Title: Photoelectromagnetic recording medium and its production
Inventor: NIIHARA TOSHIO
IPC: G11B11/10
Filed: 1984-12-24
Abstract: PURPOSE:To make a recording and reproducing device uncomplicated even when photoelectromagnetic records are formed on both surfaces of the device by making the direction of the initial magnetization of the photoelectromagnetic recording layers on both surfaces to the injecting direction of a laser beam not to differ from each other. CONSTITUTION:Amorphous thin films 12A and 12B of Tb28Fe74 and protective films 13A and 13B of SiO2 are formed on glass substrates 11A and 11B by sputtering, and a magnetic field Hex is impressed to establish the direction of initial magnetization (all '0') of two recording mediums 10A and 10B. Since the concn. of Tb is in excess of the compensating composition, the magnetization MRA and MRB coincides with the direction of the external magnetic field Hex. Accordingly, the magnetization MTA and MTB of Fe contributing to the direction of the Kerr's rotating angle is directed respectively toward the substrate side, The two recording mediums 10A and 10B are stuck to each other by using an adhesive 15 to prepare a recording medium 16.

Title: Laser driver circuit
Inventor: DOI AKIHIKO
IPC: G11B7/125
Filed: 1988-10-28
Abstract: PURPOSE:To avoid destruction of information by a method wherein a laser light source can be operated only when a supply source is normal. CONSTITUTION:If one or both of source voltages +V and -V is abnormal, an electric source level detector 23 outputs an L-level detection signal 23a or 23b even if an H-level light emission instruction signal 5a is outputted by a CPU 5. A switching signal generator 25, therefore, outputs an L-level light emission instruction signal 25a. In accordance with the instruction signal 25a, a switching circuit 3 prohibits an electric source supply to a semiconductor laser 7. If the source voltage is not normal, therefore, the operation of the semiconductor laser 7 can be discontinued securely. This constitution prevents the damage to a light emission source and the destruction of optical information.

Title: Impact buffer device
Inventor: TAKEZAWA SHINICHI
IPC: B25J17/02
Filed: 1990-10-08
Abstract: PURPOSE:To prevent the damage caused by collision of a tool and a robot by providing a pressurizing means for pressing the end face of a piston sliding part from the closed side of a cylinder to its open side, and control means for controlling the function of a pressure reducing means to reduce pressing pressure. CONSTITUTION:When a tool or the like collides against any obstacle during the operation of a robot to make resistance force caused by collision act onto a piston, the resistance force rises pressing pressure. A control means 15 detects the rising of the pressure through a pressure detecting means 11, and when the detected pressure is above preestablished pressure, a pressure reducing means 10 is actuated to reduce the pressing pressure acting onto the end face of a piston sliding part. The tool and the piston 4 which undergo the resistance force caused the collision can therefore move to the closing side of a cylinder 1, and are relieved from the resistance force. Thus the tool and the robot arm can be prevented from the damage caused by the collision.

Title: Parts feeder
Inventor: DOKE HIROSHI
IPC: H01L41/09
Filed: 1984-12-24
Abstract: PURPOSE:To enable a device to be miniaturized, noise to be suppressed and also enable vibration to be reduced in the device where a vibration plate is allowed to be excited by leaf springs as required as referred to the title by arranging a piezoelectric-crystal element of a bimorph cell on the leaf springs allowing the displacement within the piezoelectric-crystal element to cause excitation. CONSTITUTION:Electric voltage with the stated resonance frequency is applied to a piezoelectric-crystal element 20 by a high frequency electric power source 21. This allows a leaf spring 2 to vibrate right to left enabling a vibration plate 1 to produce both horizontal and vertical components of a force. This configuration enables the amplitude of vibration to be extremely small and noise produced by leaping of carried particles on the vibration plate 1 to be reduced. In addition, change in resonance frequency allows a conveying speed to be changed as required. Thus, only the stick of the piezoelectric-crystal element 20 makes the construction simple enabling the device to be miniaturized.
