Title: Boots
Inventor: OGAWA TAIDO
IPC: F16J3/04
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To mount a cylindrical boot on objects to be attached having different outside diameters in a general-purpose manner by forming a split part continuously from a first ring part to a second ring part of the cylindrical boot and forming an upper tongue part and a lower tongue part on both side fringes forming the split part. SOLUTION: A cylindrical boot 11 is constituted in such a way that a first ring part 13 and a second ring part 15 are formed at its both ends and a split part 21 is formed continuously from the first ring part 13 to the second ring part 15. A plane 30 to which a split line 22 of the split part 21 and a line connecting a central part 13a of the first ring part 13 to a central part 15a of the second ring part 15 belong exists to form an upper tongue part 23 and a lower tongue part 25 at both side fringes 27a, 27b forming the split part 21. They are mutually and vertically overlapped along both side fringes 27a, 27b. Consequently, the boot 11 can be mounted on objects to be attached having different outside diameters in a general-purpose manner.

Title: Program copyright protecting method and device
Inventor: TANABE KATSUYOSHI
IPC: G06F21/14
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To sufficiently protect a program copyright by converting inputted copyright information into a specific character string, embedding the specific character string into an output of an acquired source format program and outputting a source program in an output format. SOLUTION: When a source format original program (a) is inputted to a converting part 110, the part 110 acquires the input of a conversion key and copyright retrieval information from a user, and outputs a specific character string which can be read about an input character by using a conversion key (cipher) function but can not be understood to an embedding part 120. In such cases, which conversion type to be selected depends on a conversion key that is inputted by the user. Next, the specific character string is embedded in an output designating part (designation position) so that the part 120 may show a source format program (b) in the read source format original program (a). This makes it difficult to understand copyright display.

IPC: H01L21/3213
Filed: 1979-08-13
Abstract: PURPOSE: To arrange an electrode window and wirings with high accuracy by irradiating electron beams having different strength respectively at an electrode window and wiring formation parts wherein a resist mask having partially different thickness is formed.  
     CONSTITUTION: A PSG2 and a resist 3 are stacked on an Si substrate 1 formed an element. An opening window section 4 is irradiated by the optimum amount of irradiation of 30%. Then, a wiring formation section 5 is irradiated by the amount of irradiation of about 70%. The window 4 will be opened by development and a resist 3 will be left at the wiring section. Al on the resist 3 is lifted off by evaporating an Al film 6. In this composition, the repetition of mask alignment becomes unnecessary and the positioning by electron beams is extremely exact. Therefore, an electrode window will be formed with high accuracy equivalent to self-matching. Furthermore, it is effective even if two kinds of resists having different solubility to developing solution are stacked.

Title: Control method of building control system
Inventor: KANEKO TAKASHI
IPC: G06Q50/16
Filed: 1984-05-23
Abstract: PURPOSE:To allow a system which controls, monitors, and records various facilities in a building to control processing after power recovery excellently by detecting a power failure time and selecting or changing the process after the power recovery. CONSTITUTION:When the power failure of a power unit AVR is detected, that is reported to a CPU and current time T1 is read out of a timer CLK according to the program stored in a memory ROM and stored in a memory RAM. A pulse counted value M and the time T1 which are stored previously are held continuously by a storage battery BAT during the power failure. when the system recovers from the power failure a certain time later, the CPU reads current time T2 out of the timer CLK and compares it with the time T1. Then when it is judged that the power failure lasts for the short time and there is no problem to the system, the counting operation is continued without initializing the counted value M. If it is judged that the power failure continues for a long time and there is a problem, the counted value M is initialized and pulses are counted from the beginning. Thus, the processing after power recovery is performed properly.

Servo motors 12, 6 and 16 are controlled by the numerical value control section 42 through respective X, Y and Z axis drivers 45, 46 and 47. The movement amounts are counted by inputting signals from encoders of respective axes into the numerical value control section 42 to control the coordinate.  The control for stopping the rotation of a rotating motor 31 of a turret head and a cutter driving motor 19 is carried out by the arithmetic and logic unit 41 through relays 43 and 44.

Title: Synchronizing circuit
Inventor: NARISAWA SADAYUKI
IPC: H04N5/073
Filed: 1986-05-02
Abstract: PURPOSE:To prevent deviation on a screen by regarding a timing deviated from the estimated timing of the synchronizing signal of an asynchronizing system by the deviation in a deviating direction from a window as the synchronizing signal timing of the next asynchronizing system so as to control the synchronizing system. CONSTITUTION:When an external horizontal synchronizing signal EXHSY is deviated from a window adjacently, the signal is shifted by a prescribed quantity in a direction deviating the window for correction. When the signal is deviated furthermore, the external horizontal synchronizing signal EXHSY is corrected so as to come to the center of the window. Thus, it is possible to lock the window to the center of jitter and even when the jitter exceeds the absorption limit, the change in the period of a horizontal synchronizing signal in the synchronizing system is less and the period changes smoothly, then the deviation on the screen is unremarkable.

Title: Inputting method of nonstandardized charcter for chinese character input device and pulse generating circuit used therefor
Inventor: NAGAYAMA TADAHIRO
IPC: G06F3/023
Filed: 1979-08-14
Abstract: PURPOSE: To accomplish a simple inputting of nonstandardized characters by applying pulses to an upcount or downcount input terminal through a given circuit in the number equeal to the coodinate difference between the characters on a character panel the nonstandardized characters.  
     CONSTITUTION: Selector switches 34 and 35 are so interlocked that the switch 35 is closed quicker than the switch 34. When the switches are turned to contacts 34b and 35b, one pulse is sent to a clear terminal 23 of a counter 21 from a monostable multivibrator 33 to clear the counter 21. Pulses from an a stable multivibrator 32 are inputted into the counter 21 with the result that the input terminals of a NAND circuit 30 goes to "1" whereby the counter 21 is halted. The number 47 of pulses from an AND circuit 31 is added to bring the number 32 preset of the up/down counter to 79 through a contact 35b so that the second standard chinese characters are replaced by the nonstandardized characters. Accordingly, the nonstandardized characters can be inputted simply at a low cost.

IPC: G11B15/093
Filed: 1980-07-25
Abstract: PURPOSE:To avoid a fault due to the sag of a tape, by securing the performance mode through detecting the stoppage of a reel shaft. CONSTITUTION:A cassette 1 is loaded after a power supply switch 53 is turned on, and thus a motor switch 54 is turned on to start the driving. In this case, a feed reel shaft 9 is stopped by a rotation preventing lever 47, and a take-up reel 8 is also stopped as long as a tape has no sag. Thus a driving plate 19 of a reel shaft rotation stop detector 18 is positioned at the center. Accordingly a sliding plate 23 is slided back to turn a chain lock lever 35, and the locking mode of a start gear 32 is cancelled to be turned. Thus a start lever 40 turns, and a head substrate 2 slides to release the forced stoppage of the reel 9. In case when the tape has a sag, the shaft 8 takes continuously up the tape until the tape has no sag. Meanwhile the plate 19 is turned clockwise, and thus a bent bar 39 of the plate 23 is not allowed to contact with the lever 35. Thus the sag of the tape is eliminated.
