Title: Internal-combustion engine
Inventor: ENDOU MAKOTO
IPC: F02D13/04
Filed: 1982-08-30
Abstract: PURPOSE:To increase an engine brake force, by installing an air sealing chamber, interconnecting the inside of a combustion chamber, in a cylinder head and making a valve at the opening part open in time of operating an exhaust retarder. CONSTITUTION:An air sealing chamber 7 interconnecting a combustion chamber 4 is installed in a cylinder head 3 having an exhaust valve 6 and a valve 8 is installed in the opening part as well. A throttle part 11 is installed in the air sealing chamber 7. The valve 8 is usually closed up by dint of a spring 9 but, in time of operating an exhaust retarder, is opened for operation by means of a solenoid 10. With this, both the combustion chamber 4 and the air sealing chamber 7 come into a state of being interconnected with each other whereby air inside the combustion chamber 4 flows in and out the air sealing chamber 7 together with up and down motions of a piston, producing pumping resistance there due to an action of the throttle part 11 and performing an engine braking action, so that braking force in time of operating the exhaust retarder is increased.

Title: Display method for stereoscopic video image
Inventor: TANAKA YUJI
IPC: H04N13/04
Filed: 1988-06-17
Abstract: PURPOSE:To attain observation for a long period and to obtain a sense of stereoscopic sense sufficiently by converting a polarized axis of a liquid crystal cell attended with the changeover of a picture of a CRT earlier by a time nearly a half the delay time of the liquid crystal cell required for the conversion. CONSTITUTION:A display left picture DL and a display right picture DR displayed on a CRT 1 are repeated alternately at an interval of a display time T1 and a drive voltage V1 is applied intermittently to a TN liquid crystal cell in response thereto. In this case, in the changeover of the display left picture DL having the delay time T2 into the display right picture DR, the drive voltage V1 is interrupted earlier by a half the delay time T2, that is, T2/2. Thus, the rotation of the polarized axis of the TN liquid crystal cell is started when the display left picture DL is still being displayed and the display left picture DL is switched into the display right picture DR at a position of nearly a half on the way of rotation and the switching is finished at a half the delay time T2 of the display right picture DR, that is, T2/2. Thus, the observation for a long period is attained and the stereoscopic sense is obtained sufficiently.

Title: Workpiece conveyor device
Inventor: KINO YUKITOSHI
IPC: B65G51/03
Filed: 1990-06-07
Abstract: PURPOSE:To prevent workpieces from being overlapped during conveyance by conveying the workpieces with gas flow generated by sucking exhaust so as to allow them slide on the floor surface of a passage. CONSTITUTION:Because of being discharged from a exhaust sucking port 13, gas in a gas lead-in passage 2 flows toward the suction exhaust port 13, and also the vacuum state is generated inside the passage 2. Accordingly, gas in a workpiece passage 1 also flows toward the exhaust sucking port 13 through a slit, and gas flow moving from the conveyance starting end toward the conveyance terminal end is generated inside the workpiece passage 1, so that workpieces W in the workpiece passage 1 are pushed by this gas flow and move toward the conveyance terminal end. In this case, since suction force acts upon each workpiece W from the slit 15, the workpieces W slide on the floor surface of the workpiece passage 1 as they are in the state of being aligned along the slit 15.

Title: Diode
Inventor: KAJIMURA TAKESHI
IPC: H01L29/861
Filed: 1983-08-17
Abstract: PURPOSE:To reduce the series resistance and to improve the mass productivity by forming two holes at the prescribed interval on a high resistance silicon substrate, and filling polycrystalline silicon layers of different conductive types in the holes, respectively. CONSTITUTION:Holes of approx. 3-5mum in depth are formed at the prescribed interval on a high specific resistance silicon substrate 10, an N type polycrystalline silicon 11 including impurity such as As or the like is filled in one hole, and P type polycrystalline silicon 12 including impurity such as B or the like is filled in the other hole. The surfaces of the silicons 11, 12 are formed in the same height as the surface of the substrate 10. After an insulating film 13 is formed on the substrate 10, the impurities are diffused from the silicons 11, 12 on the substrate 10, and an N<+> type region 15 and a P<+> type region 16 are formed at both sides of a high resistance region 14. Thus, since a deep diffused layer can be obtained, the reduction in the lifetime of carrier due to surface recombination can be alleviated, thereby decreasing the series resistance of a diode.

Abstract: PURPOSE:To enable repeatedly read information recording mediums to be read without rearranging them one by one by reversing the read direction of image information and working a mirror image of an image according to the instruction of an instruction means. CONSTITUTION:A control circuit 23 as an reverse means controlls a processing circuit 21 according to a signal from a reverse key 24 as the instruction means and normally controlls to fetch the information from a memory address (m1) in order (a normal mode). Then when the reverse key 24 is pushed, the circuit 23 sets the circuit 21 at a reverse mode which the fetching of the information from a line memory 20 is reversed when it receives the signal showing that a film is reversed. That means, the information is fetched in order of the memory lot number (mn).(mn-1)...(m2) and (m1) in the reverse mode. Therefore, by reversing the fetching order of the information from the line memory 20, the normal information output of the reversed film F can be executed like a normal film.

CONSTITUTION:In case of searching a 'Can', words whose initial letter is 'c' are detected 11 from the beginning of a document, words whose initial letter is 'C' are detected 21, and the word locations of 'code' and 'Cool' are stored respectively in registers 12 and 22. After comparing 30 said locations of the both words, the 'code' is outputted, then the spellings of the 'Can' and the 'code' are compared; since the spellings are discrepant from each other, the following word whose initial is 'c' is detected and thus a 'cat' is stored 12. The 'Can' and the 'cat' are compared 30, their spellings are compared 40, then the following word starting with 'c' is detected and the 'cat' is stored 12. Thereafter, similarly, the locations of the 'cat' and the 'Cool' are compared to obtain the following characters 'can', and further, the locations of the 'Cool' and the 'can' are compared to obtain the following characters 'Cool', next, the 'Cool' and the 'can' are compared to obtain the following characters 'Can', and the locations of the 'can' and the 'Can' are compared, then the 'can' and the search object word 'can' are compared, and thus the location of the former 'can' is outputted as a searched location. The obtained location is submitted to a processing pro gram to be displayed with underline through an editing function. With this constitution, the search time is shortened.
