Title: Single magnetic pole type composite magnetic head for vertical record
Inventor: HAYAKAWA ATSUNORI
IPC: G11B5/127
Filed: 1983-03-22
Abstract: PURPOSE:To obtain accurate data in a reproduction mode regardless of an attachment shift or a track shift by unifying a record/reproduction main magnetic pole and an erasion magnetic pole on the surface opposite to a magnetic recording medium via a nonmagnetic guard member. CONSTITUTION:A record/reproduction main magnetic pole 10 set opposite to a magnetic recording medium 11 is held between a magnetic core 13a and nonmagnetic core 13b and joined to nonmagnetic guard members 12a and 12b. Then erasion main magnetic poles 18a and 18b are provided at the downstream side of the pole 10 with a space smaller than the width of the pole 10. When the information is recorded in the medium 11, the record signal is supplied to the pole 10 to perform the vertical magnetic record. At the same time, an erasion current is supplied to the erasion main magnetic pole 18 to erase both sides of a recording track. Therefore no unerased previous data remains in a rewriting mode although some shift is caused with attachment of the medium 11 or a track shift due to a temperature change. Thus it is possible to obtain the accurate data in a reproduction mode.

Abstract: PURPOSE:To enable matching of the reference levels of the output wave-forms of a sine wave and a triangular wave easily by connecting two power supplies to a triangular wave generating circuit, using the neutral point as the reference level and passing the output of a sine wave generating circuit through a capacitor. CONSTITUTION:A variable power supply 5 controlled by the signals of a temperature, etc. is connected to the positive side and negative side of the sine wave generating circuit 1, and the output of the sine wave is supplied to a modulation circuit 3 through the capacitor 6. On the other hand, two power supplies 7, 8 are connected in series at the positive side and negative side of the triangular wave generating circuit 2, the neutral point is used as the reference level, and the output of the circuit 2 is fed to the modulation circuit 3. Accordingly, since the output wave-form of the sine wave is oscillated in the positive and negative directions by passing it through the capacitor 6, the output wave-form of the triangular wave is amplified between the positive side of the power supply 7 and the negative side of the power supply 8 and the optimum wave-form can be obtained as the input signals of the modulation circuit 3, signals for generating the three- phase AC output wave-form of an inverter can easily be acquired.

CONSTITUTION:A mixed gas of Ar with O2 and N2 from an air separation apparatus is  introduced from a pipe 1 into a buffer tank 2, pressurized in a compressor 3 and then  introduced through an inlet valve (4a) into the first adsorption cylinder (5a) of an adsorption apparatus 5 to adsorb the N in a nitrogen adsorbent (5a-MS) and O in an oxygen adsorbent (5a-CS) and recover the Ar gas, which is then fed through an outlet  valve (7a), pipe 8 and flow control valve 9 to a part to be fed. On the other hand, an  inlet valve (4b) and outlet valve (7b) of the second adsorption cylinder (5b) after completing the adsorption stage are closed to open a discharge valve 10 and a valve 11  and reduce the pressure to almost atmospheric pressure. The O and N gas in the second adsorption column (5b) are desorbed under reduced pressure and discharged to the outside. A purging valve (13b) is then opened to introduce part of the Ar through a pressure reducing valve 14 and a pipe 15 into the second adsorption cylinder (5b) to  wash and regenerate both adsorbents. The Ar gas is then released to the outside.  When the Ar gas in the released gas is in a given amount, the gas is returned through  a return valve 16 and a pipe 17 to the tank 2.

Abstract: PURPOSE:To prevent the deterioration in luminous efficiency of phosphor particles and eliminate the deformation of the panel glass itself, by burying parts of phosphor particles on a low melting point glass furnished on a panel glass. CONSTITUTION:Phosphor particles 2 are in the condition that they are buried at the surface of a low melting point glass layer 3 furnished on a panel glass 1.

The mean particle diameter of the phosphor particles is several mum, and their lower parts are closely contacted to the glass layer 3 while their upper side surface is exposed in the vacuum. Therefore, even though a low speed electron beam with the incident depth of only about 10Angstrom  can make the phosphorus luminous at a high efficiency. Furthermore, the deformation of the panel glass itself is eliminated.

Title: Display device
Inventor: IWASAKI TAKAO
IPC: H04N5/64
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a display device where a blurred picture is hardly viewed because the depth of focus is deep and further secrecy in terms of a displayed picture is made high. SOLUTION: This device is provided with a white LED 12 being a point light source emitting white light, a condenser lens 14, a liquid crystal display 16 and an image-formation lens 18. The LED 12 has conjugate relation with the pupil on the front surface of an eyeball 22, and the display 16 has conjugate relation with the retina 24. Since light condensed by a condensing optical system is given to a spatial optical modulation means from the point light source, the emitting angle of light emitted from the spatial optical modulation means gets comparatively small. Therefore, a converging angle in the eyeball when the light is made incident on the eyeball is small and the depth of focus gets deep. Then, the picture is hardly blurred when a focus is deviated from the retina.
