Title: Optical modulator for which superlattice layer is used
Inventor: SAKAKI HIROYUKI
IPC: G02F1/19
Filed: 1985-03-13
Abstract: PURPOSE:To make the efficient change of refractive indices possible by the lower driving voltage by adopting layer structure in which superlattice layers are used and impressing the voltage to the superlattice layers. CONSTITUTION:This optical modulator is constituted by laminating repeatedly the 1st layers 1-1, 1-n and the 2nd layers 2-1, 1-n having the different refractive indices and using the superlattice layers consisting of extra-thin films (a), (b) consisting of different compsns. for the 2nd layers 2-1, 1-n. The repetitive period T thereof is made half the wavelength and the refractive indices are changed by applying the electric field to the superlattice layers. Light reflects at the boundary faces of the respective layers having the different refractive indices when the light is made incident through an upper transparent electrode 3 on the optical modulator of such multi-layered film type. The reflected light is intensified in the phase under certain condition and is weakened in the phase under the other condition.

Title: Sweep system
Inventor: YAMANE HIDEO
IPC: G01S13/66
Filed: 1981-04-03
Abstract: PURPOSE:To shorten the locking time without deteriorating the lock sensitivity of a frequency following loop by imparting the function of changing over the sweep velocity to the frequency following loop. CONSTITUTION:When signal in the Doppler range is applied to the mixer 1, the sweep circuit 7 applies first sweep signal of high speed to a voltage control oscillator 10 through a summing amplifier 8 and so on. Next, the output signal of the mixer 1 changes its frequency in response to the sweep signal. When this frequency exceeds the set value of a lock judgement circuit 5, it is stored in the memory circuit 6, and next, the content in the memory circuit 6 is applied to the sweep circuit 7 during sweeping and the sweeping speed becomes slow by the portion of the frequency that is stored in the memory circuit 6. With imparting the function to change-over sweep speed to the frequency following loop, the locking time can be shortened without deterioration lock sensitivity.

Title: Manufacture of polycrystalline silicon wafer
Inventor: YOKOYAMA TAKASHI
IPC: H01L21/02
Filed: 1982-03-29
Abstract: PURPOSE:To manufacture the wafer of arbitrary shape without labor, to obtain a solar  cell, in which module charging density can be increased, simply while facilitating heating and to recover a silicon melted liquid by discharging the melted liquid being supplied excessively by the centrifugal force of a turntable mechanism and forming a thin  layer of the melted liquid onto a wafer forming plane and cooling and solidifying the  thin layer. CONSTITUTION:When the melted liquid of a silicon parent material is supplied to the  central section of the wafer forming plane 15, the plane is set up into a proper vessel,  and an inert gas is enclosed. The melted liquid supplied is fluidized and spread onto  the whole surface of the wafer forming plane 15 formed by a release agent 16 by the  revolution of the turntable mechanism, and the melted liquid flows in onto an excessive  silicon discharge plane 14 when the melted liquid is further spread. However, since  the plane 14 is formed by boron nitride, has no moistening property with all substances  and is stable even at a high temperature, the melted liquid to be discharged can be  recovered and reused because it is scattered by centrifugal force and solidified on the  plane 14, the thin layer 19 of the melted liquid extending over the whole surface is  formed onto the wafer forming plane 15 by the melted liquid being supplied, and  solidified through cooling by natural cooling, forced cooling, etc., and products are obtained.

Title: Heating and cooking device
Inventor: NISHIMURA NOBUICHI
IPC: F24C7/02
Filed: 1982-03-29
Abstract: PURPOSE:To improve the finish of cooked food by a method wherein a heating and cooking device for controlling intermittently the energization of a heater unit is constructed such that the energization time of the heater unit is controlled in response to a surrounding temperature. CONSTITUTION:The surrounding temperature around a main body 11 is sensed by a temperature sensor 19 and fed to a control circuit 17. When the surrounding temperature 19 is a reference temperature TS1, the rate of energization time T1 of the heaters 13, 14 and the rate of turning-off time T2 are made substantially equal to each other and an intermittent energization of the heaters is performed. If the surrounding temperature 19 is lower than the reference temperature TS1, the control circuit 17 calculates the rate between the energization time T1 and the turning-off time T2 and causes the energization time T1 to be extended. In turn, if the surrounding temperature 19 is higher than the reference temperature TS1, the energization time T1 is made shorter. With this arrangement, it is possible to eliminate an effect of the surrounding temperature and improve the finish of the cooked food.
