Title: Detecting method of toner concentration and device for the same
Inventor: OOTA WASABUROU
IPC: G03G15/08
Filed: 1977-10-28
Abstract: PURPOSE:To make possible toner concentration detection of an electrophotographic copier of  two-color development by applying potential of different polarities to the two transparent electrodes provided in the passage way for developer, letting the toner having been charged to different polarities deposit on both electrodes, applying light thereto and detecting the transmitted light. CONSTITUTION:When a channel changeover means 4 actuates to communicate pipe 72 with  pipes 73, 75, the developer having been drawn out by a pump 3 is returned to a developer tank  through the pipes 73, 74 and 76 of the concentration detecting channel. If, at this time, e.g., a  transparent electrode 50 has been applied with potential of a negative polarity and 50' with that  of a positive polarity, then the black toner having been charged to positive is attracted to the electrode 50 and deposits thereon and the red toner having been charged to negative is attracted to  and deposits on the electrode 50'. At the same instant of potential application, a light source lamp  6 has been lighted and the light therefrom tranamits through the developer flowing in the pipe 74  and the electrodes 50, 50'. The light transmittance is detected with photo detectors 51, 51'. The  intensities of the transmitted light of the respective electrodes are inversely proportional to the  quantities of the respective toners deposited on the electrodes, thus the concentrations of the  respective toners may be detected simultaneously.

Title: Cleaning cassette
Inventor: KUWABARA MASAAKI
IPC: G11B5/41
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning cassette which can correctly inform the user of a cleaning life. SOLUTION: An upper disc 14b of a reel 14 is rotatable to a rotary shaft 14a. A moving member 24 rotates when loaded to a recording/reproducing apparatus and returns when taken out of the apparatus. In consequence of the operation, the leading end of a driving member 32 rides over one sawtooth of the disc 14b, rotating the disc 14b by a fixed angle. An arm 40 is urged by a coil spring 41 in a direction to the disc 14b, thereby preventing the disc 14b from rotating reversely. A magnet 48 is fixed at the leading end of the arm 46 and a pin 50 is erected at a middle point of the arm. The arm 46 is biased by a coil spring 52 to butt with a circumferential edge of the disc 14b. When the disc 14b rotates by not smaller than the fixed angle, the pin 50 enters a slot 30 of the disc 14b. If the disc 14b further rotates, the magnet comes in touch with a cleaning tape 15.  The image recorded on the tape is erased, so that the user can know the life.

Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To limit the range to search for a data part corresponding to a retrieval key by arraying the document information for every group to which the corresponding key item belongs, and retrieving and outputting the document information in response to input of the retrieval key. SOLUTION: The occurrence frequency of the key item of each document stored in a document data base 101 is obtained via the actions of a word detection means 111 and a count means 113. Accordingly, a 1st sort means 114 sorts the key items and an array means 115 changes the array of the document information held at a document information holding part 112 based on the sort result of key items. Thus, the distribution range of the means 112 can be limited for the document information corresponding to the key items of similar occurrence frequency. Then a retrieval means 116 can limit the searching range of the means 112 for the desired document information by controlling the distribution range of document information in response to the occurrence frequency of key items.

Title: Temperature controlling device for heater for cooking
Inventor: NAKAMOTO SHIGEHARU
IPC: F24C15/10
Filed: 1983-07-18
Abstract: PURPOSE:To enhance the performance of a heater for cooking, by improving the follow-up action of a temperature sensor for the material to be cooked, by making calorific value small at the time when the temperature in oil is stabilized before a load to be heated in thrown into it, and by making the value large when a load is thrown into it. CONSTITUTION:The reference values T and T1 to compare them with the temperature (a) and an output power W are determined previously. The oil should be heated with full power W0 when the temperature in oil is rising. When the temperature in a temperature sensor 2 reaches the reference temperature value T, a heater 1 is turned OFF. When the temperature in the temperature sensor 2 (d) is lowered, the heater 1 is turned ON, but as the rising time of temperature (c) has finished, the oil is heated by the reduced output power W, then the temperature in oil (f) is gradually raised. The temperature sensor 2 is controlled by the temperature value T, though hunting is generated. When material to be fried is thrown into the oil as a load, the temperature in oil is suddenly lowered, and the temperature in the temperature sensor 2 is also lowered below the temperature reference value T1. Then the sensor 2 gets to a load throw-in mode (e), the calorific value (g) is set to the maximum, the oil is heated with full power W0 within a set time (b), to return to the specified temperature quickly. When the temperature in oil is returned, the load throw-in mode is released and the sensor is restored to the normal heating mode.

Abstract: PURPOSE:To control satisfactorily meandering without causing any hindrance in rolling by storing the position of a rolling material in its width direction basing on a biting signal of material and providing a means which gives the stored signal as a target value of the control quantity of meandering. CONSTITUTION:When the tip of a rolling material (a) is bitten by a rolling mill 1, a load cell 3 detects it and outputs a signal 6 of the change of a rolling down force to a comparator 7. After comparing the load signal 6 with a set signal 8, a biting signal 10 is inputted to a timing-generation circuit 9, which outputs a timing signal 11 to a storage circuit 12. A signal 20 of a meander detector 13 is previously inputted to the circuit 12, in which the position of material (a) at the time of inputting the signal 11 is stored. The position of material (a) is inputted to an adder 14 as a target-value signal 19, to output its deviation 16 from the position signal 20 outputted from the detector 13 to a meander controlling adjuster 15 so as to treat the deviation. A roll gap is adjusted by controlling a rolling reduction device 2 basing on the treating signal to control the position in the width direction of material (a) to the position at the time of biting.
