Title: Title generator
Inventor: NAGAI TADASHI
IPC: H04N9/74
Filed: 1989-06-23
Abstract: PURPOSE:To prevent the color of a second title from being influenced by the color of a background by adding a first title with a trimming and a variable hue and the second title with the trimming and fixed hue. CONSTITUTION:For a first title signal 111 generated by a first title generating part 101, R, G and B title signals 115-117 corresponding to the R, G and B of chrominance signals, respectively, are generated by a hue control part 103 by hue control signals 112-114 from a hue generating part 102 and inputted to respective OR gates of a first logic part 105. To the OR gate of the first logic part 105, a second title signal 119 from a second title generating part 104 is commonly inputted. A first trimming signal 110 and a second trimming signal 118 generated by the title generating part 101 and 104, respectively, are inputted to the OR gate of a second logic part 106. Since only the first title signal 111 is inputted to the first logic part 105 through the hue control part 103, the hue of the first title can be made variable, and the second title is made to have the fixed hue.

Title: Equipment for cutting bead on welded pipe
Inventor: FUJIMOTO KUNIHARU
IPC: B23C3/12
Filed: 1984-07-31
Abstract: PURPOSE:To heighten the bead cutoff capability of an equipment for cutting a bead on an electrically welded pipe or the like, by inserting a tool pusher into the open steel pipe through between the opposed edges thereof, pushing a tool onto the line of the bead, and rotating a horizontal support bar around its axis. CONSTITUTION:The vertical adjustment mechanism 14 of a cutting tool pusher is operated to change the length of a securing rod 13 to vertically move it to displace a mandrel 9 up or down through a sleeve 12. A cutting tool 6 is thus pushed onto a bead Bi by an appropriate force. A support bar 10 is rotated around its axis by an electric motor 7 through a worm 16 and a worm gear 15 so that the tool 6 follows the bead Bi in its circumferential direction. According to this constitution, the cutting of the bead Bi can be continued while coping with the deviation in the position of the cutting tool 6 and with the change in the inside diameter of a bead-cut pipe. The bead cutoff capability is thus heightened.

Title: Semiconductor integrated circuit
Inventor: SUZUKI TAKAMASA
IPC: H01L21/822
Filed: 1986-07-11
Abstract: PURPOSE:To make it possible to quickly perform tests characterized by high fault detecting rate, by switching whether test signals are commonly supplied to functional blocks through a selecting signal generating circuit or to a specified block. CONSTITUTION:When a test mode signal is applied to a mode switching terminal 111, input switching circuits 140-142 of the same functional blocks 130-132 in a semiconductor integrated circuit 100 are switched. Thus an input from an ordinary input signal line 150 is cut OFF, and test signals are commonly inputted to the blocks 130-132 from a terminal 110. Thus the blocks 130-32 are tested. Meanwhile, when a selecting signal 171 is set through a selecting signal generating circuit 170, the block 131 keeps an output state, and the new testing signals are supplied to the blocks 130, 132 and the like. Thus said blocks are made to be the state different from the block 131. In this way the input pattern for testing can be made short, and the tests characterized by few erroneous operations and high fault detecting rate can be carried out quickly.

Title: Semiconductor laser element
Inventor: MORIMOTO TAIJI
IPC: H01S5/00
Filed: 1985-07-23
Abstract: PURPOSE:To obtain a semiconductor laser with a good controllability comprising a window region with small laser beam absorbtion capability, by forming grooves parallel to a resonating direction at a position of a base layer of an active layer which acts as a laser oscillation region in the vicinity of a resonator end plane and at a position away from the laser oscillation region and by laminating an active layer of the laser oscillation region thinly on the resonator end plane. CONSTITUTION:On the substrate 10, on which sub-stripe grooves 22a,...22d of larger shape than that of a main stripe groove 21 for laser oscillation are aligned in the vicinity of the end plane of a laser resonator, a multilayer crystal of semiconductor laser is formed using a liquid-phase epitaxial growth method. Consequently, the thickness of an active layer 13 on the main stripe groove involved with light emission changes along the laser oscillation direction and it becomes thinner near the resonator end plane and thicker in the excitation region inside the resonator.

Title: Electronic computer
Inventor: NISHIZAWA SHIGEYUKI
IPC: G06F3/023
Filed: 1989-06-26
Abstract: PURPOSE:To secure the interchangeability between the key input devices by using a controller which contains a signal conversion means and a means which transfers a code conversion table to the controller from an input device. CONSTITUTION:A main body 110 contains a CPU 111 and a RAM 112 which stores a code conversion table, and a keyboard 120 contains a CPU 121 and a ROM 122 which stores a code conversion table. When an initialization program is carried out, the CPU 111 sends an instruction to the CPU 121 for transfer of the code conversion table. Thus the code conversion table is sent to the CPU 111 from the RM 122 via an input/output device 130. Then the conversion table is sent to the RAM 112 and the CPU 111 converts an external code into an internal code by reference to the code conversion table. Thus it is possible to eliminate the non-interchangeability between the key input devices having different code conversion tables and to quickly cope with the change of the key input device.

Title: Shading correction method for optical line sensor
Inventor: KAMIOKA TADASHI
IPC: H04N1/40
Filed: 1990-06-21
Abstract: PURPOSE:To eliminate the need for a trouble of the operator for each correction by correction both shading correction information sets of transmission and reflection in the state of absence of a medium. CONSTITUTION:An optical line sensor consists of light emitting element sections 1a, 1b, light receiving sections 2a, 2b and a control section 5. The control section 5 measures shading information of a transmitted light by the light emitting element section 2a and the light receiving section 2b while no medium dp to be detected exists, calculates a characteristic change in the optical line sensor from the measured transmitted light shading information and the past transmitted light shading information and corrects the shading correction information of a reflected light through the use of the characteristic change. Since the measurement of the shading correction information of a reflected light is not required, a trouble of loading of the medium by the operator is saved.
