Filed: 1979-09-05
Abstract: PURPOSE:To make a construction simple and small, by detecting a bottom surface of a paraboloid of recovered ink which will be formed in a liquid reservoir when the recovered ink is rotated by a stirring rotor at a certain speed thereby assessing relatively the viscosity of the recovered ink. CONSTITUTION:Viscosity detection of recovered ink will be carried out at certain time intervals when a certain quantity of the ink in a reservoir tank 19 is transferred to the liquid reservoir 22. When this is carried out, a three-way electromagnetic valve 21 is opened to set a liquid surface in the liquid reservoir 22 to a standard surface A. Then when the stirring rotor 26 is rotated at a certain speed, the ink surface will form a paraboloid, and if the ink viscosity is high, the bottom ink surface is lowered, while if the ink viscosity is low, the bottom ink surface is risen. Accordingly, when a liquid surface detection probe 23 arranged in place is not in contact with the ink surface when the ink viscosity is high, it is assessed that the ink apparatus has a value above a prescribed value, and ink in a supplementary liquid cartrige 10 is supplied to the recovered ink to thin it.

Title: Facsimile equipment
Inventor: YASUDA NOBUYUKI
IPC: H04N1/21
Filed: 1989-05-02
Abstract: PURPOSE:To select the best line density and to shorten a transmission time by deciding whether or not there are many change points on the line of a binary-coded signal train from a read part at the time of accumulating as to one page when data are sent out and determining the line density from the result automatically. CONSTITUTION:For example, when the number of change points on one line exceeds 30% of the total number of lines of one page, it is decided that the amount of information of the page is 'large'. Then a decision part 3 for the number of change points in one page outputs information for 'high line density', i.e., line density information 13 at the time of re-encoding. An encoder 4 encodes the binary-coded signal train 11 with 'high line density' by an M<2>R system at the time of re-encoding to match the ability of an opposite-side receiver, and accumulates the encoded data 14, page by page, in pairs with the line density information 13. Then when a large amount of data are broadcast from a memory 5 to many places, they are sent out with the best line density matching the amount of information according to the line density information 13.

Title: Semiconductor device
Inventor: OTSUKA AKIO
IPC: H01L21/331
Filed: 1988-05-09
Abstract: PURPOSE:To improve the low current side hFE by making a highly doped base region in the silicon substrate exposed side of the base region of emitter base junction. CONSTITUTION:Electrodes 5, 6 are constituted after a base region 2 and an emitter region 3 are formed on a collector substrate 1 in a specified way. At that time, a highly doped base region 7 is formed in the substrate exposed side of the base region 2 of an emitter base junction. It is desirable that the highly doped base region 7 should be diffused just after the base region 2 being formed, before the formation of the emitter region 3. Constituting the highly doped base region 7 like this makes it possible to improve the low current side hFE ratio to 0.95 or more. It is because injection of minority carriers of the base surface part which have been dominant on the low current side was suppressed, and increase of base recombination current was able to be prevented, by providing the highly doped base region 7.

IPC: F24H3/04
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To quickly bring temperature closer to a target room temperature and at the same time achieve comfortable heating by switching to a special maximum amount of combustion that is larger than the maximum amount of combustion corresponding to the maximum number of tatami mats and then returning to a value corresponding to the set number of tatami mats, and at the same time performing control based on a room temperature. SOLUTION: Suppose that the setting of a switcher 8 for the number of tatami mats is 8, that of room temperature setting equipment 5 is 20 deg.C, and a room temperature being detected by a room temperature detector 4 is 5 deg.C. When an operation/stop switch 2 is operated under the conditions, a central control device 3 switches the maximum amount of combustion to the special maximum amount of combustion that is larger than the maximum amount of combustion corresponding to the maximum number of tatami mats. Combustion by the special maximum amount of combustion is made only for 15 minutes before returning to the maximum amount of combustion for heating an eight-mat room to try to reach 20 deg.C with the maximum amount of combustion.  In addition, when the detection temperature of the room temperature detector 4 approaches the setting value of the room temperature setting equipment 5, a target heating temperature can be maintained.

Title: Drive controller for stepping motor
Inventor: NORO MASAHIKO
IPC: G11B21/02
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a drive controller for stepping motor which can-transfer at a high speed a body to be driven to a target position on a body to which the body is to be transferred, even when the self-starting frequency of the body to be driven is low at the starting time. SOLUTION: A stepping motor 16 which transfers a carriage 14A mounted with a magnetic head 14 transfers the magnetic head 14 to a target position on a floppy disk 17, when a drive pulse having a prescribed duty ratio is supplied to the motor 16. When the magnetic head 14 is accelerated, a drive circuit 6 shortens the supplying period of the drive pulse having the prescribed duty ratio, and when the head 14 is decelerated, the circuit 6 prolongs the supplying period of the drive pulse. Therefore, the magnetic head 14 can be positioned to the target position on the floppy disk 17 with good accuracy in a short time, because the head 14 is accelerated when the drive pulse is impressed upon the head 14 in the short period after the head 14 has started to run and decelerated, when the drive pulse is impressed with a long period, while the head 14 is run at a high speed.
