Title: Lighting device for instrument
Inventor: AOYAMA TORU
IPC: G10H1/00
Filed: 1995-01-09
Abstract: PURPOSE: To automatically light an operation part with optimum brightness according to environmental brightness by detecting the brightness and outputting a control signal according to the detected result to a lighting means. CONSTITUTION: The environmental brightness is detected by a brightness/ darkness detection device. The detected result of the brightness/darkness detection device is sent to e.g. a CPU 10 forming a part of a control means. The CPU 10 forms the control data S1-S3 according to the brightness of plural stages based on the detected result of the brightness/darkness detection device. The control data S1-S3 are sent to e.g. a control circuit 21 forming the other part of the control means. Then, the control means 21 generates the control signal, e.g. a current signal according to the control data S1-S3 to supply it to the lighting means 22. The lighting means 22 emits the brightness according to the current signal to light the operation part. Thus, the brightness of the operation part is changed according to the change in the environmental brightness.

Title: Multi-access communication system
Inventor: MATSUNAGA YASUHIKO
IPC: H04N7/173
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To assign a frequency band of an incoming channel flexibly and efficiently in the case of ensuring the incoming service quality in the multi- access communication system where a center station assigns dynamically a frequency band of the incoming channel to a subscriber station. SOLUTION: In the case a subscriber station 30 requests the guarantee of service quality, the station 30 sends a service quality request information 210 to a center station 10. The center station, receiving the information 210, sends an identifier assignment information 310to the subscriber station 30 to assign the identifier. When priority of service is high, the center station 10 sends periodically permitted reservation transmission information 410, 411 tohe subscriber station 30 at an interval of a permitted reservation transmission interval 910 to check the presence of reservation information. Wasteful consumption of the incoming frequency band is suppressed by sending periodically the permitted reservation transmission information even when interval of incoming data generated by the subscriber station is dispersed.  Furthermore, the transmission period of the permitted reservation transmission information is adjusted to warrant an upper limit of an incoming delay.

IPC: G01N27/00
Filed: 1986-01-30
Abstract: PURPOSE:To enable the detection of the presence and the amount of rain drops, by providing first and second electrodes at a specified interval on the back of the dielectric body. CONSTITUTION:Dielectric bodies 7 and 7 are arranged facing respective windows 1a and 1b in a case 1. First and second electrodes 8 and 9 provided on the back of each dielectric body 7 are divided into a plurality of sets each formed in a comb-teetch pattern, for example, 3 sets of unit electrodes 8a-8c and 9a-9c. Then, a rain drop sensor 12 thus obtained can sufficiently detect attached state of rain drops according to changes in the electrostatic capacitance (namely, changes in impedance between the electrodes 8 and 9) practically. The electrostatic capacitance attributed to the rain drops themselves can be ignored. In this case, as the electrostatic capacitance between the electrodes 8 and 9 varies roughly in proportion to the amount of rain drops attached to the dielectric body 7, the amount of rain drops can be detected easily based on the electrostatic capacitance.

Abstract: PURPOSE:To enable to perform a simple and high-precise positioning of a mold, by a method wherein an upper and a lower mold are, in a clamping condition, abutted through a liner on abutting members on a bolster plate placed on the lower mold to position it, and after it is secured, the liner is removed. CONSTITUTION:Positioning of upper and lower molds 4 and 2 of a transfer molder 1 is such that the two molds 4 and 2 are brought to a clamping state, and the lower mold 2 may be brought to abut on abutting members 10 and 11 through a liner 17 having a thickness matching the size of the lower mold 2. The center of the lower mold 2 is positioned above a center hole 16, and coincides with an axis line of a plunger 8. Thus, a position relation between the plunger 8 and the pot of the upper mold 4 also becomes appropriate. If, after the two molds 4 and 2 are secured, the liner 17 is removed, a gap is produced between the lower mold 2 and the abutting members, and even if the lower mold expands by heat, it is prevented from being deformed due to the influence exercised by the abutting members, and the center is kept from displacement.

Title: Boron nitride-coated crucible
Inventor: YAMAGUCHI KOICHI
IPC: H01L21/208
Filed: 1986-01-29
Abstract: PURPOSE:To obtain the titled high-strength and inexpensive crucible having excellent adhesion between the substrate and respective layers and capable of preventing the oozing out of impurities by forming a surface layer consisting of thermally decomposed BN on the surface of the crucible substrate consisting of graphite through two specified intermediate layers. CONSTITUTION:The first intermediate layer for sealing a carbon component consisting of Si, B, or their carbides is provided on the surface of the crucible substrate consisting of graphite. The second intermediate layer for relieving the thermal expansion difference consisting of random oriented BN is furnished on the first intermediate layer. The outermost layer of thermally decomposed BN (hereinafter referred to as PBN) is finally formed by the conventional vapor growth method. Since the first and the second intermediate layers and the PBN film are continuously formed, the adhesion between the respective layers is excellent, the oozing out of impurities is prevented, and the release of the films by a heating-cooling cycle can be eliminated. Since the crucible has high strength, the wall thickness can be reduced, and a lightweight and large-sized crucible can be formed. The production cost can be reduced, since the thickness of the PBN layer can be decreased.
