Title: Optical information reader
Inventor: KANNOU TETSUYA
IPC: G06K7/10
Filed: 1995-03-17
Abstract: PURPOSE: To read not only a matrix code but also a high-density one- dimensional bar code or stack code by reading series of information to be read by providing plural image forming means and two-dimensional image sensors and synthesizing respective pieces of read information. CONSTITUTION: An illumination light source 1 is composed of plural red diodes (LED). The light irradiating from the illumination light source 1 is made incident to a bar code label 5 of a recording medium, on which the bar code of information to be read is printed, proximate to a reading window 6 and reflected on the surface of the bar code label 5. The irradiating light reflected on the surface of the bar code label 5 is converged through the reading window 6 to each lens 2 and the image of the bar code is formed on each two-dimensional image sensor 3. Then, the irradiating light made incident to each two-dimensional image sensor 3 is photoelectrically converted here into an electric signal corresponding to the bar code.

Filed: 1984-03-28
Abstract: PURPOSE:To reduce the number of processes largely by using manufacture through which a P-N junction, a light-receiving surface electrode, a back electrode and an antireflection film in the whole constitution of a solar cell can be formed only through one-time heat treatment. CONSTITUTION:P ions or As ions 9 are implanted to a single-side light-receiving surface in a P type crystal Si substrate 2, and paste 6 for an Al group electrode is screen-printed on the back, and dried. An antireflection-film forming solution 7 is applied on the light-receiving surface, and dried, and paste 8 for an Ag group electrode is screen-printed on the light-receiving surface in a pattern manner. Paste is dried, and the whole is thermally treated for 0.5-60min at a temperature of 600-800 deg.C under a nitrogen atmosphere containing oxygen. Accordingly, the large reduction of cost of a solar cell can be attained because heat treatment processes can be made sharply smaller than conventional methods.

Title: Stroke control device for reciprocating travelling body
Inventor: YAMADA MINORU
IPC: B23Q15/22
Filed: 1989-03-10
Abstract: PURPOSE:To enable the accurate control of stroke by inserting pulse interval with time, and detecting microscopic distance more than the resolution of an encoder. CONSTITUTION:The A phase signal from an encoder detector 65 is generated at every specified distance p of the main shaft quill feed, and measures the pulse generation interval times T0, T1, T2 when A phase signal starts up in few pitches just before the target position at the time the remaining distance h until the target position is converted to time t. And, the time t to travel the remaining distance h is estimated from that generation interval times T0, T1, T2, namely, the time to travel the specified distance, and the position control of quill feed is performed by a resolution that is more minute than the pitch p of an encoder 60, namely, the distance between the detection through holes 62. Thus, more precise stroke control can be performed using encoders that are comparatively low-priced.

Title: Equipment and method for driving sensorless switched reluctance motor
Inventor: JEONG SHEONG-KI
IPC: H02P25/08
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a motor driving equipment having resistance to electric noise and mechanical disturbance by outputting a phase excitation signal by logic/combining a pulse modulation signal generated by a voltage instruction signal and a rotor phase signal. SOLUTION: After receiving an alignment instruction signal from a speed controller 120, a digital firing angle estimating equipment 130 outputs a rotor position signal for applying current to a specified phase to an inverter driving section 140 to allow a rotor to be aligned. After the passage of a specified period of time, a pulse signal is continuously applied to the digital firing angle estimating equipment 130 until the present excited phase is shifted to a previously excited phase. During that period, it is judged from phase current signals of previously excited phases input from a phase detecting circuit 110 whether the rotor has reached a firing angle or not. When the rotor reaches the firing angle, a rotor phase signal is input to the inverter driving section 140 and a phase shifting is executed.  This process is repeated until a motor 160 reaches a preliminarily set starting speed. By this method, a driving equipment having resistance to electric noise and mechanical disturbance can be obtained.

Title: Scan path connecting system
Inventor: YABE MASASHI
IPC: G06F17/50
Filed: 1989-03-10
Abstract: PURPOSE:To reduce the no wiring or the detour wiring, etc., of a signal wire by executing the arrangement processing of a logic circuit based on logical connection information, tracing a scan F/F on the result of this arrangement according to a scanning order determined in advance and obtaining new scan path connection information. CONSTITUTION:An arranging means 3 determines the arrangement of logical elements to constitute a logic circuit based on the logical connection information to be applied to the logic circuit including the plural scan F/Fs. An F/F rearranging means 4 traces the scan F/F on the arrangement, which is determined by the arranging means 3, and derives the order of the scan F/F based on the prescribed scan order on the arrangement stored in a scan order storing means. A scan path reconnecting means replaces the scan path connection information in the logical information with the new scan path connection information according to the calculated F/F tracing order. Thus, the unnecessary detour of the scan path itself and the other signal wiring or the generation of the no wiring can be avoided as much as possible.

Title: Rom with security function
Inventor: WATANABE OSAMU
IPC: G06F21/12
Filed: 1987-03-13
Abstract: PURPOSE:To easily add the security function without considerably changing the circuit scale by collating a key pattern stored in the key pattern storage part of a ROM with an inputted key pattern and deranging an input address to read out erroneous data in case of disaccord between both key patterns. CONSTITUTION:The key pattern preliminarily written in a key pattern storage part 4 and the inputted key pattern are compared with each other in an address deranging part 5. When two patterns coincide with each other, the address inputted to read out data is not deranged and is given to a memory cell to read out correct data. When they do not coincide with each other, the address is deranged and data corresponding to this deranged address is read out, and therefore decoding is impossible. That is, the key pattern is stored in the key pattern storage part 4 of the ROM to eliminate a need of a private controller and to reduce the circuit scale.
