Title: Charged beam lithography
Inventor: KOYAMA KIYOMI
IPC: H01L21/027
Filed: 1988-03-31
Abstract: PURPOSE:To prevent graphic processing throughput from reducing by dividing a part of a graphic to be depicted into shot data in advance and thereby forming the graphic with divided shot data and nondivided shot data. CONSTITUTION:Graphic patterns other than rectangles are divided into shot data in advance. Graphic data is transmitted from a computer to a graphic depicting circuit 10 and data for rectangles (1)-(3) are identified as nondivided shot data in a graphic code identifying circuit 12 and are fed to a deflection control circuit 20. The graphic patterns other than rectangles (4)-13 are identified as divided shot data and directly fed to the deflection control circuit 20. Since the graphic is processed on a divided shot data basis, it is only the rectangular patterns that a shot dividing circuit 13 must divide. This method disengages the graphic processing throughput from the shot data dividing speed, thereby improving the graphic processing speed.

Title: Endoscope device
Inventor: KISHI YUKITOSHI
IPC: G02B6/42
Filed: 1981-05-25
Abstract: PURPOSE:To recover optical transmittivity by directly transmitting light from a light source to an optical fiber flux for image guide of which optical transmittivity is deteriorated by coloration due to irradiation through an optical fiber flux for light guide. CONSTITUTION:A leading end part of an image forming optical system 12 of an endoscope body 1 is connected to an eyepiece optical system 14 of the endoscope through an optical connection apparatus. Consequently, light from a light source for observation is directly transmitted from a leading end 11b of an optical fiber flux 11 for light guide to an end part 13b in the eyepiece optical system side of an optical glass fiber flux 13 for image guide. Thus, the optical fiber flux 13 colored (yellowed) by irradiation recovers its optical transmittivity up to 89% within 10hrs by using light from an 150W halogen light source for example.

IPC: H02M7/48
Filed: 1993-04-07
Abstract: PURPOSE:To economically compute an output voltage without using an insulated amplifier by computing an error voltage from a waste time, PWM carrier frequency and an DC voltage of a DC power to be supplied to a voltage type PWM inverter and correcting a conduction ratio using the error voltage as a correction amount after the error voltage is caused to change in proportion to a power factor of the output. CONSTITUTION:In a vector controlled PWM inverter, a power factor is obtained in arithmetic circuits 1, 2 from a torque current command Ij and an excitation current command IM and an amount of compensation is obtained by multiplying the power factor with an error voltage reference amounmt Verr in the arithmetic circuit 3. Here, the error voltage reference amount Verr has a duration of the waste time and an amplitude of the DC voltage and should be equal to the value obtained by averaging the error voltage generated for each switching with the carrier frequency. Next, the amount of compensation is subtracted from the conduction ratio lambda* of the inverter in the arithmetic circuit 4, the lambda-V conversion is carried out in the arithmetic circuit 5 and the result is added with the DC voltage VDC to output an output voltage Vist.

Abstract: PURPOSE:To simplify the data compression by converting a sampled input picture data at each picture into a code representing a dot pattern decided at each coordinate in a threshold matrix. CONSTITUTION:A coder is formed by counters 21, 22 and an ROM23. The counter 21 counts a picture element clock up to the horizontal size of the threshold matrix in the ROM23 and is reset by a horizontal synchronizing signal Hsync.

An output signal of the counters 21, 22 gives coordinates of row and column in the threshold matrix stored in the ROM23. This coordinate position signal and a 8-bit picture data (a) in an input device are inputted to the ROM23, from which a 4-bit code C is outputted. Then, the data is compressed with simple constitution.

IPC: H01M10/39
Filed: 1988-03-31
Abstract: PURPOSE:To improve the energy efficiency of a battery by constructing a cathode conductive material of inner and outer layers, and orientating the conductive fiber of each layer in a specified direction. CONSTITUTION:A cathode conductive material M formed with a carbon fiber of mat and cylinder shape is formed in two layers of a conductive layer Ma for an outside cathode and a conductive layer Mb for an inner cathode. The ratio of fiber oriented in the longitudinal direction of a cathode vessel 2, in the carbon fiber of the layer Ma, is set to be 80%. As a result, when electrons moving to the inner peripheral face of the vessel 2 along the fiber of the layer Mb at the time of charging of battery enter into the layer Ma, the electrons are deflected in the vertical direction until the electrons are brought into contact with the inner peripheral face of the vessel 2 since the fiber direction is set to be the longitudinal direction. The electrons further moves to the inner peripheral face smoothly and converged into a cathode terminal 1 smoothly, thereby the energy efficiency of battery is improved. The ratio of fiber of the layer Mb oriented in the radial direction of the vessel 2 is set to be 30% or more, the electrtons moved to the layer Mb from a solid electrolytic tube 5 moves to the layer Ma speedily, and the flow of the electrons is facilitated, so the energy efficiency of battery is further improved.

IPC: B23Q15/013
Filed: 1989-03-30
Abstract: PURPOSE:To prevent the setting of the finishing dimension from being obstructed, by constituting thew title device so that when the second signal is outputted from a position detecting means before a work is shifted, the shift starting position for the work is returned to the second shift starting point on the opposite side to the shift direction by a control means and then carrying out feed control again. CONSTITUTION:When a workpiece W is set, and a work position detecting means 23 outputs the second signal 11 abruptly or simultaneously with the first signal I at the shift starting position N for the work W, a controller 24 judges said output, and the right edge surface F3 of the work W is returned to the second shift starting the position P which is set by the slight return from the shift starting position N by reversely revolving a control motor 14. At this time, also a center member 9 is shifted, following a center member 8. When the detector 23 confirms the return to a position slightly before the C position or B position, from the signal, normal control is executed by revolving the motor 14 again. Therefore, the excessive cut for the right edge surface F3 is prevented.
