IPC: G02F1/017
Filed: 1986-07-03
Abstract: PURPOSE:To provide an optical switch having the smaller size, high efficiency and lower loss by providing an optical waveguide and electric field impressing means via an intermediate layer formed with multiple quantum wells in a layer thickness direction. CONSTITUTION:A buffer layer 22, an n-AlGaAs layer 23, i-GaAs/AlGaAs multiple quantum well structure intermediate layer 24, a p-AlGaAs layer 25 and a p-GaAs cap layer 26 are laminated on an n<+>-GaAs substrate 21. Clad layers 27, 29 and guide layer 28 consisting of i-AlGaAs are formed in the two grooves arriving at the layer 22. An electrode 9 in contact with the groove is formed on the slit of an SiO2 layer 30 and an electrode 10 is formed on the substrate 21. The layer 28 in the above-mentioned constitution forms a directional coupler via the mesa including the layer 24; therefore, the incident light on one waveguide moves periodically between the waveguides as the light progresses. An electric field is impressed to the layer 24 and the coupling of the coupler is released if a reverse bias is impressed between the electrodes 9 and 10; therefore, the optical switch action is obtd. if an element length is selected.

Abstract: PURPOSE:To form a stampable sheet having high mechanical strength by spinning out the melt of a resin composition composed of a thermoplastic resin and a liquid crystal polymer having a liquid-crystal transition temperature higher than the melting point of the resin from a nozzle plate, shaping a solid net body and compressing the solid net body. CONSTITUTION:It is preferable that a 20-95wt.% thermoplastic resin and a 5-80wt.% liquid crystal polymer are mixed. The melt of a resin composition is spun out of the nozzle plates 11... of an extruder 1, and the coninuous monofilaments 31... of the spun-out melt are dropped by their own weight, and deposited on the transfer surface of a transfer body 21. The transfer body 21 has a large number of protrusions 21a..., and is moved forward in the A direction while being vibrated in the direction orthogonal to the A direction. Consequently, the monofilaments 31... are bent in three dimensions, crossed at places and extended, and fused mutually at the positions of crossing, thus forming a solid net body 3 having a large number of crests and bottoms. The solid net body 3 is heated at a temperature higher than the melting point of the thermoplastic resin and lower than the liquid-crystal transition temperature of the liquid crystal polymer by a heating roll 5, and compressed, thus shaping a stampable sheet 4.

Abstract: PURPOSE:To prevent the formation of a concaved defect onto a discharge pipe by the top edge part of a vibrationproof coil by positioning the top edge part of the vibrationproof coil at the rectilinear part of the discharge pipe when bending work is carried-out by a machine in the state where the vibrationproof coil is inserted into the discharge pipe. CONSTITUTION:The discharge pipe 3 of a sealed type compressor is inserted into the outer periphery of a vibrationproof coil 6, meandered to provide elasticity. When mechanical bending work is carried-out automatically in the state where the vibrationproof coil 6 is inserted into the discharge pipe 3, it is feared that a concaved defect is formed by pressing by a jig 9 when the top edge part 6a of the vibrationproof coil 6 is positioned at the bent part. In order to prevent the formation of defects, bending work is carried-out by positioning the top edge part 6a of the vibrationproof coil 6 previously at the rectilinear part of the discharge pipe 3. Therefore, the application of a force in the longitudinal direction onto the discharge pipe 3 is prevented, and the formation of the concaved defect is prevented.

Abstract: PURPOSE:To eliminate abnormal ignition on the basis of circuit fault and the like, by a simple circuit constitution where an abnormal signal state of a circuit itself is detected, and fan out of a rotational synchronous input signal and the abnormal signal is identical with an ignition signal. CONSTITUTION:A circuit 1 is a circuit for operating an advanced angle alpha so as to operate ignition timing from an input pulse, and a circuit 2 is a circuit for receiving an output signal Vb of the circuit 1, and operating a closing angle delayed from an ignition position by a predetermined time tau. A rise point (i) and a fall point (ii) of a pulse Va inputted to a terminal (a) correspond to specific rotational positions of a crank shaft, respectively. A pulse Vb rises at an ignition position (iii) dependent upon the advanced angle alpha operated by the circuit 1, and falls at a position synchronous with the rise point (i) of the input pulse Va. A pulse Vc rises at a point (iv) where an ignition coil starts to be energized, which point is operated by the circuit 2 in response to an ignition coil energizing signal, and falls at the ignition position (iii). In the case that the circuit 1 fails to operate, an output Vd of an AND element 20 becomes identical with the input pulse Va, and an output Ve of a flip-flop 10 remains low level. Further, an ignition signal Vf of an output of an OR element 30 becomes identical with the input pulse Va, and an ignition position is automatically fixed to the position (ii).

Title: Heat-cooking utensil
Inventor: FUJII YASUTERU
IPC: F24C7/08
Filed: 1982-09-10
Abstract: PURPOSE:To significantly improve the durability of preset time sensor, by arranging such that the sensor is retained in a preset temperature range outside a reducing action improving temperature range for thereby minimizing the period of time that the sensor is exposed to the reducing action improving temperature while the sensor is being cleaned after a cooking operation. CONSTITUTION:Upon the passage of preset time after a cooking operation, a signal VH is outputted from a heating time control circuit for energizing the heater of sensor and then the cleaning operation of sensor is started. The first energization ceases upon the sensor being heated up to a temperature Tx preset rather above a reducing action improving temperature. When the sensor has its temperature cooled down through a natural heat dissipation again to the temperature TX, its energization is again started. The energization of heater after the second time is continued only for a preset period TR and is stopped upon the passage of preset period TR. The energization of heater after the third time repeats a cycle wherein the heater is energized for a preset time period upon the temperature of sensor lowering to the temperature TX. By controlling the sensor in the above manner, the temperature of sensor can be maintained substantially at constant in the range TX-TY.
