Title: Exhaust manifold of internal combustion engine and manufacture thereof
Inventor: WATANABE YOSHIMASA
IPC: F01N13/18
Filed: 1994-06-16
Abstract: PURPOSE:To prevent the occurrence of a thermal fatigue crack in an exhaust manifold and improve the reliability and heat resistance of the exhaust manifold at a low cost by dispersing distortion concentrated to a part of the exhaust manifold. CONSTITUTION:Exhaust gas flowing in from two ports 4a, 4d and 4b, 4c of an intake side flange 4, is respectively collected, and introduced to the parts 5a, 5b of an exhaust side flange 5. An exhaust manifold 3 is formed by making an upper side manifold 1 and a lower side manifold 2 abut on each other and mutually welding their gills 6. The expansion/shrinkage of the exhaust manifold 3 is repeated in such a way that the exhaust manifold 3 is heated by exhaust gas during the operation period of an engine so that the whole exhaust manifold 3 is thermally expanded, and cooled during the stopping period of the engine so as to be shrunk. As a result, a crack easily occurs to the root parts of the gills 6 in such parts as easily receiving thermal fatigue like the inner sides of curving parts 7, etc. Therefore, heat treatment is applied to parts close to the inner side parts of the curving parts 7 or the inner side parts of the collection branch parts of a pipe. Hereby, thermo-plastic distortion is dispersed.

Inventor: OKI KIKUO
IPC: G03G21/00
Filed: 1985-06-21
Abstract: PURPOSE:To prevent the emission of light without an original by shifting light a shielding sheet by a specified distance in the direction in the area of an original, detecting the presence absence of an original by sensors there, and prohibiting the exposure of copying operation if the presence of the original is not confirmed. CONSTITUTION:When image forming the area of exposure by light shielding sheets 3a, 3b, pulse motors 6a, 6b are controlled basing on detection signals from each presence absence of original detecting sensors 5a, 5b. When the edges of orthogonal directions of an original 2 placed on a platen 1 are detected by the presence of original detecting sensors 5a, 5b, the moving of light shielding sheets 3a, 3b is stopped. Pulse output generated in encoders Ka, Kb is given to a controlling section and used for detection of the size of the original, and at the same time, the light shielding sheets 3a, 3b are shifted once to the end of the original. Before making a copying operation, these are returned a little by a specified length, and the presence of the original on the platen is reconfirmed. On detecting that the original is not removed and exists on the platen surely, the copying operation is permitted.

Title: Ion implantation method
Inventor: TANAKA TOSHIHIKO
IPC: H01L21/265
Filed: 1993-06-04
Abstract: PURPOSE:To avoid halation and realize highly accurate ion implantation to form a fine pattern by a method wherein an organic film which absorbs an exposure light is formed on a substrate, a resist pattern is formed on the organic film and required ions are implanted without processing the organic film. CONSTITUTION:An element isolation oxide film 2, an oxide film 3 and a polycrystalline silicon film 4 which is a gate are formed on an Si substrate 1 to obtain an MDS-FET structure. Then an organic film 5 which absorbs an exposure light for pattern exposure is formed by coating and heat treatment. Then a resist pattern 6 is formed by resist coating, exposure and development. After that, ions are implanted 7 to form an ion implantaion layer 8. After that, an ordinary plasma treatment is performed and the light absorbing organic film 5 is removed with the resist to form an offset gate MOS-FET. As the ions are implanted into the required positions of the obtained MOS-FET, required electrical characteristics can be obtained. With this constitution, halation can be avoided, so that this ion implantation method can be applied to the formation of a fine pattern.

Abstract: PURPOSE:To prevent the breakage or display defect of an LCD panel which is caused when a load is applied on a personal computer main body by placing an elbow, etc., carelessly on a closed LCD display part by arranging a rib, a recessed part, etc., on an outward case. CONSTITUTION:The back 2 of the outward case has the recess 3 provided on the inside surface and the rib 4 provided on the inside surface.

Title: Three-phase ac power supply open-phase detection apparatus
Inventor: WATANABE JIRO
IPC: H02H3/34
Filed: 1994-05-25
Abstract: PURPOSE: To miniaturize the constitution regardless of the capacity of the machinery connected to a power supply and to inexpensively produce an apparatus by connecting a bi-directional photocoupler across the wires of a three-phase AC power supply. CONSTITUTION: Bi-directional photocouplers 4, 5 are respectively connected across the R-, S- and T-phases of a three-phase AC power supply on the opposite side of the resistors 1, 2, 3 connected to the respective phases. When the line voltage of the three-phase AC power supply exceeds a threshold voltage, the LEDs of the photocouplers 4, 5 emit light to set phototransistors on a light detection side to an ON-state and the output signal to a CPU 7 becomes Dc voltage +V. The LEDs emit no light when the line voltage is in the vicinity of a zero cross point and the phototransistors become an OFF-state and the output signal to the CPU 7 becomes earth potential. When the respective phases R, S, T are in a normal state, either one of the phototransistors of the photocouplers 4, 5 is turned on and, therefore, the output to the CPU 7 is always DC voltage +V.  At the time of an open phase state, the output to the CPU 7 becomes earth voltage intermittently.

Title: Printing device for booklet
Inventor: MINEMATSU NOBUO
IPC: B41J2/51
Filed: 1979-10-22
Abstract: PURPOSE: To eliminate uneven printing by a method wherein the right end part of the booklet is printed by a stroke moving to the right in the reciprocating movement of a printing head, while the left end part is printed by a stroke to the left, and thereby the acceleration period of a motor in the end part area is removed.  
     CONSTITUTION: The printing head 1 is in a turnout position P 1  before the start of printing. When a printing instruction is given, the printing head is moved at a speed v 1  by the pulse motor. When the head comes to a point Q 2 , the speed of the pulse motor is reduced, and when it comes to a point Q 3 , the printing head is made to advance to a printing position P 2 , the speed of movement is accelerated up to the rate v 2 , and the printing is started from the point Q 4  where the acceleration is finished. When it comes to a position Q 7 , the printing head is lifted, moved to the left and performs the same operation as in the above. Since the printing operation is performed in the process of movement of the dot printing head from the center of the booklet toward the end part thereof in this way, such an operation as making the dot printing head be retreated in the turnout position beforehand is excluded, whereby the printing with a fixed printing quality throughout the booklet can be performed.

Abstract: PURPOSE: To make possible accurate non-contact measurement of shaft torque by so correcting the output of a torque gauge element applying magnetostriction as to eliminate variations with an arithmetic circuit based on the displacement gauge output by the variations in the spacing between the revolving shaft and element.  
     CONSTITUTION: A torque gauge element 2 is opposedly provided near the peripheral surface of the revolving shaft 1 to be measured and a displacement gauge 3 which converts the variations in the opposing spacing between the element 2 and revolving shaft to electric signals and outputting the same is secured to the side part of the element 2. The output of this displacement gauge 3 and the output of the element 2 are inputted to an arithmetic circuit 4, which in turn so corrects the output of the element as to be removed of the output variations owing to the variations in the opposing spacing based on the output of the displacement gause 3. Hence, the torque of the shaft 1 may be measured in the absence of contact, and since the output variation components of the element 2 are removed by the circuit 4 despite a change in the spacing between the revolving shaft 1 and element 2, the true torsional magnetostriction quantity produced in the surface of the revolving shaft 1 may be picked up and the magnitude of the torque acting upon the revolving shaft 1 may be accurately known.
