Title: Radio frequency jamming reducer having honeycomb structure
Inventor: ANDREW M CHANESKI
IPC: H05K9/00
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for reducing radio frequency jamming in an equipment using an expansion metal honeycomb structure. SOLUTION: An undesirable decrease in attenuation of propagated high frequency energy due to a metal honeycomb 3 made using a non-conductive adhesive 8 is prevented by blowing conductive paint against exposed faces 9, 10 of slices of the metal honeycomb structure. By this, the conductivity between sections 6 and 7 of the metal honeycomb structure which are insulated from each other by the non-conductive adhesive 8 is recovered. The paint-blown slices of the honeycomb structure are mounted in a frame 2 or are directly mounted on a wall member of a partition wall through which air is caused to flow for cooling an electronic device. The paint-blown slices of the metal honeycomb structure can be protected from mechanical damages by means of individual grills. Instead of blowing paint, the slices of the honeycomb structure can be dipped in paint.

Title: Silundum plate type heat generating body
Inventor: SUGIYAMA CHIYUUTAROU
IPC: H05B3/14
Filed: 1978-06-07
Abstract: PURPOSE: To obtain the heating body which can uniformly heat the object within the temperture range between the room temperture and 1000°C, and to extend it's life so that it can be appropriate for cooking and room heating by employing the silundum material which is not easily oxidized in high temperture range in the air.  
     CONSTITUTION: Silundum powder is formed into plate shape and sintered to provide the heat generating body with the symmetrical resistance rate positive temperture characteristics within the temperture range 200°C∼600°C of the low resistance rate part of the sintered body. For example, silundum powder of prescribed grain size is added organic binder and formed into plate or pipe shaped block. After being applied the primary and the secondary sinterings, they are cut into the shape and the size which meet the demand, and the electrode and the terminal are mounted on them. The temperture of thus obtained plate type heat generating body rises rapidly when the power is supplied especially because it's coefficient of temperture is small. Also, as the resistance rate is high, it is advantageous in relation with the commercial voltage when used for cooking or heating instruments.

Title: Automatic display switching device
Inventor: YAMAGUCHI HIROYASU
IPC: H03J1/02
Filed: 1981-05-07
Abstract: PURPOSE:To display a frequency and time with excellent operability by displaying the frequency in auto or manual channel selection exclusively and the time normally by one display device. CONSTITUTION:A gate TG2 is opened normally by the output of an FF18 and the output of a clocking part 13 is applied to a decoder 11 to perform the digital display of the time. When a keyboard 15 is operated for manual or autotuning, a gate circuit 17 turns on to set the FF18 and then while the gate TG2 is closed, a gate TG1 is opened. Therefore, the output of a digital tuner part 12 is applied to the decoder 11 to perform the display of a reception frequency on display devices D1-D4. In tuning, a pulse is sent from the tuner part 12 to reset the FF18 and then while the gate TG1 is closed, the gate TG2 is opened to send the signal of the clocking part 13 to the decoder 11 for time display. Thus, the frequency and time are displayed with excellent operability.

Title: Rate-of-change meter
Inventor: UMEOKA TATSUMI
IPC: G05B23/02
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To make a rate-of change meter able to quantitatively notify an operator of the changing state of process value and to improve both safety and cost performance of a plant via its accurate operation by calculating the acceleration of the process change from the changed variable of the process value and the time elapsed and then displaying the calculated acceleration. SOLUTION: An input device 1 inputs the state of a process device as the analog value. A calculation device 2 is connected to the device 1 and calculates the changed variable of process value inputted via the device 1 and also the time elapsed during the calculation of the changed variable. An arithmetic unit 3 is connected to the device 2 and calculates the acceleration (a) of the process change from the changed variable ΔP(P2-P1) and the unit time Δt(t1-t2) of the time elapsed. The acceleration (a) is obtained by dividing the change value P of the process value by the square value of the unit time Δt and by an expression of a=ΔP/(t)2. A display device 4 is connected to the unit 3 and displays the acceleration (a) calculated by the unit 3.

Abstract: PURPOSE:To set variably a frequency band of an oscillation frequency varying with a control voltage with a control signal by applying equivalent variable control to a size of a transistor(TR) being a component of a constant current source with the control signal. CONSTITUTION:With only switches SW1m-1, SW2m-1,...,SWnm-1 turned on, two divided drains of 1st divided TRs of TR circuit sections 101-10n-1 of a preceding stage are connected respectively to each gate of the 1st division TRs 1121-112m,..., 11n1-11nm of the TR circuit sections 1012-10n of succeeding stages and the drain of the two divided TRs 11nm and 11n-1m (12nm and 12n-1m) are connected respectively to each gate of the TRs 1111-111m. This is equivalent to the state that the size of the 1st and 2nd division TRs of the TR circuit sections 101-10n is made larger than that when all the switches SW11-SWnm-1 are turned off. Thus, a current flowing to the 2nd division TR is increased more than that when all the switches SW11-SWnm-1 are turned off and the oscillating frequency extracted from a terminal 15 is increased.

Abstract: PURPOSE:To reduce the generating volume of HC and CO by providing air volume adjusting means for temporarily increasing the intake-air volume fed into an engine cylinder during low speed and low load operation so that fresh air compels residual spreading combustion gas to be discharged so as to enhance the scavenge efficiency. CONSTITUTION:A combustion control device for a two-cycle engine 1 having a stratified combustion area, is specifically provided with air volume adjusting means 8 for adjusting the volume of intake-air introduced into an engine cylinder from an ambient air inlet port 2b in accordance with a depresses degree of an accelerator pedal, an engine rotational speed and the like. Further, a main valve 8a and a subvalve 8b are provided. Further, during stratified combustion in which the opening degree of a throttle valve is low, the air volume adjusting means 8 temporarily increase the volume of air fed into an engine cylinder. As a result, the volume of air (fresh air) into the engine cylinder can be increased during stratified combustion. Thus, the scavenging efficiency can be enhanced during stratified combustion in which the speed and the load are low, thereby it is possible to ensure the stratified combustion.

Abstract: PURPOSE:To avoid abnormal operational conditions, and prevent a compressor and inverter from being broken by a method wherein when the connection of 3 phase AC voltage between an inverter main circuit and the compressor is under a reverse condition, the connection of the 3-phase AC voltage to the compressor is switched over in the inverter so that the connection returns to a normal condition. CONSTITUTION:By a signal D which is input to a characteristic deciding device 21, it is decided whether the time-current characteristics are characteristics at the time of normal operation or characteristics at the time of reverse operation. If the time-current characteristics at the time of normal operation are shown, an output signal E is set at 'L', and terminals (b) and (a) of an output switchover device 22 are connected to terminals (d) and (c), and a wave form signal is output to a compressor 1. Also, if the time-current characteristics at the time of reverse operation are shown, the output signal E is set at 'H', and terminals (e) and (a) of the output switchover device 22 are connected to terminals (f) and (c), and a wave form signal is output to the compressor 1, and a reverse condition of the compressor 1 is changed to a normal condition and operated. As a result, when the connection of 3-phase AC voltage (phase R, S phase, T phase) between an interver main circuit 16 and the compressor 1 is under a reverse condition, the connection is switched over in the inverter so that the connection of the 3-phase AC voltage (R phase, S phase, T phase) returns to a normal condition.
