Title: Measuring instrument with generating function
Inventor: YAMAGUCHI YASUYUKI
IPC: G01B21/22
Filed: 1986-06-19
Abstract: PURPOSE:To always secure sufficient electric power with no need of replacement work of battery and to measure with high accuracy by providing a linear type generator incorporating in a main body of a measuring instrument and providing a device which drives this generator. CONSTITUTION:A driving member 21 moves a rotor 31 with linear and relative displacement moving relating to a stator 35 by moving a spindle 8 vertically. Thus, the generating means 200 is driven by the driving means and single phase AC power is generated by a generator 30 through output lines, i.e., lead wires 38, 38 connected to a coil 37 of a stator 35. A rectifier circuit 40 rectifies the power with full wave rectification to charge DC power to a capacitor 51 formed by electric double layer in a battery circuit 50. Therefore, the measuring circuit is secured with a smooth operation by means of DC power from the battery circuit 50. In case the spindle 8 is moved with a speed higher than needed owing to inexperience, etc., of a measuring operator, overcharge is stopped by the act of an overcharge prevention circuit 60. High accurate measurement is thereby carried out, always securing sufficient electric power.

Title: Picture signal recording and reproducing device
Inventor: KINOSHITA TAKAO
IPC: H04N5/335
Filed: 1981-09-12
Abstract: PURPOSE:To eliminate the influence of the dark current, by dividing one picture element of a solid-state image pickup element into plural regions and providing a transfer register in every region and transferring the electric charge in every region independently and making the optical signal in every region binary to circulate it in the image pickup element. CONSTITUTION:Each of picture elements (11)-(44) of a solid-state image pickup element is divided into 4 regions A-D. Respective light receiving parts of picture elements constitute longitudinal shift registers 11a-11d,-44a-44d. Lateral shift registers 4 and 7 for output and a lateral shift register 8 for input are provided for respective picture element rows. The electric charge in every region is transferred independently and is outputted to the output register 4 or 7. The output of the register 7 for output is made binary and is transferred to the register 8 for input. At the time point when contents of the register 8 are transferred to the lowermost picture element line (41)-(44), the output of the register 4 is connected to the register 8 and is circulated in the image pickup element. Thus, the breakdown of the picture signal due to the dark current is prevented to store the signal for a long time.

Filed: 1988-06-10
Abstract: PURPOSE:To obtain a flexible heat-resistant non-combustible composite material by using an aqueous film forming inorg. compound having specific components alone or using the same as a compositional material in combination with various natural or synthetic mineral products. CONSTITUTION:Various natural or synthetic mineral powders, fibers or laminar compounds such as mineral powders, kaolin, pozzolan, silica fume, bauxite, pyrophyllite, metal oxides, metal hydroxides, cement or the like are mixed with an aqueous film forming inorg. compound represented by formula and the resulting mixture is used as a surface coating material or an adhesive material. In this case, even when this material is exposed to a high temp. burner, heat conduction is obstructed by the removal of the water of crystallization without damaging an inorg. film and, further, said material becomes a heat- resistant film to prevent the inflow of radiant heat. In addition, this material has fire-resistant bonding strength, generates no release and has a characteristic flexible in normal state in spite of an inorg. composition. Therefore, a fire- resistant/fireproof composite material of every kind can be prepared.

Title: Hydraulic damper
Inventor: SUNAMI KAZUO
IPC: B60G13/08
Filed: 1991-06-17
Abstract: PURPOSE:To give a temperature compensating function to a hydraulic damper for a vehicle suspension device by connecting a piston rod and a valve set shaft to each other by the use of a spacer made of a material having a linear expansion coefficient smaller than those of members constituting the damper. CONSTITUTION:A piston rod 13 is formed at one end thereof into a hollow shape. A valve set shaft 11, and a spacer 12 made of a material such as ceramics having a linear expansion coefficient smaller than those of other members constituting a hydraulic damper 1 are provided. The valve set shaft 11 is not directly connected to the piston 3 nor the piston rod 13 but connected to one end face of the spacer 12. The other end of the spacer 12 is connected to the piston rod 13. With this constitution, when the hydraulic damper 1 is expanded due to an increase in oil temperature, the spacer 12 is relatively contracted so that the valve set shaft 11 is relatively moved in the axial direction with respect to the piston 3. Consequently, an opening area of an orifice 10 is changed, thus compensating damping force.
