Title: Polishing method for trimming and brushing device for trimming and polishing
Inventor: HAGIWARA HIROSHI
IPC: B24D13/10
Filed: 1986-02-26
Abstract: PURPOSE:To keep constant finished quality, minimize the exchange frequencies of a rotary brush and enable continuous work by comprising the rotary brush of a cup-shaped brush and a cylindrical outer casing, correcting automatically the tip of the projected brush and carrying out a brushing process with the length of the tip kept approximately constant. CONSTITUTION:A rotary brush 3 comprises a cut-shaped brush 6 and a cylindrical outer casing 7 freely slidable along the external side of the brush 6. When the tip of the cup-shaped brush 6 projected from the open end of the outer casing 7 has worn by a predetermined amount, correction is so made automatically as to continue a brushing process with tip length kept approximately constant at all times. Even if the cup-shaped brush 6 is used for a long period and the tip thereof is worn, therefore, the correction of the brush 6 is automatically made, thereby conducting a brushing process with approximately constant tip length at all times. Consequently, brush finished quality can be kept constant. Also, the subject device is simple and in addition, the frequencies of the exchange of the rotary brush 3 become low, thereby enabling continuous work.

Title: Distortion reducing circuit
Inventor: NAITOU MICHINORI
IPC: H04B1/10
Filed: 1981-03-20
Abstract: PURPOSE:To reduce the distortion produced in a band pass filter, by passing an input signal through a band pass filter, after the frequency change in the input signal is decreased through the use of a heterodyne circuit. CONSTITUTION:An output of a voltage controlled oscillator VCO1 (frequency f2) and an input signal (frequency f1) applied to an input terminal IN are multiplied at a multiplier 2 to for a signal in frequency f3=f1-f2. When this signal passess through a band filter 4, it becomes a signal in frequency f4=f3'+f2, after it is multiplied with the output of the VCO1. On the other hand, when an output frequency f2 of the VCO1 is controlled so that it can be changed by a.DELTAf proportional to the change DELTAf in the input signal frequency, the f3 becomes as f3= (f1-f2)+(1-a)DELTAf, and the f3' and the f4 are as shown in EquationsIand II. When the a in Equation above is close to 1, an output reducing the harmonic distortion (DELTAf)<n> of the DELTAf can be obtained.

Title: Transistor amplifier
Inventor: FUJISAWA SEIJI
IPC: H03G1/00
Filed: 1981-03-19
Abstract: PURPOSE:To eliminate a DC preventing capacitor and to miniaturize a circuit, by preventing the application of the DC voltage to a variable resistance element when a transistor, etc. is used to said resistance element. CONSTITUTION:The difference of potential is set at nearly zero between points (a) and (b) of a transistor (TR)5. If the current IC of a control terminal 4 is set at zero, the resistance value between the collector and the emitter of the TR5 is set an extremely high level. Then the input signal current Ii flows into the base of a TR9 virtually as it is and amplified to emerge at an output terminal 12 in the form of the output voltage signal. With increment of the current IC, the collectore-emitter resistance value of the TR5 reduces. Then the current Ii flows also to the TR5, and as a result, the voltage given from the terminal 12 also reduces. In such way, the degree of amplification is controlled.

Title: Production of cold-rolled steel plate
Inventor: HINOTO HAJIME
IPC: C21D9/46
Filed: 1979-04-09
Abstract: PURPOSE:To develop the cold-rolled steel plate production process which is capable of achieving the considerable simplification of descaling process and does not require electrolytic cleaning process by directly cold-rolling the steel plate which has been hot-rolled and deposited with scale and removing the scale through acid treatment then annealing said plate. CONSTITUTION:The steel plate which has been hot-rolled and is held deposited with scale is directly cold-rolled to produce the steel plate of the black surfaces coated with fine power scale. Since this black fine powder scale is thinner is thickness and is more finely pulverized than hot-rolled scale, the percolation of an acid solution by acid treatment in the scale is extremely easy. The scale may be pickled and removed extremely easily by inorganic acid such as HCl and H2SO4 and organic acid such as formic acid. Finally, it is annealed, whereby the steel plate of superior surface characteristic is obtained. With this method, the pickling treatment is extremely simple and there is no need for electrolytic cleaning process, thus the cold-rolled steel plate may be produced at low cost.
