IPC: G02F1/1337
Filed: 1985-04-26
Abstract: PURPOSE:To improve display and driving characteristics by setting the ratio between the spiral pitch of the cholesteric phase of a smectic liquid crystal sealed between a pair of the substrates and the spacing between the substrates at >=0.5. CONSTITUTION:Transparent electrode patterns 22 which intersect orthogonally with each other are respectively formed on a pair of parallel glass substrates 21. The chiral smectic liquid crystal is sealed between the substrates. The phase of the liquid crystal is made isotropic by increasing the cell temp. and thereafter the cell is slowly cooled to transfer the phase to a Ch phase, SmA phase and SmC<x> phase.

Title: Fuel oil burner
Inventor: IZAKI HIROKAZU
IPC: F23D11/40
Filed: 1982-05-26
Abstract: PURPOSE:To permit a fuel oil and air to be excellently mixed thereby to obtain a blue-flame combustion, by providing an air supply pipe on the outer periphery of a fuel oil spray nozzle, and disposing an air flow settling plate at the outlet of the supply pipe so that the heat resulting from combustion is returned to the vicinity of the nozzle. CONSTITUTION:When the air for combustion passes through an air flow settling plate, the vortex flow thereof is suppressed, so that the turbulence thereof is reduced, and the direction, distribution and flow rate of the air are properly corrected. Moreover, the combustion air having passed through the plate 3 has its outer periphery inwardly throttled by a vane 11 upstanding on the inner wall of an air flow settling plate 5 and is provided with a vortex flow opposite in direction to the combustion air flow. Therefore, even when the vortex flow of the combustion air having passed through the air flow settling plate 3 has not well been suppressed, the vortex flows of the air at the inner and outer peripheral parts, which flows in opposite direction to each other, are attenuated by each other. In this case, a small vortex flow is produced in the boundary area, and this small vortex flow contributes to the mixing of a fuel oil and the combustion air.

Abstract: PURPOSE:To improve the processing efficiency for an electronic cash register system, by providing a console for operator, an adjustment device which is operated by a customer and a gate to shut off the unfair customers along a path for adjustment of the customer who purchased goods. CONSTITUTION:When a customer gets into a path, an operator feeds the data on the goods purchased by the customer through a keyboard 14. Then the input data is stored to an RAM13 of an electronic cash register ECR. With this data, a transaction data is transferred by the polling applied from an adjustment device 20. When the customer proceeds to the next device 20, an indication is displayed to the customer to use one of a cash transaction, a cash card and a credit card for adjustment. If the customer indicates the cash transaction and inserts the cash, a device 26c counts the amount of the inserted cash. When the counted amount is larger than the amount of adjustment, a change is discharged through a change discharging device 26d. In the case of a cash card, the secret number is collated with an inquiry to a bank, etc. If the customer is going to get out of the path, an alarm is produced to close the gate.

Title: Wire dot recording head
Inventor: KYOGOKU HIROSHI
IPC: B41J2/295
Filed: 1986-04-22
Abstract: PURPOSE:To shorten the period of time during which a vibration continues and contrive a higher recording speed, by driving a wire toward a recording medium by an electro- mechanical energy converting element such as a piezoelectric element, and attracting a leaf spring formed of a ferromagnetic material and connected to the wire by an electromagnet to restrict the wire to an initial position. CONSTITUTION:When a pulse P1 of a driving signal S1 is applied and a piezoelectric element 1 is expanded to strike a flight hammer 6, a wire 5 collides against a paper 9 against the force of a leaf spring 4, thereby recording a dot. After the collision, the wire 5 is returned by a repulsive force of a platen 10 and the force of the spring 4. An exciting signal S2 is applied to excite a magnetic coil 11 for a predetermined period of time from a moment immediately after the time A of the collision, and a magnetic flux passes through a mount member 3 and the leaf spring 4, resulting in that the spring 4 is attracted onto the member 3 by a magnetic force. Accordingly, the returning speed of the wire 5 is enhanced. When the wire 5 is returned to an initial position and the hammer 6 collides against the piezoelectric element 1, the leaf spring 4 also comes into contact with an end face 3b of the mount member 3, and is attracted onto the end face 3b.

That is, due to a proper selection from a thrust of the gas-spring 20 and a gradient of the crank 21, even when the cover 14 is stopped at any open position, the cover 14 can be balanced to stay at the position.
