Title: Laser device
Inventor: ISHIBASHI NOBUHIKO
IPC: H01S3/30
Filed: 1988-04-30
Abstract: PURPOSE:To obtain laser rays rich in color with a single laser source by a method wherein laser rays of frequencies omega1 and omega2 are made concurrently and coaxially incident on a material which induces a Raman effect. CONSTITUTION:Laser rays 5 and 6 emitted from dye laser sources 1 and 2 are made a streak of laser rays 7 through a half mirror 3 and incident on a central axis of a Raman cell 4 concurrently. The incident laser rays of frequencies omega1 and omega2 generate standard Raman light rays whose frequencies are represented by equations, omegas1=omega1+ or -momegasr and omegas2=omega2+ or -momegasr, respectively, through the action of a Raman medium, and at the same time layer rays (two colors induced Raman light) of a frequency omega, which is related to the frequency difference between omega1 and omega2 and represented by an equation, omega=(omega1+ or -momegasr)+ or -n(omega1-omega2), appear in large numbers (regarding an integer n). By these processes, output rays 8 possessed of a large number of spectral lines can be obtained from the Raman cell 4, so that the rays 8 are separated by a prism 9 into a large number of laser rays 10 which glisten in all the color of the rainbow.

Title: Combustion method for crematory
Inventor: KAWAKAMI TAKASHI
IPC: F23G1/00
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To perform efficient combustion of the remains to be cremated by a method wherein a fuel feed amount and an air feed amount to a burner are controlled, based on the temperature change rate of a furnace temperature measured by a furnace temperature sensor. SOLUTION: Furnace temperature sensors 53 and 54 are arranged at combustion chambers 1 and 2, fuel feed amounts and air feed amounts to burners 41 and 42 are controlled, based on the temperature change rate of furnace temperatures measured by the furnace temperature sensors 53 and 54. Thus, at the initial stage of combustion, when a temperature increase rate is high due to self-combustion of a combustible physical properties substance, the feed of fuel is suppressed and when a temperature increase rate is low due to deficiency in ignition of the combustible physical properties substance, a fuel feed amount is increased to perform efficient fuel feed. Further, when temperature exceeds a given value, it is decided that self-combustion is continued even when a temperature increase rate is low, the feed of fuel is suppressed.  At the latter stage of combustion, when a furnace temperature is reduced to a value lower than a given value, a furnace pressure is increased through control of exhaust gas, incurring of a heat loss is suppressed by prevention of lowering of a furnace temperature, and a fuel consumption rate is decreased.

Title: Liquid crystal display panel and production thereof
Inventor: TANUMA SEIJI
IPC: G02F1/133
Filed: 1988-04-29
Abstract: PURPOSE:To less steepen the change in transmittance with an impressed voltage by providing an oriented film contg. a photoreactive material on at least one of the transparent electrodes of 1st and 2nd insulating substrates. CONSTITUTION:The oriented film 3 contg. the photoreactive material is provided on the transparent electrode 2 of the substrate 1 to form picture elements and the orientation control power is partially changed by the partial light irradiation applied within one picture element. The threshold voltage and voltage- transmittance characteristics as the electro-optic characteristics of the ferroelctric liquid crystal panel vary sensitively with the kind of the oriented film and the surface condition of the oriented film such as rubbing method. The photoreactive material is, therefore, changed in the stereoscopic structure if the oriented film 3 contg. the photoreactive material is subjected to the partial light irradiation after the uniform control power of the oriented film is once formed by subjecting the film to a rubbing treatment. The orientation control power, therefore, changes. The electrooptic characteristics over the entire part are thereby made into the synthesized characteristics of both thereof and, therefore, the gentle rising characteristic is obtd.

Title: Method and device for generating variable frequency by using direct digital synthesizer
Inventor: BIZEN NAOTO
IPC: G11B19/28
Filed: 1995-04-10
Abstract: PURPOSE: To stabilize multi-step output frequency without complicating circuit configuration by using a direct digital synthesizer. CONSTITUTION: In the case of setting recording density to (n+1) by gradually increasing command frequency Fh(n) proportional to rotational frequency when the number of scanning lines in one rotation is (n), when the number of steps is an integer of (m), command frequency Fh1 becomes Fh1=Mn.Fh(n)/m(n+1). In order to realize the equation, a pulse with the frequency of mn.Fh(n) is generated from a clock generation part 1 for fixing the period of operation of a phase addition part 3 by a clock output c1 with a certain fixed frequency and a coefficient value (nm+j) is set up in a period setting part 2 for setting bb proportional to the period o a required output pulse. Thereby the necessity of a pulse removing circuit for removing a pulse with a large frequency division having a small frequency step can be obtained by a simple circuit mechanism.

Title: Fusion joint method
Inventor: IWASAKI MASAYA
IPC: B29C65/34
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent shortage of melting of resin and shortage of strength from generating by raising voltage so as to return current to the state before falling, when short circuit is dissolved and resistance is increased. SOLUTION: Current is begun to be carried to a joint 1 in a state of fixing voltage by a voltage adjusting means 2. Then resistance is gradually increased accompanying temperature rise of a heating wire. When short circuit is generated during the gradual increase of resistance, the resistance value is reduced, and current measured by a current measuring means 3 is increased. When current changing rate per unit time exceeds the threshold value, a control means 4 feedback controls the voltage adjusting means 2. Hence, voltage is lowered so as to return current to the level before rising. When the second short circuit is generated, similar control is carried out.  When short of one place in two places shorted is dissolved, resistance is increased by the portion, current is decreased, and when the current changing rate exceeds the threshold value, similarly the voltage adjusting means is feedback controlled, so as to return current to the level before falling.

Title: Measurement of impurity distribution in semiconductor
Inventor: MORIKAWA HIROSHI
IPC: H01L21/66
Filed: 1982-06-24
Abstract: PURPOSE:To obtain impurity distribution during the anode oxidation with a constant current by executing the anode oxidation of semiconductor wafer with a constant DC and by measuring change of voltage across such DC source. CONSTITUTION:A wafer 1 is oxidized from the surface through the anode oxidation while a single surface, for example, the rear surface of semiconductor wafer 1 is not separated from the electrolyte. An externally applied voltage is equal to a sum of a voltage drop at the oxide film formed and a voltage drop at the semiconductor and a voltage drop of semiconductor is equal to a withstand voltage of semiconductor wafer under such condition. A withstand voltage of semiconductor wafer in the thickness direction is determined by distribution of impurity in such a direction but depends on electrode area. Therefore, when distribution of impurity from the surface to the end of depletion layer at the time of breakdown is known, distribution of impurity up the deeper area than the depletion layer end can be obtained by measuring voltage change through anode oxidation with a constant current.
