Title: Electron beam irradiation device
Inventor: KINOSHITA SHINOBU
IPC: G21K5/04
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To attain running cost reduction and life extension of device by providing a processing means for decomposing ozone generated during irradiation of electron beam in an atmosphere containing oxygen. SOLUTION: When electron beam is irradiated to an irradiation space 22 in an irradiation chamber, ozone and nitrogen oxide are produced. If moisture exists in the space, the nitrogen oxide is solved in water to be nitric acid. The gas in that state is sucked into an exhaust port 41 and introduced in a device 42 absorbing and processing nitrogen oxide and nitric acid. In the absorbing device 42, water as absorbing liquid 45 is filled to absorb nitrogen oxide and nitric acid. As ozone is simultaneously produced in the case of electron beam irradiation and nitrogen monoxide is oxidized to be nitrogen dioxide, and so the nitrogen oxide in the exhaust gas is absorbed in the absorption liquid 45. The exhaust gas after passing the absorption device 42 is introduced in an ozone decomposition device 43 and ozone is decomposed. It is exhausted through a fan 44 or a pump for exhausting.

Abstract: PURPOSE:To reduce an error at the extraction of character broadcasting signal to less than a specific value without using a high clock frequency, by using a polyphase clock generation part, automatic data extraction phase discriminating part, and clock phase selection part. CONSTITUTION:A polyphase clock generation part uses buffers 17 and 18 as delay elements and when a reference signal of 5.73MHz is inputted from an input terminal 16 to buffers 17 and 18, a clock of 5.73MHz shifting in phase by the delay time of one buffer is obtained. While polyphase clocks are supplied from the buffers 17 and 18 to a latch 19, a signal STX synchronizing with a bit synchronizing signal is supplied from an input terminal 31. When the signal STY is inputted at some timing, polyphase clocks 23-30 are latched by the output of the latch 19 and inputted as an 8-bit parallel signal to the ROM20. At this time, the clock phase selection part consisting of a multiplexer 21 and an NAND circuit 22 determines 4-bit of the data terminal output of an ROM20 so that the clock 28 is selected among the polyphase clocks.

Title: Incident angle detector
Inventor: NAKAYAMA YOSHINOBU
IPC: G11B7/09
Filed: 1988-03-08
Abstract: PURPOSE:To detect an angle shifted from the vertical direction of light and also to detect title to an optical disk surface by using a grating as a photocoupler. CONSTITUTION:An optical waveguide 5 is formed on a substrate 1 and a grating 6 having the optimum connecting conditions in the direction shifted from the vertical direction is formed on the surface of the waveguide 5. Then two photodetectors 3 and 4 are set at the symmetrical positions centering on the grating 6. The difference is secured between the outputs of both photodetectors 3 and 4 and the angle shifted from the vertical direction of the light is detected as a control output signal (g) by an amplifier 8. Thus the incident light made incident from the grating 6 is led to the waveguide 5 and detected as the guidewave light by a photodetector 3. Then the difference of the light quantity is obtained by the amplifier 8 and the signal (g) is transmitted. As a result, the angle of the incident light can be controlled against the vertical direction of the surface of the substrate 1. Thus it is possible to apply such an incident angle detector to an optical pickup, etc., and to execute the control so that the incident light is always kept vertical to the surface of an optical disk. In other words, the tilt can be detected to the surface of the optical disk.
