Abstract: The present invention provides eRF3 proteins capable of prionizing heterologous eRF3 proteins, and eRF3 proteins capable of being prionized by heterologous eRF3 proteins. Using these proteins, screening for substances that inhibit transmission of abnormal PrP, detection of abnormal PrP, creation of abnormal PrP, and screening for substances that restore abnormal PrP to normal PrP are carried out.

Abstract: A press forming die is fabricated by initially fabricating a die forming panel, by press forming, which provides a die surface for the press forming die. During fabricating the die forming panel, a shaped panel is obtained by initially press forming a first blank material with a die forming prototype and a punch forming prototype. Next, the shaped panel is mounted onto the punch forming prototype again and, thereafter, a die forming panel is obtained by press forming a second blank material. The die forming panel is then mounted on a frame body and a backup material is formed between a space between the frame body and the die forming panel, thereby fabricating the press forming die. Since the die surface of the press forming die can be shaped by press forming, the press forming die can be simply fabricated.

Abstract: An economical method of producing a press-forming die is disclosed wherein a master die and a master punch are relatively reciprocated with a full stroke and a shorter stroke to produce a press-formed panel and a half-pressed panel. After an elastic material is applied to one surface of the half-pressed panel, the press-formed panel is fitted over the master punch, and the half-pressed panel is forced against the press-formed panel with the elastic material facing away from the press-formed panel, whereby the half-pressed panel is shaped into a die panel complementary in contour to the shape of the press-formed panel. A back-up material such as high-strength cement is then applied to the rear surface of the die panel whereby a press-forming die is produced.

Abstract: An economical method of producing a press-forming die is disclosed wherein a master die and a master punch are relatively reciprocated to produce a press-formed panel. A working surface of the master die is cut down by a predetermined cutting depth, and the press-formed panel is fitted over the master punch. While a second blank sheet having a thickness equal to the cutting depth of the master die working surface is placed between the master die and the press-formed panel fitted over the master punch, the master die and punch are relatively reciprocated whereby the second blank sheet is press-formed into a die panel. A back-up material such as high-strength cement is then applied to the rear surface of the die panel whereby a press-forming die is produced. A method of producing a press-forming punch is also disclosed.

Abstract: A high pressure fuel injection system for an internal combustion engine having a high pressure pump for delivering fuel to a fuel injector. The pressure output of the pump is sensed and is controlled to provide appropriate fuel pressure to the fuel injector for the given running condition. In addition, a release passage is formed that intersects the high pressure pump at a point intermediate the ends of its stroke and which is controlled by a control valve for releasing pressure to further provide pressure control. Even if fully opened due to failure, the release valve will not preclude the generation of pressure sufficient to run the engine.

Abstract: A zoom finder includes a finder optical system in which at least one lens group is moveable in the optical axis direction thereof to perform the zooming operation; a guide shaft which extends in parallel with the optical axis; a lens mount member which supports the movable lens group and through which the guide shaft extends to support the lens mount member to move in the optical axis direction; and a drive cam which is rotatably supported by the guide shaft, so that the lens mount member moves in the optical axis direction in association with the rotation of the drive cam.

Abstract: A body structure of a camera having a film cartridge chamber which as a whole is formed in the shape of a hollow cylinder and has an opening/closing lid at an axial end portion thereof. The hollow cylindrical film cartridge chamber is formed by a camera body and a rear cover which is formed separately from the camera body and is secured to a rear of the camera body. The outer appearance of the camera is formed by an outer surface of the rear cover. It is possible to make the camera further compact.

Abstract: A golf swing training device actuated by golf club back swing and down swing by the golfer and comprising arm angle detecting means which includes a support member mounted on a golfer's arm for movement therewith as the golfer makes a swing, a direction indicator mounted on the support member and for indicating a direction in a plane including the gravitational direction or a direction at a fixed angle to the gravitational direction, and a direction indicator detecting means for detecting the direction indicator when an angular position set as desired with respect to the direction indicator is reached by the support member, and a means for informing the golfer of the arm angle detected by the arm angle detecting means through the controller. The informing means including means for initiating a signal and transmitting such signal to the golfer or knee, waist and/or ankle of the golfer for causing slight twisting of the golfer's body in a down-swing start direction and starting down swing.

Abstract: When the golfer makes the most important part of the golf swing, i.e., from the back swing to the down swing, most of the movements of swing check points after the top naturally become good by performing an ideal body turn of lower body lead. It is intended to permit such an ideal body turn to be mastered, eliminate a commonly termed hand shooting from the top, increase the head speed without irrational force to increase the distance, improve the shot control and produce high level swing form. To realize these intents, a golf swing training device 10 was constructed with detecting means 12 for detecting the contact of the golfer's shoulder with the chin or close contact of the former to the latter at the time of the back swing, and notifying means 20 for providing a detection signal to the golfer 18 via a controller 16, and transmitting means 22 and 24 for transmitting to the waist or knee. Further, second detecting means are provided, if necessary.

Abstract: A data recording and/or reproducing apparatus records and/or reproduces data and data management information corresponding to the data on helical recording tracks. It can be feasible to detect the use of the helical record tracks in reproducing and immediately access the recorded data, the data record region and the data management region in recording or reproducing.

Abstract: A data recording and/or reproducing apparatus records and/or reproduces file data by processing the file data on the unit of a predetermined block length, a data block and information data for identifying the data block on predetermined unit regions. A supplement data is recorded on a region other than the region recorded the file data, the block data and the information data for identifying within the unit regions. Thereby these data are recorded and/or reproduction processed at every predetermined units so that the bit error rate is remarkably improved.

Abstract: A process for producing a pitch which is used as a raw material for producing carbon fibers is disclosed. The process comprises subjecting a petroleum heavy residual oil to hydrogenation treatment in the presence of catalysts, removing a low boiling point fraction of the oil by reduced pressure distillation, subjecting the resulting reduced pressure distillation residual oil to solvent extraction treatment, and carrying out thermal modification of the resulting extraction component.By utilizing the process for producing the pitch it is possible to use a wide variety of different types of oils in order to produce carbon fibers. The carbon fibers produced from the pitch produced according to the disclosed process have desirable characteristics.

Abstract: In a motor control system including a clock pulse generator, use is made of the clock pulses for deriving digitally, the speed-above-normal signal, the starting signal, the brake-release signal and the normal or forward rotation signal for displaying the normal or forward rotation. In response to the starting signal, 100% torque control voltage is generated and in case of the forced reversal in rotation, 100% torque control voltage for preventing the rotation in the reverse direction is generated.
