Title: Back-up plate apparatus for printed board
Inventor: WACHI AKIHIKO
IPC: H05K13/04
Filed: 1993-06-15
Abstract: PURPOSE:To provide a back-up plate apparatus in which a length of a support pin may not be altered even if a thickness of a printed board is varied and a back-up plate can be vertically moved at a short stroke without failure. CONSTITUTION:A back-up plate 10 is raised to a position corresponding to raising position data P1 with a value obtained by subtracting a board thickness(t) from a maximum stroke P0 as the data P1 on the basis of board data, and a board 3 is supported. At the time of conveying the board, a value obtained by adding a predetermined allowance size alpha to a maximum value (h) of a mounting height of an electronic component 7 mounted at a lower surface side of the board 3 is used as lowering amount data, a value obtained by subtracting the lowering amount data from the data P1 is calculated as lowering position data P2, it is lowered to a position corresponding to the data P2, and an elevating time is shortened with the lowering amount as a necessary minimum limit.

Title: Heating cooker
Inventor: KODAMA SATOSHI
IPC: F24C7/06
Filed: 1986-06-19
Abstract: PURPOSE:To make a heating chamber easy to use and improve its reliability with good heating performance by forming a heater in a plane shape and arranging it to cover substantially all the outside of the ceiling face of a heating chamber and constituting the ceiling face of the heating chamber with metal plates with a low thermal expansion coefficient and giving, further, a protruding section on the outside of the heating chamber. CONSTITUTION:Even if the plane heater 8 and mounting plate 9 of a heating chamber give thermal expansion as the heating progresses, the state of close contact between the plane heater 8 and the ceil-face of the heating chamber 1 does not change because the central section is pressed and fixed with an engagement metal fixture 12. Because a stepped screw 11 is tightened to a long hole, the mounting plate 9 extends in the direction along the plane. If the ceiling face 1a of the heating chamber 1 is constituted with metal plates with a low thermal expansion coefficient (for example, SUS 430, etc.) the amount of deformation can be kept low and it bends stably to the direction of the protrusion, strengthening the close contact between the plane heater 8 and the ceiling face 1a of the heating chamber, so that a heat distribution with an excellent heat efficiency and stability can be obtained.

Filed: 1991-06-14
Abstract: PURPOSE:To control the surface temperature of an image carrier to be constant at all times and to prevent the occurrence of a defective picture by holding the temperature set value of the image carrier at only moving time of an image carrier. CONSTITUTION:A thermistor 28 is provided on the end part of the surface of a photosensitive drum 1, where images are not formed. The surface temperature TD of the photosensitive drum 1 which is always detected by the thermistor 28 is inputted to a comparator circuit 32 as a voltage value. The set temperature TS at the time of the rotation of the photosensitive drum set by a temperature setting circuit 33 is also inputted to the comparator circuit 32 as a voltage value. The comparator circuit 32 compares them and outputs the result of the comparison (for example, in the cases of TD<TS and TD>=TS, '0' and '1', respectively) to a heater control circuit 31. The control circuit 31 controls the on/off of a heater 29 according to the inputted result of the comparison (for example, in the cases of '0' and '1', the heater is on and the heater is off, respectively).

Vermiculite is metallic oxides such as SiO2 and MgO and is effective for increasing its friction coefficient. Moreover, it has a layered structure, and therefore, its attackability for the mating material is low. Graphite has lubricity approximately to 400 deg.C as a self-lubricating component and furthermore has high effect on the wear resistance thereof. Thus, this material is used for the material for an automotive brake, the material for a clutch, or the like.

Abstract: PURPOSE:To prevent a screen from generating white or black horizontal stripes even if a pulse noise is mixed into a clamping position by providing the clamping circuit with a negative feedback action and a fly wheel effect and clamping a previously determined prescribed level in an input signal at a reference level. CONSTITUTION:When a clamp pulse (b) switches a switching circuit 2 to the side of a video output signal (e), a negative feedback circuit is constituted of a subtractor 1, the circuit 2, an amplifier circuit 4, and a loop filter circuit and negative feedback operation is executed so that a difference between the pedestal level of the signal (e) and the reference level becomes zero. When the circuit 2 is switched to the side of a reference level feeding source 3 by the pulse (b), the circuit 5 holds the potential of the negative feedback operation until the circuit 2 is switched to the signal (e) side. Since the time constant of the circuit 5 can be set up to a value larger than the repeating period of a horizontally synchronizing signal, the stable operation of the circuit 5 can be attained by providing the circuit 5 with a fly wheel effect.

Title: Heat exchanger tube
Inventor: MOCHIDA YOSHIO
IPC: F28F1/40
Filed: 1981-09-16
Abstract: PURPOSE:To increase the coefficient of heat passage of the titled heat exchanger tube and to  reduce a pressure loss by a method wherein a number of channels extending axially and a plurality of annular flat sections arranged crosswise at predetermined intervals are formed on the  inner surface of the heat exchanger tube and a plurality of helical flat sections turning in different directions are provided between each of the annular flat sections alternately. CONSTITUTION:The channels 11 extending axially and the annular flat sections 12 arranged at  intervals less than twenty times the inner diameter of the heat exchanger tube 10 are formed  on the inner surface of the pipe 10 which is used for a condenser in a power plant and the  helical flat sections 13 and 14 are formed among the annular flat sections 12 in such a manner  that the turning direction of the section 13 is made different from that of the section 14. With  the above structure, a boundary layer formed on the inner surface of the heat exchanger tube  is urged to exfoliate from the inner wall surface of the pipe 10. In this case, the exfoliated  boundary layer develops again on the surface along the flow direction of cooling water in the  pipe 10 but it comes off again from the surface due to the existence of the discontinuous convex and concave sections formed by the flat sections at intervals less than twenty times the  inner diameter of the tube 10. Further, the flow of the cooling water near the inner wall surface of the pipe 10 becomes turbulent by being interfered with a stream of a part of the water  flowing through the channels 11 and a swirling stream of a part of the water generated due to  the flat sections 13 and 14 so that the development of the boundary layer is controlled.
