Title: Inverter device
Inventor: IMAI TOSHIMITSU
IPC: H02M7/48
Filed: 1994-08-31
Abstract: PURPOSE:To realize the reduction of the cost of a means for detecting regenerative currents flowing through an inverter circuit while improving the accuracy of the detection of the regenerative currents. CONSTITUTION:A rectified output from a DC power circuit 2 is transmitted over an inverter circuit 1 through a smoothing choke coil 5 and a smoothing capacitor 6. A current sampling circuit 26 connected in parallel with the smoothing capacitor 6 consists of the series circuit of a capacitor 26a for detection and a resistor 26b for detection, and the terminal voltage of the resistor 26b for detection is output as a current detecting signal Vx. A regenerative current detector 27 extracts a component corresponding to regenerative currents in the inverter circuit 1 from the current detecting signal Vx, and outputs a peak value signal Vxp displaying the peak value of the regenerative currents. A regenerative-current comparison section 23b in an arithmetic processing circuit 23 outputs an oscillation-stop command signal Sa when the peak value signal Vxp exceeds a fixed value, and transmits the signal Sa over an oscillation circuit 20 in an oscillation control section 18, and stops the operation of the inverter circuit 1.

Inventor: TSUBUI OOBACHI
IPC: H01S3/131
Filed: 1990-08-07
Abstract: PURPOSE: To obtain uniform output characteristics, even if a pulse repetition rate is high by selectively attenuating the output beam of a pulse laser means, in response to a time interval between a specific pulse and a preceding pulse and maintaining the output beam at least one desired energy characteristic, regardless of the fluctuation in the time interval. CONSTITUTION: A laser control device 14 operates, so that it generates output laser beams at a pulse laser 12 in response to a pulse trigger signal from a trigger source 15. An attenuation controller 16 responds to a pulse trigger signal from the trigger source 15 and supplies an attenuation control signal to a driver 18 for attenuating equipment. The driver 18 controls the degree of attenuation of output beams due to an attenuation equipment 20, being provided along an output path 21 of the laser beams. Laser output pulses are attenuated, in response to a time interval between at least a specific pulse and a preceding pulse by the attenuating equipment 20, and a pulse energy is maintained at a desired value, regardless of the fluctuations in the time interval, thus obtaining uniform laser beam output characteristic with a high pulse repetition rate.

IPC: A61B6/03
Filed: 1988-08-24
Abstract: PURPOSE:To efficiently perform terminal communication without passing through a main CPU by reading the data for the CPU of the interruption generating source within an exclusive writing region by the interruption processing due to the CPU of an interruption command part. CONSTITUTION:An exclusive writing region A has writing regions (#0000-#5000) exclusive to CPUs 3-7. Regions #5000-#7000 are set as preparatory areas and used in the case of excessive data. In the writing region at every CPU, only own CPU is writable and other CPU is impossible to write. An interruption generation display region B is set on and after the writing region #7000 and, in the regions #7000-7010, a main CPU is set to an interruption generating source and the interruption command to other CPU is stored as the flag corresponding to the other CPU. This region B turns the flags between the CPUs in interrup tion relation ON at the time of the generation of interruption.

Title: Liquid crystal video projector device
Inventor: TANAKA EIICHI
IPC: H04N5/74
Filed: 1986-09-04
Abstract: PURPOSE:To make the boundary of dots on a crystal liquid color panel inconspicuous and to improve contrast and picture quality by providing a picture quality improvement filter, in which pattern passing by no light are formed in a matrix, close to the liquid crystal color display panel. CONSTITUTION:Light from a light source 1 becomes parallel in a capacitor lens group 2, and picture information is given through the liquid crystal color panel 3, passes by the picture quality improvement filter 4 and is projected on a screen 6 by a projection lens 5. If said lens 5 is focused on the picture quality improvement filter 4, picture elements on the liquid crystal panel 3 are out of focus slightly on the screen 6 and focused on a cross hatching on the picture quality improvement filter 4. Therefore the dots on the liquid crystal color panel become inconspicuous. The black line of the cross hatching on the picture quality improvement filter overlaps with a video, which seems to have a higher contrast visually. As a result the picture quality is improved. The picture quality improvement filter can be installed on the front or back of the liquid crystal color panel, and the pitch of the cross hatching on said filter can be smaller than those of the picture element on the liquid crystal color panel.

Title: Liquid supplier
Inventor: SHIMA TAKASHI
IPC: A47J31/00
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To discharge liquid by a predetermined volume surely. SOLUTION: When the temperature of hot water in a hot water storage tank is lower than a predetermined temperature, the hot water temperature priority control in which clear water is not supplied from a supply water cassette even if water addition is operated is executed. On every switch-on of the water addition switch, the storage volume V when next water addition is executed is calculated by subtracting the one-time discharging volume from the present storage volume in the hot water storage tank, and the water level H is calculated by dividing this by the cross-sectional area of the hot water storage tank. Then, the correction value of the opening time t of the electromagnetic valve is obtained based on the water level H. Since the water level H and the opening time t of the electromagnetic valve are in the relation of inverse proportion when the discharge volume vc is constant, the correction value f(H) is calculated so that the opening time t increases as the water level H decreases, and the opening time t of the electromagnetic valve in the next discharge is set in the correction value. When full water level is recovered in the tank, the opening time t and the storage volume V are reset to the initial values tc and V0, respectively.

Title: Method for controlling fuel in coke oven
Inventor: YOSHINO YOSHIO
IPC: C10B21/10
Filed: 1983-11-07
Abstract: PURPOSE:To obtain coke having a high strength after reaction and to shorten coking termination time, by controlling the feed rate of fuel such that ethylene concn. in gas generated from a coking chamber lies on the normal curve of ethylene concn. CONSTITUTION:Changes in the oven temp. with time well correspond to those of ethylene concn. with time. The standard pattern of changes in ethylene concn. is first set according to operation conditions such as coking cycle, initial oven temp., oven body condition, etc., coal properties such as water content, volatile matter content, particle size, etc. and the quantity of coal to be fed. Ethylene concn. in gas generated from a coking chamber is analyzed and the feed rate of fuel gas is controlled such that the measured value of the ethylene concn. lies on the standard pattern. By such a simple operation, the time of changing the feed rate of quantity of heat in programmed heating can be properly judged and the softening and melting of coal or fluidity during dry distillation can be improved. As a result, coke having a high strength after reaction can be obtd. and coking termination time can be shortened.

IPC: H02K7/116
Filed: 1992-08-05
Abstract: PURPOSE:To provide a method of manufacturing a motor with a reduction mechanism, a housing and a bracket in fewer manufacturing steps. CONSTITUTION:Through holes 58 are opened in a base 10, and the through hole has a wide opening 60 at one end opposed to a base plate 62. When the base is fixed to a mounting jig 62 with bolts 64, the whole head of the bolt is received within the wide opening 60. This prevents the bolts from interfering in machining the housing 12 and bracket. Therefore, more portions are machined simultaneously, and thus it is possible to reduce the number of steps in manufacturing a motor with a reduction mechanism.
