Title: Second harmonic generating device
Inventor: SAKURAI HIROMI
IPC: H01S3/109
Filed: 1990-08-16
Abstract: PURPOSE:To simplify adjustment of the rotation angle for a phase compensator device, improve stability, and achieve greater efficiency by adjusting the phase shift within + or -pi/2 by means of a non-linear optical element. CONSTITUTION:Light emitted by a laser medium 5 is phase shifted delta by a non-linear optical crystal 1 and is directed to a phase compensator device (lambda/4 board) with a rotation angle of theta. The polarization state of light emitted by the laser medium 5, reflected by an output mirror 7, and returning to the edge of the laser medium 5 is expressed by a Jones matrix M. When the electric vectors E1 and E2 that cross perpendicular to the proper polarization vector of the fundamental wave laser light within the resonator and the average power value I (2omega) of the second-harmonic laser light are determined by the matrix M, the term expressing the case when two modes are mutually coupled is included. While he permissible angle theta of the stable area when delta=0 deg. is extremely narrow, the stable area is substantially increased when delta is about 90 deg.. Therefore, when delta is adjusted within the + or -90 deg. range, stable output and high efficiency can be effectively achieved for the second-harmonic generating device.

IPC: G06F3/033
Filed: 1992-07-21
Abstract: PURPOSE: To enable an accurate one hand operation by integrating motion encoding and a generation means of selection signals not to have to operate the push buttons or other selection devices which are separated. CONSTITUTION: On a selection device B, a track ball is mounted on rolls 12 and 14 in a free rotatory state. The rolls 12 and 14 are connected to rotation encoders 16 and 18 respectively which generate pulse trains. Up/down counters 20 and 22 change the pulse into a linear motion instruction that goes along a bi-axis. A converter 50 outputs electric signals regarded as selection signals when the track ball is affected by downward non-rotation pressure. The converter 50 is the one whose strain gauge or output amount changes itself according to the strength of force. A comparison device 54 instructs whether to generate a selection signal by comparing the output of the converter 50 with a selectable threshold.  A converter in another execution example has a binarization state, e.g. it changes states when it exceeds the prescribed minimum value by responding to affecting force to the track ball, 10 by means of a mechanical switch.

Title: Shape controller for cluster mill
Inventor: KAJIWARA TETSUO
IPC: B21B13/14
Filed: 1990-08-17
Abstract: PURPOSE:To prevent wear and scratch due to slip between rolls from occurring and to improve the capacity for controlling the shape of strip by adjusting the position of the axial centers of back-up rolls which are situated at the shaft ends of the shaft of the back-up rolls in accordance with signals from both detectors for roll bending force and rolling load. CONSTITUTION:When bending stress is applied to an intermediate roll 3, the bend of the intermediate roll 3 isn't entirely impeded, because the divided back-up rolls 4a, 4e at both ends are moved together with the intermediate roll by the freely bended quantity of the intermediate roll 3 while they are brought into contact with the intermediate roll 3. In other words, deflection compensation by the bending of the intermediate roll 3 is equal to that in the case the divided rolls 4a, 4e at both ends are completely relieved and not brought into contact. Therefore, not only wear and scratch due to slip between the back-up rolls 4a-4e and the intermediate roll 3 are not generated, but the maximum compensation effect of the deflection of roll due to bending of the intermediate roll can be utilized from a wide sheet to a narrow sheet.

IPC: B65H3/06
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To enhance the productivity of image formation and reduce the manufacturing cost by reducing intervals of sheets which are successively fed into an image forming part. SOLUTION: A sheet 3 conveyed from a conveying path 18 and accommodated in a switch back path 17, is switched back by conveyer rollers 21, 22 so as to be fed on a conveying path 19 toward an image forming part 2. The conveyer roller 21 also serves as a conventional register roller. That is, when a predetermined period elapses after the sheet 3 which has been fed out from the switch back path 17 by means of the conveyer roller 22 is detected at its leading end by a register sensor 24 at a position just upstream of the conveyer roller 21 in the conveyer path 19, the conveyance by the conveyer roller 22 is stopped. Thus, the sheet 3 is made to abut against the conveyer roller 21 so as to effect registration.

Title: Solar energy utilizing plant
Inventor: TANI TATSUO
IPC: F24S90/00
Filed: 1982-12-10
Abstract: PURPOSE:To lower the pressure resistance and to improve the heat exchanging efficiency of titled device with working medium, by heating a heat medium which has been heated through a solar energy collector to cause the same to enter into direct contact with the working medium of low boiling point to evaporate the latter for its return to the collector after decompression. CONSTITUTION:A heat medium a is heated up in a solar energy collector 1 and then fed to a direct contact type steam generator 2'. In the direct type steam generator 2', the heat medium a is caused to enter into direct contact with a working medium b having a boiling point lower than that of former to heat up and evaporate the former. The steam of this working medium b is supplied to an utility such as a turbine and the like by means of a pump 7. In this case, because the direct contact type steam generator 2' has an internal pressure equivalent to the evaporating pressure of working medium b, the pressure of heat medium a is lowered 8 through a return pipe while being increased by means of a pump 3. In this arrangement, the pressure resistance of titled device can be lowered, and thereby improving its heat exchanging efficiency with the working medium.

Abstract: PURPOSE:To effectively prevent damage of a vehicle and damage of a motor caused by a lock plate by driving the motor and allowing the lock plate to ascend, after a prescribed elapses after a display means for displaying a charged state is driven after a service time elapses. CONSTITUTION:When a vehicle is detected by a sensor S1, a service time is measured. After the service time elapses, a display driver is driven and a parking charge is displayed on a charge display part 4, and also, counting of the parking charge is started. However, at this time point, a lock plate 1 does not ascend yet. Accordingly, just before the service time expires, even if a user gives up parking and tries to withdraw therefrom, the vehicle can withdraw freely. when a prescribed time elapses after the parking charge is displayed, that is, after the service time elapses, a motor driver is driven and the lock plate 1 ascends, and thereafter, withdrawal of the vehicle is obstructed. Also, a fact that the withdrawal is impossible is informed to the user by turning on a withdrawal impossible lamp.
