Title: Method for high-precision cutting work of annealed steel
Inventor: HARADA TAKASHI
IPC: B23B1/00
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To improve surface roughness without deteriorating a dimensional precision, in a high-precision cutting work of an annealed steel by c BN tool. SOLUTION: An upper limit of a ratio of a tool is set up at a value so that a theoretical surface roughness calculated from the feed ratio may be in a range from 1/1000 to 2/3 of an objective surface roughness. The range of feed variation between the upper limit and the lower limit is made not less than 0.002 mm/rev and not more than 0.05 mm/rev. Within this range, the amount of change in feeding at one time is prevented from becoming an integral multiple of the original feed ratio, and the feed ratio is forced to change at every work numbers so that the total length of cutting at each time may range from 10 m to 1000 m.

Title: Ink jet recorder
Inventor: KATO SEIICHI
IPC: B41J2/05
Filed: 1988-10-31
Abstract: PURPOSE:To prevent effectively excess rising of an ink meniscus due to electrostatic attractive force without action of the electrostatic attractive force on a surface of the ink and to avoid erroneous fly of ink by a method wherein when all image information within an established printing range of a head body is non-printing data, energy applicating operation of an electrostatic energy applicating means is inhibited. CONSTITUTION:An inhibition means 7 inhibits energy applicating operation of an electrostatic energy applicating means 5 under specific conditions, and avoids discharging operation of ink. An image discriminating means 8 discriminates that all image information within an established printing range of a head body 1 is non-printing data, and sends this discriminating signal to an inhibiting means 7. The inhibiting means 7 inhibits energy applicating operation of the electrostatic energy applicating means 5 within the established printing range of the head body. During this time, idle electrostatic attractive force never acts on the ink 3 in an ink discharge part 25 positioned, within the established printing range of the head body 1. Therefore, an excess pulling up phenomenon of a meniscus by the electrostatic energy applicating means 5 is effectively prevented, and erroneous fly of the ink is avoided.

Title: Stator core of motor
Inventor: SATO MUNETADA
IPC: H02K1/26
Filed: 1988-10-28
Abstract: PURPOSE:To perform winding work smoothly so that no winding conductor will catch on an end face angle at the projected section by chamfering the end face angle when the winding conductor gets into a slot section from an outside circumferential opening section. CONSTITUTION:When a winding conductor is wound around a stator core 1, a winding jig 8 is put on to the outside circumference of the stator core 1. The projection 8A at both ends of the winding jig 8 is then brought into contact with the projected section 4A of an outside circumferential opening section 6 of the stator core 1 and fitted into there and secured. As the projection 8A is smaller than the width of the outside circumferential opening section 6, clearance L is ensured at the outside circumferential opening section 6. The winding conductor is wound around along the winding jig 8 from the projected section 4A side to inside the slot 5. At this moment, the inside of the projection 4A is a largely chamfered angle face section 4C and the dimension of L is enlarged so as to make it easy for the winding conductor to get in, even if the width of the projection 8A of the winding jig 8 is made thin and its height low to keep the strength. The winding conductor can be wound around smoothly without being caught at the angle face section 4C when it gets into the slot section 5.

Filed: 1993-11-01
Abstract: PURPOSE:To automatically improve color reproducibility by discriminating a discharge lamp light source which is inferior in color deduction such as a mercury vapor lamp and a low-pressure sodium lamp. CONSTITUTION:A photosensor 11 photodetects light which is inputted through a camera lens 1 and the photodetected light is photoelectrically converted and outputted to an AC decision part 12. The AC decision part 12 outputs a decision result showing whether the input signal is AC to a color compensation control part 13, which decides that the light source is not a discharge lamp when the decision result indicates DC and performs no special color compensation, but decides that the light source is the discharge lamp when the decision result indicates the AC and outputs a hue and saturation degree control signal for color compensation to a matrix circuit 6, thereby improving the color reproducibility in case of the discharge lamp light source which is inferior in color deduction such as the mercury vapor lamp and low-pressure sodium lamp.

Filed: 1985-12-05
Abstract: PURPOSE:To raise the sharpness of an extreme value of a correlation characteristic by providing an adding circuit for adding successively a weighted coefficient, and outputting its added value as a correlation value. CONSTITUTION:The smaller a difference between a numerical data D4 and D5 is, the larger value of a coefficient is generated by a weighting circuit 49, and its coefficient is added successively by a result counter 50. Also, the circuit 49 inputs a clock pulse CLK1 and 2 from a clock generator 48 and outputs the coefficient in a form of a pulse number. In the counter 50, a correlation value of once of a template and a sample is calculated, and whenever the correlation value is derived by shifting the template and the sample, its value is transferred to a result memory 51. Accordingly, a correlation characteristic curve is stored in the memory 51. Also, a main controlling circuit (15) which is not shown in the figure derives a position of an extreme value (maximum) in the correlation characteristic curve in the memory 51.

Title: Method for sterilizing tap water
Inventor: GOSHIMA NOBUTAKA
IPC: C02F1/46
Filed: 1992-09-17
Abstract: PURPOSE:To allow tap water which is constantly subjected to electrolytic treatment to flow through a tap and supply a limpid tap water from the tap by refraining from the consumption of tap water equivalent to a water flow from the inlet of an electrolytic tank to the tap, when the tap is opened for longer than a specified time after the closing of the tap. CONSTITUTION:If a tap 48 is opened when a tap water sterilization device is used, water passes through tap water piping 4 and a branched pipe 50 and becomes filtered by a main filter system 32. Then the water reaches a main electrolytic tank system 12, passing through a tap water sluice pipe 44 and a connection pipe 52. Further, the water flows out of a tap pipe 52 on the tap 48 side as electrolytically treated limpid tape water. Following this process, the tap water which is present in the tap water pipe from the inlet part of the main electrolytic tank system 12 at the tip of a tap water feeder pipe 35 to the tap 48 is refrained from being used with the sounding of a buzzer only for the period of time equal to the duration of water flow from the tap 48, if the tap 48 is reopened following the closing for a specified period of the tap 48 connected to the main electrolytic tank system 12. Yet, if the tap water which flows out after the suspension of its use is used again, a limpid tap water which is constantly sterilized can be used.

Title: Magnetic disk
Inventor: SATO HIROSHI
IPC: G11B5/82
Filed: 1988-10-28
Abstract: PURPOSE:To intensify the hardness of a magnetic film and to improve the durability of the magnetic disk by incorporating diamond powder into the magnetic film. CONSTITUTION:The magnetic film 10 is formed of magnetic powder 11, a binder resin 12, alumina powder 13, and diamond powder 14, as well as a layer of a lubricating agent 15 covering the surfaces thereof. Namely, the amt. of the alumina powder which can be incorporated into the magnetic layer has the threshold in terms of electromagnetic characteristics and, therefore, the diamond powder harder than the alumina powder is incorporated therein. A head comes against the projections of the diamond powder when the head comes into contact with the magnetic disk. Peeling of the magnetic film is thereby prevented. Since the hardness of the magnetic film is improved, the durability of the magnetic disk is improved without increasing the ration of the lubricating agent.
