Filed: 1981-10-08
Abstract: PURPOSE:To decrease the number of gates unnecessary logically in a mounted level and the number of input and output terminals, through the reduction in a delay time and reflection distortion, by effectively using an input and output buffer gate arranged around one mounting level of a logical device. CONSTITUTION:A logical device consists of a multi-chip package 111 having a source circuit 112, a load multi-chip package 121 having a load circuit 122 in the vicinity, and a load multi-chip package 131 at a remote location having a load circuit 132. On a printed circuit board around the package 111 at the source, two buffer gates 701 are arranged and the gates 701 drive the packages 121 and 131 one by one. A termination resistor 144 connected to a power supply 141 is connected to the circuits 112, 122 and 132. The delay in the wiring is decreased as the propagation time for one way of wrings 702 and 703 and the construction of wiring is taken as 1:1, allowing to reduce the reflecting distortion.

IPC: G11B5/706
Filed: 1981-10-08
Abstract: PURPOSE:To uniformalize the frequency characteristics in recording and reproduction by forming a continuous thin film of ferromagnetic iron oxide contg. Co on a disklike substrate while doping the thin film with Co so as to increase the coercive force of the resulting magnetic body toward the inside along the radial direction of the body. CONSTITUTION:A sintered Fe3O4 body as a target 4 is mounted on a disklike Al alloy substrate 1. The semicircular part of the circular target 4 on the substrate side is doped with 3% Co and the remaining half is not doped with Co to form a substrate 1 for a recording body composed of Fe3O42 doped with Co and undoped Fe3O43. While rotating the substrate 1 at 17r.p.m. as shown by the arrows, sputtering is carried out. By oxidizing the sputtered material at 290 deg.C in the air, a recording body 1 forming a continuous thin film of gamma-Fe2O3-base ferromagnetic iron oxide is obtd. The Co content of this circular target plate 10 is continuously reduced from the inside toward the outside to increase the coercive force toward the inside. Thus, a magnetic disk with uniformalized recording and reproducing characteristics is obtd.

Title: L-ascorbic acid derivative and its production
Inventor: YOSHINAGA MASANOBU
IPC: C09K3/00
Filed: 1996-06-01
Abstract: PROBLEM TO BE SOLVED: To obtain an L-ascorbic acid derivative, useful for producing an oxygen-removing polymer excellent in water resistance, solvent resistance and oxidation resistance. SOLUTION: This L-ascorbic acid derivative is expressed by formula I or formula II. A derivative of formula I can be obtained by dissolving a 4vinylbenzoic acid in a concentrated sulfuric acid and adding Lascorbic acid to the resultant solution to esterify the hydroxyl group at the 6-position of the L-ascorbic acid with 4-vinyl benzoic acid. Further, a derivative of formula Hcan be obtained by dissolving L-ascorbic acid in a basic solvent, dropping 4vinylbenzenesulfonyl chloride to the resultant solution to convert the hydroxyl group at the 6-position of the L-ascorbic acid to 4vinylbenzenesulfonyl. By these processes objective compounds can be easily produced without using an enzyme or an acid chloride. An oxygen-removing material having excellent oxygen-removing function can be produced by using an oxygen-removing polymer obtained using one of the objective compounds as a monomer.

Filed: 1982-09-16
Abstract: PURPOSE:To protect the overcurrent of a power source by controlling a current which flows to switching transistor on the basis of the mean current and the instantaneous current at the primary side of the transformer. CONSTITUTION:When an abnormal current flows through any of output terminals 100-10n, the output pulse width of a pulse width modulator 1 becomes wide to maintain the output voltage constant, and a current which flows to the primary side coil of a switching transistor 4 increases. This current is smoothed by a current smoothing condenser 12 and flowed to a mean current detecting resistor 7a, thereby increasing the voltage difference at both ends. Further, the maximum value of the current which flows to the instantaneous current detecting resistor 7b increases. The maximum value of the voltage which is inputted to a peak holding circuit 13 increases at the voltage corresponding to the amount added with the increased component of the instantaneous maximum current to the increased component of the mean current. This voltage is converted to a DC and fed through a current detector 3 to the modulator 1.

Filed: 1995-06-28
Abstract: PURPOSE: To enable a dehumidifying to be attained without decreasing an indoor temperature by a method wherein a temperature of an auxiliary indoor heat exchanger may become less than a dew formation temperature of sucked air as a temperature of a main indoor heat exchanging ventilation air approaches a detected temperature so as to perform a dehumidifying operation. CONSTITUTION: A degree of opening of an electromotive expansion valve 24 is controlled in such a way that a temperature of a main indoor heat exchanger 8 detected by a heat exchanger temperature sensor 14 may approach a suction air temperature detected by an indoor temperature sensor 15 and further a temperature of an auxiliary indoor heat exchanger 7 detected by a heat exchanger sensor 13 may become a target value less than a dew formation point of the sucked air. For example, if the detected temperature is higher than the target value, a degree of opening of the electromotive expansion valve 24 is reduced by a predetermined value for every control loop and in turn if the value is lower than the former value, a degree of opening of the electromotive expansion valve 24 is increased by a predetermined value for every control loop.  With such an arrangement as above, it is possible to perform a dehumidification with no reduction in indoor temperature without requiring any electrical heater.

SOLUTION: A CDMA(code division multiplexing access) code allotting device 2 allots CDMA codes to sound signals A, B and C from plural sound sources 1a, 1b and 1c, and forms signals including respective codes. After these signals are multiplexed by a multiplexing device 4, a sound recording device 5 records it in a digital source 3. In the case of editing, an editing device 11 discriminates the desired signal from the multiplexed signal recorded in the digital source 3 by using a CDMA code allotted to the desired signal, extracts it, and performs the editing. In the case of reproduction, a reproducing device 7 discriminates the desired signal from the multiplexed signal recorded in the digital source 3 by using the CDMA code allotted to the desired signal and extracts it to perform reproduction.  Thereby, even after signals are multiplexed and recorded, they can restore to each signal before multiplexing, thus only the desired signal can be extracted, edited and reproduced.
