Title: Zoom lens with large diameter
Inventor: YAMAMOTO MICHIKO
IPC: G02B15/167
Filed: 1991-04-12
Abstract: PURPOSE:To obtain a compact and bright zoom lens with a large diameter by using an aspherical lens. CONSTITUTION:The large diameter zoom lens is a zooming lens for executing zooming by successively arranging a 1st positive lens group, a 2nd negative lens group, a 3rd negative lens group, and a 4th positive lens group from an object side and moving the 2nd and 3rd lens groups. A lens R6 in the 2nd lens group and a lens R20 in the 4th lens group have aspherical faces. A lens R2 in the 1st lens group, a lens R9 in the 2nd lens group and a lens R23 in the 4th lens group are provided with combined faces. Respective aberrations of the lenses are satisfied as lenses for a video camera. Since the 1st lens group includes no aspherical lens, the diameter can be comparatively reduced and the cost can also be reduced.

Abstract: PURPOSE:To decrease an electromagnetic disturbing wave from a power supply bus by providing an LC filter circuit consisting of an inductance and a capacitor, which supplies electric power to respective driving ICs, nearby the respective driving ICs. CONSTITUTION:A signal generating circuit 1 generates a signal group required to drive the driving ICs 2 and 3 and sends it out to the driving ICs 2 and 3 through a signal group 4. A power source 5 supplies electric power to the driving ICs 2 and 3 from the power source bus through the LC filter 7. The driving IC 2 is connected to the column electrode group 9 of a display unit 8 and the driving IC 3 is connected to the row electrode group 10 of the display unit 8; and the intersections of the electrode groups are made to illuminate, thereby obtaining desired display information on the display unit 8. Here, the currents of the driving ICs 2 and 3 are absorbed by the LC filter 7 and no pulse current due to the switching of the driving ICs 2 and 3 never flows to the power source bus as it is.

Title: Ink jet recording head
Inventor: YASUTOMI HIDEO
IPC: B41J2/055
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To decrease occupation width in the main scanning direction by inclining the arranging direction of nozzle against the arranging direction of ink channel thereby reducing the driving power of a driver and increasing the density in the subscanning direction. SOLUTION: An ink jet recording head 20 comprises a large diameter ink droplet jetting head part 21, and a small diameter ink droplet jetting head part 22. The arranging direction D1 of large diameter nozzle 31 at the large diameter head part 21 is inclined by an angle θ1 against the main scanning direction X and the subscanning direction Y and the angle θ1 is set at 30 deg.. Similarly, the arranging direction D2 of small diameter nozzle 32 at the small diameter head part 22 is inclined by an angle θ1=30 deg.. Since the pitch p1 of the large and small diameter nozzles 31, 32 in the subscanning direction is 1/2 of the pitch p2 of the large and small diameter nozzles 31, 32 in the arranging direction D1, D2, nozzle density is increased in the subscanning direction Y. Consequently, burden on a driver 45 is lessened and a small capacity driver can be employed.

Abstract: PURPOSE:To facilitate an easy operation of a robot regardless of the complicated contents of the working, by operating a control robot to the stereoscopic imaginary image of the working subject by means of a stereoscopic mirror and moving a working robot in response to the operation of the control robot. CONSTITUTION:A working robot 12 which performs the working to a working subject 11 follows the same working as that of a control robot 14 which is operated by an operator 13. The industrial TV cameras 16 and 17 which obtain the image of the subject 11 respectively are set in parallel to each other so that the space between the optical axes of the image pickup lenses of the cameras 16 and 17 is equal to the space between the pupils of the operator 13.

The images of these cameras are displayed on a stereoscopic mirror 19, and the image of the subject 11 is observed via the mirror 19. As a result, the operator 13 is confused in thinking that he gives the working to a stereoscopic imaginary image 20 of the subject 11 by means of the robot 14. In such way, a dummy is not required for an imitative operation, and the working is ensured with high accuracy regardless of the complicated contents of the working.

IPC: F22B37/00
Filed: 1993-04-07
Abstract: PURPOSE:To prevent a condensation within a heated area and to enable a control temperature rising rate and temperature changing rate within a desired range, by increasing a heating steam amount little by little while surveying the heating steam amount and temperature in a secondary system pipe. CONSTITUTION:Based on temperature detection by temperature sensors 21A to 21E in secondary system pipes 3 and 4 in a heated area and pressure detection by a pressure sensor 22 in the downstream of the secondary system pipes 3 and 4, it is calculated by a steam control part 23 whether heating steam to be sent into the secondary system pipes 3 and 4 is of a pressure which realizes a saturated state. Only when the heating steam is of temperature and pressure which never cause condensation, an amount of heating steam is increased very little. After that, an operation to detect the temperature and pressure to know whether the heating steam can be increased is repeated. By this, generation of condensation within the heated area can be prevented, and also, a temperature rising rate and a temperature changing rate can be controlled within a desired range.

Title: 4-wire/2-wire converting circuit
Inventor: HAYAKAWA HISATO
IPC: H04B3/20
Filed: 1987-04-02
Abstract: PURPOSE:To eliminate the effect of a transmission signal onto a reception side by inputting a transmission signal in parallel with an amplifier and an inverting amplifier and supplying an output of the amplifier, an output of the inverse amplifier and a synthesizing signal comprising the reception signal inputted via a line coupler to an adder and using the output of the adder so as to control the amplifier. CONSTITUTION:A signal from a transmission signal terminal 2 is inputted to the amplifier 50, amplified to be an amplified signal and inputted to an adder 6. Since the amplitude of the inverting component in the transmission signal in the addition synthesizing signal is fluctuated due to the fluctuation of the line impedance, it stays in the output signal of the adder 6. Then the amplitude of the amplifier signal is controlled by changing the amplification factor of the amplifier 50 so as to eliminate the residual component while the residual component is being detected. Thus, the component of the transmission signal is eliminated surely from the output signal of the adder 6, that is, the signal of the reception terminal 7 independently of the impedance of the line 21.
