO
IPC: G10H1/00
Filed: 1978-05-23
Abstract: PURPOSE: To surely prevent input errors of pitch information by letting input sound be immediately produced at the time of inputting the pitch information through keyboard operation into the musical instrument built-in with a memory device.  
     CONSTITUTION: When the key switches S n-1 , S n-2  of two circuits which are mutually cooperatively closed for each key are closed by operating the (n)th key, the pitch information is sent from the switch S n-1  to an encoder 2, whereby it is coded a and is then applied to a memory 3. The signal from the switch S n-2  is applied to an oscillator 4, and therefore if the oscillator 4 is constituted by divider chain or voltage control type and is oscillated at the frequency corresponding to the switch S n-2 , an output appears from the oscillator 4 each time when one pitch information is inputted by operating a keyboard 1. This output is sounded through an amplifier 5 and a speaker 6. Since this lets the pitch information be immediately confirmed, its input error may be surely prevented.

Title: Magnetic disk cartridge
Inventor: KANEMITSU CHIHIRO
IPC: G11B23/00
Filed: 1987-03-19
Abstract: PURPOSE:To reduce an error rate in the high density of recording by allowing the specified range of the whole circumference length of a part where a hub and a magnetic disk are brought into contact not to adhere to an adhesion means. CONSTITUTION:In a magnetic disk cartridge of which metallic hub 4 adheres to the magnetic disk 6, the 10-75% range of the circumference of the hub 4 in the adherent part of the disk 6 is made to a non-adhesion part. Therefore peeling from the hub 4 of the magnetic disk, transformation caused by the friction with a head and distortion generated by the rigidity of the inner circumference part of the disk 6 are prevented by discontinuously executing the adhesion processing at the part where the metallic hub 4 and the magnetic disk 6 are brought into contact or the plural partial adhesion processing there when head load is executed. Thus the soft error can be reduced.

Title: Belt for twin belt caster
Inventor: NAKAMURA YUJIRO
IPC: B22D11/06
Filed: 1988-03-18
Abstract: PURPOSE:To reduce the thermal deformation of a belt, to prevent the crack generation on the cast billet surface and to improve the quality by coating a lubricant on a belt and executing knurling on the belt surface of the contact side with a molten metal. CONSTITUTION:A graphite lubricant is coated on the surface of a water cooling belt 3 prior to casting and during casting of a molten metal and this lubricant is stuck to the head of a roulette/pattern 12 and imbedded into the root area as well at the same time. An air bubble and gap are formed on the coating film of the lubricant filled in the root area to fill no root area. The heat transfer of cast billet and water cooling belt 3 is performed through the lubricant at the head part of the roulette/pattern 12 and insulated at the root area, hence the cooling of the belt 3 is eased for the cast billet and also the thermal load onto the belt 3 is drastically reduced.

Title: Pcm converter
Inventor: INANAGA KIYOFUMI
IPC: H04R1/00
Filed: 1983-04-11
Abstract: PURPOSE:To obtain a PCM converter where the characteristic is not deteriorated and the error is scarcely generated by constituting one plane electrode of a piezoelectric elemnt of many electrode parts extending from one end side to the other. CONSTITUTION:A driving part 13 consisting of a piezoelectric element body 12 is fixed to a supporting material 14 by one end side 13a of plane electrodes 11A and 11B, and the other end side 13b is a free end. Parallel electrode parts a1-a7 are connected to lead wires b1-b7 so that they are arranged in positions, which are hardly displaced, in the fixed end side 13a. Consequently, since lead wires are arranged in positions, which are hardly changed, in the fixed end side 13a in parallel electrode parts a1-a7, lead wires do not affect a mechanical load for oscillation, and the characteristic is not deteriorated. Since parallel electrode parts extend from one end side 13a of the driving part 13 to the other 13b, the oscillatory displacement due to an applied bit signal is transmitted directly to the other end side 13b of the free end, and therefore, the area of parallel electrode parts and the oscillation driving force for displacement are matched to each other approximately to generate hardly the error.

Filed: 1984-03-31
Abstract: PURPOSE:To reduce both the size and power consumption of a memory which is suited to an application system by defining 8 bits equal to the unit word length of an 8-bit microprocessor as one word and storing a memory having the storage capacity of 64K words equal to an address space of the microprocessor into a package. CONSTITUTION:A memory having the storage capacity of (8 bitsX64K words) is stored to a package 13 containing data input/output terminals 141 and 148 for input/output of data D0-D7. These data can be written and read for each word. Furthermore the package 13 contains address input terminals 151-1516 for input of address signals A0 and A15. Thus an optional one can be selected out of 64K words and therefore 8 bits can be written and read in parallel to each other. In addition, the storage capacity is also set at 64K bytes suited to the address space of a microprocessor. Thus a main memory of a system can be formed with a single memory.

IPC: F02D35/00
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To minimize the number of exhaust emission sensors, while making early activation of the exhaust emission sensors possible in a multi-cylinder engine equipped with a collective exhaust port. SOLUTION: A collective exhaust port 18, provided in a cylinder head 12, consists of exhaust ports 46 which extend from exhaust valve holes 35 of each cylinder and an exhaust collective portion 47, at which the exhaust ports 46 are collected. A detection portion 422 of an oxygen concentration sensor 42 is installed facing the exhaust collective portion 47, which enables detection of oxygen concentration in exhaust emission discharged from multiple combustion chambers by the commonly used exhaust emission sensor 42. Therefore, the number of the exhaust emission sensor 42 can be kept to a minimum. Also, since the position of an oxygen concentration sensor 42 approaches close to the combustion chambers, the temperature of the oxygen concentration sensor 42 can be quickly raised for activation by the heating of the exhaust emission at a high temperature.

Abstract: PURPOSE:To miniaturize the circuit by generating an approximate moving average value by subtraction from input data while using the average value of samples up to the last time. CONSTITUTION:When the input data are defined as XK+N+1 and output data are defined as YK+N+1 at the time of the same sample, data to be applied from a divider 3 to a subtracter 1 are output data YK+N at the time of the last sampling (this value itself is the moving average value for a number N of times for sampling up to the last time), the input data and the output data at the time of the last sampling are subtracted by the subtracter 1, and data xK+N+1- yK+N are outputted. At a complete integrator 2 (an adder 21), the output data of this subtracter 1 are added to data SIGMAxi(i=k,...,K+N) integrated just for the prescribed number of sampling up to the last time, the output data are delayed just for one sample by a latch circuit 22, and the data are applied to the integrator 2 for the next addition and applied to the divider 3. At the divider 3, the integrated data are turned to 1/N, and the output data are generated.
