Title: Vacuum valve
Inventor: ISHIGAKI TSUNEO
IPC: F16K51/02
Filed: 1994-12-20
Abstract: PURPOSE: To provide a vacuum valve to be made small without any troubles brought about due to rapid exhaustion. CONSTITUTION: A flow passage switching member 45 is attached to a piston 13 for moving a valve body 11 for opening/closing a valve seat 9 provided in a flow passage 8 between a chamber port 7 and a pump port 6, by means of movement of the switching member a port 24 and a cylinder chamber 21 are switched between direct linkage via supply passages 23 and 25 and linkage via bypasses 43 and 44 and a pressure action chamber 34 in which the pressure of the chamber port 7 and atmospheric pressure are applied and a pressure adjusting valve 48 for opening/closing the bypass 43 are moved in a direction almost orthogonal to the moving direction of the piston.  When the flow passage switching member 45 operates by strokes equivalent to a specified distance, since the direction linkage of the supply passage is shut off, stopping the movement of the piston, the flow passage is made conductive by the valve body in its drawn state. When the pressure of the chamber port 7 declines, the bypass 43 is opened by the pressure adjusting valve 48, supplying compressed air into the cylinder chamber 21 and thus, the valve body 11 is fully opened.

Title: Ink jet recording head and manufacture thereof
Inventor: KIMURA SHIGERU
IPC: B41J2/055
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet recording head for preventing the decrease in the ink discharging speed upon high density and the occurrence of a crosstalk by forming a thick part separated by a thin part at each pressure chamber at a diaphragm for transmitting the vibration generated at a piezoelectric element to the pressure chamber. SOLUTION: A pressure chamber 54 is provided corresponding to a piezoelectric element 50, and the thick part 14 of a diaphragm 10 is provided corresponding to the chamber 54. When a voltage is applied to the element 50, a displacement occurs at the element 50, and is transmitted to the chamber 54 via the thick part 14 corresponding to the element 50. As a result, ink droplets are discharged from a nozzle hole 58 corresponding to the chamber 54, and hence the signal transmitted via the thick part 14 is absorbed by the thin part 12, and not transmitted to the adjacent chamber 54. The diaphragm is a flat plate, and the part 12 is the part that the diaphragm 10 is removed in a slit state.

Title: Optical head
Inventor: KIYOMOTO HIRONOBU
IPC: G11B7/135
Filed: 1992-11-20
Abstract: PURPOSE:To make the reflectance of a splitting optical system constant even when the incident angle of reflected light from a recording medium to the splitting optical system is changed by interpolating the reflectance of a reflecting film on a front surface to be changed corresponding to the incident angle of reflected light from the recording medium by using the reflecting film of a rear surface in the splitting optical system. CONSTITUTION:A remaining S-polarized light component, which is made incident at an incident angle in the range of 50-60 deg., is transmitted through a reflecting film 3a on the surface of a beam splitter BS 3 and arrives at a reflecting film 3b on the rear face. Since the film 3b is coated so that the reflectance Rs of the S polarized light component can be '1' at the incident angle 50-60 deg., the S polarized light component transmitted through the front face reflecting film 3a and made incident on the rear face reflecting film 3b is reflected there and emitted to a 1/2 wavelength board 6. Therefore, since reflectance Rp of the S polarized light component in the reflected light from a disk 1 is smaller than the reflectance Rs of the S polarized light component regardless in the BS 3 regardless of the incident angle of reflected light from the disk 1 on the BS 3, the reflected light from the disk 1 is emitted to the wavelength board while constantly amplifying the rotating angle of the polarizing plane.
