Title: Sample and hold circuit
Inventor: NARITA ATSUO
IPC: G06F3/05
Filed: 1989-05-22
Abstract: PURPOSE:To set a sample period and a hold period optionally by supplying sample hold signals whose phase is inverted to each other to 1st and 2nd primary windings provided on a pulse transformer in windings reverse to each other respectively. CONSTITUTION:First and second primary windings 8a1, 8a2 wound reversely to each other and sample and hold signals whose phase is inverted to each other are fed respectively to the 1st and 2nd primary windings 8a1, 8a2. Thus, the magnetic flux generated in the pulse transformer from the 1st and 2nd primary windings 8a1, 8a2 is generated reversely to each other to prevent magnetic saturation and electromotive forces generated in the 2nd winding 8b are of in-phase thereby improving the drive capability to a load. Thus, the magnetic saturation is prevented and the sample period and the hold period of a sample- and-hold signal are decided optionally.

Abstract: PURPOSE:To obtain developability, excellent image density and stability by adding low-melting glass powder to sintered powder obtd. by granulating and sintering ferrite powder exhibiting soft magnetism, subjecting the powder to a heat treatment to form a carrier consisting of irregular-shaped particles aggregated with plural pieces of spherical particles and using such carrier. CONSTITUTION:The low-metling glass is added to the sintered powder consisting of the partivles obtd. by granulating and sintering the ferrite powder exhibiting soft magnetism and the powder is subjected to the heat treatment to obtain the irregular-shaped particles aggregated with plural pieces of the spherical particles. Such particles are used. The linearity of a magnetic brush is weakened and the mixing power of the developer is increased if the irregular-shaped particles obtd. in such a manner are used as the irregular-shaped particles obtd. in such a manner are used as the carrier. In addition, the developing electrode effect in the peak part of the magnetic brush is increased and the developability is improved, by which the high image density is obtd. The sticking of the spherical particles forming the irregular-shaped particles is strong and the particles are hardly separable in the stage of mixing the carrier and toner. The image having a high grade is thus obtd. and the life of the carrier is extended.

Abstract: PURPOSE:To improve the voltage resistant quality of a color Braun tube by subjecting the tube  to high voltage treatment, and then vapordepositioning a conductive film on the inner wall of  the neck of the tube by subjecting a shielding electrode to dielectric heating. CONSTITUTION:During the process of voltage-proof treatment, the electric potential distribution  of the inner wall of a neck 16 is represented by both a curve (a) which indicates the electric potentials of an inner conductive film 15, and a curve (b) which has an ideal slant and indicates the electric potentials of a part of the inner wall of the neck 16, which is uncoated with  the film 15 and extends up to a stem part. Therefore, the high-voltage treatments of the fifth  to the first grids 10, 9, 8, 7 and 6 and a cathode 5, which are medium to low voltage electrodes, also are completely carried out. After such high voltage treatments are performed, a shielding electrode 9a is subjected to dielectric heating so as to make a conductive film 9b to  be vapordeposited on the inner wall of the neck 16 so that the film 9b corresponds to the electrode 9a. As a result, the electric potential distribution of the inner wall of the neck 16 comes  to be represented by a curve (a1) which indicates the electric potentials of the inner conductive  film 15, and a curve (b1) which indicates the slant of the electric potentials of a part of the  inner wall of the neck 16, which extends from the end of the film 15 through the conductive  film 9b toward the stem part. Consequently, the voltage resistant characteristic of the color picture tube is improved.

Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a luer capable of repeatedly detachably attaching a soft bait to a hook, prolonging the life in use of the soft bait and readily hooking up. SOLUTION: A lock pin 8 is attached to a head 4 and the tip side of the lock pin 8 is pierced into a soft bait 1 pierced into a hook 2. Since it is not required to provide a bait-holding part in the head 4 or the hook 2 like conventional method, the soft bait 1 is not damaged with a bait holding part. Consequently, the soft bait 1 can repeatedly be detachable to the hook 2 and is hardly damaged when a fish is hooked. As a result, the life spun of the soft bait 1 is prolonged. When a fish bites the soft bait 1, the position of the soft bait 1 to the hook 2 is shifted and the soft bait 1 covers the needle point of the hook 2 to facilitate hooking up.
