Title: Optical recording element
Inventor: ICHIMURA KUNIHIRO
IPC: G11B7/24
Filed: 1988-03-30
Abstract: PURPOSE:To obviate the degradation of definition occurring in flowability with lapse of time by providing a liquid crystal layer contg. a dichromatic dye via a molecular layer of a compd. which is reversibly changed in structure by light on a transparent substrate. CONSTITUTION:This recording element has the structure in which a liquid crystal layer 3 is sandwiched between two sheets of the substrates 1 having the monomolecular layers 2 of a photochromic compd. The photochromic compd. causes a change in the structure when a part A thereof is irradiated by light and, therefore, the perpendicular arrangement of this part is broken and the liquid crystal attains the arrangement in parallel with the surface. The anisotropy of the dichromatic dye changes accordingly. Although the part B which is not irradiated by the light is pale in color, the part A irradiated by the light is changed to a dark color and, therefore, the reading of the light information by the transmittance of the light of the wavelength absorbed by the dye is executed. Since the light of the wavelength which does not generate photochromism by selection of the dye, the breakage of the information is obviated. The degradation of the definition by the liquid crystal having flowability with time is thereby obviated.

Filed: 1983-05-04
Abstract: PURPOSE:To fold cloth without applying additional force thereto by allowing a guide bar to be alternately displaced on front and rear positions of a suspension bar every time the cloth is sent out by prescribed length by a feed roller. CONSTITUTION:When a feed roller 2 is driven and a fan is operated, cloth 1 sent out is, passing through between guide bars 3, suspended in front of a suspension bar 6 in a folded form. And, since air from an air outlet 5 is blown downward along the both surface and back sides of the cloth 1, the cloth 1 is pulled down, and in particular since the inside of a folded part is filled with air on one side, the cloth is suspended downward so as not to be wrinkled. When the cloth 1 of set length is sent out, the guide bar 3 is displaced behind the suspension bar 6. Since the cloth is successively sent out, it is now suspended in a folded form behind the suspension bar 6.

IPC: G06V30/224
Filed: 1982-05-10
Abstract: PURPOSE:To shorten precessing time and to improve the efficiency of recognition by discriminating only the data having a specific reflection factor out of read- out dots by a dot discriminating device and comparing the dot pattern of the discriminated dots with a dot pattern stored in a dot recognizing device. CONSTITUTION:Characters and marks are read out by an optical type character reader 10 by combining two kinds of dots having optically different reflection factors and printing a dot matrix. Dots read out by the reader 10 are applied to a discriminating circuit 12, i.e. a dot discriminating device and only the data having the specific reflection factor out of the dots are discriminated. The dot pattern of the dots discriminated by the circuit 12 is applied to a character recognizing circuit 13, i.e. a character recognizing device, which compares the inputted dot pattern with the one previously stored in each storing position of a character pattern table 15 and accesses a character code corresponding to the consistent dot pattern to execute character recognition. Subsequently the recognized character is sent to an external device 16, so that the processing time for character recognition is shorten and the efficiency of recognition is improved.

Title: Butterfly valve
Inventor: KOSAKAI ASAO
IPC: F16K41/02
Filed: 1978-06-29
Abstract: PURPOSE: To prevent the leakage of gas from bearing portion and the deposition of deposites on the bearing portion by inserting between the bearing portion and a valve body a metallic seal ring which tends to open wide radially outwardly by its elasticity.  
     CONSTITUTION: In the case where a butterfly valve is used for controlling the flow rate of exhaust gas, the exhaust gas has a tendency of leaking from around a valve shaft 14 to the outside of a valve main body 13. However, because a seal ring 26 opens wide radially outwardly by its elasticity to engage the valve main body 13 airtight, the exhaust gas cannot leak from around the seal ring 26 through a bearing portion 25. In addition, the seal ring 26 is moved axially outwardly along the valve shaft 14 by the pressure of the exhaust gas, so that its side face 26b comes in airtight engagement with the side face 14e of a groove 14c. Thus, even if the exhaust gas can pass through a clearance C, it cannot pass between the side face 26b of the seal ring 26 and the side face 14e of the groove 14c.

Title: Method and circuit for resynchronization of synchronous series interface
Inventor: KURIFUTON DABURIYU SANCHIETSU
IPC: H04L7/08
Filed: 1993-03-12
Abstract: PURPOSE: To re-synchronize two devices, without the need of a different line or pin between a controller and a peripheral equipment and without substantially reducing a bit transmission speed. CONSTITUTION: A synchronous serial communication link between a controller 14 and a peripheral equipment 12 is re-synchronized by transmitting a series of the bits of a first logic level by the controller 14. The series of the bits are sufficiently long, so as to decode a command word whose entire bits are the first logic level by the peripheral equipment 12. At the time of decoding the command word, the peripheral equipment 12 resets a synchronization circuit on the inside. Then, the controller 14 transmits the single bit of an opposite logic state and transmits serial data thereafter. At the time of receiving the bit of the opposite logic state, the peripheral equipment 12 releases the synchronization circuit from a reset state and starts the decoding of the serial data which are synchronized with the controller 14.

Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a protection circuit for a brushless DC electric motor that can protect the switching element of an inverter circuit, without increasing the size of a protection device. SOLUTION: A circuit between the collector and emitter of transistors Qau- Qaw for protection is connected between drive signal output terminals 6u-6w of a control IC 6, for outputting a drive signal for driving transistors Qu-Qw and Qx-Qz of an inverter circuit 2 and the ground, and the transistors Qau-Qaw are turned on when a DC voltage VB for driving is applied, thus preventing a noise signal from being fed from the control IC 6 to the side of the inverter circuit 2 before a DC voltage Vc for control reaches an operation-enable level. When the DC voltage for control reaches the operation-enable level, a transistor Qb is turned on, thus turning off the transistors Qau-Qaw and canceling a protection operation.
