Title: Machining method using ball end mill
Inventor: KUWABARA HARUYOSHI
IPC: B23C3/00
Filed: 1990-11-16
Abstract: PURPOSE:To greatly enhance the surface-roughness with elimination of conical uncut parts on a workpiece by optimally setting the feed speed and rotational speed of a ball end mill, the lengths, and number of linear cutting blades formed at the forward end of the mill, and the intervals of repetitions of feed. CONSTITUTION:A ball end mill 26 is formed thereon with arcuated cutting blades 24, 25 with which the circular loci around the rotary axis 21 depict a substantially spherical surface, and a linear cutting blade 22 which is formed forward of the arcuated cutting edges 24, 25 and with which the circular loci about the rotary center axis 21 depict a substantially flat vertical surface. During machining the outer surface of a workpiece with the use of this ball end mill 26, repetitions of feeds relative to the ball end mill 26 are applied to the workpiece. In association with the movement of the ball end mill 26, relative to the workpiece, the feed speed, rotational speed and intervals of repetitions of feeds of the ball end mill are set so as to reduce uncut parts each produced at every revolution of the ball end mill.

Title: Vane pump
Inventor: YABE CHIAKI
IPC: F04C2/344
Filed: 1987-12-07
Abstract: PURPOSE:To reduce pulsation of delivery hydraulic pressure by forming notches in a rotor and a plate member contactable therewith then communicating the notches synchronously with pulsation of delivery pressure oil and recirculating a portion of the delivery oil to tank side. CONSTITUTION:A notch 34 communicated with respective vane backface chambers 32 is formed in a face of a rotor 12 rotatable integrally with a drive shaft 10 which contacts with a rear body (plate member) 4, while a notch 38 communicated with a spill port 36 of the drive shaft 10 is formed in the face of the plate member 4. When a vane pump is constructed such that the vane backface chamber 32 communicates with the spill port 36 when the rotor 12 rotates to overlap the notches 34, 38 each other and the timing thereof is matched with the peak of pulsating delivery oil pressure, the vane backface chamber 32 where delivery oil is led in communicates with the spill port 36 so as to leak the delivery oil slightly and recirculate the leaked oil to tank side. Since the quantity of leaked oil may be quite small, pulsation of delivery pressure oil can be reduced without exerting influence onto the pump performance, resulting in reduction of noise.

Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To perform normal reception even if a dynamic range of receiving part of a slave station is narrow and to construct an inexpensive system by adjusting an optical signal transmitting level outputted from a master station at each slave station and making optical signal receiving levels in each slave station that has different transmission loss respectively constant. SOLUTION: Communication between a master station and each slave station uses an optical burst signal. The station A receives the optical burst signal from a slave station Bn at an 0/E part 3A, converts it into an electric signal and sends it to a TDMA receiving part 4A. A level information detecting part 8A detects information of an optical receiving level that is notified from the station Bn from a signal that is sent to the part 4A and notifies the degree of power deterioration due to transmission loss to an optical transmission level controlling part 9A. The part 9A operates a variable ATT 7A which should adjust an optical transmission level to each slave station based on the information and performs control so that an optical receiving level at the station Bn may be an appropriate level.

Title: Measurement of hydrogen in thin film
Inventor: TANAKA MASAKO
IPC: G01N23/20
Filed: 1988-12-08
Abstract: PURPOSE:To achieve a higher measuring accuracy by specifying energy and an angle of incidence of charged particles incident on a thin film made of amorphous carbon or the like. CONSTITUTION:Charged particles radiated at a slit 1 are made incident on a thin film 2 at such a small angle that atom C and atom H bounce by an elastic scattering thereof. The atom C fails to reach a detector 3 losing energy with a Mylar filter 4 and hence, the atom H alone reaches the detector 3. So, energy of the atom H is analyzed with the detector 3 to measure an electric charge of the atom H in terms of energy. Then, an energy spectrum is determined as indicating a relationship between the energy of the atom H and an energy-wise number of the atom H to measure a depth-wise distribution of the atom H in the thin film 2 and an absolute amount of the atom H based thereon. Here, the energy of charged particles and the angle of incidence are set at 6-8 Mev and 6-10 deg. respectively. This is because a higher measuring accuracy is attained with small depth-wise resolutions at 6 MeV in energy while the atom H fails to bounce below the value. The atom H also fails to bounce below 6 deg. in angle of incidence.

Abstract: PURPOSE:To prevent the degradation in contrast by adsorption of moisture, etc., and to improve silylation efficiency by executing a treatment for patterning and exposing a resist film and a treatment for exposing the resist film to an org. compd. in a hermetic system to form an org. film pattern. CONSTITUTION:The resist film 22 is formed atop the subsurface 21 of a substrate and the treatment for patterning and exposing the resist film 22 and the treatment for exposing the same to the org. metal compd. are executed in the hermetic system to induce the selective reaction by exposing by which the org. film pattern is formed. The org. film pattern is then developed by anisotropic etching. Namely, the treatment for patterning and exposing the resist film 22 formed atop the subsurface 21 of the substrate and the treatment for exposing the same to the org. metal compd. are executed in the hermetic system and, therefore, the adsorption of moisture is obviated and the degradation in the contrast is prevented. The simplification of the stage by integrating the treatments for patterning and exposing and exposing the film to the org. metal compd. to one device is enabled. In addition, the silylation efficiency is improved by utilizing the exposing energy as the silylation energy as it is.
