IPC: B23Q17/20
Filed: 1989-12-18
Abstract: PURPOSE:To eliminate the influence of deformation, waviness, vibration, etc., on a guide surface and to execute the measurement with high accuracy by deriving the increase ratio of a pitching motion at the time of moving a displacement detector fitting base by an arithmetic processing from a measured value by a roll profile measuring displacement detector at the time of measuring a roll whose roll profile shape is known. CONSTITUTION:A displacement detector fitting base 4 is moved in the axial direction of a work roll 2, and by displacement detectors 103a, 103b, 103d, 103f and 103g, a partial roll profile of the roll 2 is measured. In such a case, the measurement obtained from each detector comes to that which is obtained by superposing the relative displacement between the roll 2 and the fitting base 4 caused by a motion error at the time of moving a true roll profile and the fitting base 4 and vibration generated in the course of measurement. Accord ingly, a moving amount of the fitting base 4 is made larger than installation intervals l1 - l4 of the displacement detectors so that partial roll profiles mea sured by each displacement detector overlap. Also, by evaluating correctly the motion error and the relative displacement at the time of moving the fitting base 4, each measured value of the displacement detectors is corrected.

Title: Manufacture of bipolar transistor
Inventor: KOJIMA MANABU
IPC: H01L29/73
Filed: 1991-12-11
Abstract: PURPOSE:To enable parasitic capacity between a base and a collector to be reduced by reducing dimensions of an element region as compared with those of an emitter opening. CONSTITUTION:An opening which is provided to allowing a single crystal S1 layer to be subjected to epitaxial growth is reduced by forming a sidewall inside, thus enabling an emitter opening which is limited by it to be smaller than an element region and preventing it from being out of the element region. An emitter 20 which is formed due to introduction of impurities from the opening is not located outside a base region of a single crystal and a transistor structure is established. A dimension WB of the element region can be reduced to a degree where the alignment accuracy of lithography is added to the minimum value of WE which is generated due to restriction in terms of a wafer process, thus enabling electrostatic capacity between the base and the collector to be reduced drastically.

Title: Hot water and cold water mixing device
Inventor: NAGAOKA YUKIO
IPC: F16K31/66
Filed: 1989-12-18
Abstract: PURPOSE:To compound an automatic pressure adjusting valve and a temperature adjusting valve, to miniaturize the device and reduce the cost by a method wherein a variable operating force generating means is provided with an AC signal generating means for overlapping the alternative operating forces and then the alternative operating forces are reduced near a full-open state of a hot water side valve or a cold water side valve. CONSTITUTION:A control device 18 includes an AC signal generating means 18a. A signal from the AC signal generating means 18a is supplied while being overlapped with a coil current. An alternating operating force is given to the variable operating force generating means 19 with this AC signal. The valve is slightly vibrated with the alternative operating force so as to prevent a reduction of a frictional force or an adhesion of scale. As an electrical current from the control device 18 to a coil 21 is increased, a downward-directed force is strongly generated at an iron core 20 so as to cause the automatic pressure adjusting valve 3 to be biased downwardly. As a result, a cold water side is closed and a hot water side is opened, and each of the hot water side valve 4 and the cold water side valve 6 is varied and acts as the automatic pressure adjusting valve 3 to make a well-balanced state. As a result, a temperature of the mixed hot and cold water is increased. As an electrical current in the coil 21 is reduced, a downward-directed force in the iron core 21 is decreased so as to cause the automatic pressure adjusting valve 3 to be moved upwardly under a force of a main spring 24 and then the water side valve is opened and the hot water side valve is closed.

Filed: 1987-12-25
Abstract: PURPOSE:To judge the presence of cracking, by measuring potential differences in two directions orthogonal to each other at the same point on the surface of a member to compare both voltage differences. CONSTITUTION:A probe 4 is equipped with two sets of terminals (feed terminals 7 and 7' and detection terminals 8 and 8'), four per set. The terminals 7 and 7' and 8 and 8' are connected to a constant current device 2 and a fine voltmeter 1 respectively through a switching circuit 3. With such an arrangement, first, a potential difference (V) is measured between the terminals 8 and 8 with energization between the terminals 7 and 7. Then, a potential difference (V') is measured between the 8' and 8' with energization between the terminals 7' and 7'. Normally when a fine cracking is generated in a member, current detours around the cracking so that the potential difference increases as compared with a case having no cracking. Thus, when there is no cracking, V V' and when there is any cracking, V>V' or V<V'. This enables detection of the presence of a fine cracking.
