Title: Method for measurement of contact angle
Inventor: KISHI NOBUYUKI
IPC: G01N13/02
Filed: 1980-10-30
Abstract: PURPOSE:To measure the contact angle of liquid with a solid surface easily and accurately by irradiating a laser beam to a solid-liquid contact part, magnifying the contact angle by the reflected light thereof and measuring the same. CONSTITUTION:A liquid drop 2 of liquid sample is formed on the surface of a solid sample plate 1, and the laser beam 4 emitted from a laser device 3 placed in front of the plate is irradiated to a solid-liquid contact part in a way as to parallel to and contact the surface of the plate 1. If a screen 5 perpendicular to the beam 4 is placed behind the plate 1 and the beam is projected thereon, the image 6 of the liquid drop 2 and the image of the laser beam reflected by the surface of the drop 2 are obtained on the screen 5. The angle alpha that the side edge part 7 of the image of  the reflected laser beam and the surface of the plate 1 form is measured and from  (theta= 90 deg.C-alpha), the contact angle theta is determined.

Abstract: PROBLEM TO BE SOLVED: To maintain the same temperature as that during ordinary operation of each part even when a temperature rise process is repeated by providing a control means to decide operation of a cooling fan based on the input from a temperature sensor at the initial stage or during the starting of disposal after suspension of the disposal. SOLUTION: A control means 29 performs decision of the initial temperature according to temperature information from a temperature sensor 26. When temperature information is below 100 deg.C, it is decided that the temperature of a dry heater 28 is prevented from sufficient rise, and at a preliminary heating process, a cooling fan 25 is brought into an OFF-state and control is effected such that the temperatures of a drying heater 23 and a catalyst heater 28 rise rapidly. When it exceeds 100 deg.C, after suspension of disposal, it is decided that temperature inside the body 21 sufficiently rises, and a cooling fan 25 is turned on from the initial stage even when the body is in a preliminary heating process, the cooling fan 25 is turned on and operation is effected such that cooling of the interior of the body 21 is performed.  Thus, even when disposing is not suspended, even at re-disposal after suspension, optimum cooling corresponding to the situation is made on the interior of the body 21.

Abstract: PURPOSE:To support the rotation in a speed region from a low speed to a high speed, by constructing a bearing device from a rolling bearing and a hydrostatic air bearing arranged in an axial direction of a spindle, and making a rolling element and a race of the rolling bearing axially separatable from each other. CONSTITUTION:At low-speed rotation, a pressure oil is supplied from a pressure oil supply passage 21 to a cylinder chamber 19 to move a movable sleeve 16 in an axial direction of a spindle 11 and thereby make a rolling element 15a of an angular contact ball bearing 15 contact under a predetermined pressure with an inner race 15c. Accordingly, the spindle is rotatably supported by the ball bearing 15 to obtain a high bearing rigidity. At high-speed rotation, the pressure oil in the cylinder chamber 19 is released, and the movable sleeve 16 is moved by a spring 18. As a result, the rolling element 15a and an outer race 15b of the ball bearing 15 are separated from the inner race 15c. At the same time, a compressed air is supplied from a supply opening to a gap 23 defined between a bush 22 at the outer circumference of the spindle 11 and an inner circumferential surface of a housing 17, thus forming a hydrostatic air bearing at the gap 23 and permitting the high-speed rotation.

Filed: 1986-06-30
Abstract: PURPOSE:To obtain a current supply recording apparatus capable of obtaining stable and uniform printing density, by a method wherein a large number of electrode needles are divided into small blocks and time sharing driving is performed at every small block and the width of a current supply pulse or the number of said pulses is made variable corresponding to the number of the electrode needles.

A current supply pulse with (t) is changed at every block and the length thereof is determined by how many electrode needles among 16 simultaneously receive the supply of a current. For example, when a current is simultaneously supplied to 16 electrode needles 1, a current is supplied at a pulse width of T/3 and, when a current is supplied to only one electrode needle, a current is supplied at a pulse width of T/6 and, by this way, when the pulse width (t) of a current supplied is set so as to become longer as the number of the electrode needles increase, a dot having definite density or a stable size is obtained regardless of the number of the electrode needles 1 simultaneously receiving the supply of a current.

Title: Vertical magnetic head
Inventor: MATSUMOTO TAKAYUKI
IPC: G11B5/127
Filed: 1985-07-11
Abstract: PURPOSE:To improve the recording/reproducing efficiency and to reduce the inductance with a vertical magnetic head by forming a magnetic core of an energizing winding with a metallic magnetic thin piece having high permeability for application of the winding and at the same time attaching a member close to the magnetic core in a body for reinforcement. CONSTITUTION:An E-shaped core is obtained by supplying some cuts to a part of an amorphous metallic thin piece and an energizing winding 8 is applied to the core with the center projection defined as a magnetic core 11. While a U-shaped ferrite is obtained by cutting the plate type center part in order to evade the winding 8. Thus a reinforcement member 12 serving as an auxiliary magnetic core is obtained. Then the core 11 is held between both members 12 for reinforcement. A main magnetic pole part 10 contains a main magnetic pole thin film 2 set right above the core 11 and substrates 3 holding the film 2 at both sides. A thin piece other than the amorphous metallic piece is also available at the part of the core 11 as long as it has high permeability. In such a case, the thickness of the thin piece is set effectively at <=100mum in consideration of the high frequency characteristics. Thus it is possible to improve the recording/reproducing efficiency and to reduce the inductance with a magnetic head.
