Title: Multi-value picture input device
Inventor: TAKAHASHI YOTA
IPC: H04N1/401
Filed: 1989-12-28
Abstract: PURPOSE:To attain gradation expression in matching with each original by storing once a picture data of an original into an image memory. CONSTITUTION:When a scanning unit 24 is set to a home position, a motor control circuit 47 is controlled to apply subscanning to the scanning unit 24 by the prescribed quantity and the position for read scanning is placed beneath of a standard density plate 28. A multivalue input device in this state reads a data by one scanning line and it is used as an actual measured value of the standard density plate 26 and stored in an actual measurement value storage area 44A. Then a CPU 41 moves the scanning unit 24 up to a scanning start position of an original 22 and the picture is read with a prescribed resolution from the position. The result of reading implemented for each line is AD- converted into 64-stage of gradation levels and stored sequentially in an image memory 51. Thus, even when the density range of an original is comparatively narrow, the density difference is clearly reproduced.

Abstract: PURPOSE:To provide a seal unit of excellent quality by providing a plurality of injection gates with a almost equal space in the peripheral location in a thin thickness part of the seal unit, so as to prevent improper connection of a weld part and breaking of a center part generated in the thin thickness part. CONSTITUTION:Injection gates 4, 4 opposed with the center part serving as a reference are provided in a peripheral part 8 from a thin thickness part 2 of a seal unit. Melted resin is pressurized to pass through the injection gates 4, 4 from a runner 6 and branch runners 5, 5 into a cavity.

The resin is cooled a little in the thin thickness parts A, A to decrease an infiltrating speed with a flow detouring a little, and when a peripheral part of the thin thickness parts A, A is filled, the resin, increasing an internal pressure, flows into the center part first from right/left positions B, B which are parts of the highest fluidity. Here by the cavity internal pressure, the resin in a part of first reaching the thin thickness parts A, A also flows into the center part with a delay. After cooling the resin solidified, it is removed from a metal mold by cutting off a gate part.

Title: Combination of surface emission laser light source and photodetector
Inventor: RI YOUKI
IPC: H01L31/12
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a combination of a light source employing a VCSEL and a photodetector. SOLUTION: In order to regulate the quantity of light outputted from a light source 22 employing a VCSEL, spontaneous emission scattering to the side face of light source 22 is received and converted into an electric signal which is then employed for controlling the output of light source 22. A monitor photodetector 24 is arranged around the light source 22 for that purpose. The photodetector 24 has circular inner side face facing the light source 22 and absorbing the spontaneous emission and polygonal outer side face having a plurality of edges. Consequently, the majority of spontaneous emission absorbed by the photodetector 24 does not pass through the outer surface but reflected inward and the passage of absorbed spontaneous emission is elongated in the photodetector 24 thus increasing the quantity of light to be converted into electric signal.

IPC: G06T7/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To recognize the characteristic of an original with high accuracy and also to increase the processing speed of an image processor with high accuracy when the density of image signals are corrected based on a prepared density correction table. SOLUTION: The image signals, i.e., the original read data, are inputted via an input terminal 1. A density value histogram is produced by a feature data extraction circuit 3 to show the pixel number (frequency) of each image density in response to the image signals stored in a memory 2. The circuit 3 extracts the density value of the highest frequency and the rate obtained by dividing the pixel number of the said density value by the number of all pixels that produced the said histogram as the feature data which are used for recognition of the original characteristic. Based on these two feature data, the characteristics (features) of such originals as characters, photos, etc., are recognized. Then a density correction table selection circuit 4 selects a density correction table in response to the recognized original.  A density correction circuit 5 corrects the density of those input image signals based on the selected density correction table and outputs the corrected image signals via an output terminal 6.

Title: Signal processing circuit
Inventor: YASUDA YUKIHISA
IPC: H03K3/0233
Filed: 1992-12-25
Abstract: PURPOSE:To prevent power supply voltage from being changed even at the time of signal voltage limiting operation by limiting the voltage of a signal input terminal to the upper limit value or less when it is increased in the positive direction and limiting the voltage to the lower limit value or more when it is increased in the negative direction. CONSTITUTION:The 1st and 2nd transistors(TRs), i.e., an npn TR 5a and a pnp TR 5c, are connected between a signal input terminal 8 and a reference input terminal 9, and when signal voltage exceeds its upper limit value, the TR 5a is turned to a conductive state and a current is allowed to flow from the terminal 8 to the terminal 9. In this case, the potential of the terminal 8 is limited to the upper limit or less. When the signal voltage is reduced to less than the lower limit value, a pnp TR 5b is turned to a conductive state and a current is allowed to flow from the terminal 9 to the terminal 8. In this case, the potential of the terminal 8 is held at a level more than the lower limit value. Thereby the power supply voltage and the reference voltage are not changed independently of the value of power supply impedance 100a and stable operation can be attained.
