IPC: H02J7/00
Filed: 1990-01-31
Abstract: PURPOSE:To reduce the discharging of a battery due to the consumed current for a charging and discharging device by a method wherein a second switching means is opened at all times when an operating unit detects that the battery is not connected to an electric appliance or a charger, however, the second switching means is controlled by the operating unit when the battery is connected. CONSTITUTION:When a charger or an electric appliance is not connected to a connecting terminal 2, charging current is not conducted through a current detecting resistor 3 and a microcomputer 4 detects that the charging or discharging current is not conducted through a battery pack 1 and opens the second switching means 10. On the other hand, when the charger or the electric appliance is connected to the connecting terminal 2, the charging or discharging current, conducted through the current detecting resistor 3, is amplified by an amplifying circuit 6 and is taken into the microcomputer 4 through an A/D converting circuit 7. In this case, the microcomputer 4 detects that the charging or discharging current is conducted through the battery pack 1 and reduces the opening time of the second switching means 10.

Filed: 1990-01-31
Abstract: PURPOSE:To lower the cost of a detector and to enhance the reliability thereof by adding the voltage induced in the secondary side output part of a differential transformer by the magnetic flux of a primary coil in the same or reverse phase with respect to the output of a secondary coil. CONSTITUTION:A coil 10 adding the voltage induced in the secondary side output part of a differential transformer 2 by the magnetic flux of a primary coil 3 to the outputs of secondary coils 4, 5 in the same phase or reverse phase is provided in series to the transformer 2. When acceleration/deceleration speed x is 0, the synthetic output voltage V on the secondary side is composed only of the voltage generated in the series coil 10 and V=V0 sin 2pi ft(f;power supply frequency) is formed. The synthetic output voltage when a movable magnetic body 6 receives acceleration to be displaced becomes V=(V0+Kx) sin 2pift(K; proportion constant). When the magnetic body 6 receives deceleration to be displaced, the synthetic output voltage becomes V=(V0-Kx)sin2pift. By passing the synthetic output voltage thus obtained through an amplifying circuit 11, a rectifying circuit 12 and a filter circuit 13, output voltage is obtained as V=V0+Kx(V0-Kx at the time of deceleration) in a final output means.

Title: Call setting control method for packet exchange
Inventor: EZAKI HIROSHI
IPC: H04L12/911
Filed: 1989-02-01
Abstract: PURPOSE:To set the packet transfer delay time to some value or below and to secure the communication quality by comparing and deciding a result of simulation using an average use rate of a multiplexing circuit and a measured value of queue length formed in an exchange. CONSTITUTION:In a high speed packet switched network, when a request for setting a call is generated from one of each terminal, an exchange inputs a measured value of queue length formed in a buffer in the own exchange, and also, inputs a measured value of an average use rate of a multiplexing circuit connected to the own exchange. Subsequently, the exchange executes a simulation of an M/D/I model in which an average use rate is an input value and derives queue length corresponding to the average use rate, and compares this value and the value of the measured queue length. Next, when the value of measured queue length is below a value set in advance with respect to the value of calculated queue length, the exchange decides the communication quality can be secured even if the call setting request is received and permits to connect a call. In such a way, since a rejection rate of a packet and an operation delay time are suppressed to some value or below, the communication quality can be secured.

Title: Flip-flop working at leading and trailing edges
Inventor: SATO YUICHI
IPC: H03K3/037
Filed: 1989-01-31
Abstract: PURPOSE:To attain the stable working of a flip-flop FF at both rise and fall edges by adding 1st and 2nd external inputs of the same frequency and four feedback inputs to a combination circuit to secure four stable states and actuating the FF. CONSTITUTION:An external input (x) and an external clock (t) are inputted to a combination circuit G 12 together with two feedback inputs (y) and (z) contained in the circuit. Thus the final output Y and the intermediate output Z are obtained. In such a case, the output Y is equal to the input (y) and the output Z is equal to the input (z) respectively. A 1st NAND secures a NAND product between both inputs (x) and (y), and a 2nd NAND secures a NAND products between both inputs (y) and (z) and the input (t). In the same way, a 9th NAND secures a NAND product between the input (y) and both inputs (y) and (z). A 10th NAND secures a NAND product among the output of the 1st - 5th NANDs, and a 11th NAND secures a NAND product among the outputs of the 6th - 9th NANDs. Thus four stable states are obtained and used to stably actuate a flip-flop FF at both leading and trailing edges.

Title: Internal flaw detection of billet by electronic scanning
Inventor: IWASAKI MASAYOSHI
IPC: G01N29/26
Filed: 1983-02-14
Abstract: PURPOSE:To improve the accuracy in detecting a micro defect and to improve the accuracy in estimating the position of the defect by setting a probe at a prescribed angle and at a prescribed distance from the surface of a steel material, scanning electronically said probe and detecting the internal flaw of the billet. CONSTITUTION:The echo S1 reflecting from the incident surface of an ultrasonic beam S remains substantially but the echo S2 reflecting from the side face of a square billet 1 advances downward and therefore the blind zone D by the echo S2 does not arise on the side face in the case of using an angle probe flaw detection method. The angle probe flaw detection method is thereupon used, and the side face adjacent to the incident face thereof is made a flaw detection region, by which the flaw detection from the surface to the inside of the billet 1 is made possible without the zone D. The accuracy in detecting the micro defect is thus improved and the accuracy in estimating the position of the defect is improved.

Title: Damping force adjusting type hydraulic shock absorber
Inventor: TANIGAWA FUJIO
IPC: B60G13/08
Filed: 1993-01-19
Abstract: PURPOSE:To selectively change damping force characteristic to three ways, hard, medium, soft, by providing main disc valves to control flow of oil liquid in main oil liquid passages so as to generate damping force, and subdisc valves to control flow of oil liquid in a bypass passage so as to generate damping force. CONSTITUTION:When main oil liquid passages are opened and a bypass passage 37 is closed by means of a damping force adjusting valve 45, large damping force is generated by the valve characteristic of main disc valves 27, 31. When the main oil liquid passages 25, 26 are closed and the bypass passage 37 is opened, smaller damping force than the damping force due to the main disc valve 31 is generated by the valve characteristic of a subdisc valve 42. When both the main oil liquid passages and the bypass passage 37 are opened, the damping force compounded out of both damping force due to the main disc valve 27 and the subdisc vale 42 is generated, and the smaller damping force than the damping force due to the subdisc valves 42, 43 is generated. In this way, by rotating the shutter 45, the damping force is changed to the three ways of valve characteristics.
