Title: Production of microlens array
Inventor: ASAHARA YOSHIYUKI
IPC: C03C15/00
Filed: 1985-10-04
Abstract: PURPOSE:To easily produce the titled plate microlens array wherein lenses having large numerical aperture and diameter are arranged by forming a columnar protrusion on the surface of photosensitive glass by etching, welding low m.p. glass thereon and softening the glass. CONSTITUTION:A photomask 1 wherein many circular shielding parts 2 are arranged on the surface of the photosensitive glass and UV rays are irradiated. Then the photomask 1 is removed, only the irradiated part is crystallized by heat treatment, the material is dipped in a weakly acidic soln. to etch only the crystallized part 5 and the unexposed part is formed as a columnar protrusion on the glass sheet. Then the powder of low m.p. glass 6 having a lower softening point than the photosensitive glass 3 is coated and heated to soften the low m.p. glass. The glass on the columnar protrusion is deformed into a spherical shape by surface tension and the shape of a convex lens is formed. Consequently, the microlens array wherein lenses with reduced aberration and having large numerical aperture and diameter are arranged is easily formed.

Title: Radio monitoring system
Inventor: KOGA YASUO
IPC: G08B25/04
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To perform the proper monitoring in response to the moving state of a slave unit by allowing a master unit to change a detection cycle according to the field intensity of the answer signal received from the slave unit or the changed variable of field intensity of the signal that is transmitted from the master unit and then received by the slave unit. SOLUTION: The count number N of a counter 14 is reset and a 1st timer 8 is started. A master unit 1 transmits and receives signals to and from a slave unit 2 when a 1st set time, i.e., a time cycle that is set by the timer 8 elapsed and detects the field intensity of the received signals to read the field intensity data D1. When the difference between the detected data D1 and the reference data exceeds the threshold S, the count number N of the counter 14 is increased up to 1. When the preceding field intensity data D2 are available, the data D2 are compared with the data D1. When the difference of both data exceeds the threshold S, the count value N of the counter 14 is increased up to 1. When the count number N does not exceed the set frequency C, a 2nd timer 9 is started. The set time of the timer 9 is shorter than the 1st set time.

IPC: B01J35/04
Filed: 1987-09-03
Abstract: PURPOSE:To prevent occurrence of breakdown or deformation at high temp. by providing diametrally penetrating holes from the external surface of the external cylinder contg. a honeycomb body inserted thereinto through the center of the cylinder, inserting a supporting member into each penetrating hole, and welding terminals of the supporting members to the external cylinder. CONSTITUTION:A honeycomb body 3 formed to a roll by piling thin steel plates 1 and corrugated plates 2 alternately and winding them is inserted into a cylindrical external cylinder 4. Then, diametral penetrating holes 11 penetrating through the external cylinder 4 and the center of the honeycomb body 3 are formed at two locations by electric discharge machining, for example, each to a rectangular shape to cross each other. Plate-shaped supporting members 5 having the same shape as the penetrating holes 11 are inserted into the holes, and both terminals of each member are fixed by welding 6 to the external cylinder 4. Since no brazing material is used in a metallic carrier 10 obtd. by this method, the upper limit of the working temp. is not restricted by the melting of brazing material. Therefore, the heat resistance and the mechanical stability are improved.

The modulators UM1, UM2 are driven through switches SW2, SW2 by the output of an oscillator SG2, modulated by different frequency to be incident to an absorption cell CL1. The transmitted light of the cell CL is synchronously rectified by a lock-in amplifiers LA1, LA2, and the oscillation frequencies of the lasers 1, 2 are controlled by current controllers CT1, CT2. Accordingly, the output of a plurality of wavelengths can be obtained in a high stability.

Title: Controlling of crystal growth direction
Inventor: IMAI YOJI
IPC: C30B25/02
Filed: 1989-08-29
Abstract: PURPOSE:To readily control crystal growth direction by decomposing gas of an oxygen-containing metallic compound with light irradiation, forming a thin film-like crystal of metal oxide on a base plate and growing the crystal to direction of light irradiation. CONSTITUTION:A base plate 2 is installed in a chamber 1 and gas of an oxygen- containing metallic compound (e.g. tantalum pentamethoxide gas) is introduced into the chamber 1 together with carrier gas 7. Simultaneously, light 4 from light source 11 is irradiated to the base plate 2 and the gas of oxygen-containing metallic compound is decomposed, then thin film-like crystal of metal oxide (e.g. tantalum pentoxide) is formed on the base plate, thus said crystal is grown to the irradiated direction of the light 4. By said method, the crystal growth direction is able to be controlled to a desired direction by controlling angle of the base plate 2 to the light 4, then various chemical and physical properties of the thin film are able to be controlled.

Title: Wheel for crane
Inventor: SUNAHARA SATOSHI
IPC: B60B5/00
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To travel a crane while safety is secured by forming a large number of slit grooves extending in the direction crossing the rolling direction of a wheel in the outer peripheral surface of an outer wheel. SOLUTION: This running wheel 1 is formed by mounting an outer wheel 3 made of synthetic resin on a metallic inner wheel, and a gear 1 for receiving driving force from a traveling motor inside in which a crane girder constructed in a saddle is extended is integrally formed with the inner wheel 4. Slits 8 extending in the direction orthogonal to the rolling direction of the traveling wheel 1 are cut at equal spaces in the outer wheel 3 made of urethane rubber. Thus, the frictional force of the wheel to a runway girder is increased and influence of an oil film deposited on the runway girder can be restrained to reduce the slipping risk of the traveling wheel. Thus, safe running of the crane can be performed.
