Title: Shape of vane groove of rotor for vane pump
Inventor: TAKEUCHI YOSHINORI
IPC: F04C2/344
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To attenuate stress concentration on a vane groove and prevent a fatigue failure of a rotor for a vane pump by forming the cross-sectional shape of the vane groove in the rotor in a direction perpendicular to a rotor shaft into an ellipse which is longer in a sliding direction of a vane, wherein the maximum width is greater than the width of the vane. SOLUTION: In a vane groove 4, the cross-sectional shape in a direction perpendicular to a rotor shaft is an ellipse which is longer in a sliding direction of a vane 5. A maximum bending stress is generated at a point (e) having a relatively great change of a cross-sectional shape and being located between a point (d) and a point (b) at the tips of the vane groove 4 and considerably near the point (s). Since the point (e) is one point on the wall face of the center of the ellipse of the vane groove 4 formed into an ellipse which is longer in the sliding direction of the vane 5, the change in cross-sectional shape is gradual in comparison with a conventional circular groove. Stress concentration on the point (e) can be attenuated accordingly and a stress value is reduced, thereby preventing a fatigue failure of a rotor 1.

Title: Microphone
Inventor: ISHIZAKI KATSUYA
IPC: H04R23/00
Filed: 1982-03-14
Abstract: PURPOSE:To obtain a microphone of a large output and less distortion by detecting the displacement of a diaphragm digitally and accurately. CONSTITUTION:The titled microphone consists of a diaphragm 1, a half mirror 3, a laser light irradiator L, and a photodetector P. The reflected light comes from the diaphragm 1 and the mirror 2 to the element P and either dark or bright part is obtained through interference. Whe the diaphragm 1 is displaced, since the change in dark and bright parts is given to the element P at each wavelength of light, the movement of the diaphragm is known by counting the change. In this case, to detect the distinction of front and rear parts of the diaphragm 1, a conductor is fitted to the diaphragm like a velocity type microphone as a pattern and placed in a magnetic field, and the discrimination is executed depending on the polarity of the electromagnetic force. Further, the discrimination is executed through the increase/decrease in an electrostatic induction voltage of a high frequency by using the change in the static capacitance between the diaphragm 1 and other fixed electrode.

Abstract: PURPOSE:To make accurately dialing to an opposite party of a received dial special number by adding an external line dial specific number to a caller number representing a received opposite party number. CONSTITUTION:When a setup message is sent from an integrated services digital network ISDN 101 to a PBX 103 and a controller CC 108 receives an incoming call notice, an incoming extension destination is decided. When a caller number information element is included in the setup message, the CC 108 references a dial default storage table in the CC 108 and when the dialing default is an extension, an external line dial special number '0' is added to the caller number. Then the CC 108 reaches a call to the extension terminal 104. When the called party is dialed from the terminal 104 after the end of speech and the operator makes incoming call redialing, the terminal 104 reads the destination dialing number received before from a memory and makes dialing. Thus, even when a dialing default of the terminal 104 is an external line or an extension, the dialing is implemented with a simple incoming rediating.
