Title: Preparation of single-side plated steel plate
Inventor: FUJITA YOSHINORI
IPC: C23C2/02
Filed: 1979-03-05
Abstract: PURPOSE:To prevent completely one side of a steel plate from being plated by molten metal, by coating an aqueous slurry comprising magnesia, alkali silicate, alkali metal hydroxide, boric acid, titania or the like on the other side of the steel plate. CONSTITUTION:Five components comprising magnesia or magnesium hydroxide, alkali silicate such as water glass, alkali metal hydroxide such as NaOH, boric acid and one or more of titania, titanium hydroxide and titanic acid sol are dissolved or dispersed in an appropriate amount of water. This aqueous slurry is coated on one side of a steel plate and this coated steel plate is passed through a molten plating metal bath. Thereby, the plating of the other side is completely inhibited. Subsequently, when the plated steel plate is immersed in water and rapidly cooled, a coating film is completely released. Moreover, when brushing, blower drying or the like is applied, a single-side plated steel plate whose one side is uniformly plated and other side retains a beautiful cold-rolled surface is obtained.

Title: Control device for drive system of hydraulic pump
Inventor: TANAKA YASUO
IPC: F04B49/00
Filed: 1983-02-19
Abstract: PURPOSE:To easure stabilized control even under drift generation by calculating the pulses in the range, wherein the deviation of number of revolutions is constant, to the pulses in the period, wherein the rack amount includes the maximum value, and by making correction of the tilt angle of oil-hydraulic pump using the correction value obtained through said calculation. CONSTITUTION:No.1 counter 36 and No.2 counter 37 emit TDELTANM, TYM. A subtractor device 38 calculates TYM/TDELTANM, and emits the resultant value D of this ratio calculation. When this value D takes a smaller value D2 than the D1 which represents normal case without any drift, a function generator 39 emits a correction value dk2. This correction value dk2 is added to the pump control coefficient Kp to obtain a corrected pump control coefficient. As a result, influence of the drift is removed.

Title: Device testing apparatus
Inventor: OZAKI KAZUNARI
IPC: G01R31/26
Filed: 1989-02-03
Abstract: PURPOSE:To effectively prevent the generation of dew condensation by blowing dry hot air into a performance board mounting a device and allowing the same to flow out to the outside from the interior of said board. CONSTITUTION:When a device 1 to be tested is subjected to a low temp. test, the atmosphere of the device 1 is set to low temp. At this time, for example, the dry hot air of several ten  deg.C generated in a dry hot air generator 6 passes through a flow pipe 7 to flow in a performance board 2 and, therefore, the temp. of the performance board 2 itself becomes high. Further, since the dry hot air flows out from the holes 8-1, 8-2... provided to the performance board 2, the surface atmosphere of the board is dried and raised in its temp. Therefore, the amount of the saturated steam of the atmosphere on the surface of the board and in the vicinity thereof increases and dew condensation can be prevented.

Filed: 1984-02-15
Abstract: PURPOSE:To facilitate adjustment and maintenance inspection by constituting a single lens mirror optical element so that it has the functions of both a cylindrical lens, a reflecting mirror, and a dustproof member. CONSTITUTION:The lens mirror optical element 7 has three end surfaces, i.e. incidence surface 70, reflecting surface 71, and projection surface 73 for a light beam LB. The light beam LB is deflected by each deflecting surface according to the rotation of a rotary polygon mirror 1, and converged by a condenser lens 2 to form an image on a photosensitive body 6. For example, the incidence surface 70 is formed cylindrically and functions to correct scanning-directional and vertical deviation of the light beam from the axis of rotation of the rotary polygon scanning mirror 1 due to variance in parallelism among polarizing surfaces. The reflecting surface 71 is formed at a specific tilt angle to the incidence surface 70 and reflects the light beam LB which has the vertical deviation corrected when passing through the incidence surface 70 to guide the beam onto a specific scanning line on the photosensitive drum 6.
