Title: Magnetic recording medium
Inventor: KONO KENJI
IPC: C09D5/23
Filed: 1988-03-02
Abstract: PURPOSE:To improve electromagnetic conversion characteristics by incorporating a polyurethane resin having a tertiary amino group or the salt thereof into a binder forming a magnetic layer. CONSTITUTION:The magnetic layer contg. magnetic powder and the binder is formed on a nonmagnetic base. The polyurethane resin having the tertiary amino group or the salt thereof is incorporated into the binder. The required mechanical strength is obtd. if the number average mol.wt. of the polyurethane resin is specified to 20,000-60,000. The prepn. of a magnetic coating compd. having an adequate viscosity is possible when said compd. is prepd. by using the above-mentioned resin. The degradation in the dispersibility is prevented by confirming the content of the tertiary amine or the salt thereof to <=2X10<-3>mol./g. The dispersibility is, therefore, improved if the polyurethane resin is used as the binder. The magnetic recording medium having the excellent electromagnetic conversion characteristics is thus obtd.

Abstract: PURPOSE: To use partitioned spaces effectively and independently, by providing an unloading partition board rotatably at the intermediate section in a load box for the purpose to partition the load box into front and back sections.  
     CONSTITUTION: When transporting unload different types of loads, the cylinder 13 is first contracted to engage the unloading partition board 17 1  with a stopper 21 to set the board 17 1  at the front end position and to suppress the rotation of said board 17 1  by the insertion of a stopper pin 20. Under this state different types of loads are loaded in front and rear sections f, r respectively and transported. Upon coming to an unloading position of the load in rear section r, the stopper pin 20 is drawn out, then the cylinder 13 is extended and said board 17 1  is moved backward along a guide rail 10 thus to unload the load in the rear section r. When unloading the load in the front section f, the cylinder 6 is extended to tilt the load box.

Title: Device for continuous performance of sludge freezing, melting and dehydration
Inventor: KOBAYASHI TOSHIYUKI
IPC: C02F11/20
Filed: 1978-04-25
Abstract: PURPOSE: To transfer the frozen sludge from the cooling drum to the warming drum by interposing a peeling roller instead of an inductive heater.  
     CONSTITUTION: The sludge supplied by a sludge supplier 3 onto a conveyor belt 4 is brought into a pressed contact with the outer peripheral surface of a cooling drum for freezing. When the sludge thus frozen reaches the vicinity of a peeling roller 15, it is separated easily from the outer peripheral surface of the cooling drum 14 due to a formation of the outer peripheral surface of the cooling durm 14 in a sphere and the difference of the expansion coefficient between the cooling drum 14 and the frozen sludge. Then the frozen sludge is transferred to an adjacent warming drum as it is attaching to the conveyor belt 4. Thus, the device can be simplified compared to the conventional one which requires an inductive heater, a heat receiving belt, a separating roller and the like.

Title: Thermally writing liquid crystal light valve
Inventor: KATO YUJI
IPC: G02F1/13
Filed: 1986-03-07
Abstract: PURPOSE:To form scattering nuclei over the whole layer of a liquid crystal by heating the liquid crystal layer from the direction of both substrates and to increase the display contrast by irradiating a liquid crystal light valve with laser light which is almost perpendicular to each axis of polarization being absorbed by a first and a second light absorbing film. CONSTITUTION:First laser light having axis of polarization coinciding with a major axis of dye molecules in the light absorbing film 11 and second laser light having an axis of polarization almost coinciding with the direction of the major axis of a dye molecule in the light absorbing film 7, have axis of polarization almost perpendicular to each other. The first and the second laser light (writing light source) are made incident on a liquid crystal light valve. the first laser light having the axis of polarization coinciding with the major axis of the dye molecule is absorbed almost completely in the light absorbing film 4, and almost all of the second laser light having the axis of polarization almost perpendicular to the axis of polarization of the first laser light transmits the light absorbing film 4 almost completely, but is absorbed y the light absorbing film 8 almost completely. By this mechanism, both light absorbing films 4 and 8 generate heat, thus the liquid crystal 14 is heated from the laser light side and the light projecting side, forming scattering nuclei in the almost whole liquid crystal layer. Thus, high contrast 10 is obtd. by each 15mW laser, namely 30mW in total power consumption.

Title: Ion source unit
Inventor: SASAKI SHIGEO
IPC: H01J37/08
Filed: 1986-03-05
Abstract: PURPOSE:To make it possible to generate ion beams stable for a long period of time, by furnishing an insulator to cover partially or all the inside of the container of an emitter, and a power source to heat the emitter by applying a current between the emitter and the container. CONSTITUTION:A current is applied as shown in the figure by using a heating power source 8. As a result, the current flows through a current terminal 7, a lead wire 13, and an emitter 4 covered by an insulator 17, and led to a reservoir 1 through gallium 3. And then, it flows through a lead wire 14 and the terminal 7, and returns to the heating power source 8. In this current flow passage, the part of the emitter 4 covered by the insulator 10 is mostly heated by the current. This heat heats the gallium 3 and the whole reservoir 1 up to a high temperature by a heat radiation and a heat conduction. Therefore, the viscosity of the gallium around the needle form part of the emitter 4 is reduced, and the gallium 3 is fed to the tip of the needle part stably and for a long period of time. As a result, stable ion beams can be generated for long.

Title: Display device
Inventor: KAWACHI AKIHIKO
IPC: G02F1/1335
Filed: 1988-03-03
Abstract: PURPOSE:To obtain high-contrast black-and-white display at a low cost by placing a cellulose acetate butyrate sheet or film formed by a flow extending method on the front or rear side of a liq. crystal cell or on both sides. CONSTITUTION:Incident light 1 becomes linearly polarized light by passing through a polarizing plate as a polarizer 2 and passes through a display panel 3 (liq. crystal cell). When no voltage is impressed on the panel 3, the light passing through the panel 3 becomes circularly polarized light and returns to the linearly polarized light by passing through a cellulose acetate butyrate film 4 or sheet as a phase plate for optical compensation. Finally the light reaches a polarizing plate as an analyzer 5 but does not pass through the analyzer 5 because the axis of polarization of the analyzer 5 meets at right angles to that of the polarizer 2, a completely black display is obtd. When voltage is impressed on the panel 3, the incident light passes through the polarizer 2, the panel 3 and the film 4, so completely white display is obtd.

CONSTITUTION:The current from the oscillation means MC1 for a sensor of a control means MC is subjected to DC conversion to start a humidity sensor DS and the humidity in a storing chamber is always detected by the sensor DS and the output signal of the sensor is subjected to AC conversion by a humidity signal AC converter circuit CP2 and increased in its capacity by an energizing circuit CR3 to be transmitted to the A/D conversion input means MC2 of the control means MC. When it is transmitted that the humidity in the storing chamber is higher than a set value, a relay driving circuit CR5 is turned ON by the control means MC and a drying unit is opened by a timer circuit CR6 and, at the same time, a convection heater 50 is energized to heat the air in a lower chamber to form a rising air stream. As a result, when the humidity in the storing chamber lowers, the relay driving circuit CR5, the timer circuit CR6 and the convection heater 50 are interrupted.
