Title: Light beam diameter changing device
Inventor: SATO MASUMI
IPC: B41J2/44
Filed: 1989-12-20
Abstract: PURPOSE:To change the size of a dot in one dot unit by impressing voltage on both end faces of an electrooptical crystal and varying a light beam diameter in one optical direction. CONSTITUTION:A linearly polarized light beam L is made incident on the electrooptical crystal 3 through a beam compressor 1. Then, it is refracted according to the refractive index of the crystal 3 on an incident surface and is not refracted on an outgoing surface because an outgoing angle is made 90 deg. with the surface of the crystal. By impressing the voltage on the crystal 3, the angle of refraction is changed and the light beam diameter is changed according to the impressed voltage. At such a time, the compressor 1 and a beam expander 2 are arranged so that their focal points may coincide with the center axis of the crystal 3. Thus, the size of the dot is economically varied in one optional direction in one dot unit by a simple means.

Title: Four-wheel steering device
Inventor: ARAI JUNICHI
IPC: B62D7/14
Filed: 1987-12-25
Abstract: PURPOSE:To enhance the maneuvering stability and small radius turning performance by connecting a first order delay circuit to one of a plurality of control cylinders, controlling this first order delay circuit according to the car speed by a solenoid, and thereby changing over the opposite and same phases in steering and also the duration of each phase. CONSTITUTION:When the front wheels are steered for ex. to the right, pressure fluid flows into pressure chambers 44, 63 of control cylinders S1, S2 upon passing through a passage 48. At this time, the pressure rise in the pressure chamber 44 is delayed by a first order delay circuit consisting of an orifice 50 and an accumulator 56. Accordingly pressure rises earlier in the pressure chamber 63 to put a piston 43 into motion, so that a soop 40 of a control valve V is changed over to the left position II. Consequently the pressure fluid flows into a pressure chamber 16 of a power cylinder C2 for rear wheels to steer them left. At the time of low speed running, for ex., the energization current for a solenoid 58 is increased to shrink the opening area of the orifice 50, and thus opposite phase of the front and rear wheels is maintained for a long period of time.

Title: Power generator
Inventor: KAWAI TERUO
IPC: H02K41/06
Filed: 1988-12-28
Abstract: PURPOSE:To obtain high power by forcing an attracted circular ion plate to set up a circular motion to cause the current to flow to electromagnets disposed circularly in an array one after another, and by setting up a rotating motion to a special-shaped non-ferrous power shaft provided through the center section of the iron sheet. CONSTITUTION:When electromagnets 1a, 1b and 1c are electrified by a current switching circuit 9, a part of the outside circumference of a circular iron sheet 4 is attracted to the electromagnet 1b. Then, when the current is switched to an adjacent electromagnet 1d (at this time the current to the electromagnet 1a is cut off.) a part of the outside circumference of the iron plate 4 is going to be attracted to the electromagnet 1c. While the iron plate 4 is attracted to each electromagnet 1 one after another, it performs a circular motion inside a train of electromagnets. It forces a special-shaped non-ferrous power shaft 5 to set up a rotating motion which is provided in the center section of the iron plate 4 so as to rotate independently of the iron plate 4. This rotating motion is utilized as a power source accordingly.

Title: Non-contact ic card
Inventor: MIYOSHI MOTOYUKI
IPC: B42D15/10
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To prevent alternating and remodeling by laminating the surface of the central layer storing electronic parts and forming the surface layer with a surface layer material causing in-layer peeling owing to a stress equal to below a breaking strength at the time of peeling of the surface layer. SOLUTION: This card has a structure in which the surface layer is laminated on one side or both sides of the central layer storing the electronic parts. As a material of the surface layer, it is not particularly limited provided that it has a stress equal to below the breaking strength of the surface layer itself and causes the in-layer peeling when the surface layer is peeled from the central layer, but a material in which holes or minute voids are formed on the surface and the inside of a plastic film (e.g. synthetic paper) is used from various characteristics required in the card, such as durability, printability, strength, processability, adhesive property, heat resistance at the time of laminating, cost, etc.  Thus, by using the resin material of which the surface layer breaks down within the layer in layers, the remodeling is prevented, and by using the resin material not including a halogen element, the generation of a halogenated hydrogen is avoided in incineration.
