Title: Direct current grounding detection circuit
Inventor: MATSUO YOSHITAKA
IPC: G01R31/02
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a direct current grounding detection circuit which normally detects Rg2 easily without being influenced even by a high resistance grounding in a steady state because of aging of electric facilities of a direct current circuit network. SOLUTION: A means 5 which stores an impedance ratio including a previous high resistance component by simulating a grounding in a direct current circuit already accompanying a high resistance grounding is installed. Moreover, the direct current grounding detection circuit is provided with a grounding state detection means 6 which compares a state where a balance of the stored impedance ratio is lost, thereby to detect a grounding accident when the grounding accident actually takes place.

IPC: A61K9/70
Filed: 1983-12-07
Abstract: PURPOSE:To provide a drug delivery member having the water absorptivity, the skin-moisturizing property, the drug releasability and the adhesivity to the skin, etc. as a pressure-sensitive adhesive, by compounding a water-insoluble polymer having stickiness at normal temperature with a specific water-soluble polymer and a drug for transcutaneous absorption. CONSTITUTION:A water-insoluble polymer having stickiness at normal temperature, preferably an uncrosslinked substance having a glass transition temperature of -70--10 deg.C is compounded with a water-soluble polymer composed of a monomer having one ethylenic unsaturated double bond [e.g. PVA, poly(meth) acrylic acid, etc.] and/or a polysaccharide (e.g. starch, pullullan, etc.) and a drug for transcutaneous absorption (e.g. corticosteroid, analgesic anti-inflammatory agent, etc.), and the mixture is applied as a pressure-sensitive adhesive layer to a carrier to obtain a drug delivery member. The obtained product is essentially free from water, and exhibits unique characteristics by absorbing the moisture of the skin. It has water-absorptivity, drug-releasability, adhesivity, etc., and exhibits excellent drug action.

Title: Adapter for data communication
Inventor: OKIZAKI NAOYA
IPC: H02J7/00
Filed: 1993-09-17
Abstract: PURPOSE:To downsize a device, and to reduce the cost thereof without enlarging capacity of an alternating current/direct current converting circuit by providing a control means and a switch means for cutting charge current when operation of a heavy load circuit is detected. CONSTITUTION:A photo-coupler adapter 16 as an adapter for data communication supplies drive voltage of a main body or the like and charge current of a storage battery to an information processing device through terminals 29, 28. For example, a printer as a heavy load circuit is operated for printing, drive current of a printer flows to an alternating current/direct current converter through terminals 21, 22 in addition to the charge current. When the current at this moment exceeds a capacity of a converter, the output voltage thereof is lowered. A voltage check circuit 27 detects this drop, and controls a switch circuit 24 to open through a microprocessor 27. Consequently, charge current is cut, and the current capacity of a converter is not increased.

Filed: 1983-12-08
Abstract: PURPOSE:To form an ideal electrostatic breakdown preventive diode having small dynamic resistance by deeply shaping a reverse conduction type region so as to form a P-N junction with a buried region. CONSTITUTION:A P type diffusion layer 8A formed at the same time as a P type isolation region 8 is shaped, and a P-N junction 12 is formed between the diffusion layer 8A and an N type buried layer 6 in high concentration. Consequently, the resistance section of an N type epitaxial layer 7 can be removed, and the dynamic resistance of a diode can be lowered. Since the P-N junction 12 is shaped by the high concentration region 8A and 12, withstanding voltage reaches to 30-40V, and withstanding voltage proper as the diode for preventing electrostatic breakdown is obtained. An N type diffusion layer 11 in concentration higher than the epitaxial layer 7 is formed so as to be connected to the N type buried layer 6 in order to further lower the dynamic resistance of the diode and further display a protecting effect, thus also lowering one resistance section R4 of the N type epitaxial layer 7.

Title: Lens barrel
Inventor: OKANO HIROSHI
IPC: G02B7/04
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a lens barrel which is compact and easily produced. SOLUTION: A pin 50 relatively moves along a cam groove 40a and a pin 51 relatively moves along a cam groove 40b. An intersection part 40c is a part where the cam grooves 40a and 40b intersect each other and a through-hole thrusting through to the inner peripheral surface from the outer peripheral surface of a cam barrel 40. When the cam barrel 40 is rotated in a direction shown by an arrow, the pin 50 moves from a 1st position Pa1 to a 2nd position Pa2 and the pin 51 moves from a 1st position Pb1 to a 2nd position Pb2 (intersection part 40c). The pins 50 and 51 are arranged so that they may not come in contact with each other at the intersection part 40c. Therefor, the cam grooves 40a and 40b are overlapped and formed on the inner peripheral surface and the outer peripheral surface of the cam barrel 40.  As a result, because the cam barrel 40 is made short in length and thinned, the lens barrel is made small in size and light in weight.

Title: Cdma system
Inventor: TEN BRINK STEPHAN
IPC: H04B1/707
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To reduce the bit error rate of the system by using a transmitter where a mapper connects in series with an encoder and a bit inteleaver and a receiver where a demapper connects to a bit de-interleaver and a decoder. SOLUTION: A binary random signal that is convolution-coded is fed to a random bit interleaver that interleaves a bit signal in a transmitter. An encrypted bit stream passing through the interleaver is given to a demultiplexer that conducts serial/parallel conversion, where the stream is demultiplexed into N-sets of parallel bit streams. A mapper conducts N-bit-N-bit mapping. The bit streams 1,...N after mapping receive spread processing by binary antipodal channel processing codes (code words 1,..., N) whose length is Nc chip. N-sets of the channel processing codes are usually orthogonal to each other. A receiver is provided with a demapper, which conducts repetitive demapping and decoding after de-spreading.
