Title: Toner residual quantity detecting device
Inventor: TSUCHIYA TAKAHIRO
IPC: G03G15/08
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a stable operation and excellent detection performance at a low cost by comparing the operation quantity of an operating portion and the quantity of image signals, and detecting the shortage of a toner residual quantity. SOLUTION: A controller and a memory section integrate the revolving speed of a feed screw from an operation detection section and pulse signals corresponding to image signals from an image signal readout section respectively, and an arithmetic means comparing the integrated values is formed. The integrated value of the image signals is the quantity of the image signals, and the operation quantity is the revolving speed of the feed screw. The image signal number and the operation quantity of a toner feeding means have a proportionality relation, i.e., a linear relation, theoretically. This proportionality relation is collapsed when the toner quantity in a toner storage means is reduced and the toner conveyance efficiency of a toner feeding means is lowered.  When the relation between the image signal number and the operation quantity of the toner feeding means is drifted from a straight line, the toner quantity in the toner storage means is judged as lacking.

Abstract: PURPOSE:To suppress the thermal expansion of the machine plate of a metallic plate to be exposed and printed and to improve the accuracy of reproducing the fine patterns formed on the machine plate by providing an absorber in an optical path for exposing rays and absorbing the heat ray components of the exposing rays therein. CONSTITUTION:The absorber 4 which absorbs the heat ray components of a long wavelength region of IR rays, far IR rays, etc., of shielding rays 1 in the optical path for irradiation of the exposing rays 1 for printing of the fine patterns is provided on the machine plate 3 of the metallic plate through a master plate 2. The absorber 4 consists of a glass casing 41 consisting of heat resistant glass such as quarts glass and fluid flowing in this casing 41. The inside of the casing 41 is hollow and the fluid injected from an inflow port 42 formed on the lower side in made to flow from a discharge port 43 on the upper side. Bubbles do not, therefore, enter the inside of the casing 41 and the fluid completely shuts off the optical path for the exposing rays passing the casing 41. The thermal expansion effect of the machine plate 3 is suppressed in this way and the reproduction accuracy of the fine patterns formed on the machine plate 3 is improved.

Title: Ocular refractive power measuring device
Inventor: ISOGAI NAOKI
IPC: A61B3/103
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To obtain reliability and ease of measurements in a well-balanced manner by measuring a temporary value for the refractive power of the eye to be examined if alignment is within an allowable range, making variable the allowable conditions for operating distance, and determining whether or not the eye to be examined is within the range of the set allowable conditions.

If the deviation is within a predetermined allowable range, a DC motor 76 is driven to move a target plate together with a moving lens to a position that is conjugate with the fundus oculi of the eye to be examined, and the position to which they have been moved is detected by a potentiometer 78 to obtain a temporary value for refractive power.  Further, the allowable range of operating distances is made variable in accordance with the refractive power value, and when the examinant adjusts alignment of the operating distance by controlling a joystick, a target image produced by a second target projecting optical system is detected to determine whether or not alignment of the operating distance is appropriate.

Abstract: PROBLEM TO BE SOLVED: To supply a constant quantity of ink having an optimal viscosity constantly to an ink jet head regardless of the environmental temperature by detecting the environmental temperature and varying the ratio of ink having different viscosity being fed into a sub-ink tank. SOLUTION: An ink holding member 27 is filled with low viscosity ink and an ink holding member 28 is filled with high viscosity ink. Environmental temperature is detected by a temperature detecting means 36 before a printer begins print operation.

Title: Program circuit
Inventor: YAMAMOTO AKIRA
IPC: H01L27/10
Filed: 1984-09-12
Abstract: PURPOSE:To realize a stabilized programming manner by a method wherein a high resistor and a reverse direction diode as a laser-illuminated type program element in a non-conductive state are serially connected across a power source and a ground power source. CONSTITUTION:A high resistor R3 and a reverse direction diode D1 as a laser- illuminated type program element in a non-conductive state are serially connected across a power source VCC and a ground power source, and an output is collected from a junction point B whereat the high resistor R2 and diode D1 meet. In a circuit of this design, the resistance presented by the diode D1 under ordinary conditions is infinite. It follows therefore that VCC is the voltage outputted from the point B. Illumination of laser on the diode D1 destroys the N-P junction structure, which establishes a current path from the diode D1 to the ground via the point B. The voltage outputted at the point B is programmed at 0V that is the voltage of the ground power source. In this way, the output voltage may be set VCC or 0V respectively before and after programming, ensuring stability for the programming action.

Abstract: PURPOSE:To eliminate the need for a 2nd phase synchronization oscillator, to make the circuit small and to reduce the cost by using an output of one phase synchronization oscillation for frequency conversion and phase comparison. CONSTITUTION:An output signal of a phase synchronization oscillator 8 and an output signal of a 1st frequency divider 2 are mixed at a mixer 3, an IF signal subject to frequency conversion is frequency-divided by a 2nd frequency divider 4 by using its selected frequency division frequency and the result is fed to a phase comparator 5. On the other hand, part of the output signal of the oscillator 8 is branched and inputted to a 3rd frequency divider 7, the frequency-divided output signal is inputted to the comparator 5 as a reference signal. The phases of the two signals inputted to the comparator 5 are compared and its phase comparison output is fed to a voltage controlled oscillator 1 through an amplifier 6. Thus, since the input signal to the mixer 3 and the reference signal input to the comparator 5 are obtained by one oscillator 8 in the phase synchronization oscillation circuit, the circuit is simplified.
