Title: Magnetic disk device
Inventor: SUGIYAMA TOKUJI
IPC: G11B20/10
Filed: 1988-12-20
Abstract: PURPOSE:To reduce error data generating frequency by setting a threshold based on the recording characteristics of a magnetic disk. CONSTITUTION:Data written on the magnetic disk 1 is read out by a magnetic head 3, and the presence of an error of the data is decided by a controller 16, and then when an error data is generated due to the inadequate set value of a slice level (threshold) of a gate signal generating circuit 7, an error message is supplied to a microcomputer 18. Then, a data S5 for increasing or decreasing the slice level of the gate signal generating circuit 7 is supplied via a D/A converter 19 to the terminal N3 of the circuit 7, to set the slice level at an adequate value. By this method, even in the case of different recording characteristics, an adequate slice level can be set, thus reducing the error data generating frequencies.

Title: Plasma display panel and its manufacture
Inventor: AKIMOTO YASUMASA
IPC: G03F7/027
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To manufacture a plasma display panel with high definition at good yields by forming all or a part of electrodes, a dielectric material, an insulator, a partition, a phosphor, an electron release improver, and a resistor through the leaving behind of part of a photosensitive peeling development type dry paste film. SOLUTION: A protective film on the photosensitive adhesive layer 54 of a photosensitive peeling development type dry paste film A is peeled to form a layer 54, a dry paste film layer 53, an adhesive layer 52, and a support film 51. The layer 54 is bonded to a glass substrate 61 by pressing and heating, and a photomask 62 with a desired pattern is held close to the film 51 and exposed, after which the film 51 is separated from the substrate 61. Adhesive strength between the substrate 61 and the layer 53 is lowered at the exposed part 54B of the layer 54 and remains high at the unexposed part 54A of the layer, so the film A is developed as it is split onto both sides of the substrate 61. Thereafter, the substrate 61 is baked to form the layer 53 as a sintered paste 63 remaining on the substrate 61.  Thus a plasma display panel with high definition can be manufactured at good yields and at low cost.

Abstract: PURPOSE:To monitor trouble such as the damage of a gear at all times and to improve the reliability and maintainability by providing a 2nd gear and an electromagnetic pickup successively to a 1st gear and an electromagnetic pickup and also providing a comparative warning means. CONSTITUTION:The 1st and 2nd gears 2 and 5 which differ in the number of teeth rotate at the same speed by the rotation of a rotary shaft 1. The 1st and 2nd electromagnetic pickups 3 and 6 which face them output sine-wave output signals S3 and S6 which are proportional to the numbers of teeth and the rotating speed in response to the passage of the teeth 2a and 5a and grooves 2b and 5b. Those signals have frequencies proportional to the number of teeth and the rotating speed and vary with the rotating speed of the rotary shaft 1. Those are converted 4 and 7 into rectangular waves and the output signals S4 and S7 of them are compared by the comparative warning device 8 according to the setting of the tooth number ratio. When they are normal, no alarm is generated, but a signal obtained when a tooth damages is different from the setting and abnormality is judged, so that an alarm is generated.

Title: Device and method for adjusting resonance frequency of angular velocity sensor
Inventor: SATO SEIYA
IPC: G01C19/56
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To improve the productive efficiency of an angular velocity sensor which is composed of a vibrating piece for excitation and another vibrating piece for detection coupled with the vibrating piece for excitation in a vibrating transmittable state and detects angular velocities by utilizing the Coriolis force by appropriately adjusting the resonance frequency of the vibrating piece for excitation in the exciting direction and the resonance frequency of the vibrating piece for detection in the vibration detecting direction. SOLUTION: The mass of either a vibrating piece for excitation or a vibrating piece for detection is changed by vapor-depositing a metal on the piece so that the difference between the resonance frequencies of the pieces can fall within a prescribed range (steps 112 and 122). After the mass is changed, the resonance frequencies of the pieces are compared with those obtained before the mass is changed and, when the variation of the resonance frequency of the piece having the original mass is larger than that of the other piece having the changed mass, the adjustment of the frequency difference is stopped (stops 114-118 and 124-128). Therefore, the very long frequency adjusting work can be stopped according to a prescribed rule when the frequency adjustment is impossible.

Filed: 1988-12-23
Abstract: PURPOSE:To perform satisfactory combustion by jetting the total required fuel jet amount when it is not more than a first jet amount, that is, under a low load, and jetting the fuel jet amount while being distributed to intake and compression processes when it is less than a second and not less than a third jet amount, that is, under a medium load. CONSTITUTION:In a control unit 20, a fuel pressure detected by a sensor 27, an engine speed obtained from a crank angle signal of a sensor 29, accelerator opening angle detected by a sensor 30, etc., are input to compute a fuel jet amount. When the required fuel jet amount is not more than a first jet amount which is a sum of a minimum compression process jet amount for an ignition plug 65 enough to form ignitable air fuel mixture and a minimum intake process jet amount enough to propagate frame, a fuel jet valve 5 is controlled such that the total amount is jet during compression process. When the required jet amount is not less than a third jet amount which is less than a second jet amount enough to form an even air-fuel mixture and not less than the first amount, the total amount is jet while being distributed to the intake and compression processes. Satisfactory ignition and combustion are thus performed.
