Title: Mos integrated circuit
Inventor: TAKAHASHI KAZUKIYO
IPC: H01L29/78
Filed: 1979-02-22
Abstract: PURPOSE: To obtain a low power consuming and high speed MOS.IC by a method wherein the MOS.IC is composed of a positive voltage-delivering power source, a control signal source and a DAS.MOS transistor.  
     CONSTITUTION: A control signal source 200 is connected to the gate of a DAS.MOS transistor 201, the source of a transistor 201 is connected to a power source 202 and the drain is connected to a load circuit 1000 through an output node 99. The load circuit 1000 is connected to the power source 201 through the earth. In this construction, a positive voltage is applied from the signal source to the transistor 201, and a positive output voltage of power source 202 is applied to the load 1000. In this case, when the drain potential is higher than the source potential, the transistor 201 operates as an enhancement type. But if the potential relation is reversed, the threshold voltage of gate becomes nearly 0 volt. Therefore when the voltage of the signal source 200 and of the source 202 are equal, the voltage of the circuit 1000 becomes equal to the voltage of power source, and the circuit 1000 operates in high speed.

Title: Range hood
Inventor: OGINO KAZURO
IPC: F24F7/06
Filed: 1988-01-29
Abstract: PURPOSE:To axially convert the direction of suction air which enters an impeller and thereby prevent the generation of abnormal noise, by providing an axial ventilation fan fixed to a side plate of a hood, installing a filter to an opening of said hood, and a shielding plate between a suction port of said ventilation fan and filter. CONSTITUTION:The air present on the left half section as viewed from the front of a ventilation fan 2, is sucked up in the direction opposite to the rotating direction of an impeller 7 where an angle of incidence to a blade is increased, thereby exfoliating the air and generating abnormal noise intermittently. However, between the ventilation fan 2 and a filter, a shielding plate 11 is mounted to an innermost plate 4 on the left half section as viewed from the front of the ventilation fan 2. Therefore, the suction air 8 present on the left half section as viewed from the front of the ventilation fan 2, is collided with the shielding plate 11 when passing through the side of the ventilation fan 2, moves far from the ventilation fan 2 once flowing along the shielding plate 11, and is sucked up into an impeller 7, turning into an axial flow. It is, therefore, possible to reduce an angle of incidence, and eliminate the exfoliation of air and the generation of abnormal noise.

Title: Lens barrel
Inventor: DOI TAKAHIRO
IPC: G02B7/04
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To obtain the sure operation of a moving frame by suppressing its unnatural operation without adding any complicated mechanism by moving the moving at a low speed before the moving frame reaches a turnabout nodal point where it moves from a setting operation area to a zooming operation area and to make the lens barrel itself small-sized. SOLUTION: A CPU 60 drives a driving source 51 such as a motor by controlling a motor drive circuit 65 and a photointerrupter(PI) 66 starts monitoring rotation pulses of the driving source 51. When it is judged that a cam follower moves to nearby a turnover nodal point to a key groove, the rotation of the driving source 51 is reduced in speed to stop it. The CPU 60 reverse the driving source 51 for a specific short time by controlling the motor drive circuit 65 to surely correct an unnatural attitude of the moving frame 2. Then the driving source 51 is driven forward at a slow speed to allow the moving frame 2 to pass the turnover nodel point while holding its attitude normal, and the cam follower is moved smoothly to the key groove.

Title: Method and device for encoding digital image data
Inventor: ABURAHAMU MOORENAARU
IPC: G06T9/00
Filed: 1992-02-06
Abstract: PURPOSE: To realize extensive encoding by substituting continuous data groups in one block for a code containing the number of the data groups in a continuous part and executing similar substitution when a difference signal with the data group of the same position of a preceding block satisfies a prescribed condition. CONSTITUTION: In the step 109 of a series of procedures, the continuous data groups of a pixel in a raster line is substituted for the run length code containing the number of the data groups in the continuous part. Substitution is executed by the similar code at the time of approximation according to whether the difference with the data group of the same position of the preceding raster line is approximated to the position in such a way that it satisfies a linear relation. The preceding line is made into the run length code by combining it with the run length code of one line in parallel. In a step 114, the effective code is selected. Thus, a series of multiple pixels having the same value in the direction of a column are extensively encoded by the method and image data is much more compressed.
