Title: Automatic correction method for input position coordinates
Inventor: MUROFUSHI HIROSHI
IPC: G06F3/048
Filed: 1984-11-24
Abstract: PURPOSE:To attain the automatic correction of input position coordinates by providing switches to an input position detecting circuit to produce the coordinate signals equivalent to the inputs of original on a tablet surface and full-scale points. CONSTITUTION:A switch 5 for production of an original point position signal and a switch 6 for production of full-scale point position are turned on and off successively by control signals A and B after confirming that no input exists before a control system is set under a tablet application mode. Thus initial data 11 and 12 are fetched and the correction value is calculated from these data and stored through the control system. This corrected value is equal to a prescribed original point signal B and Xmax/Xmax. In such a way, the corrected value is stored for each of the XY orthogonal coordinates. The input position coordinate signal is actually used for processing of the picture display, etc. in the control system after the real input coordinate value is calculated from a correction formula X=(x-B).Xmax/Xmax.

IPC: G03F7/20
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To easily make a plate with a small printing plate gain in an image of fine dots and lines or white voids by using a means to decrease the intensity of a main exposure light source by half or more to expose. SOLUTION: A transparent substrate 2 is mounted on spacers 8, 9 arranged to determine the thickness of a photosensitive resin plate. Back exposure (masking exposure) is carried out by irradiation of active rays through the transparent substrate 2 to form the base of a relief part. Then relief exposure is carried out by irradiation of active rays through a negative film 3 and a transparent substrate 1 to form the relief part of the image 12. In the relief exposure process, an attenuator screen 12 which reduces the intensity of active rays by >=50% is disposed between the light source of relief exposure and the transparent substrate 1. Then the masking film 7 is removed, and back exposure is carried out through the transparent substrate 2 to fix the formed relief part and a base film 6.  The reduction rate of the light source for relief exposure is usually controlled to 50 to 80%, preferably 55 to 70%.

Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To make temperature of each secondary battery uniform by arranging a plurality of secondary batteries so that parts electrically insulated from a pair of positive and negative current taking out terminals are brought into contact with each other. SOLUTION: Each secondary battery 2 has a metal battery can 21 electrically insulated from a current taking out terminal. Since battery cans 21 of a plurality of secondary batteries 2 directly come in contact with each other, temperature of the inside battery and that of the outside battery are made uniform. In order to efficiently make temperature uniform, the outer circumferential surface of each battery can 21 is ground to form a flat contact surface 22. For example, in the battery can 21 having an outer diameter of 60 mm, by grinding the surface to a depth of 0.75 mm, the contact surface 22 having a width B of about 13 mm is formed. By direct contact of contact surfaces 22 of the battery cans 21, wide thermal conductive area is formed between the secondary batteries, and temperature of each secondary battery 2 is made uniform.

Title: Observation apparatus of air flow in wind-tunnel
Inventor: NAKANO SUSUMU
IPC: G01M9/06
Filed: 1990-09-19
Abstract: PURPOSE:To visualize the outline of air flow to catch it by making a mixed gas containing a diacetyl molecule and a gas containing no oxygen flow along the wall of a wind-tunnel nozzle and exciting the part by laser. CONSTITUTION:Without hardly mixing up with air, which is a working fluid in a wind-tunnel, flowing in a nozzle, a mixed gas containing nitrogen and diacetyl vapor 8 supplied to the nozzle flows along the wall of the nozzle and jets to the space in a measuring part of the wind-tunnel. At that time, the diacetyl molecule is excited by laser light from a laser oscillator 9. Since the collisions of oxygen and diacetyl molecule against each other are few in this region, the excited diacetyl molecule emits fluorescent light of about 520nm wavelength. Consequently, the flowing condition alteration of the gas flow in the wind-tunnel can be easily caught using the model sample inserted into the measuring part 11.

Title: Air conditioner
Inventor: TANIGUCHI EIJI
IPC: F24F11/02
Filed: 1990-09-17
Abstract: PURPOSE:To prevent an operation of a compressor from being frequently stopped by a method wherein a second pressure switch detects a variation in a discharging pressure, an electrical energization for an auxiliary heater is stopped, and an increasing of the discharging pressure is restricted. CONSTITUTION:An outdoor blower control device 12 normally sets an outdoor blower 11 to have a maximum amount of air when a heating operation is carried out. Hot air is supplied by an auxiliary heater 8 to an indoor heat exchanger 3 and then a condensing temperature of refrigerant is increased. The condensing temperature and a discharging pressure of a compressor 1 are rapidly increased when the indoor and outdoor temperatures are high. At this time, a second pressure switch 7 reaches the second predetermined value and then the control device 12 sets an amount of air of the blower 11 low or stops the operation of the blower 11. Evaporating capability of an outdoor heat exchanger 5 is reduced and the discharging pressure is decreased. A heater control device 10 stops an electrical energization for the auxiliary heater 8 and decreases the discharging pressure. As the discharging pressure is decreased to the third predetermined value, a time counting of a timer 9 is started and the control device 10 returns the setting of the air volume of the blower 11 to its maximum value. The heater control device 10 stops an electrical energization for the auxiliary heater 8 until the time counting of the timer 9 is completed.

Filed: 1983-12-29
Abstract: PURPOSE:To stabilize transfer performance and conveyance performance by shifting the position of a guide member which guides a transfer material according to variation in the thickness of paper, and making the passing path of the transfer material to an image carrier constant. CONSTITUTION:A detecting means which detects the thickness of the transfer material is provided on the path of the transfer material 3. This detecting means operates as a conveyor roller, and when the transfer material 3 conveyed by rollers 9 and 10 varies in thickness (t), the driven roller 10 driven in press contact by the force P of the driving roller 9 generates force P' as shown by an arrow. The difference between the constant force P and varying force P' is detected by a pressure sensor 11 such as a strain gauge to obtain the displacement extent of the driven roller 10. This displacement extent corresponds to the thickness (t) of the transfer material 3. Then, an arithmetic controller 12 is provided to calculates the relation between the displacement extent and positions of preset transfer guides 5 and 6 and move the transfer guides 5 and 6 to proper positions. This arithmetic controller regards the distance (a) between a tangent to the image carrier and the tip of the guide 5 as a controlled variable during guide position movement.

Title: Production of magnetic recording medium

IPC: G11B5/84
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To improve the smoothness of a coating film after a calender treatment and to stabilize the output value of output waveforms after magnetic recording by executing the calender treatment while applying the collision energy of a pair of rolls by movable spherical bodies to these rolls. SOLUTION: A metallic body 5c is internally provided with a cavity part 6 and the spherical bodies 7 are inserted into the cavity part 6. Metallic balls of, for example, 2 cm in diameter are used as the spherical bodies. A substrate (PET of 50 cm in width) having a magnetic layer is subjected to the calender treatment by using such rolls 1c. The calender treatment is executed while the collision energy to the rolls by the movable spherical bodies is applied to the rolls, by which the variation in the pressure in the transverse direction of the rolls is suppressed and since the pressure fluctuation is suppressed in terms of time as well, ruggedness may be smoothed. Consequently, the output value of the output wavelengths when high-frequency signals are written to the medium after magnetic recording by a timing head and are read is stabilized.
