Title: Clock distributing system
Inventor: TODA YOSHIFUMI
IPC: G06F1/04
Filed: 1980-11-18
Abstract: PURPOSE:To increase the working frequency, by successively delaying the clocks the delay due to the wiring and then distributing then to each of the FFs in accordance with the sequence of the signal flow. CONSTITUTION:A clock (clk) is supplied to a clock terminal C of a flip-flop FF1 through a binary sequence circuit and then to the terminal C of the next FF2 from the first terminal C via a wiring (a). Furthermore this clock is supplied to the terminal C of an FF3 via a wiring (b). A delay time such as several ns is caused through the wirings (a) and (b), and the input signal is transmitted in a sequence of FF1-FF3. Thus the input signal is delayed by the FF1-FF3 plus OR circuits G1 and G2, and at the same time the clock (clk) is also delayed through the wirings (a) and (b). As a result, for instance, the delay time between the inputs of FF1 and FF2 is equivalent to the value which is obtained by subtracting the delay time of the clock (clk) caused by the wiring (a) from the sum of the wiring delay time of the FF1 and the circuit G1.

Title: Key telephone system
Inventor: OKUMURA SENJI
IPC: H04M3/48
Filed: 1985-07-25
Abstract: PURPOSE:To facilitate the calling operation at busy state of a called key telephone set by bringing a caller and a called party in the extension standby state when all extension links are discriminated to be busy based on the content of the 1st memory, storing the result in the 2nd memory and calling both the caller and the called party in response to generation of an idle extension link. CONSTITUTION:Data representing various conditions are registered in advance and stored in a RAM 25 used for the 1st and 2nd memories. Whether or not all extension links are busy is discriminated based on the storage content of the 1st memory RAM 25 storing the state of the extension link in response to the extension call, and when it is discriminated to be busy, a main processor CPU 21 generates a callback tone based on the storage content of the 2nd memory RAM 25 in response to the generation of an idle extension link and a called key telephone set ST generates an extension ring tone. Thus, even when all the extension links are busy, the registration of a call to the called ST is received immediately and the calling to the busy called party ST is much facilitated.

Title: Stone hangup machine using falling load reaction force with deadweight of natural stones
Inventor: MIZUSHIMA YOSHIHARU
IPC: B66C1/42
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a stone hangup machine hanging up natural stones (boulders) simply, moving them safely and quickly to the specified working place, and performing the installing works. SOLUTION: Natural stones (boulders) have a reference diameter of 350±100 mm, and when an external force equivalent to the deadweight of each of natural stones having a mean diameter of 400 mm to its part 200 mm away from the center of gravity of the stone (the part with a fixing pin), a moment expressed by the deadweight of the stone multiplied by 200 mm (distance from the center of gravity to the fulcrum) is generated, and the reaction force given thereby and the deadweight are concentrated on fixing pin 8 at one point, and hanging-up can be made on the principle of three- point supporting stability while a balance is established between the reaction force to the deadweight and moment and the load due to external force. The limits of diameter to allow hanging-up are 250 mm as minimum and 600 mm as maximum.  Object greater than that may be hung up by enlarging and reinforcing the belonging members. The reaction force for hanging-up becomes greater in proportion to the deadweight of natural stones, and it is possible to keep the stability and hangup ability constant at all times.

Title: Manufacture of semiconductor device
Inventor: TANAKA MASATO
IPC: H01L21/306
Filed: 1981-10-13
Abstract: PURPOSE:To increase the dimensional accuracy and to obtain the excellent taper for the titled semiconductor device by a method wherein the first tapered etching which makes progress in horizontal direction on the surface of the material to be etched and the second tapered etching, which makes progress in vertical direction by increasing the etching speed in the exposed region only, are arranged to make progress simultaneously. CONSTITUTION:A thin phosphur glass layer 4 is formed on the surface of a silicon oxide film 2, and a prescribed pattern is formed using a photoresist 3. After a post baking has been performed, a silicon oxide film 2' of high etching speed is formed by performing an ion implantation. Subsequently, when an etching is started and a tapered etching makes progress in horizontal direction, an etching makes progress in vertical direction makes progress too simultaneously. Said etching makes a two-staged tapered form when it reached a silicon substrate 1. Besides, the amount of deviation in measurements against the pattern measurements of the photoresist is reduced when an over-etching is performed. Subsequently, when the photoresist 3 has been removed and aluminum 5 is vapor- deposited, an excellent step coverage can be obtained in every region.

Title: Recording medium driver
Inventor: MIYATA HAJIME
IPC: G11B15/10
Filed: 1984-08-02
Abstract: PURPOSE:To improve the operability only with one motor by combining motor forward/reverse revolutions so as to attain plural operations of a recording medium. CONSTITUTION:A recording medium driver attains plural operations of the recording medium by combining forward/reverse revolutions of the motor. When the fast speed mode is selected from the stop mode for example, a motor 76 is reversed, cams 41, 42 are driven and after the motor is driven from the stop mode to the fast feed mode, the reversing of the motor 76 is stopped. A head displacement lever 11 is turned clockwise to the shaft the same as the transition of the reproducing mode, and an angle turned by the head displacement lever 11 is smaller at the fast feed mode than that of the reproduction mode, and the head base is positioned at the middle position between the reproducing state and the stop state at the fast feeding mode. Thus, the operability is improved only with one motor.
