Title: Measuring circuit for characteristic of decoder
Inventor: KARIBE HIROHISA
IPC: H03M1/10
Filed: 1980-06-06
Abstract: PURPOSE:To measure the input and output characteristics of a decoder which does not respond to DC input by measuring the input and output characteristics of the decoder by using the sine waves, etc. of specific frequencies, and arbitrary input signal waveform. CONSTITUTION:Digital sine waves are generated from a digital signal generating circuit 10. The frequency thereof is set in the pass area of the last filter of a decoder (DUT) 2 to be measured.

IPC: H03M1/38
Filed: 1986-04-04
Abstract: PURPOSE:To prevent generation of periodic signals and at the same time to attain the fast operation and high image resolution with an A/D converter, by using the lst A/D converter to give A/D conversion to a higher bit part and then the 2nd A/D converter to apply A/D conversion to a lower bit part requiring high accuracy. CONSTITUTION:An A/D converter ADh is actuated by a control line and the A/D conversion data is produced. This A/D conversion data is converted again into analog signal and supplied to a differential amplifier IA as an analog signal A3. At the same time, the output signal A2 of a sample and hold circuit SH is also applied to the amplifier IA. Thus the output value of the amplifier IA is equal to the differential between the output signals A2 and A3. This differential is fractionated by voltage dividing resistances Rl-R4 and comparators CP1-CP3 and encoded by an encoder EN. Then the final A/D conversion data ADT is obtained with the output DT2 and the output DT1 of the converter ADh used as the lower and higher bits respectively.

Filed: 1983-05-02
Abstract: PURPOSE:To fabricate a cam shaft excellent in durability in good yield, in fabricating the cam shaft, by molding a substrate material into a predetermined profile while vapor depositing a hard metal compound to the cam part of the molded one by a chemical vapor deposition method. CONSTITUTION:A cam shaft substrate material to which a fundamental shape is imparted by casting and the other mechanical processing is preformed precisely so as to obtain a predetermined cam profile. In the next step, the molded one is put in a reaction furnace for chemical vapor deposition and heated to 1,000- 1,200 deg.C. On the other hand, TiCl4 is gasified by heating the same to 20-80 deg.C and sent into the reaction furnace along with CH4 and H2 being carrier gases. TiCl4 and the carrier gases are chemically reacted on the surface of the cam shaft substrate material in the furnace to form TiC and HCl while TiC among them is precipitated to the surface of the cam shaft substrate material to form a hard TiC vapor deposition layer. Because the largest load is especially applied to a cam nose part Cn, the life of a cam is prolonged by the enhancement of the abrasion resistance of said part.

Title: Brake containing type bearing and roller device fitted with the bearing
Inventor: HARA AKIRA
IPC: B65H27/00
Filed: 1994-03-24
Abstract: PURPOSE:To enable a roller main body to brake rotation by utilizing the outer race and the inner race of a bearing. CONSTITUTION:Bearing balls 35 held with a retainer 34 at decided intervals and a tubular expansion member 37 are arranged between an inner race 31 and an outer race 32, and the inner race 31 is rotatably supported with the bearing balls against the outer race 32. The expansion member 37 is expanded by air injected through the air injection port 41 provided on the roller shaft 21 of a roller main body 22 or the air injection port provided on the inner race, and its outer circumferential face is directly pressed against the outer race for braking. Because the expansion member is contracted at non-supply of air, the braking force of the expansion member is released to be in non- braking condition. Hereby, a brake mechanism for the roller main body is simplified, the fitting space of the brake mechanism can be remarkably saved, and a roller device having brake function can be miniaturized.
