Title: Semiconductor luminous element
Inventor: SATO MICHIO
IPC: H01S5/00
Filed: 1988-01-29
Abstract: PURPOSE:To bound excitons two-dimensionally and improve luminous efficiency by burying single-atom layers of family atoms in a compound semiconductor. CONSTITUTION:One In single-atom layer 5 is buried in a GaAs luminous layer to constitute a PN junction diode. When the electron affinity of family elements forming a single-atom layer 5 is weaker than that in the surrounding, positive holes are attracted since electrons are not liable to be present in an atom layer. Since a positively charged atom layer captures electrons by the Coulomb attraction, excitons bound two-dimensionally are formed. Luminous intensity is strong when bound excitons become extinct, and highly luminous efficiency can be obtained.

Title: Thermal switch
Inventor: KUDO AKIHIDE
IPC: H01H37/32
Filed: 1989-01-26
Abstract: PURPOSE:To obtain an inexpensive thermal switch having a simple construction by using a thermal reaction member, to which forced deformation is applied a ta temperature below a given transition point, as a contact switching means. CONSTITUTION:A thermal reaction member 10 is used which is formed with a high polymer material producing heat shrinkage or heat deformation, etc., at the time of abnormal heating instead of bimetal. Generally in the case where a high polymer material is forcedly deformed at a temperature below a glass transition point Tg to allow it to have residual stress, it tends to return to an original shape when it is heated up to Tg. A movable contact 13, fixed to the tip of a movable contact plate 11 of which base end is fixed, is brought into contact with a fixed contact plate 12, and the member 10 such as an acrylic plate is arranged at the lower part of the plate 11. Consequently when a thermal switch is heated, the thickness of the member 10 becomes thick, causing deformation of the plate 11 to open the thermal switch.

IPC: B22D27/04
Filed: 1980-02-18
Abstract: PURPOSE: To shorten a casting cycle by performing the directional solidification for pouring molten metal and by forcibly cooling a riser right after the temperature of the molten metal in a cavity reaches the range of a solidification completed temperature.  
     CONSTITUTION: While solenoid valve 8 is kept closed under the initial control of controller 10, prescribed molten metal is poured from sprue 2 to fill cavity 5 and riser 6 as well. On the stop of the molten metal pouring, the timer of controller 10 is started. As the time passes, the temperature of the molten metal falls from the lower part of cavity 5 through directional solidification and the molten metal starts solidification at solidification start temperature T 1 . Then, t 1  time later, the uppermost part B' of cavity 5 also reaches the range T 3  of a solidification completed temperature, so that the inside of cavity 5 is in a solidification end state. At this point of time, air from compressed air source 7 is blown to riser 6 via flowing tube 9 with solenoid valve 8 opened by controller 10 previously set for forcible cooling, thereby quickening the release of the mold by shortening the time of cooling for riser.

Title: Servo motor controller provided with anti-drift rotation function
Inventor: SAKIYAMA TAKASHI
IPC: H02P6/24
Filed: 1991-02-12
Abstract: PURPOSE:To prevent drift rotation by interrupting a speed feedback loop during halt of motor and controlling power conversion so that the field produced by an armature winding is fixed. CONSTITUTION:A PWM three-phase inverter comprises a current amplifier 4 for producing a variable frequency AC power supply from a DC power supply and feeding AC power to an AC synchronous servo motor 5. When a motor 5 is controlled through a speed regulator 1 and based on an external speed command Vs so that the actual speed Vi thereof matches with the speed command, a switch 10 is turned from side A to side B based on a latch signal 71a upon lowering of the rotational speed of the motor 5 below a predetermined level and a pole signal 6a is latched by means of the latch circuit 9. Consequently, a speed control loop is opened and a current command circuit 8a provides a command to a current control minor loop through the switch 10 so that a fixed phase current is fed to the motor thus fixing the rotor position and bringing the speed to zero. According to the invention, rotation due to drift of IC in the control circuit can be prevented.

Title: Liquid crystal display element
Inventor: KATO NAOKI
IPC: G02F1/1337
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display element scarcely having orientation defect and having a visual angle characteristic symmetrical with vertical and lateral directions and a high display grade excellent in the visual angle characteristic by providing the element with a nucleus generating part for transition from spray TN orientation to ordinary TN orientation. SOLUTION: Pixel electrodes 6 consisting of indium tin oxide(ITO) and thin- film transistors(TFTs) for driving the same are formed on a lower substrate 5. Saw tooth-shaped silicon nitride films SiNx 7 are partially formed on the pixel electrodes 6 consisting of the ITO. If 5V voltage is impressed between the upper and lower substrates, the spray TN orientation region existing in the beginning transfers to the ordinary TN orientation. Particularly, the ordinary TN orientation is effectively transferred from the regions of the silicon nitride films SiNx 7 formed to the saw tooth shape formed on the pixel electrodes 6 consisting of the ITO. This transition spreads over the entire part of the pixels. As a result, the good characteristic which is vertically and laterally symmetrical and is extremely wide in the visual angle is obtd.  Further, the unequal display is not observed when viewed from any visual angle direction and the extremely high display grade is obtd.
