Title: Magnetic recording device
Inventor: OGATA SHIGEYUKI
IPC: G11B5/09
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by making the gap length of an erasing head small. SOLUTION: The magnetic layer thickness of a target magnetic recording medium 13 set to 0.2μm or lower, an erasing head 16 for recording an erasing signal is placed before recording heads 12 and 13 for recording digital signals and the output of a signal generator 15 for generating a signal having a wavelength shorter than the shortest recorded wavelength of a digital signal is inputted to the erasing head 16. The erasing head 16 has a gap length proper for short wavelength recording and a recording current for obtaining a necessary magnetic field is small. Also, since an erasing signal is an unnecessary frequency during reproducing, no influence is given to signal detection.

Title: Precast concrete column member
Inventor: ABUKAWA MASAHIRO
IPC: E04C3/34
Filed: 1990-11-09
Abstract: PURPOSE:To facilitate formation of a mortar discharge port by arranging the mortar discharge port of a sleeve type joint for a core reinforcing bar in a level higher than that of the upper end of the sleeve type joint of a peripheral reinforcing bar when a sleeve type joint is embedded in the lower end part of a column. CONSTITUTION:Sleeve type joints 1a and 1b are coupled to the lower end parts of a peripheral reinforcing bar 8a and a core reinforcing bar 8b, respectively, arranged to a PC column member 7. When a mortar discharge port 10a of the sleeve 1a and a mortar discharge port 10b of the sleeve 1b are formed, the position of the discharge port 10b is located in a level higher than that of the upper end of the joint 1a. A reinforcing bar through-hole 15 is formed in the lower end of the joint 1b. When the column 7 is connected to a lower column, forms are located around a joint between the columns, filling with mortar is effected until the mortar flows over the discharge ports 10a and 10b, and the mortar is cured for integral formation. This constitution facilitates formation of the discharge port of the core reinforcing sleeve without locating a peripheral reinforcing bar sleeve therebetween.

IPC: G11B15/467
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing device excellent in tracking control also at the time of trick play. SOLUTION: This device is of a helical scan type by a multi-segment system for recording and reproducing a recording signal formed by superimposing a tracking pilot signal of an ATF system making a pilot signal of a frequency f1 and a pilot signal of a frequency f2 to be alternately recorded at every two record marks on digital data of such main signals as one frame of picture information and speech information, etc., divided corresponding to the predetermined number of record marks.  In this case, when a reproducing operation is performed by running the tape at a running speed of (4m/n) times (n, m are positive integers) tape running speed at the time of recording operation, a running phase of the magnetic tape T is controlled by generating tracking control signals once every n-pieces of record marks based on the pilot signal for tracking and holding them (31-34), and supplying the tracking control signals to capstan control systems (3, 9-11, 30, 48).

Title: Press
Inventor: JIEFUERII JIEI FUOOKINSU
IPC: G03G15/02
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a printing machine having high-reliability devices re- electrifying a photoreceptor for minimizing the transfer of background toner. SOLUTION: This printing machine contains a charge holding face in the form of a photoreceptor belt 10 and corona generating devices 36, 51, 61 re- electrifying the charge holding face. After an image region is developed by discharge region development, the photoreceptor 10 contains the first level which is the voltage level of an electrification region, i.e., a background region, and the second level which is the voltage level of a discharge region, i.e., an image region. The corona re-electrifying devices 36, 51, 61 re-electrify the toner image region and the background region of the photoreceptor 10 to the intermediate electrification level between the first level and the second level.  The intermediate re-electrification voltage level prevents the transfer of the background toner to the final support to ensure that the electrification level of the background toner is not inverted to the same polarity as that of the toner in the image region.

Abstract: PURPOSE:To provide a tape for printing in which the tape and characters, etc., printed on the tape can be printed clearly without deterioration and a tape cassette containing the same tape, discoloration even if it is exposed with an ultraviolet ray. CONSTITUTION:Ultraviolet ray absorbent is contained in a base material sheet 1 of a tape T for printing, and a heat sensitizer layer 2 in which a color developing reaction is effectively generated by a heat generator of a thermal head without influence of atmospheric temperature is formed on the sheet 1. Thus, both a printed part and a nonprinted part of the tape T, V are effectively protected against an ultraviolet ray thereby to prevent the printed part from being faded as much as possible and to also prevent the nonprinted part from being discolored (yellowed). Characters, etc., are printed with clear and stable printing quality without influence of the atmospheric temperature to the layer 2. Further, a printing ribbon is eliminated to simplify a structure of a tape cassette.
