Patent JP-S5910183-A (JP)
Title: Motor with revolution detector
Inventor: BAN ITSUKI
IPC: G01P3/487
Filed: 1982-07-07
Abstract: PURPOSE:To obtain a rotating speed signal which does not contain a ripple voltage by attaining the rotating speed signal with the counterelectromotive force of an armature coil of a motor and the intensity of a field of the motor. CONSTITUTION:The counterelectromotive forces of armature coils 2a, 2b are added by an adder 19a through absolute value circuits 17a, 17b. On the other hand, the outputs of Hall elements 3a, 3b are added by an adder 19b through absolute value circuits 18a, 18b. An error amplifier 20 operates so that the product of the output of the error amplifier and the output of the adder 19b becomes equal to the output of the adder 19a. The output of the amplifier 20 is outputted as a rotating speed signal through a switch 24a when a field magnet normally rotates and through a switch 24b when it reversely rotates. In this manner, the rotating speed signal which does not contain ripple contents can be obtained.

Title: Tone detection circuit
Inventor: YOSHIDA IKUO
IPC: H04M1/64
Filed: 1988-05-16
Abstract: PURPOSE:To surely prevent detection error due to a voice signal by providing a circuit constitution comprising a PLL circuit, a band pass filter, a rectifier circuit and a comparator so as to detect both the tone frequency and the burst frequency. CONSTITUTION:A signal waveform 21 is, that is, an input waveform of a voice signal, and inputted to a PLL circuit 3. The PLL circuit 3 detects a signal component close to the tone frequency in the voice signal as shown in a signal waveform 22. However, the signal detected in error is given to a band pass filter 4 and a rectifier circuit 5, then the signal is suppressed as shown in waveform 23. Thus, the input signal to the comparator circuit 6 does not exceed a threshold value 23a, resulting that the tone detection output keeps the state of the absence of a tone burst signal, then the mis-detection is surely prevented.

Title: Unit releasing mechanism for facsimile equipment
Inventor: WASHIO TAKESHI
IPC: H04N1/00
Filed: 1987-05-15
Abstract: PURPOSE:To easily perform maintenance work even in a narrow space, by turning a scanner supporting bracket, and releasing the contact with pressure of a plotter side. CONSTITUTION:When the jamming of an original is generated, or the cleaning of an original reading part is performed, by releasing the lock of a roller supporting bracket 103 and turning the upper part of a front cover 5 to a front side, a glass plane 101c can be separated from a platen roller 104. Thereby, a jammed original can be removed, and the cleaning of the glass plane 101c and the roller 104 can be performed. Thus, since all of the ordinary required maintenance work can be performed from the front side of the device, it is possible to easily perform the maintenance work of a facsimile equipment even in the narrow space such as the inside of an automobile.

Filed: 1984-06-07
Abstract: PURPOSE:To save a breakdown quantity of grain, and also to measure exactly moisture of the grain by storing temporarily a sample crushed by a grinding roll, and measuring the moisture by rotating an electrode roll after storing by some quantity. CONSTITUTION:A sample storing chamber 3 is formed by closing up the part between grinding rolls 1, 1 and electrode rolls 2, 2 by right and left parallel partition walls 4, 4 and covering the front of each roll with a vertical cover plate 5.

Title: Laminated coating film superior in designing properties
Inventor: AOYAMA HIROMI
IPC: B32B7/00
Filed: 1988-05-14
Abstract: PURPOSE:To constitute the subject coating so that it is superior in designing properties without conspicuous coating irregularity even if the coating irregularity is generated on a mica base layer to be formed on the surface of a color base layer, by a method wherein at least either of mica powder or aluminum powder is contained in the color base layer. CONSTITUTION:A laminated coating is constituted of a color base layer 2 formed on the surface of a metallized coating layer formed on the surface of a steel sheet 100, a mica base layer 3 formed on the surface of the color base layer 2 and a clear coating layer 4 formed on the surface of the mica base layer 3. At least one side of the mica powder or aluminum powder is contained in the color base layer 2. Therefore, when, for example, a front view of the subject coating is taken, the coating becomes a design where pearl gloss with the mica powder of the mica base layer 3 is exposed. In this instance, when irregularity is generated on the mica base layer 3 with the coating irregularity, on a part where the mica powder is little, the mica powder or the aluminum powder of the color base layer 2 is exposed, deficiency in the mic powder of the mica base layer 3 is compensated and the irregularity is eliminated.

The controller 10 drives a flocculating agent pump 7 basing on the inputted operated value to transfer a flocculating agent stored in a flocculating agent storage tank 12 to the raw water tank 2; the controller 11 operates basing on the simultaneously inputted operated values to transfer the flocculating aid stored in a flocculating aid storage tank to the stirring tank 3 by a pump 8. Flocculated product is settled and separated in the flocculating and settling tank 4.
Patent JP-S61276367-A (JP)
Title: Manufacture of semiconductor device
Inventor: HARA TOMOI
IPC: H01L29/732
Filed: 1985-05-31
Abstract: PURPOSE:To obtain a high withstanding bi-polar IC which has a reduced hFE and can prevent VCE(sat) from increasing, by forming an N epitaxial layer with an SiCl4 source on a P-type Si substrate having an N layer and a P layer buried, by burying a P layer, and by overlapping an N epitaxial layer with a small specific resistance thereon with an SiH4 source. CONSTITUTION:On a P<-> Si substrate 1, an N<+> layer 2 is buried by diffusing As, then a P layer 3 is buried by diffusing BCl3 and an N<-> epitaxial layer 4 is overlapped with a reducing reaction of SiCl4 at about 1,170 deg.C. By diffusing BCl3 from the surface, a P layer 5 is buried over the layer 3, and by thermal decomposition of SiH4 at about 1,050 deg.C, an N<-> epitaxial layer 6b is overlapped, with self-addition of B being less than the layer 4. In this way, an inverted layer or a high resistance layer can be prevented from occurring at the interface between the epitaxial layers, and if the layer is increased in concentration, the self-addition can be perfectly eliminated. Accordingly, if an NPN transistor is made, with a P layer 10 being formed, which separates the epitaxial layers 4, 6b, an extremely high diffusion yield can be realized without reducing the hFE and increasing the VCE(sat).

Title: Decarbonization method of molten steel under reduced pressure
Inventor: UCHIBORI HIDEO
IPC: C21C7/068
Filed: 1979-09-17
Abstract: PURPOSE: To decarbonize and refine molten steel without eroding blowing tuyeres by blowing CO 2  gas into molten steel from the underside of the steel bath at the time of degassing and refining the molten steel with an RH type vacuum degassing device etc.  
     CONSTITUTION: The molten steel 5 to be refined is put into a vessel 1 such as ladle, and reflux pipes 4, 4 for molten steel of an RH vacuum vessel 2 are immersed therein. The inside of the vacuum vessel 2 is exhausted and evacuated to blow the molten steel in the vessel 1 into the vacuum vessel 2. On the other hand, an inert gas such as Ar or N 2  is blown through the lower tuyere 6 of one reflux pipe 4 and is allowed to ascend as bubbles. The action thereof causes the molten steel 5 in the vacuum vessel 2 to be circulated with the molten steel in the ladle 1 through the two reflux pipes 4, 4, whereby the molten steel is degassed and refined in the vacuum vessel 2. At the same time, CO 2  gas is blown through the tuyere 3 under the steel bath surface in the vacuum vessel 2 so that the C in the molten steel is decarbonized and refined by C+CO 2 =2CO. Since the said reaction is endothermic reaction, the tuyere 3 is cooled and the erosion of the tuyere 3 owing to a high temperature does not occur.
