Patent JP-H02282961-A (JP)
Title: Tension servo device
Inventor: SAKAMOTO HITOSHI
IPC: G11B25/06
Filed: 1989-04-25
Abstract: PURPOSE:To make a tension detecting mechanism light weight and to improve the responsiveness of a detecting system by voltage-driving a reel motor, making a tape supporting post of ceramic, and setting the winding angle of the post at >=90 deg.. CONSTITUTION:A supply reel motor 72 is voltage-driven. Thereby, rotation is held with velocity viscosity due to the motor 72, and resistance against oscillation and rolling can be obtained. Also, a post 74 made of ceramic is used, and also, an arm made of aluminum is used, which makes a tape tension detecting mechanism light weight. In such a way, the responsiveness is improved, and also, since no counter weight is required at the other end 75B of the arm 75, no delay of response due to inertia or detecting error is generated. When a panel plane 80A is used facing upside, since the direction of the arm 75 is set almost in parallel with the direction G of gravity, no error due to the gravity is generated. The winding angle theta of the tape 3 on the post 74 is set at <=90 deg., for example, at >=150 deg., thereby, the compliance of the arm 75 can be increased.

Filed: 1987-04-27
Abstract: PURPOSE:To enable delicious tea or coffee to be always enjoyed by a method wherein it is checked if the amount of liquid contained in a container is deficient or not and generates an alarm, the liquid is positively boiled and the liquid is kept at a temperature higher than the desired value. CONSTITUTION:Under a condition in which an electrical vibration of for example 4 MHz is always applied from an oscillation circuit 41, if a water level within a container 4 is lower than a sensing part 13 for detecting an amount of water, an electrostatic capacity between a first electrode 15 and a second electrode 16 is decreased and a signal indicating a lack of amount of water is outputted from a switching circuit 42. When the amount of water in the container 4 is more than a desired amount, an LED 19 is illuminated unless a thermistor 7A detects a temperature higher than 97 deg.C and then a state that a boiling operation is being performed is indicated, and a heater 6 may perform a heating of 100% to cause a desired boiling operation to be carried out. If a desired amount of time (for example, 20 minutes) is passed after energization of the heater 6, LEDs 19 and 20 are illuminated together, an alarm 71 is informed and then the heater 6 is rapidly turned off. In turn, when a lower thermistor 7B detects a temperature lower than 85 deg.C, the heater 6 performs a heating of 5% (30 W) of a maximum output and performs a desired keeping of high temperature condition.

Title: Semiconductor device and producing method therefor
Inventor: OKA HIROTAKE
IPC: H01L21/60
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent aluminium wire disconnection caused by the generation of gas during a high temperature leaving test. SOLUTION: A power transistor 19 is produced by using a platingless copper lead frame and an aluminium wire, and both the ends of aluminium wire 16 are bonded to an electrode pad 12a of pellet 12 bonded to a header 10 and bonding parts 7a and 8a of inner leads 7 and 8. The 2nd bonding of aluminium wire 16 is executed to a wire bonded layer 15 formed by sticking silver foil to the bonding parts 7a and 8a of inner leads. Thus, since the aluminium wire 16 performs the 2nd bonding to the wire bonded layer 15 of silver foil, no Al-Cu layer is formed. Even when gas corroding the Al-Cu layer is generated from the resin of resin sealing body during the high temperature leaving test, since the 2nd bonding part does not corrode, the aluminium wire 16 is not disconnected.

Title: Driving method for dc type plasma display panel
Inventor: TERONAI YUUJI
IPC: G09G3/28
Filed: 1991-05-10
Abstract: PURPOSE:To obtain the driving method for the DC type plasma display panel which can reduce the total electric power of the power circuit of a driving system by applying an intermediate bias voltage between both reference potentials of an anode driving signal and a cathode driving signal. CONSTITUTION:An anode is applied with the anode driving signal including maintaining pulses of high frequency and write pulses based upon light emission and erasure data and a cathode, on the other hand, is applied with the cathode driving signal including sequential scanning pulses and erasure pulses matching the timing of erasure. At this time, width of the intermediate potential Vmv is provided between the OFF levels of individual anode-side and cathode-side pulses. Consequently, even when the anode driving signals and cathode driving signal have the same peak voltage values as before, a source voltage supplied to each driving circuit can be lowered, so the reduction of the total power consumption of the driving device can be expected and the reduction of the cost of a driver IC can be expected. Further, the voltage applied to the high- voltage power circuit of the driving system becomes low, so a noise and abnormal light emission at the time of the switching of a high voltage can be suppressed.

Title: Voltage controller of ac generator for vehicle
Inventor: SATO HIROHIDE
IPC: H02P9/14
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To increase the charging performance of a battery by holding the battery voltage as high level as possible within an allowable range from an overcharging preventive point of view. SOLUTION: When the average value of the battery voltage in a given period of time (3-30 minutes) including a given increase and decrease in the number of rotations of an engine exceeds a given level V1 (step 108), the adjustment voltage is lowered (step 138) to lower the battery voltage. On the other hand, when the average value of the battery voltage comes below the predetermined level V2 (step 112), the adjustment voltage is raised (step 116) to raise the battery voltage.  Since the adjustment voltage is switched, based on the average value of the battery voltage or the integrated detected value of the battery voltage, the average value of the battery voltage does not change so frequently along with a short-time fluctuation (increase and decrease) of the battery voltage caused by the change in the number of rotations of the engine as in the conventional method, thereby stably keeping the average value near a specified level.

IPC: F04C29/00
Filed: 1989-04-26
Abstract: PURPOSE:To prevent insufficient lubrication by allowing formation of a recess as oil sump in a position and size to provide three divisions by eccentric rotation of a rolling piston while a rotary shaft makes one turn at the inner surface of a bearing plate. CONSTITUTION:With one turn of a rotary shaft 4 a rolling piston 6 rolls on the inner wall surface of a cylinder 5, and when a recess 18 provided in a bearing plate 7a lies in a division situated inside of the piston 6, the lubricant oil inside the piston 6 is fed to this recess 18. In another division where the recess 18 is blocked with the end face of the piston 6, the lubricant staying in the recess 18 is held as it is. When the recess 18 is further put in communica tion with a low pressure chamber 10, the lubricant in the recess 18 flows out to this low pressure chamber 10 through the action of suction gas stream etc., and the recess 18 having got rid of the lubricant is again blocked with the piston 6. The position is restituted to the initial, and the recess 18 is in communi cation with the inside of the piston 6. Thus the lubricant in an amount propor tional to the capacity of the recess 18 per turn of the rotary shaft 4 is fed to the low pressure chamber 10 regardless of the pressure conditions.
