IPC: G11B20/04
Filed: 1993-04-30
Abstract: PURPOSE:To provide the magnetic recording and reproducing device capable of automating the regulation of a reproducing sensitivity including the adjustment of variations of a level amplifier. CONSTITUTION:A square wave signal generated from a square wave generating means 17 is outputted from a square wave generating means 17 and is integrated by an integrator 20 at the time of reproducing sensitivity adjustment.

Title: Sliding bearing
Inventor: KISO MATAICHIROU
IPC: F16N39/00
Filed: 1981-08-07
Abstract: PURPOSE:To prevent foreign materials mingled in lubricating oil from intruding onto a lubricating surface by installing a sieve, which divides the inside space of a bracket into an upper and lower portions, in the lubricating oil in a bracket, to which bearings metals are fixed, and in the vicinity of the bottom of the bracket. CONSTITUTION:A plate sieve 13 is installed at the bottom part of a lower bracket 2. Since passing holes 14 made in the plate sieve 13 are formed in  curved shapes expanding upward, foreign materials such as dusts and metal,  which have been mingled into the lubricating oil during a sliding bearing 101  assembling/ disassembling process or during the lubricating oil 8 replacing process, tend to be caught more easily at the bottom of the lower bracket 2 than  by the plate sieve 13. The foreign materials thus caught under the plate sieve  13 do not soar beyond the plate sieve 13 even if the rotation of a rotary shaft 7  rotates an oil ring 9 and stirs the lubricating oil 8. This prevents the foreign  materials from intruding into the gap between the rotary shaft 7 and an upper  metal 5 or a lower metal 6.

Title: Horizontal deflection circuit
Inventor: IIZUKA HIROSHI
IPC: H04N3/16
Filed: 1995-05-24
Abstract: PURPOSE: To minimize a loss of a horizontal output transistor(TR) even when an operating frequency of a CRT is fluctuated. CONSTITUTION: In a base circuit 20 receiving a secondary output of a drive transformer 6, a coil L2 is provided in series with a series resistor R and a FET switch Q1 is provided in parallel. TR Q1 is turned on only when a horizontal oscillating frequency is low. Since the TR Q1 is conductive when the horizontal oscillating frequency is low, a base current of a horizontal output TR Q of the next stage is increased. When the frequency is high, the base current is decreased together with the action of the coil L2. As a result, the loss in the horizontal output TR Q is reduced.
