Title: Hand piece for dentistry
Inventor: HIYUUBAATO OBURAADO
IPC: A61C1/14
Filed: 1990-05-25
Abstract: PURPOSE: To perform gingival or periodontal therapy by installing easily various vibration instruments to excite and concentrate a mechanical vibration around a non-rotational axis by utilizing an axial rotation. CONSTITUTION: A shaft 3 is held rotatably by an axis of a bearing 9. When a cage 4 turns with the rotation of the shaft 3, a bearing 5 is made to turn by way of an elastic stretch and bend connection member 6. Then, due to an eccentric movement, a lengthwise position 7 of a vibration axis 8 is pushed which causes the vibration axis to stagger. The vibration axis 8 has, in its middle part, three balls or globular caps 10, 11 or 12 to be push-held against a body 2 in order for its tip part to concentrate the vibration node. Accordingly, when the cage 4 rotates which pushes the lengthwise position 7, a vibration node is generated in the tip part of the vibration axis 8 as a fulcrum because the vibration axis 8 is held at three points by the balls 10, 11 & 12. This vibration force and width are transmitted forward to the direction of a head 18, and cullets 19 & 20.

Title: Two-plane polarizing laser optical system
Inventor: YAMAGUCHI AKIRA
IPC: G02B27/28
Filed: 1986-06-12
Abstract: PURPOSE:To suppress the variation of light even if the light is passed through an optical element having polarization dependency by arranging a 1/4 wavelength plate on an optical path so that the main axis forms about 45 deg. with both the two polarizing direction of a laser beam. CONSTITUTION:The 1/4 wavelength plate 3 is arranged on the optical path of laser beam so that the main axis forms about 45 deg. with both the two polarization directions of the laser beam to convert the two straight polarized components of the laser beam into circularly polarized components by the plate 3. Since the laser beam passed through the plate 3 is uniformly converted into the circularly polarized laser beam independently of the change of the polarized components of the laser beam existing before the incidence on the plate 3, a trouble varying the quantity of light is not generated even if the laser beam is passed through an optical element, e.g. a half mirror 4, having polarization dependency.

Filed: 1991-05-13
Abstract: PURPOSE:To analyze quantity of protein by adding trichloroacetic acid in the sampled urine to precipitate the protein included in the urine on the surface of a quartz oscillator, and measuring a change of the oscillation frequency of the quartz oscillator before and after the precipitation. CONSTITUTION:Trichloroacetic acid is substitute for sulfosalicylic acid to be used as the precipitant of the protein in the urine. This trichloracetic acid is reacted with globulin well beside albumin to generate the good precipitation. Consequently, total quantity of the protein in the urine is obtained accurately independently from the component of the protein in the urine. For example, a quartz oscillator is oscillated under the condition that the quartz oscillator is dipped in the mixture liquid of the BSA(cattle blood serum albumin) solution and hydglobulin solution and acid, and oscillation frequency thereof is measured. Next, 20 % sulfosalicylic acid is added in the mixture liquid to precipitate the solved protein on the surface of the quartz oscillator, and the frequency is measured to obtain a change of the oscillation frequency of the quartz oscillator before and after the precipitation. At this stage, all protein is reacted.

Title: Combustion device
Inventor: MORITA SHIGEKI
IPC: F23N5/18
Filed: 1983-07-29
Abstract: PURPOSE:To obtain a desired burner flow pattern at each burner and to reduce production of NOX without an increase in smoke dust in exhaust gas and a unburnt content in ash, by regulating a flow rate of the air fed to a secondary air feed part and a tertiary air feed part. CONSTITUTION:In case NOX reduction combustion is effected, through input of a supplement signal (b) and a boiler master signal (a) in response to such combustion, a controller 25 forces a secondary and tertiary air damper 22 to be opened in a proper opening, forces a tertiary damper 23 to be closed, forces a GM damper 24 to be slightly opened, and controls a secondary vane 21 properly. The tertiary air damper 23 is closed, and the supply of a tertiary air is disconnected and therefore, the air, passing through a secondary and tertiary common pipe 16, flows through a first branch passage 17 and is concentratedly fed to a secondary air feed pipe 14. Thus, the throat size of a burner throat 15 is made equal to a state in which it is substantially reduced in size, and velocity of flow of the air is increased. As a result, the extending-through force of a flame is ensured, and a unburnt content in ash is prevented from increasing. Further, with the GM damper 24 slightly opened, recirculating exhaust gas is fed through a second branch passage 18 by means of a tertiary air feed part, NOX is prevented from production at a flame outermost periphery zone, and ash is prevented against adhesion to the burner throat 15.

IPC: H04S1/00
Filed: 1982-08-06
Abstract: PURPOSE:To prevent the production of a peak and a dip to a frequency characteristic at a sound receiving point, by driving an auxiliary speaker with an output signal of an adder. CONSTITUTION:A synthesizer 6 synthesizes both left and right signals impressed from amplifiers 2, 3.

When an on-signal of the relay switch 4 is input from a control circuit 10, a resistance value of the input current control circuit 6 is nominally small compared with a stationary state after completion of charging a capacitor 8 in an initial state after signal input. Thus, a massive voltage can be applied to the relay coil 5 by a short time, until the stationary state is reached.
