Title: Optical transmission equipment
Inventor: SAKAUCHI MASAHIRO
IPC: H04B10/80
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To provide optical transmission equipment for correcting the degradation of quenching ratio characteristics. SOLUTION: For continuous-wave beams(CW beams) 47 from a laser diode(LD) 40 for which the output is stabilized by an automatic power control(APC) circuit 41 and an automatic temperature control(ATC) circuit 42, a data signal 51 is amplified to the voltage amplitude required for driving an electro- absorption(EA) modulator 48, and afterwards, the strength is modulated at the EA modulator 48 by a modulator drive signal 53 to which a DC bias is applied by a bias tee 52. Modulated signal monitor light 59 which is split by a beam splitter 56 is optically/electrically converted opto-electrically, while detecting the optical power level through a second photodetector 59.  Meanwhile, with the optical power level detected by a first photodetector 44 as a reference, the bias level of the EA modulator 48 is controlled, so that the optical power levels detected by the first and second photodetectors 44 and 59 can be made into a predetermined ratio.

Title: Refrigerating circuit for automotive air conditioning
Inventor: TERAUCHI KIYOSHI
IPC: F25B1/00
Filed: 1984-10-01
Abstract: PURPOSE:To prevent an extraordinary rise of temperature of the discharging gaseous refrigerant in a refrigerating circuit for automotive air conditioning, by forming a system arranging a choking element parallel to an evaporator. CONSTITUTION:An orifice 5 which has no heat exchange function is furnished parallel to an evaporator 4. As a result, a bypass flow Q' to the orifice 5 decreases or increases depending on the pressure loss DELTAP within the evaporator 4, and the flow Q' is proportional to the flow Q through the main circuit. Since this liquid refrigerant flows into the inlet of the compressor 1 without heat exchange, it can reduce the overheat DELTAT of the gaseous refrigerant sucked in from the compressor 1. Thus, even when the refrigerant flow Q through a high engine speed area is in a large flow area, an extraordinarily high temper ature of the discharging gaseous refrigerant is prevented.

Title: Teaching method for automatic machine tool
Inventor: FUJINAGA SHIGEKI
IPC: G05B19/42
Filed: 1987-08-18
Abstract: PURPOSE:To enable an operator to easily and accurately teach his/her desired points while maintaining the fast operability and the simplicity of an automatic teaching system, by securing such a constitution where the teaching actions are automatically carried out by a machine tool as long as the teaching points are shown within the screen of a picture sensor without drawing the detailed ruled lines on a work. CONSTITUTION:An operator moves manually an end effector T of a machine tool up to a positions near the teaching points TPi after marking manually only these points TPi without drawing the working lines like the ruled lines, etc., on a work W. Then the teaching point is caught by a picture sensor head SH provided near the effector T. Then the state value of each freedom degree is calculated to position the effector T at the point TPi based on the planar coordinates of the TPi within a screen and the state value of each freedom degree of the machine tool. These obtained state values are stored in a memory. This operation is repeated so that the teaching actions are successively carried out. As a result, even a beginning operator can teach accurately his/her desired points while maintaining the fast operability and the simplicity of an automatic teaching system without the need of skill.

Title: Information setting device
Inventor: EGUCHI MASAHARU
IPC: H03M11/04
Filed: 1987-08-17
Abstract: PURPOSE:To simplify a switch pattern by forming a contact range part for a common terminal of a conduction pattern with a pattern divided into plural areas and using plural brush groups arranged with displacements in the relative moving direction as those switches sharing a substrate and a pattern. CONSTITUTION:The conduction patterns are arranged with each displacement given by a single brush terminal on a pattern surface 1 in the direction vertical to the advance directions (a) and (b) of brush terminals a0-a2 and b0-b2. At the same time, these brush terminals are arranged alternately in both directions (a) and (b). Thus the terminals a0-b2 are set laterally on the vertical lines AA' and BB' vertical to the directions (a) and (b) on the surface 1 and have contact with this surface 1. The terminals a0 and b0 pass alternately over both patterns 2 and 3 as they advance and then pass over only one of both patterns since these patterns are set vertically to the directions (a) and (b) on the surface 1 with a positional shift secured between both patterns. In such a way, a switch pattern form is simplified.

IPC: G01C1/00
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a direction-of-sun detector which can detect the direction of the sun with high accuracy by catching the sun over a wide range. SOLUTION: When the direction angle of the sun is not large, the sunlight 5 is reflected by a mirror 16 set on the internal bottom face 14 of a sensor section after passing through a slit 3, reaches solar batteries arranged in parallel on the internal top face of the sensor section, and generates an electromotive force. This information is transmitted to a signal processing section 7 through an encoder 9 and the solar battery in which the electromotive force is generated is discriminated. Then the distance (d) between the arriving point of the sunshine 5 and the slit 3 is found and the angle between the direction perpendicular to the internal bottom face 14 of the sensor section and the direction of the sun is calculated by using the distance (d) and the distance between the internal top face 15 of the sensor section and the mirror 16.

Then, data receiving state is discriminated, e.g. into four kinds of state on the basis of the obtained packet error rate, and display information corresponding to the discrimination results is generated and supplied to the circuit 8. Thus, the part 9 performs accurate display corresponding to the data receiving state.

Title: Breakage preventing device for cable with connector and preventing method therefor
Inventor: SHIOZAWA TAKESHI
IPC: H01R13/56
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent breakage caused in a border section between a cable and a connector in the cable having a connector. SOLUTION: This device is composed of an attaching part 2 for fixing to a connector bush 4 of a cable 3 with a connector or to a connector main body 5, and a support 1 for placing the cable. Bending is not caused in a border defined between the cable 3 and the connector bush 4, and the connector of the cable or its portion held in a slightly apart relationship is subjected to bending. Since the cable 3 is not fixed, along the portion of an end part of the support 1 the cable 3 bends in such a way such that it draws a gradual curve. Therefore, bend parts are not concentrated in a single place, and stress is dispersed so that breaking of the cable 3 is not generated.
