Patent JP-H07172420-A (JP)
Title: Counter for packed coins
Inventor: WATANABE KENJI
IPC: B65B35/50
Filed: 1993-12-21
Abstract: PURPOSE:To correctly count a number of packed coins without being influenced by difference in thickness of coins. CONSTITUTION:A light projection/reception unit 25 has a light source 23 and a light receiving element 24 opposite at a distance for allowing packed coins 22 to pass through in a plane perpendicular to a center axis line of the coins 22. A moving means 30 allows the packed coins 22 to pass through the light projection/reception unit 25 at a relatively constant speed. A peak detection means 36 obtains all peaks with respect to a change in a light amount received by the light receiving element 24 when the packed coins 22 relatively passes through the unit 25. A unit distance setting means sets the minimum distance between the peaks obtained by the peak detection means or a distance corresponding to one coin per coin type as a unit distance. A number calculating means obtains how many times the unit interval the interval between the respective peaks is to calculate a total of the obtained values. Therefore thickness of each coin is detected in a narrow range with little error.

Title: Method for controlling flow of gas in rotary hearth type heating furnace
Inventor: KUBO KISHIO
IPC: C21D1/00
Filed: 1987-12-18
Abstract: PURPOSE:To improve thermal efficiency for heating and to improve the fuel consumption unit of a rotary hearth type heating furnace having burners by decreasing the flame releasing gas and short-circuiting gas in a combustion gas and decreasing the quantity of infiltration air at the time of heating billets for hot pipe making in the above-mentioned heating furnace. CONSTITUTION:The correlative relation between the supply rate of the fuel and the pressure in the inlet of a flue where the flow of the gas in the furnace is optimum is previously determined at the time of heating the billets with the doughnut-shaped heating furnace 1 which is provided adjacently with a billet charging port 2 and ejecting port 3, has 6 pieces ot zones 4-9 as the rotary hearth, has the plural burners on the inside and outside walls of the respective zones and is provided with a down take 10 connected to the flue between the charging port 2 and a 1st zone 4. The effective gas A to be effectively utilized for heating the billets is increased by correcting the concn. of the O2 in the flue in such a manner that the exhaust gas in the inlet of the flue attains an optimum pressure at the time of an actual operation, by which the effective flame releasing gas B ejected from the charging port 2 and the ejecting port 3 and the short-circuiting gas C escaping directly to the flue from the final zone 4 are decreased. The infiltration air from the charging port and the ejecting port is thereby decreased and the thermal efficiency of the furnace is improved.

Title: Servo motor control system
Inventor: MATSUBARA SHUNSUKE
IPC: G05D3/12
Filed: 1991-11-12
Abstract: PURPOSE:To obtain a servo motor control system quickening the convergence of a position deviation and a speed deviation, being excellent in a responsiveness and also strong against an external diffusion and not generating a mechanical resonance. CONSTITUTION:When a torque command Tc1 obtained from a conventional speed control is small, a gain for adjustment G is increased and when the torque command is large, the gain for adjustment G is decreased (S1 to S3). A torque command Tc2 to be obtained by multiplying the gain C for this adjustment G by the Tc1 to be the output of a speed control part is defined as a torque command to the servo motor (S4, S5). As the gain becomes higher when a position deviation and a speed deviation are small and the torque command Tc1 is small, a response becomes excellent and a convergenence is quickened. When the torque command Tc1 is large, the gain is low and a mechanical resonance is not generated.

Therefore, the leakage current tests of both the P-type channel transistor 11 and the N-type channel transistor 21 can be performed formed simultaneously. With this constitution, the test can be simplified.

Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To provide an oblique elevator car device which can provide required braking force when the car is lowered at a excessive speed and gives less horizontal braking force to passengers. SOLUTION: A car 2 is guided to an inclined rail 1, and an emergency stop device 6, which ascends and descends together with the car 2, is provided on the lower side. The car 2 is provided with a braking mechanism 21 with a function 20 to move upward and downward. In the car 2, a connection means 16 is provided to connect the car 2 and the emergency stop device 6 forming space, and a damper 22 is secured in either of the two mentioned above and opposed to the other.

The release of the gas is prevented if the thin film of the zirconium carbide is interposed as the buffer layer 6. The lightlight and inexpensive magnetic recording medium obtd. while the good magnetic characteristics are maintained.

IPC: G02B6/42
Filed: 1987-12-21
Abstract: PURPOSE:To facilitate the alignment of a fiber sleeve by providing the reflecting surface being orthogonal to an optical axis on a part of the end face of the fiber sleeve and working only the periphery of the end face of an optical fiber so as to become oblique against the optical axis. CONSTITUTION:A fiber sleeve 10 with the reflecting surface having the reflecting surface 16 being orthogonal to an optical axis on the end face is placed so that a radiation light 7 of a laser diode LD is made incident on its reflecting surface 16. In this state, when the fiber sleeve 10 with the reflecting surface is moved in the optical axis direction, when a condensing point of the radiation light 7 of the LD has come onto the reflecting surface 16, an LD current 15 becomes minimum. Accordingly, by only monitoring the LD current 15, the condensing point of the radiation light 7 of the LD can be allowed to coincide with the end face of the fiber sleeve 10 with the reflecting surface. In such a way, by utilizing a return light to the LD of the LD radiation light 7, an optimum position in the optical axis direction of the fiber sleeve 10 can easily be detected.

Title: Multiple electron beam source and its driving method, and image forming device using the same
Inventor: TODOKORO YASUYUKI
IPC: H01J1/30
Filed: 1993-12-22
Abstract: PURPOSE:To correct variance in luminance among respective surface conduction type emission(SCE) elements arranged on an image formation panel. CONSTITUTION:An element current of each SCE element on the image formation panel when a signal having a certain value is inputted is monitored at a correction data generation part 113 by a current monitor 110. When the value does not match the stored element current data, the monitored element current is so connected as to match the stored current data. A proper value is written in a correction table in an LUT 106 for correcting the input signal so that the monitored element current is corrected so as to match the stored current data. Then, the element current of the element which is driven with the corrected signal is measured again and compared with the current data again. This processing is repeated until the monitored element current nearly matches the stored element current data. Thus, this processing is carried out as to all the elements to correct the variance. In this case, the luminance may be monitored by an luminance measuring instrument 115 or the discharge current from the SCE element may be monitored by a current monitor 118 instead of the element current.
