Title: Doorway step
Inventor: NAKAGAWA HIROAKI
IPC: E04B1/00
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a doorway step having good work-excutable properties by forming the same from precast concrete. SOLUTION: A member open across its front and rear faces, the inside 11 of which is hollowed out, has a step 12 formed at the upper surface of one end to form a doorway step 10, which is made from precast concrete with an uneven surface. The doorway step 10 is installed on the indoor side of a doorway 22 and along the outer surface of a foundation 20, and an underfloor ventilating opening 23 is exposed to the outside via the inside 11 of the doorway step 10. Since the step is made from precast concrete, dry construction method is employed, eliminating the need for on-site curing, etc., and enabling construction period to be reduced.

Title: Switching circuit
Inventor: FUKUSONO HIDEKI
IPC: H03K17/13
Filed: 1980-01-31
Abstract: PURPOSE:To reduce the power loss and to increase the reliability, by taking the contact switching time until the common contact opens from a normally closed contact and contacts a normally open contact, a half cycle or more of AC power input applied to the control terminal of a switching circuit. CONSTITUTION:When a control signal Ec is applied to a relay RL, the common contact (c) is driven and it opens from a normally closed contact (a), and AC power input AC is applied to control terminals 1, 2 of a switching circuit ZS via a load L and a resistance R1, tri-terminal thyristor T is conductive near the zero cross point of the power input AC, and the load current flows through the thyristor T. When the contact (c) is in contact with the normally open contact (b) to short- circuit the both ends of the thyristor T, the load current flowing to the thyristor T flows through the contacts (c) and (b). In this case, the contact switching time until the contact (c) is disconnected from the contact (a) and is brought into contact with the contact (b), is taken as a half cycle or more of the power input AC  applied to the control terminal of the switching circuit, allowing to reduce the  power loss and to increase the reliability.

Title: Paper jam detecting mechanism
Inventor: TAKAHASHI TOSHIMI
IPC: B41J29/48
Filed: 1989-01-20
Abstract: PURPOSE:To allow a paper jam to be automatically detected, and printing and paper feed to be stopped by installing a sensor for detecting a rotary condition on a paper feed roller and a pressing roller which follows the transport of paper. CONSTITUTION:If a feed roller 2 rotates, a form 8 is fed and a processing roller 1 follows the feed roller 2 to rotate. If the feed of the form 8 is discontinued, while the feed roller 2 is rotating, a pressing roller 8 stops due to the discontinued feed of the form 8. If a rotation detecting sensor 4 detects the discontinued rotation of the pressing roller 1 while the feed roller 2 is rotating, a printer control circuit 5 stops printing and form feed immediately. The form is fed by engaging a pin tractor wheel 3 with perforations provided along both sides of the form 8 in addition to the feed of the form using the feed roller 2.

Title: Liquid crystal display unit of fluorescent type
Inventor: FUNADA FUMIAKI
IPC: G02F1/1335
Filed: 1978-02-03
Abstract: PURPOSE: To increase the intensity and display contrast, by effectively utilizing the fluorescent light away from the end of the display surface, in the liquid crystal display element which applies stimulate field by changing the intensity to the thin layer of the liquid crystal dissolving the organic fluorescent substance.  
     CONSTITUTION: At the end orthogonal or nearly orthogonal to the display surface of the substrates 1a and 1b, the reflection layer consisting of high refractance such as Al is attached or closely attached with evaporation. The fluorescent light from the organic fluorescent substance 6 enters the substrates 1a and 1b. Since the refractive index of the substrates 1a and 1b is greater than that of air, the fluorescent light repeats full reflection at the boundary between the substrates 1a and 1b and air and propagates. The fluorescent light reached the end is reflected with the reflection layer 9 and it is again returned to the substrates 1a and 1b and in the liquid crystal layer 8. Thus, when the center of scattering of fluorescence is formed in the crystal layer 8 with the stimulated field, the fluorescent light emitted on the display surface is increased depending on the amount of reflection at the end of the substrates 1a and 1b.

Title: Dynamic focus system ultrasonic diagnostic device
Inventor: OKUDA DAIJI
IPC: A61B8/14
Filed: 1989-01-21
Abstract: PURPOSE:To improve a frame rate and to improve resolution using a delay line having fixed delay quantity without increasing cost by equipping the subject ultrasonic diagnostic device with a reception signal image data storing means, a data write-in control means, a switching timing control means, etc. CONSTITUTION:For a scanning beam 1, in a first transmission, while image data are written an image memory 10 at a depth position indicated with a continuous line, the image is never written in the memory 10, and null is obtained in the periods of noise generating periods (tap switching periods) P1, P2, and P3. However, in a second transmission, the image data are written in the image memory 10 at another depth position indicated with a broken line. Consequently, the P1, P2, and P3 parts in the first transmission can be compensated with the broken line (the second transmission), and an omitted part in the second transmission can be compensated with the continuously line (the first transmission). Consequently, image quality can be improve. Further, it becomes unnecessary to provide plural delay circuit systems for each piezoelectric transducer, composition of the device can be simplified, and the cost of the device can be made low in cost.

Title: Attitude control device for vehicle
Inventor: IZUMI TOMOMI
IPC: B60T8/58
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from drifting out by sufficiently reducing the speed of the vehicle without harming stability of the attitude of the vehicle. SOLUTION: The attitude of a vehicle is controlled by giving (SC6 and SC7) braking force to the front wheel or rear wheel inside the turning circle when yaw rate deviation (y) that is the deviation of the yaw rate of a vehicle from the target rate becomes equal to or larger than the judging yaw rate deviation, and then speed reduction is conducted by giving (SC12) braking force to the front wheel outside of the turning circle of the vehicle and the rear wheel inside the turning circle. When it is judged (SC8) that there are no changes in the attitude inside the turning circle of the vehicle, the current control immediately shifts (SC12) to speed reduction control. On the other hand, when it was judged (SC8) that there are changes in the attitude, the speed reduction control of the vehicle is executed (SC12) after the vehicle was sufficiently oriented to the inside of the turning circle of the vehicle and the amount Δx of change of the deviation (x) of the angle of the side-slip of the vehicle becomes more than the amount Δx 1 of first judgment (SC10).

Title: Mechanical control method and device
Inventor: GUSUTAFU TENESU
IPC: B23K7/00
Filed: 1986-01-24
Abstract: A method and apparatus for mechanically controlling the flame cutting and/or connection welding of workpieces. The difficulty encountered during the mechanized burning of holes in vessels, containers or tanks and the welding of connecting members into these holes is that the cutting and welding apparatus need to be guided in such a way that not only do they not contact the surface of the vessel, container or tank, but they are also kept a fixed distance from this surface. Therefore, control of the cutting and/or welding process is effected in conformity with the actual dimensions of the workpiece that is being worked on. In particular, this control is undertaken in conformity with the circumferential line of the hole for a given connecting member, and also in conformity with the curved surface of the vessel, container or tank. The peripheral line of the connecting member is first sensed and is graphically or electromagnetically recorded. The subsequent control of the cutting and/or welding process is then effected by following this recorded line.
