Abstract: PURPOSE:To produce a thin film free from the grains of vapor deposition material and excellent in film quality by hermetically sealing a powdery vapor deposition material in an evaporation source having a porous part through which only the vapor of the vapor deposition material is allowed to pass and then subjecting this vapor deposition material to vacuum deposition. CONSTITUTION:In a vacuum vessel 51 having an evacuation system 53, a powdery vapor deposition material is placed in a boat 40 and heated and evaporated via the boat 40, and the resulting vapor is vapor-deposited onto a base material 55 to form a thin film. In the method for producing the above thin film, the vapor deposition of the above vapor deposition material is carried out by hermetically sealing this vapor deposition material in an evaporation source having a porous part through which only the vapor of the vapor deposition material is allowed to pass. This evaporation source 31 can be constituted, e.g. by blocking a main body part 33 consisting of ceramics as the porous part and ceramic lid bodies 35 at respective openings at both ends of the main body part 33 with a ceramic adhesive 37. By this method, only the vapor of the vapor deposition material can be passed through the above porous part, and a thin good quality film free from contamination with the grains, etc., of the vapor deposition material can be formed.

Abstract: PURPOSE:To attain the communication of multiplexed audio signal and data without use of an expensive audio signal compression technology employing complicated and sophisticated algorithm in the system dealing with 64bps PCM audio signal and data with an ISDN. CONSTITUTION:An ATT 6 attenuates an analog transmission data signal 8 into a level at which code select bits are unchanged and inputs the attenuated signal to a CODEC 5. An AMP 7 amplifies an analog signal from the CODEC 5 with an inverted gain of the ATT 6 and decodes the signal to provide an output of an analog reception data signal 9. A MUX 3 inserts 8kbps transmission data to a most significant bit being a code select bit of a PCM signal being an output of the CODEC 5. A DMX 4 demultiplexes 8kbps reception data inserted to the most significant bit of the code select bit at a pre-stage of the CODEC 5 to set the code select bit of the PCM signal to be an unchanged value identical to a value obtained by decreasing the level of the code select bit of the PCM signal.

Title: Image processor
Inventor: TAKAHASHI SADAO
IPC: H04N1/409
Filed: 1994-02-28
Abstract: PURPOSE:To detect a character edge on various surface paper sheets with high precision by revising a criterion of a character edge detection means depending on a surface elimination quantity to be set. CONSTITUTION:A discrimination circuit 7 discriminates an image attribute as to whether a picture element of interest indicates a character part or a pattern part based on a tentative character part picture element in an AND circuit 6. In the discrimination processing of the image attribute, a character edge is detected by expanding the tentative character part picture element from an internal picture element of the character part into a character background part so as to discriminate the character part thereby including the background part of the character. Furthermore, a surface elimination quantity is set depending on a content of the original to a surface elimination quantity setting means 9. Furthermore, a threshold selection section 8 selects a binarized threshold level with respect to an original used by a binarization processing circuit 1 based on the surface elimination quantity set by the surface elimination quantity setting means 9. In this case, the character edge detection means revises a criterion for detecting a character edge based on the set surface elimination quantity.

Title: Clock signal converting circuit
Inventor: MATSUOKA TAKESHI
IPC: H03K5/00
Filed: 1989-02-09
Abstract: PURPOSE:To improve the convenience of use by outputting a forced set signal with a set means, using an OR gate so as to OR an output signal of a flip-flop and an external clock signal thereby generating an internal clock signal. CONSTITUTION:A clock signal converting circuit 10 has a NAND gate 11, a flip-flop 12 with a forced set input and an OR gate 13 and the NAND gate 11 acts like a set means. When an external clock signal ECP rises for a period while a control signal CT stays at an H level, a current ICP rises synchronously with the leading. When the signal ECP descends for a period when the CT stays at an L level, the ICP descends synchronously with the trailing. Then the ICP is controlled freely by the CT and a change in the CT for the L period of the ECP is not effected on the ICP. That is, the ICP varying synchronously with the ECP is made at all times.

IPC: B60T8/172
Filed: 1979-03-14
Abstract: PURPOSE: To increase the processing speed of a digital anti-skid control system, by employing interruption processing in microcomputor.  
     CONSTITUTION: Signals from wheel-speed sensor 19 and furnished from input- output circit 121 to CPU 135. Solenoid 25 of actuator and others are connected to the input-output circuit 121. CPU135 includes MPU115, RAM117, ROM119, and two sets of free-running counters 123, 125 and registers 127, 129.

Title: Printed board
Inventor: OZAWA YOSHIJI
IPC: H05K1/11
Filed: 1990-02-08
Abstract: PURPOSE:To facilitate production by arranging a part of wiring patterns by passing them between lead installation pads and reducing the pattern width in such area. CONSTITUTION:A part of wiring patterns 2 are provided by passing them between lead installation pads 1a and a pattern 2a in such area is narrowed. Even when the width of the pattern in the area passing between the lead installation pads 1a is reduced to 0.1mm, it does not cause any functional trouble because, for example, the current capacity of a flat package type IC is generally only 20-30mA and that 1mm pattern width per the current of 1A is sufficient. Thus, a printed board is produced by conventional means without increasing the number of wiring pattern layers.

Abstract: PURPOSE:To shorten testing time by preparing writing data according to writing address information and preparing expected data by comparing reading address information and the expected data. CONSTITUTION:When the data are written to a memory circuit 6, first, a test execution control part 1 sets the address information to an address register 2 and sends a writing control signal through a writing and reading control line 9 to a buffer 5 and the circuit 6. Thereafter, the address information set to the register 2 is sent to an arithmetic part 3 and the circuit 6, and the writing data, for which an operation is executed, are written through the buffer 5 to the circuit 6. On the other hand, when the data are read, the control part 1 sets the address information to the register 2, and the arithmetic part 3 divides the address information and sends the information to be obtained to a data comparing part 4 as the expected data. Thereafter, the data read from the circuit 6 are compared with the expected data at the comparing part 4, and the quality of the read data is decided by the compared result obtained by comparing the read data with the expected data. Thus, the testing time can be shortened.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To perform a highly efficient operation by controlling an adsorption time and a regenerative time according to a signal of an air state detecting means for detecting temperature and humidity of dehumidified air before processing. SOLUTION: Inside or in the vicinity of an air inlet 4 for dehumidification is installed an air state detecting means 11 for detecting temperature and humidity of air before entering a dehumidifier. Information of the air state detecting means 11 is transmitted to a control means 12. The control means 12 compares the quantity of water operated from temperature and humidity in a bathroom detected by the air state detecting means 11 with the quantity of water set inside, and sets a time used for a regeneration process according to a difference thereof. Namely, in the case the quantity of water is less than a set value, a shorter execution time of a regenerative process is set, and in the case the quantity of water is more than the set value, a longer execution time of regenerative process.  Conversely, a similar effect is obtained by changing the time for adsorption process according to the quantity of water contained in the air in the bathroom.
