Title: Tv transmitter/receiver
Inventor: HAMADA FUMIO
IPC: H04N7/16
Filed: 1990-07-20
Abstract: PURPOSE:To improve the secrecy of transmitted waves by providing a polarity switching circuit to detect a signal having polarity inversion information, to invert the polarity according to this signal and to return it to original one. CONSTITUTION:For an inputted video signal, the synchronizing signal of the video signal is detected by a synchronizing signal detection circuit 1 and at arbitrary time, the polarity of the video signal is inverted by a polarity switching circuit 3 through a control circuit 2. A pilot oscillation circuit 4 is modulated simultaneously with inverting the polarity of the video signal, and information showing the inversion of the polarity is transmitted to a reception part. At the reception part, the polarity of the video signal is decided by a pilot detection circuit 5 and returned to original one by a polarity switching circuit 7 through a control circuit 6. Thus, by adding a simple circuit, the low- priced TV transmitter/receiver with secrecy can be obtained.

Filed: 1989-07-25
Abstract: PURPOSE: To prevent the dwindling of reflectance against a large incident angle of light by providing a cubic corner having a non-vertical triangle face and giving a specified angle for the vertical face of a base. CONSTITUTION: In a reflection element 20, the cubic corner 34 is formed by sequare faces 42 and 25 which are substantially vertical, the triangle face 28 vertical against the esquire faces 24 and 25 and the triangle face which is not vertical against the vartiacle face of the base 22 and which has an angle α. The square faces 24 and 25 have the rectangular based of length L and crossing lines Y and the relation of Y<L is given. The angle α is in the range of Sin α=0.25/n to 1/n for the refraction factor n of the reflection element 20. In the reflection elements t20, the respective bases 22 are arranged so that they are adjacent face layers and a non-orthogonal corner 21 is formed between the non-vertical triangle face and the square faces 24 and 25.  Even if the incident angle of light becomes large by the setting of the angle α, the dwinling of the reflectance can be prevented.

Title: Production of phase phase shift mask
Inventor: SATO JUNICHI
IPC: G03F1/68
Filed: 1992-07-21
Abstract: PURPOSE:To make it possible to etch a transparent film for forming the phase shifters of the phase shift mask by a dry etching. CONSTITUTION:The oxygen content of transparent SiOx films 3 formed to coat Cr light shielding films 2 formed periodically on a glass substrate 1 is set slightly higher than that of a glass substrate 1. Free S (sulfur) is dissociated and formed from S2F2 if the transparent SiOx films 3 are etched by using S2F2. This S is burned and removed on the expose surfaces of the transparent SiOx films 3 from which a large quantity of O atoms are released by an ion sputtering effect and, therefore, the etching is not hindered. On the other hand, the S deposits on the resist mask 4 or light shielding Cr films 2 which hardly release the O atoms or on the exposed surface of a glass substrate 1 which release the O atoms in a smaller amt. A high selection ratio is thus assured. The deposited S is simultaneously removed at the time of ashing the resist mask 4.
