Title: Brush-system mark read system
Inventor: SUZUKI JIROU
IPC: G06K7/06
Filed: 1978-04-03
Abstract: PURPOSE: To make an exact mark read possible independently of chattering generated in mark read signals.  
     CONSTITUTION: In the mark read part, pairs of brushes A 1 , A 2  to N 1 , N 2  formed by conductors are arranged correspondingly to mark rows 2 1  to 2 n  on card 1 respectively; when these brushes are brought into contact with a mark (oblique line part) recorded by conductive recording materials such as a pencil, mark read signal a is obtained. Since chattering is generated in the start part (leading edge) and the end part (trailing edge) of mark read signal a, the leading edge part is detected to decide this part as the start part (leading edge) of the mark read signal if the mark read signal exists at prescribed time T 1  after the leading edge part detection time. Then, the trailing edge is detected to decide to this part as the end part (trailing edge) of  the mark read signal if no mark read signal exists at prescribed time T 2  after the  trailing edge part detection time, thus obtaining output b.

Title: Soundproof door
Inventor: YAMAGISHI FUJIO
IPC: E06B5/20
Filed: 1994-02-14
Abstract: PURPOSE:To easily improve the sound insulation function after attachment of a door panel, by providing an elastic airtight member and a sound-insulating sheet sealing the clearance between the door stop and the door panel in such a way that a part of the airtight member gets in contact with the door panel when the door panel is in the closed condition. CONSTITUTION:When a door panel 3 is closed, a door stop packing 13 presses the rear face of the door panel 3. As a whole, the packing is compressively deformed and the fine 15 is bent to seal the clearance between the door panel 3 and the door stop 9. A sound-insulating sheet 14 is arranged to contact the rear face of the door panel 3 and the clearance between the door panel 3 and the door stop 9 is closed. Further, an air chamber 18 is formed between the door stop packing 13 and the sound-insulating sheet 14. When sounds are generated in the soundproof room I, the sounds are cut off by a sound-insulating sheet and some sound transmission loss arises in the air chamber 16 and the sound is absorbed in the packing 13 and further it is attenuated by the diffracting action at the time when the sound goes to the O-side. In this way, the soundproof door is inexpensively and easily fabricated and the sound-insulating function can be easily improved even after the panel has been attached.

Title: Magnetic disk device
Inventor: YOSHIKAWA NORIO
IPC: G11B21/16
Filed: 1987-02-24
Abstract: PURPOSE:To decrease the distance between disk media and to attain a compact size of a magnetic disk device by securing such a state where the parts except ing those areas having contacts with the disk media of each head are included in the same space when the head is put into a gap formed between adjacent disk media respectively. CONSTITUTION:A flexure 4B containing an upward head 3B is attached at the lower face side of an arm 5 together with a flexure 4A containing a downward head 3A attached at the upper face side of the arm 5 respectively with a distance secured between both flexures so as to avoid a mutual contact between both heads 3A and 3B. When both heads 3A and 3B are set between the disk media 2A and 2B, it seems as if the recording/reproducing surfaces were provided on both upper and lower face sides of a single head as long as those heads 3A and 3B are viewed horizontally from the vertical direction against the access directions of both heads 3A and 3B. Thus the distance is minimum between adjacent disk media and therefore a compact magnetic disk device is obtained.

Title: Liquid crystal device
Inventor: NAEMURA SHIYOUHEI
IPC: G02F1/133
Filed: 1983-03-10
Abstract: PURPOSE:To display a large picture with high density which is thermally written at a high speed by writing the picture by transparent picture elements while using light scattering state as a background. CONSTITUTION:A liquid crystal substance 26 has a spontaneous spiral array because it contains liquid crystal having a cholesteric phase, and the dielectric constant is positive in case of an electric field having low frequency less than fc and negative in case of an electric field having high frequency more than fc because it contains dielectric constant dispersion type nematic liquid crystal. The main component is a smectic liquid crystal having positive dielectric constant anisotropy. If a high frequency is applied to the liquid crystal, a light scattering state takes place and the state is accumulated also after removing the electric field. The optical scattering state is not changed even if low frequency electric field less than 10<5>V/cm is applied, but if laser light is irradiated under the electric field and the liquid crystal is transferred up to liquid phase, the smectic phase after removing the laser light is turned to a transparent state. The written picture can be erased by applying a high frequency and partial erasing is also available.

Title: Controlling method of reactive power compensated cycloconverter
Inventor: TANAKA SHIGERU
IPC: H02M5/27
Filed: 1980-03-28
Abstract: PURPOSE:To constitute a control system of satisfactory follow-up performance, by seeking a circulating current value to be passed to a cycloconverter by operating a phase control signal and a detected value of load current. CONSTITUTION:Output voltage of a positive-group converter SS-P and output voltage of a negative-group converter SS-N in a condition almost equiligrated by a  load terminal. A sine value of ignition control angle is sought by multiplying a constant over an output signal of an amplifier K2 of a load current control circuit by an amplifier Kalpha. A limitter circuit LIM decides the upper limit and lower limit values of the signal of the amplifier Kalpha. An output signal of an absolute value circuit ABS of a load current IL is put into an adder A7, and the output is put into an adder A8 through an amplifier KQ. A circulating current Io passes following a circulating current command value which is an output of the adder A8. If magnitude of the load current IL and ignition angle are changed, the circulating current command value is varied accordingly, and the circulating current is controlled.

Title: Resonance tunneling transistor
Inventor: IMAMURA KENICHI
IPC: H01L29/73
Filed: 1988-02-23
Abstract: PURPOSE:To improve current gain and reduce base resistance, by forming a base layer by making use of InAs and forming a resonance tunneling barrier by making use of InAlAs and InGaAs. CONSTITUTION:i-type InAlAs 5 and 7 and i-type InGaAs 6 are put on n-type InAs 15 and a collector barrier is formed by i-type InGaAs 14. InAs has separa tion energy of 0.8eV or more between GAMMA and L troughs. As it is larger than separation energy of InGaAs, that is 0.55eV, it becomes harder for InAs to receive trough scattering to an L trough when InAs taken as a base. Further, InAs has a large mobility which is about 1.5times that of InGaAs and then, base resistance becomes small. Moreover, as the collector barrier is made by an i-type GaAs layer 14, even trough scattering in the barrier becomes harder to receive scattering in comparison with the barrier of conventional InAlGaAs. This configuration expands an energy where electrons can reach a collector and emitter current gain increases and has a high speed property. Further, as a collector barrier layer is composed of three elements, a resonance tunneling device which is superior controllability is obtained.

Title: Developing bias voltage control unit of electrophotographic copier
Inventor: KOBAYASHI YUUICHI
IPC: G03G15/06
Filed: 1979-04-05
Abstract: PURPOSE: To perform bias voltage controlling according to the actual ground potential and make possible the constant-density and sharp copying irrespective of image ratios by regarding the minimum voltage of the latent image potentials detected by boosting and dropping means as ground potential.  
     CONSTITUTION: When the switch RS 3  connecting to a boosting resistance R14 is closed for a fixed time before a sensor 11 opposes to the latent image of a photosensitive drum 13, a capacitor C 4  is charged up to the voltage by which the maximum bias voltage is applied to a main electrode 13. Thence, when the latent image of the drum 13 and the sensor 11 oppose, the latent image potential detected is impedance-converted by an FETQ 1  and is applied to the negative side terminal of a voltage-dropping diode. If the pontential is below the voltage of the capacitor C 4 , the voltage of the capacitor C 4  corresponds to the minimum surface potential through discharging. With the voltage which is regarded as a ground potential as a reference, the bias voltage is controlled by way of a transistor Q 4 , Zener diode ZD 6 , etc. Thereby the sharp copy of a fixed density whose image density does not decrease is made irrespective of the large and small of the image ratios.
