Title: Noise pulse eliminating device
Inventor: NAKADOKORO TSUGUTADA
IPC: H03K5/1252
Filed: 1984-10-19
Abstract: PURPOSE:To eliminate a noise pulse by connecting a delay time which has a delay time a little bit longer than the pulse width of the noise pulse to the clock terminal of a D flip-flop. CONSTITUTION:A pulse signal inputted to a terminal C is delayed by the delay circuit 2 and inputted to the clock terminal CK of the D flip-flop 3, and the other pulse signal is inputted to the terminal D of the D flip-flop 3. The delay time of the delay circuit 2 is set a little bit longer than the pulse width of the noise pulse and the D flip-flop 3 is clocked with input pulses which are delayed by a time a little bit longer than the pulse width of noise pulses, so only pulses having pulse width longer than the delay time appear at the terminal Q of the D flip-flop 3, so that noise pulses having pulse width longer than said time are all removed.

Title: Magnetic recording medium and its manufacture
Inventor: TOBISAWA SEIICHI
IPC: G11B5/78
Filed: 1983-11-21
Abstract: PURPOSE:To obtain a magnetic tape with a sufficiently low friction coefficient, without adhesion, edge folds and running flaws, and with less jitter and output fluctuation by forming lots of projected or recessed parts to at least one surface of a back coat layer on a support opposite to a magnetic layer and an overcoat layer on the magnetic layer. CONSTITUTION:Lots of projected parts 4 and recessed parts 36 are formed by processing on at least surface side of a back coat layer 32 on the support opposite to the magnetic layer 2 of a magnetic recording medium having the magnetic layer 2 on the support 1 and on the overcoat layer 33 on the magnetic recording layer 2. The adhesion is reduced by decreasing the friction with a guide member and a head or the like on which both faces are contacted by forming a proper surface coarseness, thereby improving various performances such as reduction of jitter, running stability and running durability or the like. In deciding the processing means or a pattern, projected parts or recessed parts are formed to a desired pattern with high accuracy at all times and the surface coarseness control on the support is conducted optionally to a desired pattern and size.

Title: Sequence data processor and computer readable recording medium
Inventor: YASHIRO YOSHINORI
IPC: G10H1/00
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To properly convert the form of the sequence data. SOLUTION: When a user instructs the conversion of the sequence data through a switch group 104, a CPU 101 makes an IC card reader 107 read the sequence data of a conversion object of an IC card 110 to store them in a RAM 103. The conversion is performed classifying to at least two groups by deciding whether or not it is related to the whole performance while successively reading out the even data constituting the sequence data of the conversion object from the RAM 103, and the event data that the conversion is ended are stored in an area secured in the RAM 103. Thereafter, an interval between the event data is studied in group, and when it is larger than a prescribed interval, the dummy event data are inserted, and the interval is made the prescribed interval or below. The CPU 101 realizes the matter by executing a program of a ROM 102.

Title: Control system of device for using microcomputer
Inventor: SAEGUSA TAKASHI
IPC: G06F15/78
Filed: 1992-08-19
Abstract: PURPOSE:To constitute the system so that even when one microcomputer runs away, the runaway of one microcomputer can always be recovered by resetting it by the other microcomputer, and a smooth operation can be continued even on the way of sequence. CONSTITUTION:In the case an MCU 2 is running away by a certain cause, a periodical signal by a terminal P24 comes not to be outputted. Thus, an MCU 1 checks whether a communication to the MCU 2 exists or not, and unless the communication exists, whether a watch dog timer is overflowing or not is checked, and if it is overflowing, a terminal P11 is set to L and a Vcc output of a DC/DC converter 4 is turned off forcibly. In this case, since the power source is turned off temporarily, when a main switch SWO is turned on in the next time, a normal operation is started. In this regard, in the case the MCU 1 runs away, reset can be executed since reset is always applied by turning off the main switch SWO. In that case, when the MCU 2 is normal, a release sequence operation, etc., are continued smoothly.

Title: Developer for electrophotography
Inventor: AKIYAMA REIKO
IPC: G03G9/09
Filed: 1990-08-21
Abstract: PURPOSE:To form a high density image even in the case of low contrast by using a two-component developer composed of toner particles and carrier particles with inorg. oxide particles having specified volume resistivity added to the surfaces. CONSTITUTION:A two-component developer is composed of toner particles and carrier particles with inorg. oxide particles having <=10<10> OMEGAcm volume resistivity added to the surfaces. The particle size of the carrier is regulated to 10-500mum and the particle size of the inorg. oxide particles is regulated to 0.05-10% of that of the carrier. Since the inorg. oxide particles having low electric resistance are added to the surface of the carrier, excessive electrification of the toner is inhibited and the movement of electric changes in a contact region to the noncontact surface of the carrier is facilitated. The exchangeability of electric charges is improved, electrification speed is increased and remarkable reduction of the extent of electrification is inhibited even when some toner sticks to the surface of the carrier. Excessive electrification of the toner is inhibited in the early stage of development.

As a result, in the case where the battery is held in a jig 1, the battery is evenly attracted to the inner wall of the jig 1, and held in the non-contact condition inside of the jig 1. Shape- check of an upper and a lower surface of the battery is facilitated, and soiling of the battery by the jig 1 is prevented.

IPC: G02B6/00
Filed: 1986-09-19
Abstract: PURPOSE:To eliminate the need for a guided-out light tracking device by providing at least two reflecting surface parts whose reflecting surfaces are not parallel to each other in a main body made of a light-transmissive material, reflecting light which is entered from an incidence surface repeatedly in the main body, and receiving light entering through an optional direction and changing its direction within a certain range.

The opposite planes 5a and 5b between this incidence surface 3 and the other end surface 4 are reflecting surfaces for light guided in the main body 2 from the incidence surface 3. When light L1 is incident on the incidence end surface 3, the light is reflected inward repeatedly at points (a), (b), (c), (d) and (e) and exit from the main body 2 at a point (f). Similarly light L2 entering through another direction is reflected inward at points a1, b1, c1, d1 and e1 and exits from the main body 2 at a point f1. Those reflecting surfaces are so shaped as to approximate gradually the direction of light to the critical angle to the reflecting surfaces according to the repetitive reflection.

Title: Semiconductor device and manufacture thereof
Inventor: MATSUDA HIROO
IPC: H01L23/522
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To avoid the increase of the wiring resistance and reduction of the reliability due to the plug loss of contact holes by extruding an embedding metal part by the depth of the plug loss from a barrier metal surface. SOLUTION: A first inter-layer film 3 is formed on a semiconductor substrate 1. After forming a contact hole 4 on a diffusion layer 2, a first barrier metal layer 5 is formed on the entire surface until the contact hole 4 is filled up with a first embedding metal layer 6a. It is etched back in an etching gas for the embedded metal to result in the plug loss 7 at the first embedding metal part 6b. The metal layer 5 is etched back by the depth of the plug loss 7 to make the bottom of the plug loss 7 at the metal part 6b flush with the surface of the barrier layer 5. There is no depth difference between through-holes 14 just above the contact hole 4 and usual through-hole 13. This eliminates the increase in the wiring resistance and improves the reliability.
