IPC: F01M9/10
Filed: 1982-02-01
Abstract: PURPOSE:To form a pipe material to less thickness and less diameter, by both decreasing length and weight of a pipe supplying lubricating oil to a cam shaft  of a DOHC internal-combustion engine and increasing strength and rigidity of  the pipe with a common supporting member. CONSTITUTION:A piping unit 18 consists of almost parallel two supply pipes 19 extended in the direction almost at a right angle for two cam shafts and communication pipe 20 linked in such a manner as to connect intermediate parts of the pipes 19 and located in parallel to the cam shafts. The pipe 20 communicates a passage 19a in the pipe 19 by a passage 20a in the inside, and mounting bases 21... are equipped respectively in front and rear ends of the pipes 19, 19, then the passage 19a is communicated into the base 21.

Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/32
Filed: 1993-02-02
Abstract: PURPOSE:To suitably distribute received information by refusing reception from parties excepting for the party, for which communication error is generat ed, when the error is generated. CONSTITUTION:When the communication error is generated, first of all, a transmitter informs of it to the receiver on the after end at the time of pre-procedure. When it is informed from the transmitter that the retransmission from the error generating page is enabled at the time of generating the communication error, the receiver does not record the error page in the middle of communication but refuses the reception excepting for the retransmission from the party generating this error and the error generating page of the same party for prescribed time in the case of generating the error in the middle of communication. When the retransmission from the error generating page is performed, this is reported from the transmitter to the receiver by a procedure signal. This control is performed by a control circuit 40. Thus, the information can be continuously recorded on the side of the receiver without recording the other received information during the reception, and a user can suitably distribute the received information.

Title: Magnetic tape cartridge
Inventor: MORITA KIYOO
IPC: G11B23/107
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent entry of dust from an aperture to inside of cartridge when a cartridge is not used by bending, at the right angle to the moving direction of the slide door, the end portion of the contact area to the aperture of the slide door for opening and closing the aperture for leading the tape. SOLUTION: To assure the opening operation of a slide door 3 in the tape leading mechanism of a drive when a magnetic tape cartridge is set to a drive, the end portion in contact with the aperture for leading the tape of the slide door 3 is provided in the moving direction of the slide door 3 and the L-shaped member 6 bending at the right angle to the moving direction is formed. Thereby, the area of the contact surface 3 may be provided widely. Accordingly, entry of dust when the cartridge is not used and moreover rotating space of rotatable rid in the device side is unnecessary. In addition, since the slide door 3 is held in the closing position when cartridge is not used, the rotatable rid for opening and closing the aperture for leading the tape is not required at the time of leading the tape and thereby rid lock canceling operation becomes unnecessary.

Title: Burner
Inventor: NAKAJIMA AKIHIKO
IPC: F23D11/24
Filed: 1983-02-01
Abstract: PURPOSE:To attain shortening of flame length, stabilization of flame and reduction of combustion sound by the operations to promote the fine division, despersion and mixture of the fuel, by providing an inverse conical evaporating cylinder and air holes formed by a simple punching operation at the side wall of the evaporating cylinder. CONSTITUTION:When fuel is ignited by an igniter 9, the fuel receives air in a large quantity which is supplied for fine division, and is instantaneously and completely burnt. More specifically, since an evaporating cylinder 1 has an inverse conical shape, air supplied to the fuel group to be sprayed is supplied downwardly. Since air holes 2 provided for fine division are directed downward, the evaporating cylinder 1 has smaller diameters at the lower parts and larger diameters towards upper parts, and further an auxiliary combustion cylinder 5 is provided upright with the same diameter, with respect to the evaporating cyliner 1, the auxiliary cylinder 5 is relatively throttled toward the upward. Hence, in an evaporating chamber A the mixing operation is promoted, and at the parts above the tip end of the auxiliary cylinder 5 the gaseous mixture is effectively supplied to the evaporating cylinder. Therefore, fine division, dispersion and mixing are promoted at parts of air holes, and stable blue flame 14 is formed by the downward air injection.

Title: Majority circuit
Inventor: OUCHI NOBUAKI
IPC: G06F7/76
Filed: 1986-01-29
Abstract: PURPOSE:To decrease the number of a comparator necessary for comparing the data and to facilitate a circuit by inputting NC2 pieces of the data assembling to the comparator and selecting the most data mutually equal from N pieces of the based upon the stored comparing result. CONSTITUTION:By circulating the data in N pieces of a data register 10 by a data circulating means, two different assemblies of the data successively appear at the output of two different registers of the N pieces of the data register 10 and compared by a comparator 17. Since the comparing result by a comparator 17 is stored to a comparing result register 18 by matching to a data circulating timing, the most data mutually equal from the N pieces of the data can be selected by the output of the comparing result register 18. Thus, the number of the comparator may be M pieces which can obtain NC2 pieces of the assembly concerning the data during the circulation, the M is much smaller than the number NC2 of the comparator needed in the conventional majority circuit and the wide facilitation of the circuit can be executed.

Filed: 1982-02-05
Abstract: PURPOSE:To perform the positioning with high accuracy and a high speed, by projecting parallel beams from a parts lead and one side of a substrate and forming the silhouette image to an image pickup means via an optical means set at the opposite side. CONSTITUTION:A printed substrate 2 on an X-Y-theta table 1 is irradiated by the parallel beams from a projector 4. Then the silhouette of a lead mounting pad 3 on the substrate 2 is formed to TV cameras 8 and 18 via an optical system containing an image forming lens 5 and reflectors 6 and 7. The cameras 8 and 18 give a raster scan to the silhouette image and transmit picture signals to a deciding circuit 20 via a binary coding circuit 19. The circuit 20 calculates the position shift of the silhouette in X, Y and theta directions respectively. Based on this calculation, the position shift of the pad 3 due to a shift of a flat bag parts 10 which is produced by a parts transporting arm 14 is calculated to feed the position compensation quantity to a positioning control circuit 21.

Abstract: PURPOSE:To obviate generation of a fluctuation in the adhering and fixing state of joint surfaces owing to a temp. change, a change with lapse of time, etc. by forming one face of at least one prism among the faces of each prism except the joint surfaces in such a way that the plane inclusive of said face does not intersect with any faces of the prisms. CONSTITUTION:A compound prism 40 can be stably fixed by positioning and fixing the bottom face 402 of the other rectangular prism 400 as a fixing face to a mounting base plate 20. A space S1 exists between the bottom face 302 of one rectangular prism 300 and the plate 20 and since the contact between the prism 40 and the plate 20 is made only on the bottom face 402 of the other rectangular prism 400, the force in the face direction is not generated between slopes 301 and 401 which are the joint surfaces of both rectangular prisms 300 and 400. The angle between the photodetecting surface of a photodiode and the optical axis of incident light is always maintained constant and the device operates normally without fluctuation in the adhering and fixing state of the slopes 301, 401 owing to a temp. change, a change with lapse of time, etc.
