Title: Absolute encoder
Inventor: KOMATSU MASAO
IPC: G01D5/36
Filed: 1990-06-08
Abstract: PURPOSE:To make it possible to detect an absolute pattern at high resolution even if the absolute pattern is a single track by aligning the combinations of a plurality of neighboring identifying regions so that the combinations do not become the same combination along the entire length of a detecting region. CONSTITUTION:Transparent regions (a) and opaque regions (b) which are the identifying regions obtained by dividing a circumference into 16 regions are aligned so that the combinations of the neighboring four identifying regions do not become the same combinations along the entire circumference of an absolute pattern 2. A timing-pulse generating track 3 is formed on a code disk 1 in the concentric-circle pattern with the pattern 2. Detectors 9 and 11 are connected so that the detected signals are inputted into a measuring device. The track 3 and the detector 11 have the position relationship so that a timing- pulse signal is outputted under the state wherein the detector 9 faces the approximately central part of the identifying regions of the pattern 2. The absolute signal from the pattern 2 is read with the measuring device. When the absolute signals of continuous bits are read, the phase of a body to be measured is detected with the position of the original point of the detector 9 as a reference based on the signal.

Title: Vehicle having steering unit
Inventor: ICHIMURA KAZUHIRO
IPC: F02D29/02
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent rapid takeoff in a state where the tires are steered by detecting takeoff and setting the engine revolution at a lower value than a value set and controlled by a running operation member when a steered amount is equal to or greater than a predetermined value and a certain conditions are met. SOLUTION: When tires are steered by a large amount by a steering wheel 21 at takeoff of a wheel type hydraulic shovel, a controller 1 calculates a target revolution, which is an idle revolution, regardless of running pilot pressure and sets an engine revolution such that it becomes equivalent to the target revolution. That is, at takeoff, when a steer amount of a hydraulic power steering unit is above a value at full stroke, the engine target revolution is controlled to be set at substantially idle revolution. Therefore, there is no fear of the wheel type hydraulic shovel taking off rapidly when taking off with the tires being steered by a large amount.

Title: Gas laser device
Inventor: TAKANO NORIO
IPC: H01S3/134
Filed: 1978-12-01
Abstract: PURPOSE:To prevent a laser tube from damage, causing to an overcurrent in an abnormal state, by providing a discharge current control feedback circuit with a bypass circuit for limiting a discharge current when laser light changes sharply. CONSTITUTION:When dust or the like enters into light resonators 7, 7' or a beam splitter 8 and laser light 13 decreases sharply, by photoelectric output voltage V1 of a light detector 6 falls drastically and the output voltage of a comparison amplifier 3 rises sharply. At that time, a transistor Tr2 is turned on and the discharge current of a laser tube 9 increases sharply. Since the current detection terminal voltage V2 of a resistor 18 rises due to the sharp increase in the discharge current, the difference between the voltage Vs2 of a reference power source 14 and the current detection terminal voltage V2 decreases and the output voltage of another comparison amplifier 19 drops. As a result, the output voltage of the former comparison amplifier 3 is applied to the latter 19 through a resistor 15 and diodes 16, 17, the base voltage of the transistor Tr2 falls and the discharge current of the laser tube 9 decreases. In an abnormal state as mentioned above, the difference between the voltage Vs2, V2 is amplified and then applied to the base of the transistor Tr2 and constant current control is effected to eliminate the difference.

Title: Air flow deflection device for air conditioner
Inventor: UCHIDA YOSHIAKI
IPC: F24F13/062
Filed: 1985-07-08
Abstract: PURPOSE:To prevent a reduction of air flow due to its hitting the side walls even if the air flow is greatly deflected in the lateral deflection and enlarge the angle of lateral air flow deflection by shaping the side walls of the outlet grill into curved walls expanding toward the direction of outlet to widen the areal size of the outlet. CONSTITUTION:Vanes 9 for lateral air flow deflection rotatably disposed in the outlet passage 3a of the outlet grill 3 are formed in the shape of arc. Side walls 3b of the outlet grill 3 are gradually widened toward the direction of outlet in conformance to the direction of the curved part of the lateral air flow deflection vanes 9. The reason why the lateral air flow deflection vanes 9 are curved is to deflect the air flow by the Coanda effect in cooperation with the curvature of the side walls 3b. When the air blown by a fan (windward) is laterally deflected by the lateral air flow deflection vanes 9 in the outlet passage 3a, the air will flow to the leeward side along the side walls 3b of the outlet, resulting in a significant improvement of reduction of air flow.

Title: Ccd solid-state image pickup element
Inventor: KATOU NAOKI
IPC: H04N5/341
Filed: 1991-06-21
Abstract: PURPOSE:To prevent the occurence of the point defect of white/black by forming a higher level potential grade difference than a previous high level potential under a transfer electrode of which potential comes into a higher level in the periods of an initial state and reading-out. CONSTITUTION:The high impurity concentration of a vertical register 2 under a first transfer electrode G1 is set to be higher than the high impurity concentration under the other transfer electrodes G2-G4. When the same potential is impressed to the electrode G1-G4, potential under the electrode G1 is set to be higher than that under the other electrode G2-G1. Namely, the potential grade difference ph is formed under the electrode G1. Thus, smear charge in the register 2 is accumulated at the difference ph which is formed under the electrode G1 of which potential comes into the high level in the periods of the initial state and reading T and smear charge, etc., becomes absent under the other electrode G2-G4. Thus, the point defect of white/black owing to the variance of smear charge, etc., does not occur.
