Inventor: MURAMATSU TAKEO
IPC: B62D55/253
Filed: 1992-01-23
Abstract: PURPOSE:To secure the engagement between an angular part projecting from the inner peripheral surface of a rubber crawler, with a sprocket and a roller CONSTITUTION:A core metal is equipped with a blade part 21 embedded in lateral arrangement form perpendicularly to the longitudinal direction in a rubber crawler and an angular part 22 for drive which is at the center of the blade part 21 and projects from the inner peripheral surface of the rubber crawler. The angular part 22 is formed to an arcuate outer peripheral surface 221 having a nearly equal width in the longitudinal direction of the rubber crawler, and the left and right surfaces 222 of the angular part 22 form a curved surface 224, starting up from the blade part surface 21, having the max. width at the center part. The arcuate outer peripheral surface 221, and the left and right curved surfaces 222 which form the angulat part 22 are connected by a projecting curved surface having a small radius of curvature. Accordingly, the engagement between the angular part of the core metal with a roller, sprocket, and an idler can be carried out smoothly, and the drive power can be transmitted sufficiently, and in particular, the generation of the slip of wheels can greatly be reduced.

Title: Semiconductor device having internal matching circuit
Inventor: NOGUCHI KAZUO
IPC: H01L23/66
Filed: 1979-03-23
Abstract: PURPOSE:To obtain a semiconductor device having an internal matching circuit which can be mass-produced, by employing a spacer to secure a space between a transistor chip and a capacity chip, whereby the scatter of a circuit constant can be reduced without increasing the cost of a case. CONSTITUTION:The positions of a transistor element 3 and a capacity element 7 are determined by a spacer 201. The spacer 201 consists of a dielectric of a low permittivity, and is provided on its one surface with metallized layers 202, 203. The metallized layer 202 is fixed to a grounding conductor layer 4, and the metallized layer 203 to a metallized layer 2 on a substrate 1. Owing to the use of such a spacer 201, the positions of the transistor element 3 and capacity element 7 can always be correctly set irrespective of the structure of a case and separation error of the metallized layers. Thus, a transistor device having no errors in the values of elements constituting an internal matching circuit can be mass-produced.

Filed: 1989-02-14
Abstract: PURPOSE:To convert a video signal into a video signal of the television standard system with simple circuit constitution by extracting the line information as to n-line among each line information of a video signal subjected to band compression. CONSTITUTION:The line information of a video signal is extracted for one line per 3 lines, for example, by a line number conversion function block 17a in a conversion circuit 17 to expand the time base of a line information signal extracted by a time axis conversion function block 17b. That is, the conversion circuit 17 extracts the information of one line among 3 lines of a television signal of a band compression transmission system to extract the information of 375 scanning line number in the scanning line number 525 of the NTSC system television signal to form a video signal corresponding to the NTSC system television receiver. Thus, in the case of converting the high resolution video signal subjected to band compression into the video signal of the television standard system, the system is converted easily with simple circuit constitution and high picture quality and roundness rate.

Abstract: PURPOSE:To prevent the generation of the revolution-disable-trouble of a roller by setting the height gap between the second cylinder and the second roller before the fastening fixation by the first and the second bolts, larger than the height gap between the first cylinder and the first roller. CONSTITUTION:Since the amount of reduction of the height gap (b) between the second cylinder 10 and the second roller 14 before and after the fastening fixation through the first and the second bolts 25 and 26 is larger than the amount of reduction of the height gap (a) between the first cylinder 3 and the first roller, setting is performed so that the gap (b) is made larger than the gap (a) before the fastening fixation. Therefore, after fixation is performed through the first and the second bolts 25 and 26, each gap (a), (b) is made nearly equal, and each gap (a), (b) secures the sealing effect by holding a proper oil film the both gaps (a) and (b), and the optimum gap for the smooth lubrication action can be set. Therefore, the prescribed refrigeration capacity can be obtained on the both of the first and the second cylinder 3 and 10 sides, and the revolution-disable-trouble due to the seizure, etc. of the rollers 6 and 14 can be prevented.
