Title: Shoring of load
Inventor: SAWADA SATOSHI
IPC: B65D21/02
Filed: 1993-03-19
Abstract: PURPOSE:To prevent load crumbling and easily separate loads from each other, by providing a peelable adhesive layer chiefly made of fine spherical particles adhesive component on at least one of contact surfaces of the loads. CONSTITUTION:A peelable adhesive layer chiefly made of fine spherical particles adhesive component is provided on at least one of contact surfaces of mutual loads, when storing or handling a plurality of loads. Cardboard boxes or the like provided with a peelable adhesive layer are temporarily stuck to vertically or laterally adjacent cardboard boxes by means of the adhesive layer. In the temporarily stuck part, a large resistant force generates against shifting on the plane by the coagulating force of the binder component to prevent load crumbling. Since the adhesive component of fine spherical particles has only a small contact area with the stuck body, the face has little resistance against the vertical peeling force to the face applied with the adhesive, loads like cardboard boxes can be easily separated.

Title: Detector of revolving direction
Inventor: HASEGAWA YOSHIHISA
IPC: G01P13/04
Filed: 1981-04-21
Abstract: PURPOSE:To ensure an assured detection of the revolving direction with a simple constitution, by driving a D type flip-flop with the pulse signal corresponding to a detection output having a cycle corresponding to the number of revolution and a phase different by pi/2. CONSTITUTION:Detection pulses (c) and (d) having a cycle corresponding to the number of revolutions given from waveform shaping circuits 4 and 5 with a phase different by pi/2 are applied to both D terminal and clock terminal Cp of a D type flip-flop FF6. Accordingly the FF6 is triggered by the pulse (d) in the forward turn mode when the pulse (c) is at a high level. Then the Q output of the FF6 is set at a high level. In the backword turn mode, the Q output is always set at a low level since the trigger timing caused by the pulse (d) is different. Thus the Q or -Q output of the FF6 ensures an assured detection of the revolving direction with a simple constitution.

Title: Method for constituting neural circuit network
Inventor: SUZUKI SHIN
IPC: G06N3/04
Filed: 1990-03-12
Abstract: PURPOSE:To prescribe the form of a function realized by a neural circuit network even at a part, where learn data does not exist, by correcting the amount of updating branch load between respective layers from an evaluation value based on the average curvature of the neural circuit network in a learning process according to an inverse error propagation method for constituting the neural circuit network. CONSTITUTION:By using the output of an output layer 7, a load correction part 22 calculates the correction value for the amount of the load update, which is calculated by a load calcula tion part 18, of a branch 12 between an intermediate layer 8 and the output layer 7 according to the valuated value based on the mean curvature. Similarly, by using the output of the intermediate layer 8, a load correction part 23 calculates the correction value for the amount of the load update, which is calculated by a load calculation part 21, of a branch 10 between an input layer 6 and the intermediate layer 8 according to the mean curvature. Here, use is made not only the square errors of a teaching signal and the output of the neural circuit network but also a reference based on the mean curvature which is a differential geometrical feature of a curved surface in a multi-dimensional space composed of the functions representing the input/output characteristic of the neural circuit network. Thus, not only the value at a point where the learning data is applied, but also the shape of the function near this point can also be prescribed with a reasonable reference.

Filed: 1983-04-05
Abstract: PURPOSE:To make a mill compact by forming it into a titled one and to reduce an initial investment by performing a rough rolling with four rolls and inserting another rolls to perform a finish rolling with six rolls. CONSTITUTION:In changing a rolling to a finish rolling immediately after completing a rough rolling, an upper work roll 1a of work rolls 1a, 2a is raised by a rolling reduction screw 8 and the lower work roll 2a is lowered by a rolling reduction screw 10, to obtain a space into which upper and lower small diametral work rolls 11, 14 are inserted. After inserting the rolls 11, 14, back up rolls 6, 9 are screwed up and down respectively to bring all the rolls into contact with each other. Because the rolls 11, 14 are used only for the finish rolling, the surface roughennesses of them are remarkably reduced, the surface of a product is maintained always in excellent quality and the product of high quality is obtained.

Title: Radio wave absorber
Inventor: SHIMIZU KATSUAKI
IPC: H05K9/00
Filed: 1989-03-14
Abstract: PURPOSE:To enable absorbing radio waves in a high-frequency band and those in a low-frequency band and maintain the stable electric wave absorption characteristic for a long time by making conductive films of surface resistivity gradually decreasing toward the surface of a tile. CONSTITUTION:Conductive films 3 are installed approximately perpendicularly to the surface of a tile 2 and arranged in parallel crosses. The surface resistivity of the conductive films 3 continuously changes to prevent the characteristic impedance from rapidly changing and reflect few electromagnetic waves. The surface resistivity gradually decreases from the ends (a) on the sides of incidence of radio waves generated in a room to the tile-side edges (b). Thereby radio waves over a wide band from a low-frequency band to a high-frequency band are efficiently absorbed without moisture absorption and the stable radio wave absorption characteristic is maintained for a long time.

Title: Latch circuit
Inventor: MURAMATSU KIKUO
IPC: H03K3/037
Filed: 1980-05-08
Abstract: PURPOSE:To ensure a good latching even with a single-shot pulse, by latching a data input signal automatically and without any intervention of a latch enable signal after sensing a logic change of the data input signal. CONSTITUTION:When a catch enable signal input terminal is inactive, only a latch enable signal input terminal 2 is effective. When an input terminal 2 is in active, the data input signal supplied to a data signal input terminal 1 reaches directly a signal output terminal 3. When an input terminal 7 is active, the transition of terminal 1 is transmitted to a data signal gate circuit 4 and a latch gate circuit 5 through a catch enable gate circuit 8. Thus the circuit 4 closes and the circuit 5 opens to stabilize the latch circuit. Accordingly a latching is possible although the data input signal is identical with an irregular single-shot pulse and with no consideration given to the timing of the latch enable signal but by securing a use of the input signal itself as a latch enable signal.

Abstract: PURPOSE:To make it possible to delay the first output f1 for T time and to delay the second output f2 for 2T time by adding two signals f1 and f2 to the delay line of delay time T and adding again the second signal f2 to the delay line after frequency conversion. CONSTITUTION:A reproducing luminance signal f1 and a reproducing chrominance component f2 which are inputted to an input terminal 5 are supplied to a 1HCCD delay line 1 through an adding circuit 6. The output of this delay line 1 is added to a LPF2 that transits the luminance signal f1 only and the luminance signal that is delayed 1H is outputted from an output terminal 7Y. Also, the output of the delay line 1 is added to a BPF3 that transits the chrominance component f2 and is frequency-converted to the third signal f2+ or -f0. This third signal is frequency-converted at a multiplication circuit 10 through a BPF4 and is restored to the reproducing chrominance component f2 at a BPF11. Therefore, a double horizontal period delayed chrominance component f2 is obtained at a chrominance component output terminal 7C.
