Title: Optical isolator
Inventor: MIYANO YOSHITO
IPC: G02B27/28
Filed: 1989-11-20
Abstract: PURPOSE:To allow the easy constitution of an optical integrated circuit by alternately depositing thin films of metals and dielectrics on a slope to form an analyzer, enveloping a clad layer, Faraday rotating part, etc., with a clad layer and disposing a magnet on one of semiconductor substrates. CONSTITUTION:The clad layer 7 is coated with the core layer 3 and the Faraday rotating part 4 and is formed on the clad layer 2. The length of the Faraday rotating part 4 and the intensity of the magnetic field by the magnet 8 are so adjusted that the direction of polarization is rotated 45 deg. by a Faraday effect. Only the polarization mode (TE mode) parallel with the metallic film on the surface of a polarizer 5 is selected as the light of the single mode sent from a light source through the core layer 3 and the polarization direction is rotated 45 deg. from the TE mode during the passage through the Faraday rotating part 4 so as to pass the analyzer 6. Since a single crystal material is not used, the optical isolator is freely formed on the optical integrated circuit by using sputtering and vapor deposition. The formation of the integrated circuit as one chip is possible and the cost thereof is reduced.

Title: Humidity control method for small volume space
Inventor: MIYASAKA CHIAKI
IPC: G05D27/00
Filed: 1990-11-07
Abstract: PURPOSE:To make it possible to easily maintain the temperature and humidity of a small volume space at predetermined values by controlling saturated air whose relative humidity is nearly 100% at the second temperature outside the small volume space, by heating the saturated air to the first temperature, and by supplying the heated saturated air to the small volume space. CONSTITUTION:In order to maintain a small volume space 2 at an internal temperature and humidity at 40 deg.C and 60%, respectively, a damped air i-x chart is used to obtain a steam volume of 0.0285kg for 1kg of atmosphere necessary to maintain the small volume space at a temperature of 40 deg.C and relative humidity of 60%. Next, in this case, a temperature that maintains 1kg of atmosphere at a relative humidity of 100% is 30 deg.C. Next, saturated air at 30 deg.C is generated in the upper space 5a of the second chamber 5. Saturated air at 30 deg.C that fills the prepared upper space 5a is fed to a heat exchange 3 via pipe 4, and heated at 40 deg.C in the heat exchange 3. On the other hand, since an amount of saturated steam for 1kg air at 40 deg.C is 0.0475kg, the relative humidity of air discharged from the heat exchange 3 becomes 0.0285/0.0475X100=60%. When this air is fed to the inside of space 2, the inside of space 2 is maintained at 40 deg.C and 60% as desired.

Title: Toaster
Inventor: AOYAMA MICHINARI
IPC: A47J43/046
Filed: 1987-11-27
Abstract: PURPOSE: To obtain bread baked without a recess at the central part of the upper face, by providing a baking instrument with a controller temporarily actuating a fan air-blowing to a container at the initial state in the baking process. CONSTITUTION: When air is blown toward a container 7 in an inner case 3 by actuating a fan 17 when the detected temperature of a thermistor 16 has rised to 70 deg.C in the initial state of the baking process, as the upper face of the bread raw material during the baking process is dried and hardened by the blowing air, any recess is not formed on the upper central part of the baked bread. Since the detected temperature of the thermistor 16 becomes constant at about 70 deg.C by driving the fan 17 in the initial state of the baking process, the temperature difference between the inside of the bread raw material in the container 7 and the surface thereof is not brought. And hence, evenly baked inside the bread can be obtained.

IPC: G06F9/44
Filed: 1990-11-05
Abstract: PURPOSE:To attain the efficient selection of a feature quantity and the determining of a membership function by executing the determining of a separating degree to represent the degree of the separation of a good product and a defective product of the feature quantity obtained from the picture information of an inspection object and using the separating degree. CONSTITUTION:The determining of a separating degree to represent the degree of the separation of a good product and a defective product of a feature quantity obtained from the picture information of an inspection object is executed and an examinated result is outputted by fuzzy inference with the feature quantities as input. Besides, when the feature quantity selected with using the separating degree is used for the fuzzy inference, a membership function is determined with using an average and standard deviation used for the determining of the separating degree. Thus, the efficient selection of the feature quantity and the determining of the membership function can be executed because of the fuzzy inference and not relying on the perception, the experience and the trial and error of human beings.

Title: Immersed nozzle for cast slab having homogeneous surface layer
Inventor: TAKAHASHI HIROMI
IPC: B22D11/10
Filed: 1993-11-08
Abstract: PURPOSE:To produce a cast slab having homogeneous surface layer by providing a tubular body to cover nozzle outer peripheral in order to control discharge flow. CONSTITUTION:A nozzle 1 can optionally select a shape of its discharge hole 3 but the discharge hole 3 is preferable not to be immersed for controlling flowing of molten metal. The outer periphery of nozzle 1 is coverd by a tubular body 2. The discharge flow of molten metal discharged from the nozzle 1 is controlled by the tubular body 2. This can reduce the phenomenon that by flowing of the molten metal discharged from immersed nozzle, the molten metal having high carbon concentration is discharged at the boundary between solidified shell and nozzle, negative segregation is generated so as to generate variance in formability. It is preferable to have an integrated structure so that the joint part between the nozzle and tubular body 2 is of screwed structure. By this method, when steel is used for wire rod for spring, the formability is improved.

Title: Drive controller for dc brushless motor
Inventor: KAWAMOTO RYUJI
IPC: H02P6/06
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent the driving efficiency of a motor from deteriorating while suppressing fluctuation of torque by comparing a specific input signal to each comparator amplified through an amplifier with other output signals thereby compensating for the delay of a conduction current. SOLUTION: An amplifier 20 for amplifying only one of two output signals H (HU, HV, HW) of respective phase being inputted to respective comparators 17 is inserted. A first comparator 17U compares a signal HU1 multiplied by an amplification factor with an output signal HV of phase V to produce a comparison signal HU2. Other comparison signals are also produced similarly. Consequently, the driving efficiency of a motor can be prevented from deteriorating while suppressing fluctuation of torque by correcting the commutation timing of current flowing through each armature coil 7 (7U, 7V, 7W) to a regular commutation timing thereby easily correcting the mechanical positional shift error between the armature coil and a rotor position detector 8 electrically.

The tube 22 has an elliptical section in its tube 26a insertion side. A heater 24 surrounds the tube 32. The tube has an insertion port with a wafer fitting groove. The groove is formed, so that the wafer 26a is tilted at an angle in its not falling range, e.g. at an angle of about 30-60 degrees for the horizontal-inserting type tube 22 and at an angle exceeding 0 degrees and not larger than 90 degrees for a vertical-insertion type tube 22, and then loaded into the insertion port. Thereby the thickness and uniformity of a film formed on the wafer 26a can be improved.  When arbitrary impurity is made to diffuse into the wafer 26a, an impurity diffusion profile can be made uniform and a semiconductor element can be improved in reliability.

Abstract: PURPOSE:To reduce a shock by communicating a secondary pressure chamber with the first adjustment chamber through two oil passages, and closing one of the oil passages with the movement in such an direction as enlarging the volume of the first adjustment chamber of a free piston. CONSTITUTION:The first adjustment chamber 39 is demarcated from the second adjustment chamber 40 by slidably engaging a free piston 38 between a casing C and the outer periphery of a relief housing 30.
