Filed: 1987-10-02
Abstract: PURPOSE:To make constant the scanning speed of light from a light source without generating the change of scanning position to be caused by the wrong fitting of a deflector or the error of shape, and to satisfactorily form the image of light from a light source on a medium to be scanned by making the shape of aspheric surface of a ftheta lens satisfy a specific condition. CONSTITUTION:A 2nd image forming optical system arranged between the deflector 6 and the medium to be scanned 4 is composed of a single lens 71 possessing aspheric surfaces and a single lens 72 possessing toric surfaces. The shapes of the lenses 71 and 72 meet the equation I in terms of coordinate system such as axes (x), (y) and (z), which orthogonally intersect with one another. With respect of equations h=sq. rt. y<2>+z<2> and c=1/r0, r0 represents the curvature radius of a nearer axis; (k), a coefficient of the aspheric surface; as, a constant. Where (n) is a refraction factor, 1.6X10<-2nk/r0<1.7X10<-2> holds. Thus, the scanning position never changes in spite of the fitting error of the deflector and the error of shape. In addition, the image of light from a light source can be formed satisfactorily on the medium to be scanned.

Title: Step motor controller and control method
Inventor: IMAGAWA KAZUHIKO
IPC: H02P8/00
Filed: 1990-09-21
Abstract: PURPOSE:To suppress vibration and to realize smooth low speed operation by increasing or decreasing the driving voltage of a step motor in correspondence to the increase or decrease of the frequency of input pulse signal. CONSTITUTION:A switching circuit 14 applies a predetermined driving voltage V onto predetermined coils sequentially based on a phase signal d. The driving voltage V is increased or decreased according to the increase or decrease of the frequency of an input pulse signal (a). Frequency of the input pulse signal (a) is increased or decreased in correspondence with the increase or decrease of a rotational speed command. In other words, frequency of the input pulse signal (a) decreases as the motor speed decreases. Consequently, the driving voltage V of motor decreases thus suppressing variation of exciting current per unit time. As a result, variation of the rotational speed during a single step angle is suppressed at the time of low speed operation thus suppressing pulsation when compared with constant current exciting system resulting in suppression of vibration.

Filed: 1988-10-04
Abstract: PURPOSE:To insure high sealing performance by forming a stopper so that it has a check valve formed between its outer periphery and the inner periphery of a cylinder and arranged in an oil passage connecting a negative pressure chamber and a rod-side oil chamber. CONSTITUTION:When a stay damper approaches an extended condition, the head of a collar part 8 enters the inner periphery of a body part 40. Working oil in a negative pressure chamber R thus flows out through a check valve C consisting of an oil passage L and a lip seal 20 to a rod-side oil chamber A side. Further, when a piston rod 2 is moved further in the direction of extension, and the extended condition is reached, a valve stopper 32 is abutted on the end face 40b, and further extension is blocked. When the stay damper is compressed from the extended condition by the action of external force, the oil passage L is closed by the action of the check valve C, flowing-in of the working oil into the negative pressure chamber R is blocked, and the extended condition of the stay damper is maintained.

Abstract: PURPOSE:To ensure low cost in the manufacture of piping having high heat and liquid leakage resistance by constituting a main cooling tube and a branch tube so led from the main cooling tube as to correspond to each cooling plate with an electrical insulation material having high heat and corrosion resistance. CONSTITUTION:A main cooling tube 4 and a branch tube 4 are made of an electrical insulation material including PEEK (polyether ether ketone), fluorinated hydrocarbon resin or ceramics. Cooling water enters the main cooling tube 4 via the conduit 11 of an outer pipe line, and is, then, separated to flow in a cooling tube 2a buried in each cooling plate 2 via a branch tube 4a, a connection tube 12 and a header tube 3. In this case, the main cooling tube 4 and branch tube 4a are constituted with an insulator and, therefore, electrical insulation is maintained between each cooling plate 2, and between the conduit 11 of the outer pipe line having grounding potential and the cooling plate 2. Also, as a bend section 12a is formed at the connection tube 12, thermal stress generated during operation is absorbed by the aforesaid bend section 12a.

Abstract: PURPOSE:To form efficiently a thin film with an uniform thickness, by providing with a tube shaped reaction chamber having a planar section made of quartz glass, and by constituting a light source by line shaped lamps being arrayed in parallel to each other outside the planar section. CONSTITUTION:Reaction gas 7 introduced into the quartz glass tube 21 is excited and decomposed by light emitted from a light source 12, and the resulted reaction products are deposited on a substrate 4 to form a thin film thereon. In this case, line shaped lamps 12a are arrayed outside the upper planar section 21a of the quartz glass tube 21. Accordingly, the distance from the substrate 4 to the lamps becomes nearer so that illumination on the substrate 4 can be increased. Moreover, since the section of the quartz glass tube 21 over which the lamps 21a are being arrayed is planar, the lamps 12a can be positioned in a plane being parallel to the substrate 4 to result in an uniform illumination on the substrate 4, so that an uniform thickness thin film can be efficiently formed.

Abstract: PURPOSE: To prevent uneven abrasion and unstable behavior of a sealing member so as to improve durability and compression performance of the sealing member. CONSTITUTION: A notch 22 approximately parallel to side faces 5B, 5C of a recessed groove 5 and extending in the length direction of a sealing member at a fixed length is formed in the tip side of the sealing member so that the tip side of the sealing member is divided into two, an internal circumferential sealing part 23 and an outer circumferential sealing part 24. Therefore these sealing parts 23, 24 are elastically deformed independently each other so that curvature difference between the inside faces 23C, 24C and the outside faces 23D, 24D is reduced. As a result, bending rigidity of these sealing parts can be effectively reduced so that the sealing parts 23, 24 can be smoothly and elastically deformed along the curvature of a lap part 3 and one sides of the upper side faces 23B, 24B can be prevented from abutting on a tooth bottom side 8A in the opposite side respectively.

Title: Microprocessor
Inventor: SUGIMOTO MOTOAKI
IPC: G06F15/00
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent a meaningless error from being produced by providing a 1st and a 2nd storage means, a selecting means which selects an instruction code, etc., which is stored in the 1st storage means and sends it to the 2nd storage means and a state controlling means that directly outputs the instruction code, etc., which is stored in the 1st storage means to the 1st storage means. SOLUTION: A branching and undefined instruction detecting part 8 confirms that a branch condition signal from an instruction detecting part 3 does not accomplish a branch condition at an L and makes a branch accomplishment signal U the L. When the signal U becomes the L, a state controlling part 18 passes an error instruction of an IRG 16 to the part 3 and makes an IRG effective signal M the L. A fetch address selection controlling part 13 writes an error vector that shows an address of prescribed error processing to an FPC 12 and shifts to error processing. Thus, because the fetch operation of an instruction code and the execution operation of an instruction are separately and independently performed, a fetch system can be separated from an execution system.  Therefore, the continuous execution of instructions becomes possible and also the production of a meaningless error can be prevented.
