Title: Detection data analyzer
Inventor: YOSHIKAWA HISAO
IPC: B60R16/02
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain an analyzer capable of easily processing plural detection data and eliminating the necessity of plural recording means even when various detection data exist, by acquiring detection data temporarily stored in a data detection part by a data processing part, and after processing the data, recording the processed data in a recording means. SOLUTION: Detection data are temporarily stored in the data detection part and the data processor acquires the stored detection data, processes the acquired data and then records the processed data in the recording means. Namely the analyzer records detection data obtained from a detection sensor in a dual port memory 44 through a shaping circuit 41, an A/D conversion circuit 42, a data control circuit 43, and a 1st port 44a. Since the detection data can be optionally read out through a 2nd port 44b, a central processing unit(CPU) 56 properly reads out and acquires the detection data through a bus 59 connected to the 2nd port 44b, applies necessary processing to the acquired data and records the processed data in a flash memory 52.

Title: Semiconductor integrated circuit device
Inventor: HAYASHI YASUYUKI
IPC: G01R31/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device wherein a simultaneous change in output drives of an LCD driver IC is prevented, and a fluctuation in power supply potential and ground potential is suppressed, so that a stable test is possible even when electric characteristics of a power supply line due to a measurement system at the time of testing are severe. SOLUTION: Time from a signal change being a trigger for an output signal to an output change, that is delay time, is constituted to be different for each of output drivers 1 or for each group of output drivers divided into several groups based on a test control signal of an external input test terminal 5. Thus a simultaneous change in the output drivers 1 is prevented and a fluctuation in power supply potential and ground potential is suppressed. At the time of actual use, if the external input test terminal 5 is opened, a pull-down resistor circuit 6 makes a state where the output drivers 6 can simultaneously change, resulting in use without problems. Therefore, even a LCD driver IC having numerous output drivers 1 with high drive voltage can be tested in a stable state while preventing the output drivers 1 from changing simultaneously.

Abstract: PURPOSE: To provide fine timing recovery to a QAM MODEM receiver by minimum CPU power and short feedback delay. CONSTITUTION: The QAM MODEM receiver executes fine timing recovery for base band signals sampled on two complex points per code. The algebraic symbols of 2nd derivatives of these base band signals are estimated based on the fine timing recovery information. These symbols are individually calculated about a real number axis and an imaginary number axis and used for locally determining the rugged states of the base band signals. When the local determination is stored over a proper time interval, the maximum/minimum of the base band signals and a relative sampling point position are globally determined. A correction command is supplied to the analog front end 12 of a MODEM based on the global determination and timing is advanced or delayed.

Title: Optical repeater
Inventor: KIYOTA SHINJI
IPC: H04B10/07
Filed: 1982-11-11
Abstract: PURPOSE:To simplify a gain controlling circuit and to reduce the number of steps of an amplifier by using an optical amplifier for controlling so that intensity of an optical signal outputted from a laser medium by an electric signal becomes constant. CONSTITUTION:When an optical signal is inputted to a laser medium 1, the optical signal is amplified by the laser medium 1, and the amplified optical signal is outputted through a Y branching circuit 2. In this case, a part of light is made to branch by the Y branching circuit 2, photodetected by a pin photodiode 3, converted to an electric signal being proportional to intensity of the light and inputted to a gain controlling circuit 4. The gain controlling circuit 4 amplifies the inputted electric signal and makes a direct current flow to the laser medium 1 in proportion to intensity of the light. In this case, if an optical signal of an output of the laser medium 1 is large, the current flowed to the laser medium 1 by an output of the gain controlling circuit 4 becomes large, and an amplification factor of the laser medium 1 operates so as to go down. In this way, an automatic gain adjusting circuit is formed, and even if a level of an inputted optical signal is varied, intensity of an outputted optical signal becomes constant.

IPC: G03G5/12
Filed: 1984-09-20
Abstract: PURPOSE:To easily obtain a polychromatic image through single-time exposure by exposing a photosensitive body equipped with filters which transmit visible light in a short-wavelength, an intermediate-wavelength, and the entire wavelength range to an image, executing an entire-surface exposure using light passed through only one kind of filter and a development, and repeating this process for other filters. CONSTITUTION:The photosensitive body consists of a conductive base 1, photoconductive layer 2, and a transparent insulating layer 3 including the filters which transmit visible light in the long-wavelength range (R), intermediate-wavelength ragne (G), and short-wavelength area (B). When the entire surface is charged electrostatically and positively by an electrostatic charging electrode 4, a positive charge is generated on the surface of the layer 3 and a negative charge is induced at the boundary between the layers 2 and 3. Image exposure is carried out while negative discharging is performed by an electrostatic charging electrode 5. Then, the charge in the layer 2 of a white image part W disappears. Then the entire surface is exposed to light L1 transmitted through only the R filter part to form a potential pattern on the surface of the R filter part. This is developed with cyan toner. Then, discharging is performed by the electrostatic charging electrode, and then entire-surface development using light transmitted through the G or R filter part and development are carried out repeatedly to form the polychromatic image.

Abstract: PROBLEM TO BE SOLVED: To facilitate manufacturing and minimize material loss when a defective article is produced during manufacturing time by mounting fittingly an elastic member over a joining area between a lower post whose upper part is projected on the ground and whose base part is buried underground and an upper post and mounting a cylinder-shaped elastic body on the outside of the upper post and the lower post. SOLUTION: An elastic member 3 is fittingly mounted over a joining area between a lower post 1 whose upper part is projected on the ground and whose base part is buried underground and an upper post 4. A cylinder-shaped elastic body 5 is mounted on the outside of the upper post 4 and the lower post 1. The lower post 1 is connected to the upper post 4 so that they may rock. Therefore, when a car or the like comes into contact with the upper part of the post and external force is applied, the upper post 4 and the elastic body 5 are rocked with the elastic force of the elastic member 3 so that the impact force may be relaxed.  Since the elastic member 3 is not integrated with the posts 1 and 4 or the elastic body 5, the need for insert molding or the like is eliminated, thereby facilitating the manufacture and minimizing material loss when defective articles are produced during manufacturing time.
