Title: Actuator element to be led without friction
Inventor: PISCHINGER FRANK
IPC: F01L9/20
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To provide the high frequency motion, the minute stroke and force without frictional loss by fixing a reciprocal transmission member to a supporting body through at least two horizontally oscillating arm elements arranged with interval therebetween. SOLUTION: An actuator element comprises, for example, a transmission member 1 in the mode of a connecting rod, and the transmission member 1 is fixed to a supporting body 4 through horizontally oscillating arms 2, 3. The transmission member 1 is reciprocated by applying the force F to one end 5 in the longitudinally axial direction, and the other end 7 works on a final control element 8, for example, a valve. Thus, in the structural mode under the application of the force F, the transmission member 1 can be reciprocated in the longitudinal axial direction. Because the transmission member 1 is moved on the circular orbit in the maximum stroke, an appropriate horizontal motion can be obtained in the longitudinally axial direction. When the stroke is small, the circular motion becomes extremely small, the system works not only without friction but also without substantial loss.

IPC: G03G15/05
Filed: 1979-02-27
Abstract: PURPOSE: To achieve the stabilization of potential controlling by grounding the grid of an AC or DC corona discharging means by way of a resistance.  
     CONSTITUTION: The grid 22 of an Ac or DC corona discharger 3 is grounded by way of a resistance 24. As a result of this, light image exposure is done by an exposure light source 19 through the AC or DC corona discharger 3 on the photoreceptor 1 charged by a primary charger 2, after which the electrostatic latent images formed through full surface exposure by a lamp 4 are developed under the action of a developing electrode 5 and are further transferred onto transfer paper 8 and are fixed by a fixing device 9, at which time the current ratio of the AC or DC corona discharger 3 is made constant to obviate the decrease in discharging and charging efficiency, hence the potential controlling for converging the bright part potentials or dark part potentials on the photoreceptor 1 to the target values is stabilized.

Title: Copying device compensating for fatigue of photosensitive body
Inventor: IWAHASHI HARUO
IPC: G03G15/00
Filed: 1987-02-04
Abstract: PURPOSE:To compensate the fatigue of a photosensitive body and to obtain a copy image with proper density by controlling the charging current of a band electrode and/or the voltage of an exposure lamp in accordance with the degree of fatigue of the photosensitive body. CONSTITUTION:The fatigue of the photosensitive body appears as a phenomenon changing the charging potential of the body. In case of the photosensitive drum forming a latent image, the relation between exposure E and the charging potential Vs shows the characteristics shown by a broken line and a dynamic range is dropped when fatigue is generated. When the whole changing value of the drum is increased by a charging electrode and the exposure amount based on the exposing lamp is reduced, the charging potential Vs on a part with small exposure amount is increased and that on a part with much exposure amount is increased. Thereby, the whole dynamic range is expanded and the characteristics of copying density to the charging potential Vs can be improved from white up to solid black.

Title: Method of indicating corrected value in wheel balancer
Inventor: HIHARA YUKIYOSHI
IPC: G01M1/08
Filed: 1987-02-04
Abstract: PURPOSE:To improve single-sided correction in correcting unbalance only in either one of the inner or outer surface, by indicating on an indicating device an amount to be corrected, a position for correction, and whichever side-surface, whose couple, which occurs after the balance correction and which tends to incline the wheel, is smaller. CONSTITUTION:When a one-side selecting button 41 and a start button 38 are pushed in turn, an amount and a position for correction, which correspond to the unbalance consisting of the unbalance on both inner and outer sides of the wheel, are obtained, and at the same time the absolute values of both unbalance on the inner side and that on the outer side are examined. Based on these results, it is determined to which side (of the inner or outer side) a balance weight should be installed, from the viewpoint of lessening a couple, which occurs after the balance correction and which tends to incline the wheel. After this, both amount and place for correction are indicated only on the amount-indicator 42 or 43 and position-indicator 44 or 46, both of which correspond to the side thus determined. By installing a balance weight based on the above-mentioned indication, a couple, which occurs when the wheel rotates, can be made smaller.

Abstract: PURPOSE:To surely bond a heat sink to a housing part by a method wherein the heat sink is formed to be a square pillar shape, the cross-sectional shape of the housing part is formed to be a shape which is nearly identical to the cross-sectional shape of the heat sink and protrusion-shaped stepped parts are formed in corner parts on the bottom part of the housing part. CONSTITUTION:Protrusion-shaped stepped parts are formed respectively in four corner parts formed at a housing part 6 in a heat sink 7. The individual stepped parts 12 are formed in such a way that their plane shapes are nearly triangular shapes which are very small as compared with the area of a bonding face 6a. In a state that the heat sink 7 has been housed in the housing part 6, an adhesive 8 on the stepped parts 12 formed at the corner parts swells and is compression-bonded to hangings 7b at the corner parts of the heat sink 7. Thereby, since the adhesive 8 is bonded surely to the corner parts of the heat sink 7 in which the large hangings 7b exist, the bonding strength of the heat sink 7 can be enhanced.

Title: Oscilloscope
Inventor: NARUKAWA YASUNORI
IPC: G01R13/22
Filed: 1982-02-15
Abstract: PURPOSE:To conserve the power consumption of the power source by varying the resistance value of a variable resistance circuit inserted into a power source circuit of a power amplifier according to the selection of a swith for limiting band. CONSTITUTION:When a switch SW2 is turned to the position for bypassing a low pass filter LPF, a resistor R4 is selected and when it is turned to the position of the low pass filter LPF, a resistor 5 is selected while the resistance value of the resistor R4 is set at a value lower than that of the resistor 5. With such an arrangement, when the band is not limited, the power is amplified in a better linearity to a high pass frequency where deflection electrodes P1 and P2 give a low impedance. When the limiting of the band is performed, current energizing a transistor Q1 decreases to save the power consumption of the power source. This can achieve the conservation of the power consumption of the power source.
