Abstract: PROBLEM TO BE SOLVED: To increase the machining efficiency by fast tool movement in a detailed shape machining. SOLUTION: After several guide dot sequences GL of tool paths for detailed part machining are generated according to contact point track dot sequences found by performing a rolling process wherein a sphere B having a radius equal to the radius of a large-diameter tool is rolled in contact with the wall surface WF and bottom surface BF of a product shape along the recessed ridge at the border between the wall surface WF and bottom surface BF, tool center position close inspection points PDP are set on the guide line dot sequences between the respective constituent points GCP of the guide line dot sequences GL and their constitution points GCP along the respective guide line dot sequences GL. Tool center positions TC are found as to those tool center position scrutiny.  When a tool path for detailed shape machining by a small-diameter tool ST is generated by connecting those tool center positions TC, the nearest point NP is found from each tool center position close inspection point PDP in each guide line dot sequence GL on the center point dot track point sequence BCL of the sphere B at the time of a rolling process. The position of the center point of the tool tip part in a spherical shape, when the small-diameter tool ST moved from each nearest point NP to the corresponding tool center position scrutiny point PDP comes into contact with the wall surface WF or bottom surface BF, is regarded as a tool center position TC.

Filed: 1989-08-21
Abstract: PURPOSE:To control electrostatic charge quantity on paper without providing a special device for removing static by providing a control means which controls output of a separating charger responding to a detected output of a surface charge potential detecting means. CONSTITUTION:Surface potential of a first piece of paper which is passed through a fixing device 8 is measured by the surface charge potential detecting means 11, and the output of an AC high voltage power source 5 is controlled so that the paper which is separated from a separating charger 6 is fed to the fixing device 8 in a state of a negative specified charge potential by the control means 12 responding to the detected output.

Abstract: PURPOSE:To prevent the deterioration of lubricating oil and ensure good lubricity, by circulating the oil, which lubricates a pair of gears constituting an oil pump, within a circulating passage connected to the oil pump, thereby cooling the oil within the circulating passage. CONSTITUTION:When an electromagnetic clutch 14 is electrified during operation of an engine E, torque of a crank shaft 12 is transferred to a driving shaft 20b, and a rotor 18b is turned to the direction C. In addition, torque of the driving shaft 20b is transferred to another driving shaft 20a via a pair of gears 19a and 19b; upper and lower. As a result, another rotor 18a is turned to the direction D. Thus, a supercharger 6 is allowed to supply the air coming from an inlet port 21 to an outlet side 22, without compressing the air, for supercharging. In this case, the gear 19b turns to the direction B, while the gear 19a turns in the direction A, thereby operating an oil pump 23. Therefore, the oil, which is taken in from an intake 24, is sent by pressure to the outlet port side 25. As a result, the oil in the tank 27 circulates in a circulating passage 26 and supplied to the oil pump 23 via an oil cooler 29.

Abstract: PURPOSE:To produce glass beads having uniform particle size, and excellent roundness, breakage stength, etc., by cutting a freely falling molten glass stream having a specific viscosity with a fixed edge and a movable edge, and making the obtained glass particle to a spherical form taking advantage of the surface tension.

Filed: 1989-08-19
Abstract: PURPOSE:To reduce an amount of using air or gas with high reliability obtained in pump action by actuating a pilot rod simultaneously with action of a solenoid valve so as to move air or gas alternately to a pair of air chambers. CONSTITUTION:For time t1, because diaphragm valves D1, D2 are moved to left from a neutral point, a high pressure is generated in an air chamber 2A with a low pressure generated in a chamber 2B. Consequently, solenoid valves 1, 4 are closed with 2, 3 opened, and air or gas is transferred to the chamber 2A from 2B by a pilot rod 12. While for time t2, because the valves D1, D2 are moved to the neutral point from the left, the chamber 2A is placed in low pressure with 28 in high pressure. Consequently, air or gas is moved to the chamber 28 from 2A by a rod 13 with the solenoid valves 1 to 4 left as closed. While for time t3, because the valves D1, D2 are moved to right from the neutral point, the chamber 2A obtains low pressure with 2B further in high pressure. Consequently, the solenoid valves 2, 3 are closed with 1, 4 opened, and air or gas is moved to the chamber 2B from 2A by the rod 13. While for time t4, because the valves D1, D2 are moved to the neutral point from the right, the chamber 2A obtains high pressure with 2B low pressure, and the air or the like is moved to the chamber 2A from 2B.

Title: Phase locked loop
Inventor: YOSHIDA ATSUSHI
IPC: H03L7/10
Filed: 1984-10-12
Abstract: PURPOSE:To reduce the time required for pull-in by providing a variable frequency divider, making its frequency dividing ratio variable at pull-in and fixing it at steady-state. CONSTITUTION:A variable frequency divider 8 is inserted between a voltage controlled oscillator 7 and a phase comparator circuit 5. The frequency ratio of the variable frequency divider 8 is changed depending on the output of a loop filter 6 at pull-in and fixed to a prescribed frequency dividing ratio at steady-state after the end of pull-in. Since the frequency dividing ratio of the frequency divider 8 is changed in such a way, even when the change in the oscillating frequency of the oscillator 7 is narrow, the apparent frequency changing range is expanded. That is, the apparent oscillated frequency is increased by decreasing the frequency dividing ratio and the apparent oscillated frequency is lowered by increasing the frequency dividing ratio. Thus, the time required for pull-in is reduced.

Abstract: PURPOSE:To prevent a photosensitive body from rotating irregularly even if its load varies by coupling one of two worms engaging a worm wheel with a driving shaft through a spring and also energizing it in the rotating direction of the driving shaft. CONSTITUTION:A worm engaging the worm wheel 3 coupled directly with the rotating shaft of a photosensitive body is divided into 1st and 2nd worms 4 and 5 and one end of the spring 12 inserted into the groove 10b of a support member 10 fixed on the shaft 7 is fixed to the worm 5, which is energized in the rotating direction of the shaft 7. The worm 4 is fixed on the shaft 7, the worm 5 is supported rotatably through a bearing 9, and the shaft 7 is rotated to drive the wheel 3 by the spring 12 without any play originating from the engagement with the wheel 3 and worms. Therefore, even if the photosensitive body varies in load or is shocked externally, the irregularity in rotation is eliminated and an image which is neither distorted nor shifts in position is formed.
