Title: Connection confirming system
Inventor: OKA NOBUHIRO
IPC: H04L12/54
Filed: 1981-09-02
Abstract: PURPOSE:To shorten the wasteful line connection time to economize in the line use charge, by recognizing the state of the receiving side in the transmitting side when an answer tone signal which is transmitted selectively in accordance with the transmission-enable-state or the transmission-disable-state is received. CONSTITUTION:Data transmitted from an input device 6 to a data transmission controlling circuit 7 is converted to a serial data train in terms of time by a serial-parallel/parallel-serial converting circuit 8 and is transmitted. Received data is converted to a parallel data string by the circuit 8 and is outputted to a circuit 11 after controls such as error detection in a data reception controlling circuit 10. In circuits 7 and 10, two kinds of frequency from an MODEM which is not shown in a figure are distinguished from each other for persons by the difference of tone color and for machines by the difference of code string, or intervals of transmission times of two kinds of transmission code are distinguished from each other for persons by the difference of tone color and for machines by the difference of interval of transmission times of transmission codes. Thus, the state of the receiving side is detected in the transmission side in the early stage by the answer tone signal from the receiving side.

Abstract: PURPOSE:To execute high speed switching and to detect gas at a high speed and with high accuracy by modulating a laser light of different wavelength by a signal of a different frequency and changing its intensity. CONSTITUTION:A laser light of a wavelength which is absorbed by measuring gas and a laser light whose wavelength is a little different and which is not absorbed are emitted from oscillators 1, 3, respectively. Subsequently, oscillators 5, 6 are oscillated, high frequency signals of frequencies f1, f2 (Hz) are sent to driving devices 2, 4, respectively, and a modulation is given to intensity of the laser light. These layer light beams are projected to a scattering part 16, and the laser light which has been scattered and reflected is made incident on a semiconductor photosensor 10 to which a voltage of a frequency fD has been applied. In such a way, when gas exists in an optical path of the laser light, the amplitude of an electric signal of a frequency ¦f1-fD¦ becomes relatively smaller than that of ¦f2-fD¦. By comparing this difference by an amplitude comparator 15, existence of gas and its concentration are measured.

IPC: G02F1/1335
Filed: 1990-05-28
Abstract: PURPOSE:To decrease the leakage of light from the non-display parts of an optical shutter and to form the color filter layer of the liquid crystal display device having a high display grade by boring windows on the inner side of the parts facing transparent electrodes on the opposite side to form striped patterns with the windows, forming color filters on metallic thin films and the transparent electrodes on the inner side of the windows, applying a photosetting black mask material over the entire surface, and exposing the material to cure the black mask material of the parts exclusive of the parts on the color filters. CONSTITUTION:The transparent electrodes 13, the metallic thin films 11 and resists 12 are formed in the form of stripes on a glass substrate 9. The windows are bored by photoetching in the striped resists 12 on the inner side of the parts facing the transparent electrodes on the opposite side arranged in the direction orthogonal with the electrodes 13, by which the striped patterns with the windows are formed. The color filters are then formed by an electro deposition coloring system on the striped metallic thin films with the windows and the electrodes 13 on the inner side of the windows. The photosetting black mask material is thereafter applied over the entire surface and is exposed to expose and cure only the black mask material on the glass substrate. On the other hand, the black mask material applied on the color filters is removed without curing the material. The transmission quantity of the light from the non-opposite parts of the transparent electrodes is then decreased to substan tially zero by the simple method. The contrast of the liquid crystal display device is improved and the display grade is enhanced.
