IPC: B21D1/05
Filed: 1980-04-16
Abstract: PURPOSE: To utilize the crown effect of roll for uniformalizing the lateral elongation of strip, and to correct the shape of strip into good conditions, by gradually changing the outer diameter of roll on the run-out side of each of tension roll group and camber correcting roll group, from the end to the middle of roll drum.  
     CONSTITUTION: In the tension roll group 14, 15 and the following camber correcting roll group 16, 17 both being arranged between the feed-in side and the run-out side anticrimping rolls 12 and 13, both of the run-out side roll 15 of the tension roll group and the run-out side roll 17 of the camber correcting roll group are made as a convex crown roll wherein the effective outer diameter of roll is gradually changed as compared with the outer diameter of roll end. Hereby, in case of handling an annealed material, the crown effect of roll 15 is canceled by the following roll 16, and the effect of crown shape of the roll 17 further shortens pathway of the side edge of strip 11, so that the lateral elongation of strip becomes uniform and the shape of strip is improved. In case of a full-hard material, the crown effect of roll 15 corrects the shape of strip 11 similarly to above.

Abstract: PURPOSE:To facilitate carry-in and carry-out of a vehicle by locating the body section below the floor surface and disposing a section for delivering the cooling air to the vehicle retractively on the floor surface. CONSTITUTION:The body section 5c including the sucking section 5b of a cooling fan 5 is disposed in a pit 6 under a floor surface 2 and the delivery section 5a is inserted into the body section 5c movably up and down. The delivery section 5a is located slightly below the floor surface 2 when the cooling fan 5 is not operating but when the cooling fan 5 is operated, a hydraulic cylinder drives a drive lever upward to move the delivery section 5a upward thus locating a delivery port 5e above the floor surface 2. A motor in the body section 5c is then driven to suck the cooling air through the sucking section 5b and the cooling air is blown toward a vehicle on a roller through the body section 5c, the delivery section 5a and the delivery port 5e. When the fan 5 is not operating, the hydraulic cylinder is driven to lower the delivery section 5a below the floor surface 2. This structure causes no hindrance to carry-in and carry-out of the vehicle.

Title: Optical parametric resonator
Inventor: TSUNEKANE MASAKI
IPC: G02F1/39
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To excite a non-linear optical crystal without passing it through a mirror for resonance by providing a resonator with a dichroic mirror arranged on the optical path of an optical parametric light beam and set for guiding excitation light made incident from the outside of the optical path and making it incident on the non-linear optical crystal. SOLUTION: This optical parametric resonator 10 is constituted of two multilayered film mirrors 12 and 13, the BBO crystal 14 being the non-liner optical crystal and the dichroic mirror 11 having high transmissivity extending over the wavelength of 700nm from the wavelength of 400nm and high reflectivity near the wavelength of 266nm. Then, a laser beam 15 whose wavelength is 266nm is reflected by the mirror 11 so as to excite the crystal 14. By the excited crystal 14, the optical parametric light beam 16 extending over the wavelength of 700nm from the wavelength of 400nm is emitted. The beam 16 is transmitted through the mirror 11 and shut in by being repeatedly reflected by the mirrors 12 and 13. Thus, optical parametric oscillation is generated.

Title: Ignition control device
Inventor: AKAGI MOTONAGA
IPC: F02P15/10
Filed: 1990-03-01
Abstract: PURPOSE:To enhance the ignition efficiency by generating a signal with which a gradient signal generating means begins rising linearly from the base point of the primary coil current peak value during the sampling period, and shutting the current feed to a primary coil when it attains the set level. CONSTITUTION:When current feed to the primary coil of an ignition coil IG1 is started, the current feed begins with the level corresponding to the residual current from the previous discharging, and within a certain period of time Tc (sampling period) therefrom the pulsation peak value of the current flowing in the primary coil (charging current) is being held, and an electric signal rising linearly from the base point of peak value generated by a gradient signal generating means 40 is free of pulsation. This shifted to the High side if it is high with respect to the residual current of the previous discharging, and is shifted to the Low side. Because the peak value is proportional to the residual current, the time from a switching means 91 being turned on till being shut becomes a value proportional to the residual current, to be stabilized into a substantially constant period of cycles in compliance with the set level of the abovementioned electric signal and the set time for shutting.

Title: Controller for vvvf inverter
IPC: H02P27/06
Filed: 1992-03-09
Abstract: PURPOSE:To prevent an overexcitation at the time of readherence after slips of wheels by correcting a voltage command value in a direction for lowering it when the slips of the wheels are sensed during driving of a motor with a VVVF (variable voltage variable frequency) generated by converting an input DC voltage as a voltage command value. CONSTITUTION:A voltage command operator 15 calculates and outputs a voltage command value VD based on a modulation factor obtained from a DC input voltage and an output frequency of an inverter. On the other hand, when a slip is sensed from a rotating frequency of a motor, a slip flag outputs '1' to switch switching units 17, 18 to '1' side. The unit 17 outputs a coefficient smaller than '1' such as '0.95', multiplies it by the value VD by a multiplier 20 to correct the command value to a smaller value, and outputs it from the unit 18 as a voltage command. When the output of the flag becomes '0', the units 17, 18 are switched to '0' side, the value VD is multiplied by the coefficient '1' by the multiplier 20, gradually returned to an original value through a temporary delay element 19, and output from the unit 18. Thus, an overexcitation at the time of readherence is prevented.

Abstract: PURPOSE: To save the absorbing member behind the reflecting mirror, ease manufacture and perform the wavelength selection of reflected light effectively by using the absorbing member of light to the reflecting mirror within the lens holder provided to the exposure optical path of a copying machine or the like.  
     CONSTITUTION: A reflecting flat plate 3 in a lens holder 1 is composed of a member which absorbs light, e.g., ceramic aluminum close to black color. The surface of the incident side of light is a mirror surface and a reflecting layer 4 composed of the materials which reflect light of the required wavelength region, e.g., alternate layers of CeO 2  and MgF 2 , are evaporated on said mirror surface. When the light l emitted from the original transmits through a converging lens 2 and reaches the reflecting flat plate 3, only the light of the required wavelength region corresponding to the spectral sensitivity characteristic of the photosensitive object is selectively reflected by its reflecting film layer 4, whereby the photosensitive object is exposed. On the other hand, the light of the unnecessary wavelength region is completely absorbed in the flat plate 3.
