Title: Address data inserting device
Inventor: MAEDA HIDEKAZU
IPC: H04N5/92
Filed: 1985-02-18
Abstract: PURPOSE:To decrease the crosstalk given from an FM modulation circuit in a period excluding the inserted recording period, by dropping the output of the FM modulation circuit for record of address data to the earth in the periods excepting a signal recording period for address data, etc. CONSTITUTION:The output of a buffer 28 is switched by a transistor TR61 and a recording current flows only in a high period of a gate pulse 6. This current is amplified by TR62 and 63 and flowed to a head 11 of a VTR, and the current flows in an amount just enough to be recorded on a VTR tape. Then the current is switched by a TR64 with the gate pulse, and an output terminal 8 is short-circuited to GND while the gate pulse is kept at low level. Then the VTR reproduction output is extracted to a reproduction amplifier circuit 50 through the head 11. The pulse 6 is set at a low level in an inserted recording mode of the address data. Thus switching circuits 1 and 30 are turned off and the signals equivalent to the address data are supplied to the head 11 from a recording driver 29. Then the address data is recorded on the VTR tape.

Title: Control valve for power steering device
Inventor: YAMADA AKIRA
IPC: B62D5/083
Filed: 1994-02-02
Abstract: PURPOSE:To restrain the occurrence of noise by accelerating the separation from a land part of a high-peed oil flow that flows along the land part through a supply passage into a valve body groove. CONSTITUTION:The pressure oil flowing into a valve body groove 23 through the throttled part 27 between the edge of an outside land part 24 where the gap has been narrowed and the chamfer 28a of an inside land part 28 becomes a high-speed oil flow or a jet (a) flowing along the surface of the inside land part 28. Since an eddy current (b) for pressing the valve body toward a valve shaft 22 is formed in the neighborhood of the side wall 23a, the distance of the jet (a) up to the point of separation where it is separated from the surface of the inside land part 28 is shortened, and the resistance is increased by the separation of flow, and the flow velocity is reduced, so that as compared with the case where a recessed groove is not formed in the side wall 23a, the high- speed region of the jet (a) is shortened, and the occurrence of cavitation is reduced. Thus, the occurrence of noise can be restrained.

Title: Manufacture of positive electrode plate for alkaline storage battery
Inventor: KURATSUKA MAKI
IPC: H01M4/26
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a positive electrode plate, in which cobalt hydroxide at a high level can be filled and which can be utilized at high efficiency, by filing a nickel- sintered substrate with the active material, which is mainly composed of nickel hydroxide, and impregnating the substrate with cobalt after the formation treatment. SOLUTION: A porous sintered substrate, which holds nickel hydroxide as a positive electrode active material, is chemically formed once so as to form a cobalt hydroxide layer, which contains cobalt hydroxide at a high level, in a surface of the active material. Since the active material adhered to the surface of the electrode plate is eliminated and clogging of the surface of the electrode plate is eliminated, a cobalt hydroxide layer can be formed in the surface of the active material inside of the electrode plate. Nickel hydroxide at a level (2.2-3.0 value) higher than that of former nickel hydroxide (2.0 value) is obtained by chemical formation treatment so as to directly form cobalt hydroxide in the surface layer.  Nickel hydroxide and cobalt hydroxide at a level higher than the level thereof before the chemical formation treatment generates the oxidation-reduction reaction, and a part of the cobalt hydroxide is oxidized, and a high level cobalt hydroxide such as high conductive CoOOH is formed into a thin layer.

Filed: 1984-02-22
Abstract: PURPOSE:To enable shortening of a communication period for communication with the outside such as a center and an execution of an input operation and an output operation independently by constituting in such a way that an input unit can be separated from an output unit and can be coupled with the output unit. CONSTITUTION:A unit main body including an input unit 3 and an output unit 2 is constituted in such a way that the input unit 3 can be separated from the output unit and coupled with the output unit. In data processing, data inputted to the unit 3 are first stored in a memory 34. Then the unit 3 is coupled with the unit 2, and data of one transaction in the memory 34 is transmitted to a host computer 5 through a telephone set 4a, etc. Thus a center computer 5 executes the prescribed data processing and returns transaction data through a telephone line. Receiving this, the unit 2 stores them in a bubble memory 24. Thus transaction data is not printed instantaneously but printed after reception telegrams with respect to the entire transmission telegram are received and stored in the memory 24; therefore a communication period can be shortened and an input operation can be executed independent of an output operation.

Abstract: PURPOSE:To uniform the life of an opening/closing mechanism for hoppers and to improve the durability by counting the use frequency of every metering data and using metering data with a low frequency of use preferentially as data used for combinatorial arithmetic. CONSTITUTION:A controller 11 controls the driving of a dispersion feeder 3 and a supply feeder 4 and the opening and closing operation of pool hoppers 10 and metering hoppers 5, and also converts the metering signal of a metering mechanism 6 into weight to perform combinational arithmetic, and a hopper selection part 12 decides a combination. Counters 7 corresponding to the numbers of respective metering data are connected to the selection part 12 and counters 7 for the numbers of metering data selected as a combination are driven to count their frequencies. A deciding part 8 is connected to the counters 7 and decides the frequency of every counter 7 to determine the priority order. In this case, the probability that data with high priority are selected as a combination is high, so data with low frequencies are given priority to combine the data uniformly.
