Abstract: PURPOSE:To obtain a reflecting type wave plate which can be produced easily, by reflecting a part of an optical beam by means of the surface of a light separating film and the other part by means of a reflecting surface after passing through the light separating film. CONSTITUTION:A reflecting film 14 provided with a reflecting surface 13 is formed on the surface of a substrate 12 b y multi-coating and a space layer 16 made of SiO2, silicon nitride, etc., is put on the reflecting film 14. Moreover, a polarized beam splitting film 18 is formed on the surface of the space layer 16 by multi-coating. When an optical beam L which is linearly polarized light having a plane of vibration inclined against the plane of incidence is made incident on the film 18, an S wave 22 and P wave 24 are respectively reflected by means of the polarized beam splitting film 18 and reflecting plane 13 and, therefore, a difference in the geometrical length of the optical path occurs between the S wave 22 and P wave 24 and a phase lag is produced.

Filed: 1985-12-09
Abstract: PURPOSE:To simplify the structure of a reel by meshing one of planet gears at both ends of a shaft with an internal gear at the outside of a bearing bracket of an electric motor, and also by meshing the other of the planet gears with an internal gear of an intermediating member arranged by way of a coil lowering member at the end of the shaft. CONSTITUTION:A rotating shaft 4, a reel support shaft 6 and a guide pipe 7 are rotated as an integral unit with an electric motor 1 energized, and an installation base 19 of a flyer 20 is also rotated simultaneously. The rotation of the base 19 causes planet gears 22 and 22a installed on a shaft 21 to rotate as internal gears 5 and 5a are rotated while an intermediating member 17 underneath the base 19, a coil lowering member 15 and a reel 10 installed on a reel installation stand 9 are kept at standstill. Accordingly, a wire 8 which is pulled out of the flyer 20 while running through the guide pipe 7, is formed into a coil C by the swinging flyer 20. Subsequently, a cylinder 35 is energized for elevating the support shaft 6 via a rod 31 and an arm 33 so as to lower the coil C downward by the arm 13. This constitution can eliminate a need for a preventive measure against rocking of the reel 10 so as to simplify the structure.

Title: Thesaurus preparing device
Inventor: SAKAMOTO HITOSHI
IPC: G06F17/30
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To automatically prepare thesaurus by inputting materials. SOLUTION: A morpheme analysis part 2 reads a character string, analyzes the character string into a string of words, and prepares and outputs a list of parts of speech of the respective words to a coocurrence extraction part. The cooccurrence extraction part 3 analyzes the list and extracts and outputs cooccurrence data to a coocurrence storage part 4. The cooccurrence storage part 4 stores the coocurrence data and appearance frequencies by data kinds in a storage device. A semantic distance calculation part 6 calculates the semantic distances between the words by a quantifying means from the data stored in the cooccurrence storage part 4 and outputs the calculation results to a thesaurus preparation part 7.  The thesaurus preparation part 7 divides the words into groups on the basis of the semantic distances received from the semantic distance calculation part 6 and further divides the groups into groups. After operation is completed for all the words, the thesaurus preparation part 7 outputs the words which are hierarchically grouped as a thesaurus.

Title: Sequencer
Inventor: ANPO TERUHISA
IPC: G05B19/05
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To decrease the number of lock designation check items of a coil instruction by preparing the check/non-check instruction processing for a lock designation data memory and switching the instruction processing according to the presence or absence of the lock designation. SOLUTION: A lock designation data memory 8 designates to individually and compulsively lock the contact data stored in a data memory 2 in an ON or OFF state. When a ladder program is carried out, the ladder program is debugged based on the data of the memory 2. Then the processing where the memory 8 is checked and an instruction is carried out if the lock designation is confirmed is prepared together with the processing where the instruction is carried out without checking the memory 8 if no lock designation is confirmed. In addition, a lock flag is prepared to show whether the lock designation is given to the memory 2 in an on/off state. Thus two types of coil instruction processing are carried out with switching according to the on/off state of the lock flag when the coil instruction of the ladder program is carried out.
