Title: Inspecting device for precipitated foreign object in bottle
Inventor: ONISHI TAKASHI
IPC: B08B9/46
Filed: 1991-09-24
Abstract: PURPOSE:To easily detect a precipitated foreign object at the bottom section having a small light reflectivity and liable to be overlooked with a high detection rate. CONSTITUTION:Laser beams 5, 5' from laser light source bodies 3, 3' are spread into a sheet shape and radiated in parallel with the bottom section of a bottle 1 above the bottom section of the bottle 1, only the liquid portion in the bottle 1 where the laser beams 5, 5' pass is made bright by scattering, and the light is captured as the background light A of an opaque precipitated foreign object 2 via a CCD camera 8 located directly below the bottle 1, an image processor 9, and a monitor device 10. Even if the laser beams 5, 5' do not pass the portion causing the image noise, they become the background light A of the opaque precipitated foreign object 2 having uniform brightness, an inspecting device of the precipitated foreign object in the bottle 1 captures the reflected light from the opaque precipitated foreign object 2 as an image signal having higher intensity than that of the background light A and captures the unreflected foreign object 2 as a picture element having small intensity, thus the precipitated foreign object 2 at the bottom section having a small light reflectivity and liable to be overlooked is easily detected with a high detection ratio.

Title: Draining packing for box for outdoor use
Inventor: NAKAMOTO ATSUSHI
IPC: H02B1/28
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To increase elastic force, and to make entry of rain water difficult by forming, in sealing strip, a partition which divides a cavity at a position different from a front strip. SOLUTION: If rainwater penetrates from a gap between a lid 2 and a box 1 with the lid 2 closed, a sealing strip 10 adheres closely to the rear of the lid 2 and curves in an outward direction, and causes the rain water to bounce at the tip of the sealing strip 10 and makes its entry into the box 1 difficult. The sealing strip 10 forms a partition 12 which divides a cavity at a position making it different from a front strip 4d, and prevents the cavity parts of the sealing strip 10 from becoming recessed. Consequently, increase in the elastic force of the sealing strip becomes possible, and penetration of rainwater is made difficult.

Title: Water condensate treatment device for air conditioner
Inventor: MATSUBAYASHI HIDE
IPC: F24F13/22
Filed: 1985-11-01
Abstract: PURPOSE:To make it possible for sure to splash the water condensate even under a high wind pressure by providing a water conduit which has its outlet section in a liquid tank at the lower section of a slinger ring and providing a flange round the outer circumference of the liquid tank. CONSTITUTION:The water condensate that is obtained from an indoor side heat exchanger flows in a water conduit 4, and it is supplied to a water tank 6 through a net 20 or many minute holes 21. The net 20 keeps dusts of relatively large diameters from entering the inside of the water conduit 4, and, further, even when the meshes of the net 20 are clogged, the water condensate is supplied to the water tank 6 through the minute holes 21 formed in the surface of the water conduit 4. When the water level in the water tank 6 becomes high, the water condensate is stirred by a slinger ring 5. During this stirring water drops attached to the end faces of the slinger ring 5 fly in water splashes through the space between the outdoor side heat exchanger 1 and a heat radiation cover 3, and part of the splashes evaporate to absorb the latent heat, thus heightening the capabilities of the heat exchanger to transfer heat. Furthermore, on the bottom face 10 of the liquid tank, many pleats 13 are formed to increase the frictional force between the water condensate and the bottom face 10 for reducing the amount of over-flow.

Title: Device for levelling high lift working vehicle
Inventor: FUJIOKA MASARU
IPC: B66F11/04
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a device for levelling a high lift working vehicle, capable of eliminating the delay of the levelling of a working floor from the hoisting of a boom at starting the hoisting of the boom and holding the working floor in a balanced condition in the case of part of hydraulic fluid supply passage to a levelling cylinder being broken. SOLUTION: When the hoisting of a boom 14 is started in the condition that the boom 14 is not hoisted (the operation of a levelling cylinder 23 is stopped), an additional flow for restricting the delay of the operation of the levelling cylinder 23 from the hoisting of the boom 14 at starting the hoisting of the boom 14 is added to the levelling flow of hydraulic fluid required to support a working floor in a balanced condition. The hydraulic fluid of a corrected hydraulic fluid flow (a levelling flow plus an additional flow) obtained in this way is supplied to the levelling cylinder 23 by driving a balance control valve 55.

Title: Non-volatile semiconductor memory device
Inventor: MOMOTOMI MASAKI
IPC: G11C16/06
Filed: 1987-09-30
Abstract: PURPOSE:To suppress the deterioration with the lapse of time of a tunnel insulating film by providing a limiter circuit for generating a potential boosting stepwise and connected to a boosting circuit. CONSTITUTION:A high voltage Vpp for a program generated by the boosting circuit 11 is supplied to a memory cell array 13 through a decoder circuit 12. The limiter circuit 14 for boosting the potential for the program stepwise is disposed between the boosting circuit 11 and the decoder circuit 12. Namely, since the boosting potential for the program is boosted stepwise by the limiter circuit 14, the output waveform of the boosting circuit 11 is gradually led while rounding the output wave shape. Accordingly, a floating gate injects and discharges an electron simultaneously with the boosting of the voltage and a high electric field is not impressed to the thinned tunnel insulating film layer. Thereby, the deterioration with the lapse of time of the tunnel insulating film layer can be suppressed to enhance the reliability.

This signal (c) is added to the signal (b) in an adding circuit 13, and as a result, one cycle is divided into four sections and to the respective sections three levels are assigned to have an output signal (d).

Abstract: PURPOSE:To attain the crosstalk characteristics adequate for practicable use with a low driving voltage and the range of wide driving voltages by increasing the opening angle of two waveguides on the side of the beginning ends of the curved parts respectively provided in the two waveguides and decreasing this opening angle on the side at the terminals of the curved parts. CONSTITUTION:The opening angle of the two waveguides 12, 14 on the side of the beginning ends of the curved parts II respectively provided in the two waveguides 12, 14 is increased and the opening angle is decreased on the side at the terminals of the curved parts II. The values of the index gamma of mode conversion distribute like a mountain according to numerical analyses. The position of the max. value of the index gamma shifts from the side at the terminal of the two waveguides to the side of the branch part and the max. value of the index gamma decreases with an increase in the driving voltage. The waveguide type optical switch lends itself to practicability if the crosstalk characteristics thereof attains a specified level, for example, -15 to 20dB. Thus, the crosstalk characteristic suitable for practicable use is obtd. with the lower driving voltage than heretofore in the range of the wider driving voltages.
