Filed: 1989-02-08
Abstract: PURPOSE:To shorten the arithmetic processing time without reducing a dynamic range by providing a speed error arithmetic means to compute a difference between the sum of squares of a low-order bit in rotational cycle information and a reference value set corresponding to tape speed to be controlled. CONSTITUTION:Both reel cycle information Ts and Tt obtained by both cycle detectors 4 and 5 are inputted to an arithmetic processing circuit 14, and the cycle sum SUM1 of both reels is obtained by the arithmetic operation of the sum, and the cycle sum SUM1 is compared with a speed comparison value Lim1. In other words, the difference between the sum of squares (Ts'<2>+Tt'<2>) of low-order (n) bits Ts' and Tt' in each rotational cycle information is computed. Thereby, it is possible to perform sum of squares control with high accuracy without impairing the dynamic range, and to shorten the arithmetic processing time required for that.

Title: Communication equipment
Inventor: ENDO MAMORU
IPC: H04B1/69
Filed: 1989-02-07
Abstract: PURPOSE:To use a convolver as a demodulator by generating the referring carrier signal of the almost same frequency as the central frequency of a received signal, to which AM modulation is executed, detecting a correlative output signal to be outputted from a surface acoustic wave convolver, which obtains correlation between the received signal and referring carrier signal, and demodulating an information signal from this detected output signal. CONSTITUTION:In a transmitter A, AM or FM modulation is executed to an RF carrier signal by the information signal and the RF carrier signal is transmitted. In a receiver B, frequency conversion to an intermediate frequency fIF is executed to the central frequency of the received signal by a local oscillator 10 (frequency fLO) and the converted frequency is inputted to the convolver. The referring carrier signal (frequency fREF) is inputted to the other input port of the convolver. At the time of an AM system, the value of the frequency fLO is set so that the condition of fIF=fREF can be established. At the time of an FM system, the value of the fLO is set so that the condition of fIF=fREF+1/2r, for example, can be established (tau: delay time of the convolver.) Envelope detection is executed to the correlative output signal and the output signal is passed through a low-pass filter 18. Accordingly, a demodulated signal corresponding to the information signal can be obtained. Thus, a communication equipment, for which the convolver is used as the demodulator, can be obtained.

Title: Screwdriver bit
Inventor: TAGUCHI YASUAKI
IPC: B25B15/00
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To improve completeness of close fitting to the plus- or minus-shaped hole of a screw, and wear resistance by thermal-spraying particulate metal over a portion fitted to the hole of the screw or the like at the front end of a screwdriver bit so as to form a plurality of micro-protrusions at its surface. SOLUTION: At a blade part 4, particulate metal is thermal-sprayed between its front end and a blade shoulder part 4A to form a plurality of micro- protrusions 6 at the surface, which become a rough surface (approx. 50 to 70 grains/mm<2> ). The micro-protrusions 6 have various sizes and shapes. When they are fitted to the plus-shaped hole of the screw or the like, the protrusions 6 come into close contact so as to bite the inside surface of the plus-shaped hole. Therefore, when the front end of the bit is fitted in the plus-shaped hole of the screw or the like, the screw or the like sits close to it, thus providing easy tightening work. The presence of the micro-protrusions 6 of the bit blade part 4 increases the come-out torque of a screwdriver bit 1, thus it is possible to prevent generation of come-out.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a solidification process whereby wastes can be recycled into a fuel, and no chlorine gas is produced when the wastes is processed or when the obtained fuel is used, which process comprises mixing wastes containing plastics with a dechlorinating agent, dry-distilling the mixture, solidifying the product into pellets and carbonizing the pellets.

Title: Detector for tape end of tape recorder
Inventor: TOMITA SEIJI
IPC: G11B15/093
Filed: 1982-02-26
Abstract: PURPOSE:To detect a tape end securely regardless of whether a tape run forward or backward, by providing a driving body which drives both reel turntables according to the tape running direction with a friction member which controls a detecting member for tape end detection. CONSTITUTION:In a forward reproduction state, a take-up gear 18 is driven through the rotation of a motor 16 to rotate clockwise in a figure. Then, the take-up gear 18 is rotated counterclockwise in the figure on a rotating shaft 16 to engage with the gear 15 of a right reel turntable 13. For example, a tape end comes and the right reel turntables 13 stops. In this case, the take-up gear 18 engaging with the right reel turntable 13 is also stopped and the detecting member 20 does not receive any pressure by the friction plate 19, so that a trace pin  201 is moved to the outside of a cam groove through the rotation of said cam  wheel 34. The trace pin 20 is therefore locked by an outside lock part 351  through the successive rotation of the cam wheel 34 to detect the tape end.

Title: Apparatus and method for forming image using high gamma photosensitive body
Inventor: IRIE KAZUMI
IPC: G03G15/04
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To vary a gradation pattern by virtue of a means for detecting a sensitivity of a photosensitive body in order to use it even when a characteristic of high gamma is degraded or lost therefrom. SOLUTION: Gradation expression of multiple exposure elements is executed by using a common reference signal and a surface voltage of an exposed region on a photosensitive body is monitored by means of a surface voltage sensor 1303 and is converted to digital data by an A/D converter 1306. The surface voltage data is inputted to a CPU 1307. At that time, when the photosensitive body has a good high gamma characteristic, the data inputted to the CPU 1307 may become 5/31. When the characteristic of sensitivity of the photosensitive body is deteriorated and high gamma characteristic is not maintained, it may become 7/31 because of gradation inverting phenomena. Therefore, it is preferable that a threshold level for sensitivity deterioration is set to 6/31.  It is possible to eliminate the gradation inverting phenomena that is caused by variation of sensitivity of the photosensitive body having a characteristic of high gamma by providing a gradation pattern switching section.
