Title: Monitor for multilayer type extruder
Inventor: SAIKI JIRO
IPC: B29C48/92
Filed: 1990-05-12
Abstract: PURPOSE:To prevent the breakdown, etc. of filters in extruders by monitoring the material consumption of each extruder of a multilayer type extruder and sounding an alarm when the material consumption is abnormal. CONSTITUTION:Weighing sensors 15, 25 for each extruder 11, 21 weigh the weight of materials in each hopper, and output the weighing signals. A material- consumption computing means 1 computes mean consumption per a unit time on the basis of weighing data from the weighing sensors 15, 25. On the other hand, a variation-range decision means 3 compares the current consumption of each extruder and reference material consumption read from a storage means 2, and decides whether or not the difference exceeds an allowable variation range preset. When the difference exceeds the allowable variation range, an alarm generating means 5 generates an alarm. A relative-deviation decision means 4 relatively compares the current consumption of each extruder, and devices whether or not the difference exceeds an allowable relative deviation preset. When the difference exceeds the allowable relative deviation, the alarm generating means 5 generates an alarm.

Title: Transistor circuit
Inventor: MATSUE SHIGEKI
IPC: H03K19/096
Filed: 1978-10-02
Abstract: PURPOSE:To decrease the power consumption at the non-active time by providing the 1st and 2nd inverse circuits constituted by FET and then connecting the capacity between the gate and the source of the load FET in the 2nd inverse circuit. CONSTITUTION:The 1st inverse circuit consisting of FETQ11 and Q12 is provided along with the 2nd inverse circuit comprising FETQ21 and Q22, and capacitor C22 is connected between the gate and the source of load FETQ22 in the 2nd inverse circuit. When timing pulse phi is at a low level, output phi1 features a high level and phi2 features a low level respectively. Thus, no power is consumed by the two inverse circuits. When timing features a high level exceeding the level which is lower than power source VDD by threshold voltage VTH, phi2 features a low level with FETQ21 turned off. And FETQ23 is turned off since its gate is connected to the power source, and the charge at point B does not go away, thus obtaining the function of a high-efficiency bootstrap circuit. Thus, phi2 is turned to a high level. When phi is lowered, the level of point B can be lowered down suddenly through FETQ23. Thus, the power consumption can be decreased.

Title: Image-reading and recording device
Inventor: INADA AKIRA
IPC: H04N1/04
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the need to provide a paper size detection sensor in each kind and to miniaturize this device by detecting the front and termination of document because an output of an image sensor changes to be irregular, when the document enters in an image sensor part according to a carrier path and also, becomes regular again when it comes out of the part. SOLUTION: When a document does not reach an image sensor CIS 24, its output outputs a regular signal. On the other hand, when document arrives at the a reading position of the CIS 24, the CIS 24 outputs an irregular signal. A main controller 46 recognizes a position where the CIS 24 output changes, i.e., where a regular signal changes into an irregular signal as a front position of the document and the position where an irregular signal changes into a regular signal as the terminal of the document at the CIS 24., In this way, the front and termination of document are detected with the changes in the output signal of the CIS 24, which enables detecting the vertical length of the document.

Title: Gradation recording method
Inventor: MENTANI MAKOTO
IPC: B41J2/52
Filed: 1984-06-15
Abstract: PURPOSE:To enable high-speed recording with excellent gradation reproeducibility while using a simple circuit, by a method wherein when a voltage varied with the same period as a recording period is impressed on one of two controlling electrodes, and a pulse form voltage having a pulse width corresponding to a recording signal is impressed on the other. CONSTITUTION:The voltage V1 varied with the same period T as the recording period is impressed on an upper controlling electrode 3, while the pulse form voltage V2 having a width according to a recording density within the recording period T is impressed on a lower controlling electrode 4, and an ion flow is passed only in the presence of an ON pulse of the voltage V2, thereby forming an electrostatic latent image on a recording medium 5. Accordingly, since both of the voltages V1, V2 impressed on the controlling electrodes 3, 4 are controlled, it is possible to arbitrarily set the potential difference between the electrodes 3, 4 and therefore, the variation with time of the intensity of an electric field at the time of passing the ion flow, by controlling the timing of ON/OFF signals impressed as the voltage V2 and the pulse width of the ON signals, or by controlling the waveform of the voltage V1.

Title: Optical measuring device of rotation precision
Inventor: FUJIMOTO YASUKAZU
IPC: G01B11/14
Filed: 1983-07-05
Abstract: PURPOSE:To improve the measurement precision by allowing a measuring member to face the outside circumference of a rotating body with a proper gap between them and scanning this gap with a spot light and detecting a prescribed higher harmonic component of the transmitted light to measure the width of the gap. CONSTITUTION:The tip of measuring member 2 is allowed to approach the outside circumference of a rotating body 1 to form a gap between Them. The laser light emitted from a laser oscillator 4 scans the gap as a scanning beam through an oscillating mirror 9. The light transmitted through the gap is converged by a light receiving optical system 15 and is converted photoelectrically by a photoelectric multiplier 14. The electrical signal is inputted to a lock-in amplifier 17 through a preamplifier 16. The amplifier 17 detects and outputs a prescribed higher harmonic component out of Fourier series components of the electrical signal. This output signal corresponds to the width of the gap, and the rotation precision of the rotating body 1 is measured on a basis of this signal.

Title: Minute light power meter
Inventor: TOUGE TAKASHI
IPC: G01J1/42
Filed: 1977-10-14
Abstract: PURPOSE:To enable extremely minute light power to be measured as well without any error by making use of the measuring light having been so modulated as to enable the characteristics of a mechanical light chopper and a synchronous detector to be fully exhibited or the a.c. signal so converted therefrom. CONSTITUTION:The reference signal used in a synchronous detector 5 is drawn out from the sigbal under a.c. amplification and it is for this purpose that the  output of an a.c. amplifier 71 is branched in two ways. The output having undergone synchronous detection in the synchronous detector 5 by using the signal having no phase difference in this way is invariable in indication value and is effective as a minute light power meter. The purpose of insertion of an amplitude limiter 8 lies  in taking the feasibility of the use of a d.c. watmeter 6 even if it is a true number  display into consideration. Namely, as the measuring light becomes smaller, the output voltage becomes smaller in proportion to the square of the reduction in the measuring light. Hence, in the case of true number display, the synchronous detection output proportional to the input signal may be obtained by passing the same  through the amplitude limiter of a wide dynamic range.
