Filed: 1981-01-28
Abstract: PURPOSE:To obtain a binder having moderate moldability, heat resistance and thermally decomposable property by specifying the max. rate of loss of weight and specifying temp. and loss of weight under heating conditions of specific rates of temp. elevation. CONSTITUTION:This is a binder of which the max. rate of loss of weight is <=25wt%/min and the loss of weight at 450 deg.C is >=30wt% and <=75wt% when it is heated at 20 deg.C rate of temp. elevation per minute in air. This is produced by a method of selecting an org. compound which is, for example, the 1st component, and an initial condensate of a thermosetting resin which is the 2nd component as a combiation wherein a common solvent exists, dissolving this in a solvent, and mixing the soln. with casting sand then evaporating the solvent away  thereby obtaining the sand coated with the mixture of the two components.  Then, this coated sand is packed in core molding molds, and is subjected to a  heat treatment, whereby the sand is bound simultaneously with the partial reaction of the two components and the core molding is obtained.

Title: Developing device
Inventor: YOKOYAMA TOMOAKI
IPC: G03G9/10
Filed: 1993-01-28
Abstract: PURPOSE:To obtain a very high image density in an image forming device. CONSTITUTION:The same pole part in which two magnetic poles N1 and N2 having the same polarity are adjacent to each other, is provided to be opposed to a photosensitive body on the outer periphery part of a fixed magnetic body 7, and the carrier of developer is set so that its average particle size is >=25mum, its magnetic amount is >=30emu/g, and the filling ratio of the developer in a developing area is 5% to 40%. Since the carrier is adjusted so that its average particle size is >=25mum, and its magnetic amount is >=30emu/g, the developer is sufficiently stirred by receiving the effect of repulsive magnetic field very much. In addition to that, the filling ratio of the developer is set to 5-40%, thereby the stirred developer is efficiently brought into contact with the photosensitive body. Therefore, the contact frequency of the stirred developer with the photosensitive body becomes high and the sufficient toner is supplied to an electrostatic latent image formed on the photosensitive body and a high image density is obtained.

Title: Supervising system for digital subscriber line trouble
Inventor: TSUTSUMI KENJI
IPC: H04L69/40
Filed: 1989-01-20
Abstract: PURPOSE:To let a person in charge of maintenance know abnormality of a subscriber line early by supervising the output voltage of a feeding circuit and making a warning display when the output voltage exceeds a specific voltage range. CONSTITUTION:The voltage across the resistance R1 of a wire breaking detecting circuit 6a has a constant value irrelevantly to the resistance value of the subscriber line 3. The wire breaking detecting circuit 6a sets this voltage as the reference voltage value of a comparator COMP1 and inputs the voltage across the resistance R1 to the comparator COMP1, which compares it with the reference value. When the subscriber line 3 is broken, no current flows, so the voltage across the resistance R1 becomes 0 and a warning display circuit 6c sends out information for warning. When the subscriber line 3 short-circuits, on the hand, the feeding circuit 4 lowers a fed voltage. The output voltage of the feeding circuit 4 is inputted to one input of the comparator COMP2 of a short-circuit detecting circuit 6b and the output voltage of the feeding circuit 4 when the subscriber line 3 is normal is inputted to the other input as a reference voltage value. Consequently, if short-circuit trouble occurs on the subscriber line 3, the output voltage of the feeding circuit 4 becomes lower than the reference voltage, so that is detected as abnormality and the warning display is made.

Title: Ink jet recorder
Inventor: YAMAUCHI MINEO
IPC: G01D15/18
Filed: 1979-02-06
Abstract: PURPOSE: To enable a recorder to follow up a phenomenon with high response speed by a method wherein a means which controls the generation of ink drops in proportion to alteration in the volume of a unit at a recording head so as to make roughly constant the density of ink drops forming a recording image despite the alteration in recording speed.  
     CONSTITUTION: When a recording head 1 draws a linear recording image between a point B and a point C after it has moved from the location of a point A to that of the point B, a command signal S 3  is set to 0 while it is moving from the point A to the point B, and the transmission of the output signal of a synthesizer 53 from a gate 54 is suppressed. On the other hand, S 3  signal is set to 1 while the head is moving from the point B to the point C, and the output signal of the synthesizer 53 is applied to an ink jet pen 11 as a driving signal S 4 . Since the ink drops are generated according to the signal related to pulse signals S 1 , S 2  for changing the position of the recording head 1 by every volume of the unit specified, the density of ink drops for forming the recording image is made constant despite the alteration in recording speed. Thus the recorder can follow up a phenomenon with high response speed to produce a recording image of good quality.
