Title: Magnetic disk substrate and its production
Inventor: GOTO FUMIO
IPC: G11B5/84
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To improve durability of a head in a CSS zone by forming a thin solgel film on a glass substrate and irradiating the film with laser light under selected conditions to form minute projections. SOLUTION: A glass substrate 11 is used for a magnetic disk substrate 10 and a thin solgel film 12 is formed thereon. For example, after a sol soln. of Si-alkolate is applied on the glass substrate 11, the film is baked at specified temp. and irradiated with laser light to form minute projections 12a. Further, the film is subjected to secondary baking to form a dense amorphous oxide film. By irradiating the solgel film with laser light, the irradiated area is locally heated and the reaction proceeds to form projections. Since a solgel film to certain film thickness can be made as a dense film with good adhesion property and has a levelling effect for the base surface. Thus, the surface property of the data zone 12D except for the CSS zone 12A can be maintained or improved.

Filed: 1985-12-25
Abstract: PURPOSE:To eliminate an unstable state right after a power source it turned on and to form a reference voltage generator circuit where its output quickly rises by adding two fixed current circuits to the emitters of two bipolar transistors. CONSTITUTION:In terms of a closed loop circuit, the fixed current circuits I1 and I2 are connected to the emitter 5 of the transistor Q1 and the emitter 4 of the transistor Q2, respectively. The titled circuit is constituted so that when the same current is flowed in two bipolar transistors, a voltage across the base and the emitter of one transistor can be different from a voltage across the base and the emitter of the other transistor. In order to set the voltage VBE1 across the base and emitter of the transistor Q1 larger than the voltage VBE2 across the base and emitter of the transistor Q1, the emitter size of the Q2 is larger n-times (n>1) that of the Q1. At the time of turning on the power source, instantaneously the fixed current circuits I1 and I2 operate, and therefore a potential difference between the emitters 4 and 5 of the transistors Q1 and Q2 is caused, and a such a voltage drop arises that feedback is applied to balance the positive phase input 6 of an operational amplifier and its reverse phase input 5 by a resistance 2.

Title: Resonance frequency stabilizing method and resonance type optical deflector
Inventor: INOUE YOSHIAKI
IPC: H04N1/12
Filed: 1989-11-13
Abstract: PURPOSE:To make a temperature fluctuation small at the time of scan and at the time of non-scan, and to reduce the fluctuation of a resonance frequency caused by the temperature variation by applying a heating value to a resonance driving system of a deflector at the time of non-scan. CONSTITUTION:A rotor 18 fixing a light beam reflecting mirror 16 is supported by leaf springs 20, 22, 24 and 26, and a magnet 32 on the right side of the rotor is inserted into a coil part 34. When the current of a resonance frequency is allowed to flow to a driving coil from a control circuit 40, the reflecting mirror 16 is oscillated by the resonance frequency. Subsequently, at the time of non-scan, it is switched to an external signal whose frequency is different from the resonance frequency of an external signal generating device 42 by a signal switching device 44. At this time, since the current of the same power as the time of scan is applied, the heating value of the drive coil and a temperature distribution become almost the same, the fluctuation of the resonance frequency caused by the temperature fluctuation is suppressed and an image having a high-definition is obtained.

IPC: A47J37/00
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive bread maker that can make genuine preserve-style jam in a short period. SOLUTION: This bread maker, which is inexpensive to manufacture owing to freedom from transmission and fan motors, employs a single kneading blade 9 to not only knead dough, but also make genuine preserve-style jam in a short period while preventing jam materials from splashing, being mashed, scorching, and boiling over and avoiding burns and scalds as follows. First, with the kneading blade 9 stopped, a heater 7 heats jam materials at a current carrying rate of 90% or more up to a preset temperature between 110 and 130 deg.C. When the preset temperature is exceeded, the heater 7 is shut down and the kneading blade 9 is rotated for agitation intermittently, wherein the rotation time is 0.2 seconds or less and the stop time is at least ten times as long as the rotation time, until a temperature drop below the preset level when the kneading blade 9 is stopped and the heat 7 is activated again at a current carrying rate of 80% or more. Finally, the jam made through the intermittent rotation of the kneading blade 9 is brought to a cooling step where it is agitated for natural cooling with the heater 7 stopped.
