Title: Injection molding machine utilizing closed tank
Inventor: MAKI HIROSHI
IPC: B22D17/32
Filed: 1994-07-11
Abstract: PURPOSE:To prevent contamination of operation oil by connecting a closed tank in which the operation oil for an actuator is stored to an air reservoir with mutual gas exchange being freely performed, and thereby forming a closed system. CONSTITUTION:When operation oil in a closed storing tank 41 is fed into a closing ram of a closing device 44, a storing rate is decreased. Then, air by a decreased rate is moved from an air reservoir 42 to the tank 41, and a bladder 42b is contracted. On the contrary, when the closing ram retreats and the operation oil is fed back into the tank 41, the storing rate is increased, air in the tank 41 is moved to the air reservoir 42, and the bladder 42b is expanded. Air exchange is enabled only between the tank 41 and the air reservoir 42. A hydraulic system is perfectly interrupted from atmosphere. It is necessary at this time to enlarge capacity of the bladder 42b compared to the maximum fluctuation rate of the operation oil in the tank 41. The operation oil is perfectly prevented from being contact with atmosphere, and entrance of foreign materials is prevented in respect to the operation oil. In addition, injection of oil mist to outside is also prevented.

Filed: 1983-09-30
Abstract: PURPOSE:To measure the dispersing characteristic of an optical fiber with high accuracy, by performing sine wave modulation to continuously oscillating laser diode beam and measuring the change in the phase characteristic of the optical fiber to the change in modulation frequency while calculating the wavelength dependence of group delay time characteristic. CONSTITUTION:Measurement is performed while measuring beams from laser diodes LD1-LDN different in a light emitting wavelength are successively changed over to a fiber 2 to be measured by a change-over means 1. At first, sine wave modulation is applied to the diode LD1 by an oscillator 3 and propagated through the fiber 2. The output beam from the fiber 2 is sent to a phase difference detector 5 through APD4 to measure the change DELTAbeta(f) in the phase characteristic of the fiber 2 to the change DELTAf in modulation frequency. Subsequently, a group delay time characteristic tau(lambda) to the wavelength lambda of laser diode beam is calculated. This calculation is performed with respect to LD2- LDN and wavelength dependence of the time characteristic tau(lambda) is calculated to make it possible to measure the dispersing characteristic of the optical fiber 2 with high accuracy.

Title: Rotary type compressor
Inventor: KUBO MASAHIRO
IPC: F04C23/02
Filed: 1985-08-20
Abstract: PURPOSE:To raise rigidity of a rotary shaft, increase the durability of a sliding bearing greatly and enhance the rotational efficiency by forming the rotary shaft from a material having a Young's modulus no less than a certain specific value. CONSTITUTION:When slide bearings 7a, 7b are set in a rotary compressor 2, the rotary shaft 4 swings within the bearings, which should originate from flexibility of the rotary shaft 4 or its supporting system. As the factors for flexibility of the total system are considered the rigidity of the rotary shaft 4, rigidities of bearing 7a, 7b housing (bearing and its supporting system), and rotary supporting rigidity of the bearing housing. A conventional arrangement can provide the required rigidity of bearing housing as well as rotary supporting rigidity, but demonstrates a considerably lack of the rigidity of rotary shaft 4. Thus the rotary shaft 4 is formed from a material having a Young's modulus over 150GPa, for ex. spherical graphite cast iron (FCD) which has a Young's modulus of 165GPa. This will increase the rigidity of shaft 4 to lead to enhancement of the durability of bearings and the rotational efficiency to a great extent.

Abstract: PURPOSE:To prevent insertion ratio from being reduced due to calibration failure of a printed circuit board in advance by comparing the area of a reference pin which is measured by the recognized reference pin with that of the reference pin which is set in advance and then giving a warning when the value is lower than a reference area. CONSTITUTION:A reference pin recognition camera 13 is installed within a range where a reference pin 10 can be recognized and the area of the reference pin 10 is calculated based on the reference pin recognition image of the camera 13 by an image processing part 15. When the value is lower than a reference value, the reference pin 10 is replaced or a warning which is set again is given. Also, when the position of the reference pin 10 deviates, a compensation value is calculated for NC data 16, thus compensating the position of an X-Y table 3. Therefore, the setting mistake of the reference pin caused by the change in printed circuit board calibration mechanism or the replacement of the reference pin can be compensated, thus obtaining a more reliable packaging machine.

Title: Image forming device
Inventor: OGAWA KIYONARI
IPC: G03G9/08
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To easily obtain a high-quality output image by constituting a device so that the toner shape coefficient of one-component developer at a transfer time becomes smaller than that in a developing means. SOLUTION: This device is constituted so that the toner shape coefficient SF1 of the one-component developer at the transfer time becomes smaller than that in the developing means. Therefore, since the shape of toner used in the developing means is aspherical, the friction and rubbing of the toner can be facilitated differently from a case that spherical toner is used. Besides, a toner thin layer is easily formed on the surface of a developing blade and triboelectrification imparting property with respect to the toner is enhanced. By making the coefficient SF1 small and making the shape of the toner used for transfer spherical at the transfer time, transfer efficiency is enhanced and the middle omission of the transfer is prevented from occurring.

Filed: 1983-09-30
Abstract: PURPOSE:To improve reliability by arranging a concave mirror split into n-division in the scanning direction of a laser beam at two upper/lower stages while shifting a phase so as to allow each division to cover mutually a boundary part thereby detecting surely a reflected light from the concave mirror. CONSTITUTION:The phase of the n-division concave mirrors 18A1-18A5 and 15B1-15B5 constituting two upper/lower stages is fixed while it is shifted by a half of the width. In applying simultaneously a laser beam scanning to the concave mirrors of the two upper/lower stages, each reflected light is detected by photodetectors 17A1-17A5 and 17B1-17B5 and after the light is amplified by an amplifier 13, the result is given to an adder 20. Since the reflected light of the laser beam scanning the concave mirrors 18A, 18B of the two upper/lower stages generates the output signal of in-phase from the photodetectors arranged upper and lower in terms of timing, the output signals is specified to be an input signal to the adder 20 by ORing both. A timing clock signal output is obtained from the adder 20.
