Patent JP-H03104175-A (JP)
Title: Semiconductor photo detector
Inventor: MIZUSHIMA YOSHIHIKO
IPC: H01L31/10
Filed: 1989-09-18
Abstract: PURPOSE:To reduce dark current by irradiating the interface or metal and semiconductor with a light whose wavelength is longer than the wavelength corresponding to the energy gap of a substrate. CONSTITUTION:The interface of metal 2 and a semiconductor substrate 1 is irradiated with an incident light 6 of long wavelength. Electron emitted from the contact interface of the metal 2 and the substrate 1 by the incident light 6 is subjected to high speed drift transition by a high electric field applied between electrodes. Hence a very high speed optical signal also can be received. When the wavelength of a light is shorter than 1.4-3. lmum which correspond to the barrier height of 0.4-0.9eV formed by using Si or GaAs as the semiconductor substrate, the light can be sufficiently received. Hence a very high speed photo detector for long wavelength use or OEIC can be manufactured by using the substrate like Si or GaAs whose semiconductor process technique has been established, and further the dark current can be reduced.

Title: Monitor system for two-way catv transmission line
Inventor: YOSHIDA MITSUSAKU
IPC: H04B3/46
Filed: 1988-09-27
Abstract: PURPOSE:To confirm a line error correctly by allowing a center to send an individual number of a CATV terminal equipment managed by the center and an individual number of a CATV terminal equipment not connecting to a transmission line respectively and the center to analyze a reply data from each terminal equipment, the presence of a carrier level of a terminal equipment having no reply data and its no reply state so as to monitor the state of the transmission line. CONSTITUTION:With an input of a data signal from, e.g., a communication controller 2 to a branching filter 6, it outputs the signal to a data signal transmission reception analysis section 10 via a data signal reception exchange section 8. A terminal number setting section 9 sets its own individual number, and upon the receipt of a data signal from the data signal reception exchange section 8, the data signal transmission reception analysis section 10 compares an individual number of the data signal with the individual number set by the terminal number setting section 9, gives an output to a reply data signal transmission conversion section 7 when both the individual numbers are coincident and the resulting output is sent to a transmission line 5 via the branching filter 6. The center equipment 1 analyses the reply data as presence of an error in a normally received data or no reply or the like. Thus, a line error is discriminated.

Title: Driving method for liquid crystal element and liquid crystal device using the driving method
Inventor: IWASAKI MANABU
IPC: G09G3/36
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent image extending over a wide temperature range and to accelerate a frame frequency. SOLUTION: When the temperature of a liquid crystal element is lower than the reference temperature, the liquid crystal element is driven by impressing a voltage waveform shown by a code 30 or a code 31 in the figure on liquid crystal. Since the voltage waveforms 30 and 31 are provided with a term that an electric field is not impressed on the liquid crystal, a driving margin is widened, and crosstalk is hardly generated and a picture element is hardly inverted. When the temperature of the liquid crystal element is higher than the reference temperature, a voltage waveform shown by a code 32 is impressed on the liquid crystal. However, since the waveform 32 is not provided with the term that the electric field is not impressed on the liquid crystal, the frame frequency is accelerated.

Title: Optical disk driving device
Inventor: NAKAYAMA SHIYUU
IPC: G11B19/20
Filed: 1990-09-14
Abstract: PURPOSE:To cope with even large vertical shake by detecting the angle of incidence of a light beam on an optical disk and inclining a spindle in such direction that the angle of incidence is 90 deg.. CONSTITUTION:A tracking servo circuit 16 operates the difference signal between signals outputted from two photodetectors 12a and 12b to output a servo signal proportional to the extent of deviation of the tracking position. Consequently, a spindle 1 is inclined by an inclining motor 6 in such direction that a laser beam 7 is made perpendicularly incident on the signal face of an optical disk 3. When the laser beam 7 is made perpendicularly incident on the signal face of the optical disk 3, the signal face of the optical disk 3 is placed in an about center of the servo range of a tracking servo circuit 16, and the optical axis of the laser beam 7 coincides with a recording track to correct the tracking deviation. Thus, the burden of a servo system is reduced to record/reproduce normal information.

Title: Method for converting plotting data
Inventor: HATA KENJI
IPC: H01L21/027
Filed: 1991-09-24
Abstract: PURPOSE:To perform pattern plotting with an electron beam which can suppress the increase of patterns to be plotted to a necessary minimum by dividing a wiring pattern spread over a plurality of fields by the joints of the fields and plotting the pattern by fields. CONSTITUTION:A linear pattern is wired from a starting point (xs, ys) to an end point (xe, ye). Regarding the pattern, the equation of the straight line passing through the starting and end points of the linear pattern is first found. Then the intersections 8, 9, 10, and 11 of the straight line with the joints of four fields are found. Among the four intersections, the intersection 10 between coordinates of the starting and end points is found. Then the data of the straight line are divided at the intersection 10 by using the segment from the starting point to the intersection 10 as the plotting data of an NM field. Thereafter, the position of the straight line to the next field is decided by increasing/ decreasing the values of the N and M by adopting the intersection 10 as a new starting point. By repeating such process, the pattern from the finally selected intersection to the end point is used as the plotting data of the field in which the end point exists.
