Title: Light receiving circuit
Inventor: ONO HIROSHI
IPC: H04B10/564
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent errors and to always receive the stable optical signals regardless of the receiving levels of a photodetector. SOLUTION: A light receiving circuit consists of a photodetector 1 which receives the optical signals and converts them into the electric signals, a preamplifier 2 which amplifies the electric signals, a transistor TR 3 which has its collector connected to a power supply that supplies the power voltage and receives the amplified signals at its base, a resistor 6 which is connected to the emitter of the TR 3 via one of its both ends with the other end grounded, and a variable capacitance means 10 which is connected in parallel to the resistor 6 and has the inter-terminal capacitance that is reduced as the inter-terminal voltage level of the resistor 6 rises. The means 10 can use a variable capacitance diode which is connected in parallel to the resistor 6 with its cathode turned to the emitter.  The capacitance of the diode 10 varies when the inter- terminal voltage varies in response to the light receiving level. As result, the signal waveform has no ringing despite a high light receiving level.

Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To produce an imitation stone resembling a natural stone at a reduced cost by molding and baking a specific mottled patternforming material and body soil used as raw materials. SOLUTION: Water is added to stone granules 1 produced by crushing stone into desired grain sizes, and they are mixed. For example, in the case of granite-like imitation stone, granules of KOUKASEKI (a kind of rhyolite pumice) having grain sizes of 10-60 mesh/SUN (unit of length, almost same to inch) are used as raw material, and they are vitrified by baking. Further, the stone granules 1 are used in an amount of 25wt.% based on the final raw material prepared by mixing this moilled pattern-forming material and other body soil, and water is added in an amount of about 6wt.% based on the amount of the stone granules. The stone granules 1, a pigment 2 and a bonding agent 3 are sprayed together at desired ratios, and they are mixed by stirring followed by sufficient drying.  The pigment 2 is selected corresponding to the mottled pattern to be formed, for example, cobalt for blue, chromium oxide for green, iron oxide for granite color, etc. Thus, a mottled pattern-forming material 4 is formed, in which adhesive-attached large blocks A, adhesive-attached small blocks B and independent stone granules 1 free from the adhesive 3 are existing in a mixed state. The final raw material 6 obtained by mixing the resultant moltted pattern-forming material 4 and desired body soil 5 is processed through a pressing process 7 and a baking process 8 to obtain the objective imitation stone 9.

Abstract: PROBLEM TO BE SOLVED: To prevent both old and new images from coexisting in one cycle of an input signal to a composition judging unit by switching the operations of duplexed memories and their read/write operations at a proper timing. SOLUTION: If a memory switching signal N outputted from a memory switching control circuit 17 is logic '0', this device comes into the state where a memory 7 is made exclusive for writing and a memory 15 is made exclusive for reading.
