Title: Shape measuring instrument
Inventor: ISHIDA FUMIHIKO
IPC: G01B7/00
Filed: 1990-01-17
Abstract: PURPOSE:To measure a three-dimensional shape with high accuracy without being affected by the hysteresis of a piezoelectric element by finding the three- dimensional shape from the displacement quantity of a displacement sensor which detects the up-down displacement of a sample table and the XY movement quantity of the table. CONSTITUTION:The displacement sensor 20 is provided above the table 4 where a sample 5 is mounted and detects the up-down displacement of the table 4 and the processing result of a sensor 21 is sent to a shape calculation device 22. When a displacement lever 7 is displaced corresponding to the inter-atomic force generated between the sample 5 and displacement lever 7, a tunneling current flows between the displacement lever 7 and a probe 8. An interval controller 10 controls the interval between the sample 5 and displacement lever 7 to a constant interval corresponding to the current and the current XY- directional control voltage is sent to the shape calculation device 22. The three- dimensional shape of the sample 5 can be measured with this signal and said up-down displacement voltage without being affected by the hysteresis of the piezoelectric element 3.

Title: Turboblower for laser
Inventor: KARUBE NORIO
IPC: H01S3/036
Filed: 1994-01-25
Abstract: PURPOSE:To accurately supply oil to the bearing of a turboblower for laser which forcibly circulates a laser gas into a gas laser device. CONSTITUTION:The oil in a shaft supporting section 20 is sucked up from an oil inlet 30 by utilizing a centrifugal force generated by the rotation of a shaft 2 and discharged from oil outlets after passing through an oil passage 13 in the shaft 2. Then the oil enters an oil reservoir 18 through a oil returning passage while the oil is cooled by cooling water in a cooling water passage and returns to the shaft supporting section 20 through an oil passage 180 and through port 201. Part of the oil in the section 2 is drawn up along the tapered part 170 of an oil sucking-up head 17 by a centrifugal force associated with the rotation of the head 17 and supplied to a rolling bearing 6 for lubrication. Since the sucking-up amount of the oil can be adjusted by adjusting the angle of the tapered part of the head 17, an adequate amount of oil can be supplied to the bearing 6.

Abstract: PURPOSE:To obtain information terminal equipment which is inexpensive and superior in safety by providing first terminal equipment, second terminal equipment to communicate with the first terminal equipment, a first information carrier to communicate with the first terminal equipment, and a second information carrier to communicated with the second terminal equipment. CONSTITUTION:When the first and the second information carriers 10, 40 verify mutual rightnesses, and the rightnesses of both the information carriers are confirmed, the exchange and the processing of information are executed among the first information carrier 10, the first terminal equipment 20, the second terminal equipment 30, and the second information carrier 40. At that time, since the first and the second terminal equipments 20, 30 are arranged as being separated and connected by a communication line 50, by installing the second terminal equipment 30 at a safe place, the danger of the wiretapping of the second information carrier 40 is reduced. Besides, even if the communication line 50 connecting between the first and the second terminal equipments 20, 30 is wiretapped, since the information flowing here is only the enciphered result of a random number and the random number, the safety is never impaired. Thus, plural terminal equipments can be installed in a store inexpensively and safely.

IPC: H01L21/208
Filed: 1985-01-17
Abstract: PURPOSE:To obtain an active layer in narrow striped width easily, and to improve yield by etching and molding multilayer crystal structure for operating a laser grown on a substrate in an epitaxial manner to a mesa form and melting back the structure by using an unsaturated solution. CONSTITUTION:A double hetero-junction type epitaxial grown layer for operating a laser is shaped onto the (100) face of an N-type InP substrate 9. A laser operation section having inverted mesa structure is formed onto the InP substrate 9 through mesa etching processing. An unsaturated InP melt is brought into contact, thus melting back the growth layer on the surface of the laser operation section. There is a difference between the rates of melt-back in InP and InGaAsP, the quantities of melt-back of an active layer 11 and a cap layer 13 are made larger than those of a buffer layer 10 and a clad layer 12, and the striped width of the active layer 11 is narrowed to approximately 2.0mum, and takes a value sufficient for controlling a transverse mode and reducing threshold currents. Since the side end of the active layer 11 is etched, a section being subject to a thermal effect is removed, thus maintaining the excellent active layer 11.
