Title: Toroidal type continuously variable transmission
Inventor: OGOSHI HIDEO
IPC: F16H37/02
Filed: 1987-12-24
Abstract: PURPOSE:To promote the improvement of fuel consumption substantially decreasing a power loss in a torodial type continuously variable transmission by providing the toroidal type continuously variable transmission and a planet gear mechanism, consisting of two sets of planetary gears, to be arranged between input and output shafts. CONSTITUTION:The first power transmitting mechanism 22A is actuated, and by fixing a ring gear 28 of the first planetary gears 21A by a clutch 35, a toroidal type continuously variable transmission 10 transmits rotary driving power of its output disk 16 to an output shaft 34 so that it reversely rotates to an input shaft 12, obtaining the first mode in an advance condition. In this mode, placing the transmission 10 in a maximum accelerating position and the first power transmitting mechanism 22A in an inoperative condition, the second power transmitting mechanism 22B is actuated, when a ring gear 33 of the second planetary gears 21B is fixed by a clutch 42, the second mode in an inverse power generating advance condition, transmitting rotary driving power of the input shaft 12 not through the transmission 10 but directly to the output shaft 34 while returning one part of the power to the input shaft 12, is obtained. In this way, power loss can be decreased.

Title: Facsimile equipment
Inventor: AZUMA MASATO
IPC: H04N1/21
Filed: 1989-12-20
Abstract: PURPOSE:To easily grasp the outline content stored in a storage means by outputting information in a designated area by a selection means among information stored in the storage means without reduction. CONSTITUTION:The information received in a storage means 26 is stored while an identification symbol such as a file number or a page number is stored, and information in an optional area among information stored in the storage means 26 is selected by a selection means 16. The selection is implemented by selecting a factor such as a file number, a page number or an output area, and an output means 20 outputs the information in the area selected by the selection means 20 onto recording paper. That is, when the selection means gives a command of, e.g. outputs of several lines from the top line of a top page of each file, the commanded information is continuously outputted onto recording paper. Thus, even when the stored information is huge in its quantity, the outline content of each file is easily grasped.

Title: Twist drill
Inventor: KONDO TATSUO
IPC: B23B51/00
Filed: 1991-11-15
Abstract: PURPOSE:To improve work efficiency by gravenly providing a small groove on a land part along a margin to dispense with such an operation as a drill is drawn out during drilling process to pour a cutting oil on it. CONSTITUTION:A small groove 22 is formed on the portion of a land 18 along the margin 16 of a twist drill. In this case, the small groove 22 continues along the margin 16, and its tip extends to the portion of a cutting edge 12 at its tip, and its rear end extends to a neck 24 being thin in diameter. After a cutting oil is supplied into the small groove 22 and drawn to the inner part as drilling work using the drill is executed, the cutting oil passes through the small groove 22 together with a chip to go out of the twist drill. Since the cutting oil is abundantly supplied in this way, the cutting resistance of the drill does not increase so, and the narrow width of the margin 16 is therefore applicable to the drill, and cutting performance is improved, and the lowering of strength does not occur.

Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the performance by forming a data track in a spiral state with the use of the servo area arranged in the peripheral direction of a disk at every specified space and unnecessitating the seek operation for the movement between tracks in the reading/writing operation for continued data. SOLUTION: The constitution is made in such a manner that the target value of a PES(position error signal) obtained from servo signals which are buried on the track with the specified spaces, is successively changed for realizing the spiral track by reading the PES which is the conventional servo information. In the case of the disk device performing the positional control with the PES obtained from each servo area in the disk which is provided with the servo area of 60 pieces per one round of the disk, when the values available for the PES as the information on each position in the width direction of one track are taken as 256 kinds, the positional control of the head is executed by the value set by succesively shifting the target value of PES for every 256/60 track position in each of 60 servo positions.  By such a positional control, the head is moved in accordance with the target PES values different for every servo area, thereby, the spiral track is followed up.

Filed: 1989-12-20
Abstract: PURPOSE:To enable an emitter mesa to be formed without causing a mask of etching to be peeled off in a fine emitter pattern by forming one part of the emitter mesa by dry etching and by performing dry etching vertically to the emitter mesa when forming the emitter mesa of HBT. CONSTITUTION:When forming an emitter mesa of a hetero junction bipolar transistor(HBT), a sample where an emitter mask 11 which also plays a role of an emitter electrode is dry-etched to an emitter contact layer 12 and an emitter layer 13 by RIE using a CCI4l7 as an etching gas. Further, by performing dry etching of this sample vertically for the emitter mesa with RIE using a CCI4100, the emitter mesa is completed. Thus, it becomes possible to form the emitter mesa without causing the etching mask 11 from being peeled off the emitter contact layer 12 even in a fine emitter pattern. Further, a base electrode 18 can be formed in self-aligned manner by the vacuum deposition method with the emitter electrode 11 as a mask.

Title: Roll conveyor for carrying
Inventor: CHIBA HIROO
IPC: B65G17/24
Filed: 1988-12-26
Abstract: PURPOSE:To prevent the wear of an attachment, a plate, a pin, and a roll of a driving chain by providing a supporting roll, whose diameter is smaller than that of a carrying roll, at one or two places on a carrying roll shaft and providing a supporting rail underneath the supporting roll. CONSTITUTION:A supporting roll, whose diameter is smaller than that of a conveyor roll 1, is placed at one or two places on a shaft of a conveyor roll 1, while a supporting rail 8 is placed underneath the supporting roll 7. In addition, a bearing is inserted between the supporting roll 7 and the shaft of the carrying roll 1 and fixed by a retaining ring. The reason why the diameter of the supporting roll 7 is made smaller than that of the carrying roll 1 is that, when an article to be carried is accumulated on the roll 1, although the carrying roll 1 moves under the article, rotating in the reverse direction, the supporting roll 7 moves in the same direction as that of a roll 4 of a driving chain. With this contrivance, the load of the article to be carried is not applied to the driving chain, and consequently the wear of an attachment 2, a ring plate 3, a pin 5, and a roll 4 can be prevented.
