Title: Spread spectrum communication equipment
Inventor: MOCHIZUKI NORIHIRO
IPC: H04B1/707
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain a proper threshold value, and to ensure stable transmission quality by estimating DC components based on a demodulation signal, and changing the threshold value of a judging means according to the DC components. SOLUTION: An output from a mixer 11 is converted through a low pass filter 12 into a base band signal, and extracted. Then, DC components are removed through a high pass filter 13, and this signal is inputted to a correlative demodulating circuit 14. Moreover, a spreading code synthesized with the received signal is inputted from a code generator 17 to the correlation demodulating circuit 14, and the correlative arithmetic operation of both the signals is performed, and a frequency spread signal is inverse spread according to the spreading code. The inverse spread signal is compared with a threshold value by a judger 15, and data modulated. In this case, the threshold value of the judger 15 is decided by a threshold value control circuit 19 from the DC components detected by a DC component detection circuit 18 from data demodulated by the judger 15.

Title: Rivet and rivetting method
Inventor: TERADA ATSUSHI
IPC: F16B19/08
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To simply tighten a groove part by performing the tightening making use of the stress generated in binding metals due to the stress generated by the press-fitting and work hardening generated by the deformation of projected and recessed bars to tighten plates using a simple lower hole. SOLUTION: Plates 1, 2, 3 are made of ductile, non-ferrous metal, e.g. copper and aluminum. A rivet 2 tightens the plate 1 with the plate 2 without overlapping them, and a rivet 3 tightens the plate 2 with the plate 3 in an overlapping manner. Recessed and projected bar parts 2c, 2d, 3c, 3d which are corresponding to each other are provided on the joining surface of the metallic plates 2, 3 to be joined. The projected bar parts 2c, 2d, and/or the recessed bar parts 3c, 3d are provided with a part with the prescribed angle. Metals are bonded with each other by the stress generated by the press-fitting in press fitting the projected bar parts 2c, 3c into the corresponding recessed bar parts 2d, 3d, and by working hardening caused by the plastic deformation generated by the deformation of both parts at a corner part.  Bonding is performed making use of work hardening thereby to produce rivets at a low cost.

Title: Cutting method of continuously cast steel ingot
Inventor: TERADA OSAMU
IPC: B22D11/16
Filed: 1984-09-14
Abstract: PURPOSE:To permit the unattended cutting operation by moving two gas torches from both end sides of an ingot toward the center to cut the ingot, moving effectively the respective torches to the detected part remaining without being cut and cutting said part. CONSTITUTION:The two gas torches are brought above the ingot from both sides in the transverse direction and are moved at a low speed VL toward the central part F where the beginning parts D, E for cutting are cut. The ingot is then cut to the central part F at a high speed VH along lines (b), (h). The central part F is further moved at a middle speed VM and thereafter the one torch is returned to the part E along the line (j) and the central part F is cut by the other torch in lapping. When the part of the ingot remaining without being cut is detected by a detecting means, both torches are effectively moved and the thorough cutting without the uncut part is executed. The unattended cutting is thus made possible by the above-mentioned method.

Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous reading of information data to be displayed in a displaying section so as to improve the reliability of the displaying section by providing a displaying attitude setting means which can arbitrarily change the displaying attitude of information data. SOLUTION: A display device is provided with a measuring section 6, a displaying section 7, a displaying attitude setting section 8, and an installed state setting section 9. When the display device is installed, the installed attitude of the device is first set manually by means of the section 9.

Since the displaying attitude including the erected attitude, inverted attitude, oblique attitude, etc., and aspect ratio of information data to be displayed in the section 7 can be changed by means of the section 8 in accordance with the installed attitude of the section 7, the degree of freedom in the installed attitude of the section 7 can be increased and the display device can be installed easily.  The section 7 can be constituted to display one character by combining bar-like segments or by arranging dots. In either case, the structure of the section 7 can be simplified and the number of parts can be reduced.

SOLUTION: A drain B is inserted in an insertion hole 23 bored on the bottom face of an eaves gutter A and a vertical drain pipe C is fitted from the lower side and a rejecting device 14 of fallen leaves, curved to form a mesh is fitted to the drain B. And a protection plate 15 that a zinc plate or a zinc alloy plate is folded, is fitted to the body 1 of the drain B, the outer peripheral face side of the erected part 11, and the inner peripheral face side of the dropping water cylinder 13. Rainwater flowing down from the eaves gutter A is collected in the drain A and discharged to the vertical drain pipe C. In this time, acidic rainwater contacts the zinc protection plate 15 arranged at the central periphery of the drain B and neutralizes the acidity of rain water to a neutral condition and then, flows out from the vertical drain pipe C of the dropping water cylinder 13.  Accordingly, the eaves gutter drain can prevent corrosion of the vertical drain pipe resulting from acidic rain and prevent harmful influence on the environment even after it has been drained on the ground.
