Title: Disk-shaped recording medium
Inventor: NAGAI YASUO
IPC: G11B7/24073
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for recording angular information separately at the recording of data, and also to make it possible to integrate data divided to each track by depending on the address information in the reproduction, by recording common address information in the position for recording the data to be reproduced at the same time at different angular positions of plural respective spiral form tracks. SOLUTION: Recording or reproduction of data divided to spiral form tracks SP1-SP4 is carried out by four optical pickups arranged at a 90 deg. angular difference. A sector of C1 part of the track SP1 is designated as an address 2000, and the same address 2000 is affixed to a sector of C2 part of the track SP2 rotated by 90 deg. from the track SP1. Similarly, the same address 2000 is affixed to the sectors of C3 in SP3 and C4 in SP4. Thus, it is possible in the reproduction to integrate the data divided to SP1-SP4 and recorded thereon, without recording timing information and angular information on optical pickup arrangement.

Filed: 1992-01-28
Abstract: PURPOSE:To obtain an excellent crystal having a smaller dislocation density at a barrier layer region by disposing a monoatomic layer of indium inside a buffer layer by an atomic-plane doping method. CONSTITUTION:A high purity i-GaAs layer 12 is grown to a thickness of 5000 angstrom on a Si monocrystal substrate 11. A planar-doped layer of indium is grown over that layer by an atomic-plane doping method. The high purity i-GaAs layer 12 is again formed to a thickness of 3000 angstrom over that doped layer. An n-AlGaAs layer 14 to which 2.0X10<18>cm<-3> Si is added is then formed to a thickness of 500 angstrom on the i-GaAs layer. Further, an n<+>-GaAs layer 15 to which 2.0X10<18>cm<-3> Si is similarly added is formed to a thickness of 500 angstrom over the n-AlGaAs layer. Thereby, it is possible to obtain an excellent crystal having a smaller dislocation density at a barrier layer region, and hence it is possible to manufacture an inexpensive compound device.

Title: Rotary head assembly
Inventor: SAKAGUCHI TAKASHI
IPC: G11B15/61
Filed: 1989-01-19
Abstract: PURPOSE:To reduce the generation of damage caused by the contact between a magnetic tape and a fixed cylinder, and to stabilize the running of the magnetic tape by specifying the pitch and/or notch quantity of an uneven surface on the side surface of a fixed cylinder. CONSTITUTION:The pitch of the uneven surface on the side surface of a fixed cylinder 1 is successively altered so as to be rougher on a rotary cylinder 2 side and so as to be closer on a lead 5 side, and the notch quantity is successively altered so as to be larger on the rotary cylinder 2 side and so as to be smaller on the lead 5 side. Consequently the gap between the side surface of the rotary cylinder 2 of the fixed cylinder 1 and a running magnetic tape 4 is made broad, and a part of air flow incoming by the rotation of the rotary cylinder 2 flows in along an uneven groove on the side surface of the fixed cylinder 1. For this reason, the friction between the fixed cylinder 1 and the magnetic tape 4 is decreased, the running of the magnetic tape 4 is stabilized, and the damage of the magnetic tape 4 is reduced as well.

Title: Oven for drawing optical fiber
Inventor: MATSUI MASAHIKO
IPC: C03B37/029
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To efficiently prevent the deterioration in the strength of an optical fiber by disposing a SiO2 glass protection pipe in an oven core pipe and placing the upper end of the protection pipe at a place below the lower end of a heat generator. SOLUTION: A heat generator 8 heats an oven core pipe 3 to give a temperature distribution comprising the maximum temperature at the central portion, a low temperature at both the ends, and temperatures gradually lowered from the central portion to both the ends. A protection pipe 4 which is coaxial with the over core pipe 3 surrounding the optical fiber 2 is disposed in the lower portion of the oven core pipe 3 so that the upper end of the protection pipe 4 is placed below the lower end of the heat generator 8. When the upper end of the protection pipe 4 is placed below the lower end wall 7c of an oven 7, a local low temperature portion effected by cooling water circulated in the lower end wall 7c can be eliminated.  Since the protection pipe 4 is produced from SiO2 glass, it is preferable that the upper end of the protection pipe 4 is disposed at a <=1,000 deg.C position to prevent the progress of crystallization.

Abstract: PURPOSE:To generate a digital signal train with a small-scale circuit constitution by counting the signal outputted from an oscillator to output respective digits of the counted value in parallel and providing a decoder which generates the digital signal train in accordance with this counted value. CONSTITUTION:A counter 1 counts an input clock signal after being initialized to 0 by a reset signal and outputs the counted value to inputs I1, I2, I3, and I4 of a decoder 2. When the counted value of the decoer 2 is 4, outputs of AND gates 7 to 11 are '0' and the output of an AND gate 12 is '1' because of I1=0, I2=0, I3=1, and I4=0, and therefore, the digital signal train output is '1'. Hereafter, the digital signal train output is '1' when the counted value is 6, 9, 10, 11, or 14, but it is '0' otherwise.

Abstract: PURPOSE:To measure the coercive force of a steel plate in a noncontact state without cutting off one part of the steel plate as a specimen in order to measure its coercive force. CONSTITUTION:A steel-plate excitation device 1 in which excitation coils 3a, 3b and a detection coil 4 have been executed to a U-shaped core 2 is arranged on a steel plate G under test in such a way that a gap is kepy between tip faces of both leg parts of the U-shaped core 2 and the steel plate S under test. An AC excitation current is made to flow to the excitation coils 3a, 3b which have been connected in series; the steel plate S under test is magnetized. A point of time when an induced voltage generated at the detection coil 4 takes a peak value at each magnetization half cycle is detected. Then, the following are detected: an excitation current value at a point of time when the induced voltage generated at the detection coil 4 takes a peak value at a previous magnetization half cycle; and an excitation current value at a point of time when the induced voltage generated at the detection coil takes a peak value at a next magnetization half cycle. Then, the mean value of absolute values of the excitation current values is found. The coercive force of the steel plate S under test is found on the basis of the excitation current value corresponding to the coercive force of the steel plate S under test.

Title: Developing device with toner supply port opening and closing mechanism
Inventor: SUGIHARAI SHIGERU
IPC: G03G15/08
Filed: 1987-01-22
Abstract: PURPOSE:To prevent concentration from decreasing and to improve print quality by providing a control plate which is constituted integrally with a toner supply port lid and controls the opening and closing of the toner supply lid and a spring fitted between a support and the toner supply port lid. CONSTITUTION:When the amount of a developer in an agitation area 11 is large, the pressure in it increases to press up the control plate 12, and the toner supply port lid 13 united with the control plate 12 operates in such a direction that a toner supply port is closed. When the amount of the developer is small, on the other hand, the pressure in the agitation area 11 drops, the control plate 12 is lowered with the force of the spring 14, and the toner supply lid 13 operates in such a direction that the toner supply port is opened. Therefore, this series of operations decrease the supply amount of toner when the amount of the developer in the agitation area 11 is large or increase the toner supply amount when not. Consequently, a decrease in concentration due to a deficiency in the supply of toner and the condensation of the developer caused by oversupply are evaded to preclude an irregularity in concentration due to the condensate, thereby obtaining stable picture quality.
