Title: Viterbi decoder
Inventor: WAKAMATSU MASATAKA
IPC: H03M13/41
Filed: 1995-02-28
Abstract: PURPOSE: To obtain the Viterbi decoder in which power consumption of a path memory is reduced. CONSTITUTION: A path memory cell is configured based on two states at the N-th stage and two states of the (N+1)th stage in succession to the N-th stage. Then the inter-stage shift is applied by two flip-flop circuits 41, 42 and 43, 44 which are operated by clock signals whose phases differ by a half period and whose frequency is a half of the system clock signal and selectors 45, 46 selecting outputs of the two flip-flop circuits 41, 42 and 43, 44 respectively and alternately based on the system clock signal. Thus, the operating frequency of the flip-flop circuits for the path memory cell is reduced to a half and the power consumption is reduced.

Filed: 1981-04-27
Abstract: PURPOSE:To adjust the mistimings in sheet transfer by controlling the timing for starting the transfer of the sheet in accordance with the detection signal of a detecting means for the position of an original. CONSTITUTION:The sheet original Os on a sheet original insertion table 55 in an automatic feeder part 51 is fed into the machine by rollers 56, 57.

Title: Driving power transmission mechanism for disk device
Inventor: SAKURAI TOSHIHIRO
IPC: G11B17/04
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a simple driving power transmission mechanism of a disk device by driving a disk carry-in means and a disk discharge means by the same driving power. SOLUTION: A transmission gear 37 is constituted by mutually combining the fitting part 37A1 of an upper gear 37A and the fitting part 37B1 of a lower gear 37B and both are freely movable in an axial direction. Thus, even in the case that a ceiling plate provided with the carry-in means of a disk and a clamp chassis provided with a clamp mechanism, etc., are vertically moved, prescribed driving power is surely transmitted to a large gear (first gear) 36 and a rotary cam (second gear) 7. Thus, the carry-in means and discharge means of the disk are driven by one simple driving power transmission mechanism. Also, since the carry-in operation and discharge operation of the disk are performed at the same time, the required for changing the disk is shortened.

Title: Aluminum-ceramic composite material
Inventor: KOYAMA MAMORU
IPC: C23C28/04
Filed: 1987-03-18
Abstract: PURPOSE:To obtain an Al-ceramic composite material having superior hardness and flexibility of surface layer or a surface-treated Al material by allowing aluminum oxide on the surface of an Al material to react with a copper compd. CONSTITUTION:An Al material is anodically oxidized to form an Al2O3 layer. Fine powder of a copper compd. such as copper alkoxide is uniformly spread on the anodically oxidized Al material and the Al material is heat treated by holding at 510+ or -10 deg.C for 10min in the air. This heat treatment is an essential stage for causing a chemical reaction (diffusion). Conditions during the heat treatment depend on a heat treating apparatus used and are very strictly controlled. By the heat treatment, a ceramic layer consisting of CuxAl2O3, CuO and Al2O3 is formed on the Al2O3 alumite layer. Thus, an Al material having a surface which has superior resistance to wear, corrosion, heat and thermal shock and does not peel off even by bending is obtd.

Abstract: PURPOSE: To realize automation and labor saving, by reducing incorporating and measuring work by constituting this device by means of a shaft, which both ends are provided with stepped portions, a conical roller bearing, a gap-seat plastically deformed and front covers.  
     CONSTITUTION: When both ends of a case open, a gap-seat 16, which can be bent, is inserted between an inner ring 11a of a bearing and a shaft shoulder 13a, and a receiving inner ring of the bearing is inserted into a shaft 13. An outer ring 11b is inserted into the case 14 by utilizing and loading a cope and a drag 18, 17, and the inner ring 11a is pressed into the shaft 13. Bending load from the cope 18 is transmitted to the gap-seat 16 only through the inner ring to plastically deform the gap- seat. Fixed pre-pressure is produced by using front covers 19, 20 in place of the cope and drag 18, 17. Thus, automation can be realized and labor is saved because the pre-pressure of the bearing and the ranges of clearances do not change and incorporating and measuring work is reduced. And pre-pressure does not escape even by impact load because this device can be bent by load not less than static load capacity.

Title: Manufacture of stem for electron tube
Inventor: TAKADA MICHIO
IPC: H01J9/28
Filed: 1988-03-22
Abstract: PURPOSE:To prevent the generation of minute bubbles at the fillet surface of a stem by exposing an inner lead and the connection point between the inner lead and a dumet from the glass in the former press formation, and burying the said connection part in the fillet glass right at a time in the latter formation process. CONSTITUTION:The connection point 1e of an inner lead 21 and a dumet 22 is exposed to the upper side of a fillet glass 10 formed in the former press formation. Following that, the glass is heated to fuse by a burner. After that, a latter press formation is carried out with an upper metal mold 26 and a lower metal mold 4. Since the glass is formed by covering only the dumet 22 in the former press formation, no trouble to generate bubbles occurs. Although bubbles are generated some times between the inner lead and the glass in the latter press process, no heat-fusion process is required after the pressing because it is the final process. Since it is cooled rapidly after that, leaving some bubbles generated inside, no bubble is generated on the fillet surface.
