Abstract: PURPOSE:To control an idle speed to be promptly focused to the target idle speed, by detecting a change of the idle speed per unit time while setting a control constant so that the proportion of said change is in a certain range and controlling an intake quantity of air by an actuator in accordance with said control constant. CONSTITUTION:A control unit 7, when it decides a throttle valve 2 to be placed in an idle opening by an opening signal 8, feeds a driving signal to an actuator 4 so as to obtain an idle speed set in accordance with the operation signal 10 which shows a change of operation in auxiliary equipments. In this way, the control unit, actuating a regulating valve 5 and adjusting an intake quantity of air, focuses the idle speed to a target idle speed. While here the control unit, calculating a change of the idle speed per unit time by an engine speed signal 9, sets a control constant so that a proportion of the change is in a fixed range. And on the basis of this control constant, the control unit, determining a driving speed of the actuator 4, controls the idle speed to be changed toward the target value within said fixed range.

IPC: B62D3/12
Filed: 1981-05-28
Abstract: PURPOSE:To reduce the weight of a rack shaft by forming a rack on the portion which is press molded from a steel pipe. CONSTITUTION:A rack shaft 2 is formed with a hollow rack shaft made of a thin steel pipe with a coaxial circular hole, and only the rack forming position is formed by press molding at a recessed section in parallel to the axis of the steel pipe and with a flat and rectangular bottom, then the rack 2C is formed on the bottom 2D of this recessed section.

Title: Delata modulator
Inventor: WADA SATOAKI
IPC: H03M3/02
Filed: 1987-04-01
Abstract: PURPOSE:To contrive the improvement of the performance of a digital modulator by inserting a constant current source between a capacitor of an integration circuit of a local decoder and its ground point so as to reduce distortion generated in the local decoder. CONSTITUTION:An analog input signal from a terminal 1 is added to a signal through a resistor from an output point (a) of a local decoder 3 through a resistor at a point (b) and inputted to a terminal D of a D.FF 8. The FF 8 compares the input signal with the analog input signal sampled by one preceding sampling period depending on its input potential and discriminates whether the potential is increased or decreased. Then the result of discrimination is given to a terminal 5 from a terminal Q and it is a digital converting code. On the other hand, a signal at a terminal Q being inverted logic level (1, 0) with the digital modulation code is inputted to the decoder 3. The decoder 3 integrates the 1, 0 signal by the charge/discharge to the capacitor 10 to increase/decrease linearly the output waveform of the decoder 3 by the action of a constant power supply employing a transistor 14.

IPC: B22D17/32
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To enhance a pressurization effect, to improve hermetic sealability and to obtain a produce free of internal defects by dividing the pressurization stroke of a pressurizing member to >=3 sections and determining the pressurization start time of the next section in accordance with the required time of the respective sections. SOLUTION: At the time of packing molten metal into a cavity, a high-speed changeover signal of a plunger is received and the pressurization of the first section is started after the respective waiting time. Accompanying this pressurization, the time required for the pressurization of the first section is measured. A difference between the result thereof and the preset time is calculated and the pressurization stage of the second section is started immediately when the actual measurement time is longer than the set time. Conversely, when the actual measurement time is shorter than the set time, the solidification is decided to be delayed as compared with a standard state and, therefore, the waiting time is calculated according to this time difference and the shifting to the pressurization stage of the second section is waited for this time. Similarly, the start time of the pressurization stage of the third section is derived from the time required for the pressurization of the second section and thereafter, the control is executed repetitively from the third section to the final n-th section.

Title: Image forming device
Inventor: TAKAHASHI MITSURU
IPC: G03G15/16
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To satisfactorily perform the transfer of a toner image between a belt-like photoreceptor and intermediate transfer body without scattering toner dusts. SOLUTION: A roller 13 around which the belt-like photoreceptor 2 is laid is brought into contact with the belt-like intermediate transfer body 3 between a ground roller 14 and a bias roller 15, and the part between the rollers 13 and 14 is specified as a nip part. In the gradation of potential from a ground part G to an application part Vi, the part where a current does not flow ends within the nip, therefore transfer charges applied to the belt-like intermediate transfer body 3 do not move upstream from the nip part in the direction of the movement of the belt-like intermediate transfer body 3 and an electric field which exerts an influence on transferred image quality does not occur.  Also, because the belt-like photoreceptor 2 goes into the nip part from the side of the ground roller 14 toward the side of the bias roller 15, an image on the belt-like photoreceptor 2 does not receive an electric field by the bias roller 15 when going into a nip entrance Nin, and transfer dust is, therefore, restricted.

Filed: 1981-05-29
Abstract: PURPOSE:To allow impressing homogeneous pressure on each electrode when bonding for good bump connection, by interposing a resin layer between a flip chip element substrate having bump electrodes and a holding substrate to adhere in a sandwich structure. CONSTITUTION:A resin layer 6 with high heat resistance is interposed between the flip chip element substrate 5 having bump electrodes and holding substrate 7 for thermo compression bonding in the process of forming bump electrodes to adhere the flip chip element substrate 5 and holding substrate 7 on the resin layer 6 to a sandwiching structure. Thus, since the resin layer 6 becomes elastic like a cushion when impressed by pressure, each electrode is evenly impressed in the presence of ununiformity in the height of each electrode or package bending. Then, the reliability of bump connection is improved with less unhomogeneity or reduction of bump connection.
