Title: Method for welding fixed tube
Inventor: YOSHINO FUMITO
IPC: B23K26/21
Filed: 1993-05-25
Abstract: PURPOSE:To provide a method for welding a fixed tube with a high speed and high efficiency. CONSTITUTION:In the first pass of the welding of fixed tubes which are butted in a horizontal or an inclined position, the southern hemisphere part of the circumference of the fixed tube is welded (A) from the inner surface side of the fixed tube, and the northern hemisphere part of the circumference of the fixed tube is welded (B) from the outer surface side of the fixed tube. When the welding from the inner surface side of the fixed tube is executed simultaneously with the welding from the outer surface side of the fixed tube, the welding efficiency is further improved. When the keyhole welding is executed with the plasma as the heat source, the welding efficiency is improved. After this first pass of the welding, the all position welding is executed on the inner surface and/or the outer surface of the fixed tube over the whole circumference of the joint. In the case of the plasma arc welding, it is preferable to provide a lap part to the first bead and the second bead. This welding method is suitable for the welding of the horizontal fixed tube of medium to large diameter.

Title: Boost pressure detection system with solenoid for purging
Inventor: MITANI TATESHIRO
IPC: G01L19/06
Filed: 1987-06-10
Abstract: PURPOSE:To enable accurate detection of operating condition of an engine in a normal engine operation environment, by providing a solenoid valve for purging to release a pressure in a hose to the atmosphere when an internal combustion engine is stopped. CONSTITUTION:In the stage of a normal operation, an ignition (IG) key is set to an IG terminal while a solenoid valve 32 for purging is energized through a connector 33. As a result, a nipple 34 on the side of an engine and a nipple 35 on the side of atmosphere are closed and a boost sensor 8 detects a pressure in an intake manifold 11. Moreover, condition of the solenoid valve 32 for purging remains unchanged during the operation of the engine and the boost sensor 8 continues to detect a pressure of the intake manifold 11. When an operator turns OFF a keyswitch to stop a vehicle, the energization of the solenoid valve 32 for purging turns OFF to separate the nipple 34 on the side of the engine and the nipple 35 on the side of atmosphere, and thus, the inside of the hose 30 is released to the atmosphere.

Title: Solid-state image pickup device and driving method
Inventor: KOBUCHI HIROTO
IPC: H04N5/355
Filed: 1993-06-17
Abstract: PURPOSE:To expand an incident light quantity handling range without causing color slippage and luminance deviation by eliminating the difference of storage periods in a second storage period. CONSTITUTION:An output signal charge amount obtained by read and transfer operations by mixing two picture elements in a conventional CCD is indicated as a conventional two picture element mixing type saturation charge amount 320 and a value to be approximately half the value of the charge amount 320 is indicated as a saturation charge amount 321 at the time of independently reading the entire picture elements. In this case, since signal charge for which even-numbered line second signal charge in the second storage period T2 and odd-numbered line second signal charge in the period T2 are mixed can be simultaneously and independently read, an electronic shutter two picture element mixing time saturation charge amount can be obtained. Since the period T2 can be changed from 1/500 to 1/2000 seconds for instance in this case, effect indicated by 'Variable' can be obtained. Thus, a handling incident light quantity expansion range larger than a conventional type handling incident light quantity upper limit 324 can be attained.

Title: Slice thickness adjusting method for magnetic resonance device
Inventor: KASUGAI TAKAO
IPC: G01R33/54
Filed: 1990-06-06
Abstract: PURPOSE:To easily obtain the cross section image of thin slice thickness by superposing two adjacent excitation surfaces and applying an excitation pulse. CONSTITUTION:Both excitation surfaces Sa, Sc have a superposed part, and are classified into the surface A by only the excitaion surface Sa, the surface B on which both the excitation surfaces are superposed, and the surface C by only the excitation surface Sc. When an excitation pulse is applied alternately in order of the excitation surfaces Sa, Sc, Sa... by such a pulse sequence as slace thickness becomes 'a', magnitude of an MR signal from the surface A is determined by a repeat time of Sa-Sa, and magnitude of the MR signal from the surface B is determined by a repeat time of Sc-Sa. When an application interval time of the excitation pulse is set uniformly, for instance, in the case of the pulse sequence of the excitation surface Sc, the repeat time of Sc-Sc becomes two folds of the repeat time of Sa-Sc. In such a way, at the time of photographing an MR image, the excitation pulse is applied so that the excitation surfaces are superposed, the repeat time is different in the right half and the left half of the excitation surface, that which is short in the repeat time can disregard the generated MR signal, and the MR image is obtained by slice thickness of thickness of half of the excitation surface.

Abstract: PURPOSE:To realize a large-capacity memory small area, by forming longitudinal grooves with octagonal opening parts on a substrate and forming four separate capacitors on four wall surfaces provided with dielectric isolation. CONSTITUTION:Grooves 11a, 11b,... with octagonal opening parts are formed on a P type silicon substrate 10, and the grooves are filled with polysilicon electrodes 13 which are made of silicon oxide as dielectric of a capacitor and formed on insulation films 12a to 12c.

Abstract: PURPOSE:To omit the hardware parts by using the software of a microprocessor to perform a filtering process without adding any filter circuit of hardware to an input circuit. CONSTITUTION:A periodical signal generating circuit 2 is used to produce the interruption signals for each fixed time together with an input circuit 7 which receives the input signal from outside, and a filtering process means which reads the signals out of the circuit 7 for each fixed time and filters them. A microprocessor 1 reads the signals out of the circuit 7 for each fixed time and filters and fetches them as the signals to be processed. Thus no hardware filter is needed and the filter time constant can be changed by a program since the filtering process is carried out by the microprocessor 1. Furthermore the filter time constant can also be changed for each signal.
