Abstract: PURPOSE:To judge the steepness of a road and to suppress the generation of an intervehicle distance alarm by stopping the generation of the alarm for a certain period of time or during the period of a certain traveling distance when the average value of the product of a handle angle and lateral acceleration exceeds a prescribed threshold value. CONSTITUTION:A control unit 14 calculates a curving degree and the curving degree is the quantified value of the steepness of the road, in other words, of the busyness of a handle operation and also, the average of the product of the handle angle and the lateral acceleration in a certain period of time. Then, the value of the curved angle is compared with a prescribed threshold value 5 every second for instance, and the sounding of the alarm by an alarm generator 24 is stopped for 15 seconds thereafter in the case when the value is equal to or more than the prescribed threshold value 5. Also, in the case when the value of the curved angle is less than the prescribed threshold value 5, the alarm is sounded if conditions for sounding the alarm are satisfied. That is, in the case when the road is steep to the extent that the curved angle exceeds the prescribed threshold value 5, it is considered that the handle operation is busy and dozing off or the like can not occur, and the sounding of the alarm is stopped.

The degaussing of the false data recorded on the low-coercive force layer and the reading out of only the true data recorded on the high-coercive force layer are made possible by impressing the bias current within the range B on a magnetic head.

Title: Parameter value operating apparatus
Inventor: IIDA KOJI
IPC: H01C10/14
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To mechanically simulate a feeling for click by controlling a driving force control means so that a movable operation portion imparts a click against the moving operation when the movable operation portion is operated by manual to arrive at a portion within a given range. SOLUTION: The range of torque generation (torque drive range) and the direction of torque generation in the torque drive range (torque along positive direction/torque along negative direction) are set beforehand according to the positions of a fader. When the fader is located within the torque drive range, a torque is generated in a motor in a direction depending on the fader position. When the fader is located outside the torque drive range, no torque is generated. If, for example, the fader is positioned just within a range after or before the value 50 (i.e., in a range of around 47-53 in a flat portion), no generation of torque occurs. If positioned in the vicinity of range of around 53-60, a torque along negative direction is exerted, and if positioned in the vicinity of range of around 40-46, torque along positive direction is exerted on the motor.

Filed: 1984-11-30
Abstract: PURPOSE:To perform erasure effectively by providing an erasure control means which allows an erasing means to perform erasing operation from the driving start of a recording medium driving means until the driving means enters a specific driving state. CONSTITUTION:When a recording mode setting signal R goes up to a high level, a controller 12 places a switch SW1 at a side a1 and a switch SW2 at a side b2. A motor 2 is driven in this state and then the motor 2 attains to a target speed VP by braking operation at time t0. The value of an error signal outputted by an adder 8 in this period is not within a permissible error range and a high-level signal is outputted from an error signal detecting circuit 9 as shown by (c) in a chart; when the rotating speed of the motor 2 attains a preset speed at time (tes), a speed detecting circuit 18 outputs a high-level signal and an erasure control circuit 19 outputs a high-level erasure mode signal E as shown by (d), so that an erasure signal generator 10 generates an erasure signal (b) in the chart. At this time, the controller 12 operates the switch SW2 from a contact b2 to a contact a2 in response to the high level of the erasure mode signal E to turn on a recording amplifier 15 with a recording gate signal G as shown by (h).

Title: Manufacture of anode plate of alkaline storage battery
Inventor: SHIMODA MASAKAZU
IPC: H01M4/26
Filed: 1983-12-26
Abstract: PURPOSE:To decrease coming off of active material from the periphery of a plate and drop of discharge efficiency by pressing the periphery of a belt-shaped plate so as to have a specified porosity. CONSTITUTION:The periphery of a belt-shaped plate is pressed so as to have a porosity of 20% or less. In a paste type plate, A plate should be pressed so as to have a porosity of 20% or less in order to prevent coming off of active material. When the plate is pressed to such porosity, metal cadmium formed by reduction becomes dense and discharge utility of metal cadmium is decreased because of poor diffusion of electrolyte during discharge. Pressing whole surface of the plate so as to have a porosity of 20% or less is not preferable. Since most of coming off of active material occurs in the periphery of the plate, pressing only the periphery of the plate is satisfactory to prevent coming off of the active material.

Abstract: PURPOSE:To simplify a drive circuit, by a method wherein the control circuit is installed at input side of a high-voltage generating circuit, and a high-voltage capacitor to be installed to an output smoothing circuit of the high-voltage generating circuit is substituted by capacitance of a piezo-electric body. CONSTITUTION:A step-up DC-DC converter 1 is provided at input side with a control input terminal 4, and output voltage is outputted corresponding to the control input. In this case, a smoothing high-voltage capacitor is necessary at the output terminal, however, since the capacitance is supplemented by a piezo-electric element 2 to be driven, the capacitor becomes unnecessary. Thereby the output voltage is always smoothed, and the element 2 is controlled by control signal flowing in the control input terminal 4.
