Title: Piston pump
Inventor: OKUBO YOSHIO
IPC: F04B9/107
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To transmit pressure-increasing action in a first actuation chamber to a second actuation chamber without using bellows by reciprocating a plunger in a cylinder bore for increasing/decreasing pressure in the second actuation chamber, and moving a piston to advance to/retract from the first actuation chamber in accordance with pressure increase and decrease for opening/closing a discharge valve and an inlet valve. SOLUTION: A plunger 32 is moved by rotation of a drive shaft 38 through an eccentric cam 37 and a sheet cam 40 to a second actuation chamber 5 against a coil spring. A communication hole 34 is then closed on an inner circumferential surface of a cylinder bore 31, and as the plunger 32 is moved, inner pressure of the second actuation chamber 5 is increased to move a piston 19 to slide to a first actuation chamber 4. Pressure in the first actuation chamber 4 is thus increased to open a discharge valve 12. As the drive shaft 38 is further rotated, the plunger 32 is retracted from the second actuation chamber by force of the spring 35 to decrease inner pressure of the second actuation chamber 5, so the piston 19 returns to an initial position by a spring 26. A discharge valve 26 is closed, and an inlet valve 6 is opened to be ready for next discharge.  Pressure increase of the first actuation chamber 4 is thus transmitted to the second actuation chamber 5.

Title: Solid state laser rod
Inventor: SHIRAKI KENICHI
IPC: H01S3/16
Filed: 1980-03-26
Abstract: PURPOSE:To obtain the highly efficient laser output by providing a layer including Ce in a rod containing Nd as active ions and shielding the short wavelenth light from an exciting lamp. CONSTITUTION:Materials for the solid state laser such as Nd:YAG, Nd:YAlO3, and the like, with Nd as the active ions, have excellent light emitting efficiency and excellent optical quality, but are prone to be subjected to the effect of the  ultraviolet light or the visible light of 5,000Angstrom  or less. For example, if an Xe lamp is  used for excitation, the laser oscillating efficiency is lowered by the low wavelength  light of 5,000Angstrom  or less. For example, if GdGa garnet crystal containing Ce is grown  in the vicinity of the material of Nd:GGG by the liquid phase or gasoues phase  epitaxial growth, said harmful short wavelength light can be shielded, and the highly efficient laser output in the structure simpler than the conventional color  filter devices can be obtained. There is no trouble evn though Ce is added to the  inside of the rod.

Title: Production of silicon single crystal
Inventor: TAKANO KIYOTAKA
IPC: C30B15/00
Filed: 1992-01-30
Abstract: PURPOSE:To prevent the splash of molten silicon and the formation of polycrystalline phase by using a granular silicon having a specific residual hydrogen concentration as a polycrystalline raw material. CONSTITUTION:A silicon single crystal is produced by pulling up the single crystal while continuously supplying at least a proper amount of a polycrystalline raw material simultaneously with the growth of the single crystal. In the above process, a granular silicon having a residual hydrogen concentration (x) of 10ppm.wt.<x<100ppm.wt. is used as the raw material. The blowing of hydrogen gas is suppressed by the use of the raw material to suppress the splash of molten silicon even if the molten silicon is instantaneously exposed to an ultra-high temperature (the melting point of silicon, i.e., 1420 deg.C) in the course of falling. Furthermore, since the raw material is free from dehydrogenation treatment, it is relatively quickly dissolved after being fallen into the molten silicon to prevent the formation of a polycrystalline phase caused by the prolonged dissolution time. Accordingly, the success ratio of continuous charge is remarkably improved. The continuous charge is especially important because the feeding rate of the raw material has to be increased by the weight increase of the crystal in the case of producing a crystal having large diameter.
