Abstract: PURPOSE:To prevent the black material paint film of a panel skirt section from being peeled off during development by wetting the black material paint film on the panel skirt section with a water spray during immersion of a release agent. CONSTITUTION:A resist layer 4 with a predetermined pattern is formed on the inside of a panel 1, and in reverse development of the black material paint film 6 after a black material paint film 6 is formed on the whole face including this resist layer 4, the black material paint film 6 on the panel skirt section 1a is wetted by a water spray during immersion of a release agent 9. Next, it is developed by this water spray to form a black material layer 7 with a predetermined pattern. That is, a release agent 9 is injected into the panel 1, and the black material layer 6 of the panel skirt section 1a is wetted by the water spray (i.e., sprayed water 12) during immersion of the release agent 9, thereby the panel skirt section is prevented from being dried. Accordingly, the granular peeling off of the black material paint film 6 on the skirt section 1a is prevented during development by this water spray, and the black material layer 7 with a desired good pattern can be formed.

IPC: G02B23/16
Filed: 1984-10-11
Abstract: PURPOSE:To attain an easy-to-see display, to eliminate variation in right ascension accompanying diurnal motion, and to reduce a device in weight and size by storing a right ascension value which is increased to the east corresponding to a unit time, calculating the right ascension value, celestial declination value, and said displacement value by a microcomputer, and displaying them digitally. CONSTITUTION:The right ascension and celestial declination values of an optional star put in the visual field of a telescope are inputted to a digital setter 5 and a right ascension axis is rotated to the west according to the diurnal motion of the star, so that a right ascension axis rotary encoder 1 outputs two pulse train signals CW and CCW. The microcomputer 13 converts the number of pulses into the quantity of deviation in right ascension value and subtracts this from a right ascension value stored in a RAM10 previously, so that the right ascension value on a digital display device 6 is constant even when the right ascension axis is rotated according to the diurnal motion. Then, the right ascension and declination axes are rotated to catch a desired star. Therefore, the display of the right ascension value is constant regardless of diurnal motion to facilitate astronomic observation, the right ascension and celestial declination are made easy to see and have high precision; and the device is reduced in weight and size.

IPC: H01J63/08
Filed: 1987-08-26
Abstract: PURPOSE:To lower light starting voltage and enable many electrons to be discharged at low voltage by arranging an auxiliary electrode for feeble discharge near a cathode. CONSTITUTION:The power source 10 is a power source of several 100volts and connected to an auxiliary electrode 4 through a resistance 11 of several 100KOMEGA to several MOMEGA. First, feeble discharge is generated between a cathode 2 and the auxiliary electrode 4 by the power source 10 of several 100volts. This feeble discharge is an order of several 100muA since the resistant value of the resistance 11 is large and the power consumed in this line is small at 0.1watt or less. However, sufficient amount of positive ions exist near the cathode 2 by this feeble discharge and negative space charge doesn't exist, thus sufficient numbers of electrons can be drawn from the cathode 2 with a low voltage power source 9 of 10 and several volts.

Title: Air mat
Inventor: MORIMOTO MIKIHIKO
IPC: A47C27/08
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To effect air-feeding action in a slow cycle. SOLUTION: A switching transistor 54 is controlled by first and second switches S1, S2 which operate according to the expansion and contraction of an air pressure regulating bag having an internal pressure which corresponds to the internal pressure of an air cell. The first contact 49 of the first switch applies a switch driving voltage to the transistor via a time constant circuit 51, and the second contact 55 of the first switch quickly discharges the charging voltage of the capacitor 52 of the time constant circuit. Thereafter, the feed of air to the air cell is continued for a certain period of time determined by a time constant, even after the internal pressure of the air cell has built up beyond the lower limit value of a high pressure area and the first switch turned off, with the result that the driving time of an air pump 7 is prolonged and its cycle becomes slower.  If external pressure is applied to the air cell during the feed of air to the air cell and its internal pressure builds up abruptly, the first switch is turned off and the second switch is turned on to quickly discharge the charging voltage of the capacitor of the time constant circuit to stop the air pump.
