Filed: 1993-12-21
Abstract: PURPOSE:To obtain continuous rotary motion by balancing weight at places different in distance to generate rotation. CONSTITUTION:The distance to a meshed part A between a second locking gear 13 and a free gear 5, and the distance to a meshed part B between a ring gear 3 and an operating gear 8 from a shaft 21 as the center are made equal to balance load applied to the left ends of the free gears 5, 5 with load applied to the left end of the operating gear 8. The distance to a meshed part C between a third locking gear 22 and the free gear 5 from the shaft 21, and the distance (d) to the right end of the operating gear 8 from a shaft 81 are made equal to balance load applied to the right ends of the free gears 5, 5 with load applied to the right end of the operating gear 8. In the case of the operating gear 8 being about to rotate clockwise around the shaft 21, the clockwise rotation of the operating gear 8 around the shaft 21 is impeded by the presence of a first locking gear 1, so that the operating gear 8 is rotated around the shaft 81.

IPC: H04N1/40
Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To provide the resolution conversion method of binarized picture data, which can improve picture quality in a part where concentration is comparatively low. SOLUTION: In the method, the resolution of binarized picture data is converted at every range being the object of a processing in a size whose vertical direction is N pixels and lateral direction is M pixels. A dither processing is executed by using a dither matrix in the size whose vertical direction is the N pixels and lateral direction is 2M pixels with respect to a concentration reference range in the size where the vertical direction which includes the range being the object of the processing in the center of width is the N pixels and the lateral direction is the 2M pixels. Binarized picture data of one pixel, which is obtained by the dither matrix, are allocated to the pixel whose horizontal direction is 1/2. Thus, the resolution of binarized picture data with respect to the range being the object of the processing is converted.

Abstract: PROBLEM TO BE SOLVED: To reduce the resistance between the gate and source electrodes to make the high frequency characteristics superior by forming a source electrode on the opposite surface of a carrier run layer to its surface on which a gate electrode is formed. SOLUTION: A field effect transistor 100 comprises a gate electrode 105 and a drain electrode 104 laminated on one surface of a carrier run layer 102, and a source electrode 106 laid on the other surface of the run layer 102, so that the source and gate electrodes 106, 105 are opposed and partly overlapped. Owing to this structure, no effect of a depletion layer due to formation of the surface level will arise on the relation between the source and gate electrodes 106 and 105, and the distance between the source and gate electrodes 106 and 105 is shortened. Even in operating the field effect transistor in an enhancement mode, the resistance between the source and gate electrodes 106 and 105 can be reduced to obtain greatly superior characteristics.

Title: Control method for main spindle head
Inventor: AKAMATSU YOSHIAKI
IPC: B23Q3/155
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To protect the damage of a protective bearing when a used tool is extracted from a main spindle by moving the main spindle to the front side in the axial direction at the time of a tool change by a tool change means, coupling a coupling member and the protective bearing, and constraining the movement of the main spindle to the front side in the axial direction. SOLUTION: When a bearing control means 41 receives a tool change start signal in a vertical machining center, the feed power to the rear stator 32 of a thrust magnetic bearing 30 is reduced, and the feed power to a front stator 35 is increased. A main spindle 3 is moved to the front side in the axial direction, and a nut 9 is brought into contact with a rear angular ball bearing 8. A tool T fitted to the main spindle 3 is extracted by the operation of a tool change means in this state, then a new tool T is fitted to the main spindle 3. Since the nut 9 screwed to the rear end section of the main spindle 3 is already kept in contact with the rear ball bearing 8, the main spindle 3 is prevented from being moved further to the front side in the axial direction, and the collision between the nut 9 and the ball bearing 8 is avoided.

Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a power amplifier stably operated in the two modes of a linear mode and a PWM(pulse width modulation) mode just by changing an input signal voltage. SOLUTION: Relating to this amplifier 1, when the input signal voltage Vin becomes higher than a certain value, the output voltage V1 of a voltage amplification stage 10 is limited to be lower than the Zener voltage of Zener diodes 12 and 13 and the base current Ib of the bipolar transistors 21 and 22 of a driver stage 20 is limited as well. As a result, a collector current Ic=hfe×1b is limited and the maximum value Vgs (max) of the gate-source voltage Vgs= Ic×Rgs (Rgs is resistance between a gate and a source) of the MOSFETs 31 and 32 of an output stage is decided. At the time, by setting the maximum value Vgs (max) of the gate-source voltage to a voltage suitable for operating the MOSFETs 31 and 32 of the output stage 30 in a saturation area, just by changing the input signal voltage, a stable operation is performed in the two modes of the linear mode and the PWM mode.

Abstract: PROBLEM TO BE SOLVED: To provide a sprue part ejector pin structure which can prevent a sprue runner from remaining in a fixed die. SOLUTION: A flange 26 is provided in the base of a sprue ejector pin 5 situated in the enter of an ejector plate 1, and the flange 26 is fitted inside a space 27 in a movable manner in relation to a die opening direction. In addition, the sprue ejector pin 5 is supported by colliding and contacting a supporting member 28 integrated with the flange 26 to the surface of a moving bottom plate 4 and by penetrating the ejector plate 1. In a position where the ejector plate 1 completes its retreat, since a clearance is formed between the rear side of the flange 26 and the bottom 30 of the ejector plate 1, even when the ejection of a gate cutting pin 7 is started by protruding an ejector rod 6, the sprue ejector pin 5 is held in the position where it ended retreat.  Therefore, even if gate cutting is performed during mold closing, a sprue runner 8 is not pushed into the fixed retainer plate 9 and thereby prevents a fixed side of the sprue runner 8 from remaining.

Filed: 1992-12-28
Abstract: PURPOSE:To simplify the manufacturing processes of a pillow and to enhance safety for human bodies by extrusion foaming a used synthetic resin into a strand, and cutting the strand into specific lengths with specific bulk density. CONSTITUTION:A used synthetic resin material collected is extrusion foamed into a strand about 0.5 to 3mm in diameter from an orifice of predetermined hole diameter in a metal die attached to an extruder and the strand is cut into about 1 to 30mm lengths to provide pellets 10 of 0.1 to 0.5g/cc bulk density for use as pillow stuffing. The synthetic resin used is polystyrene or polyethylene, etc. Azodicarbonamide is used as a foaming agent with an expansion ratio of about 1.5 to 10. The bulk density of the pellets is selected in the range of 0.1 to 0.5g/cc, since when the bulk density is above 0.5g/cc, the pillow made therefrom is too heavy to be of practical use and hard to the touch, and the pellets are then not suited for use as pillow stuffing. When the bulk density is less than 0.1g/cc, problems may arise regarding the strength of the pellets as pillow stuffing.
