Title: Magnetic card
Inventor: ARAMA SEISHI
IPC: C09D7/12
Filed: 1989-05-17
Abstract: PURPOSE:To identify a card with high accuracy by forming the surface height of a card substrate uneven, and providing a magnetic layer on an uneven surface. CONSTITUTION:A surface 11a of one side of a card substrate 11 is finished in a condition to be always rough at the time of working the substrate, and the height of the surface is made uneven. On the surface 11a, a prescribed magnetic substance 13 is applied so as to make a surface a specified height. Consequently, the thickness of a magnetic layer 12 formed by the magnetic substance 13 is made different according to the position, and even when information is written with the same intensity, a strong magnetization is executed in a position where the thickness of the polar layer 12 is large, and the weak magnetization is executed in the position where the thickness is small. Namely, the recording level of data is made uneven, and the card identification to utilize the level difference can be executed. Thus, the identification of the card can be executed with very high accuracy.

Title: Manufacture of longitudinally short steel ingot
Inventor: OKAMOTO SETSUO
IPC: B22D27/06
Filed: 1979-09-28
Abstract: PURPOSE: To manufacture a fixed longitudinally short steel ingot without entailing a molding board crack by covering the inside wall of a mold with a heat insulator except a ring-shaped lip part and by specifying the ratios of molding board thickness and molding board weight to poured steel weight.  
     CONSTITUTION: On molding board 1, flat mold 2 is mounted and the inside wall of it is covered with heat insulator 5 except ring-shaped lip part 3 at the inside of the bottom of mold 2. The thickness of molding board 2 should be not less than 350mm, and ratio W 1 /W 2  of molding board weight W 1  to poured steeel weight W 2  not less than 0.7. Melted steel 4 to be poured into mold 2 is solidified radpidly by molding board 2 and ring-shaped lip part 3, minimizing the leakage of melted metal from the bottom of mold 2. Because of heat insulator 5, solidification from the side wall of mold 2 is prevented and because of heat insulator 6 placed over melted metal 4, that from the top of the melted metal is eliminated, attaining unidirectional solidification from the bottom of mold 2. Thus, the cracking of molding board 1 is prevented and the internal quality of the longitudinally short steel ingot is improved.

Title: Syphon breakage valve
Inventor: INOUE AKIRA
IPC: F04B53/10
Filed: 1984-06-20
Abstract: PURPOSE:To simplify constitution by constituting a syphon breakage valve from a valve body, cover, and a paddle. CONSTITUTION:When a pump is started and water flows in a discharge pipe 25, a paddle 23 is titled up to the contact position with a stopper 29, having an installation pin 28 as fulcrum. Therefore, a cover 22 lowers to close the opening port 24 of a valve body 21, and the communication between the inside and outside is cut-off, and a syphon is formed. Since the cover 22 has the weight for suppressing the pushing-up by a syphon forming pressure, the jetting-out of the inide water is prevented. Since the differential pressure from the outside increases after the formation of the syphon, the close adhesion performance between the cover 22 and the valve body 21 is improved, and the breakage of the syphon is prevented in so far as the pump stops operation.

IPC: G01B7/06
Filed: 1982-07-20
Abstract: PURPOSE:To measure the thickness of a powder molding simply and precisely in a press cycle, by providing a positon sensor in the hole of a punch in which the core of a lower die is put, and by detecting the position of the upper end of the core at the bottom dead point of a press ram by the sensor. CONSTITUTION:A detector 29, which is a non-contact type position sensor, is fitted in the upper part of the central hole 22a of the punch spacer 22 of a punch 20, while a contact 27 with a metal piece 27e for position detection stuck to the top part is provided in the hole 16 of the punch 20 and actuated downward by a spring 28. Now, when a metal powder body 40 is packed in a lower die 10 and a press ram 30 is lowered, the upper surface of a core 15 touches the contact 27 and pushes it upward against the spring 28, and a gap E is read at the position of the bottom dead point by the sensor 29. Since a change in the gap E is caused by a change in the thickness of a component with a boss, which is a formed article, the thickness of the formed article can be measured simply and precisely in a press cycle.

Title: Control apparatus for ac elevator
Inventor: SUZUKI SATOSHI
IPC: B66B1/30
Filed: 1988-05-23
Abstract: PURPOSE:To reduce generation of noise due to PWM frequency of an inverter by a structure wherein thermal suffering of the inverter is detected, and pulse duration modulating frequency is lowered. CONSTITUTION:When a start frequency of an elevator is high so that an inverter 3 thermally suffers, heating value of a transistor is increased and temperature of a radiating fin provided in the inverter 3 also rises. Therefore, frequency of a triangular wave is successively lowered in accordance with an output from a temperature detection circuit 12, and switching frequency is switched by low frequency. As a result, switching loss is reduced and the thermal suffering of the inverter 3 is decreased, and therefore the present control apparatus can be also adapted to high start frequency. Moreover, although lowering of the switching frequency permits generated noise to be increased, some increasing of the noise is beside the question since the higher the start frequency is, the larger the generated noise is.

Title: Automatic gain control amplifying stage
Inventor: SUZUKI TOSHIAKI
IPC: H03G3/20
Filed: 1983-07-11
Abstract: PURPOSE:To secure a stable operation for gain control regardless of the output level by setting a gain controller between an output stage and a detecting circuit to keep the signal impressed to the detecting circuit at a fixed level. CONSTITUTION:Signal amplifying stages AMP1-AMP5 are connected to each other in cascade via variable attenuators ATT1-ATT4. The output of the AMP5 is supplied to a detecting circuit DT via a variable resistor RV1 which controls the gain and an AMP6. The output of the DT is supplied to a control circuit CTL via a DC amplifier DCA. The circuit CTL controls attenuators ATT1-ATT5 and keeps the output of the AMP5 at a prescribed level. For instance, the gain of lthe AMP6 is increased to set the input to the DT at about the same level as the conventional input in case the output of the AMP5 is set at a level lower than the convertional input. Since the input level of DT is kept at a fixed level the automatic gain control is possible with stability by the circuit CTL regardless of the output level of the AMM5.

IPC: G06F15/18
Filed: 1993-05-27
Abstract: PURPOSE:To provide a hardware for providing a solution at high speed by using a state change concerning a target function and a state change concerning limit conditions selectively corresponding to a state when solving a limited optimizing problem by using a neural network. CONSTITUTION:One unit 101 is composed of two neurons 102 and 103 and they become the components of the network. Additionally, several neurons 107 for state decision are existent and corresponding to the state of the network, a signal is sent for showing which neuron in each unit is outputted. In each unit, any neuron outputs data corresponding to that signal. Since the state is changed so as to decrease the value of the target function when the state satisfies the limit conditions with sufficient accuracy or the state is changed so as to satisfy the limit conditions when the state is considerably against the limit conditions, the solution can be provided at high speed rather than the case of optimization while mixing both of them in a fixed rate at all times.
