Title: Frost-damage preventor pile
Inventor: TAKEDA TAKASHI
IPC: E02D5/60
Filed: 1985-05-14
Abstract: PURPOSE:To keep structures from frost damage in cold areas by reducing frost- heaving forces acting on piles by forming a low-friction plastic layer through an adhesive plastic layer on the outer surface of a pile. CONSTITUTION:An adhesive plastic layer 11 is formed over a length more than the thickness of a surface active layer 6 on a pile 10, and a low-friction plastic layer 12 is further formed on the layer 11. For the layer 12, the fine powder of trifluoroethylene or tetrafluoroethylene is added to the material of the layer 12. The surface active layer 6 and a permanent frozen ground layer 5 are excavated by the burying depth h+H of the pile 10, the pile 10 is penetrated into the pit 7, and the surrounding of the pile 10 is embedded back with sand slurry 8. Frost heaving forces acting on the pile 10 can be reduced by the layer 12, and therefore structures in cold areas can be protected from frost damage.

Title: Pachinko machine
Inventor: WATANABE KANEHISA
IPC: A63F7/02
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a PACHINKO machine which has fresh and highly enjoyable game contents and which enables a player to play with unchanged interest. SOLUTION: A PACHINKO machine 1 is constituted such that, when a ball wins an ordinary motor-driven premium 4, three special picture patterns displayed in a special picture pattern display 3 start varying, and when a combination of the special picture patterns displayed after the variation is a 'big-hit picture pattern', a 'big-hit state' advantageous to a player is brought about. Also, as the 'big-hit picture pattern' a 'special picture pattern' and a 'non- special picture pattern' are set beforehand, and when the displayed 'big-hit picture pattern' is a 'special picture pattern', a 'high probability state' advantageous to the player is brought about after the 'big-hit state' terminates.  Further, even when the 'non-special picture pattern' is once stopped to display after the variation of the special picture pattern, each special picture pattern revaries to enable the 'special picture pattern' to be displayed.

Title: Abnormality alarm device
Inventor: KATSURAGI YOSHIO
IPC: G08B23/00
Filed: 1988-04-22
Abstract: PURPOSE:To obtain a compact abnormality alarm device that can produce alarms for various abnormal states and to realize the cost reduction of an alarm system by providing plural detecting means which detect different abnormal states, a single diode, a control means, and an operating switch. CONSTITUTION:In case the liquid level drops in an abnormal state, for example, a contact 1a1 is closed and a half-wave alternate current flows to a lamp 5 and a relay coil 2c from an AC power supply bus 9 via the contact 1a1 and a diode 6. Thus the lamp 5 is turned on to alarm the abnormality. In this case, a relay 2 is used for AC and does not work due to the insufficient excitation. When the liquid level drops less in a dangerous state, the contact 1a2 is closed and the coil 2c is energized with contacts 2a1 and 2a2 closed. Thus a lamp 4 is turned on to warn a dangerous state. When the contact 2a1 is closed, a current flows to a series circuit of a self-support release switch 7 and the contact 2a1 and the coil 2c is self-supported. Thus the warning actions last even though both contacts 1a1 and 1a2 are closed and then opened.

Title: Electronic camera, finger-put detecting method therefor and level converting method therefor
Inventor: YAMAZAKI AKIHISA
IPC: G03B15/05
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To give the caution for the finger-put state of a stroboscope to a user without providing a dedicated sensor for detecting finger-put. SOLUTION: A signal level detection block 36 detects whether exposure is under or not based on image data fetched at a stroboscopic photographing time. A stroboscope flash quantity detecting circuit 44 detects whether the flash quantity at the stroboscopic photographing time is the maximum or not. A CPU 46 judges that the finger-put state of the stroboscope is caused when the under exposure is detected and the flash quantity of the stroboscope is not the maximum, then the occurrence of the finger-put state is displayed at an alarm display part 48.

Title: Semiconductor device
Inventor: IMAI HITOSHI
IPC: H01L21/318
Filed: 1987-04-22
Abstract: PURPOSE:To prevent a diffusion into a substrate of an impurity in a film by a nitride film on annealing, and to lower wiring resistance by depositing the nitride film under the film consisting of BPSG, PSG or the like. CONSTITUTION:A BPSG film 1 is deposited onto an Si substrate 8 on which a nitride film 2 is deposited, and the surface of the BPSG film 1 is smoothed through heat treatment. When a contact hole 13 is formed, only the BPSG film 1, an oxide film, is etched, and the nitride film 2 is left. Ions are implanted through the nitride film 2, and annealing is conducted at a temperature of 850-950 deg.C. A diffusion to the Si substrate 8 of phosphorus and boron from the BPSG film 1 can be prevented by the nitride film 2 at that time. An Al wiring and the Si substrate 8 can be brought into contact by removing the nitride film 2. Accordingly, an excess P-N junction, etc., are not shaped when the Al wiring, etc., are formed, thus acquiring low resistance.

Abstract: PURPOSE:For highly reliable, cost reduced colorimeter, a transparent body can be made free to be inserted in or extracted from sample liquid. CONSTITUTION:Sample cell 14 containing measuring liquid is located between a light source 11 and a photoreceptor 12. Transparent body 18 having a given length in the direction of photoaxis can be made free to move in and from the sample liquid. The light source 11 is turned on, and the transparent body 18 is moved up and down. This produces two states, one with the transparent body 18 being present, the other with liquid instead of the transparent body 18. The difference between two states, or the difference of absorbance between sample and the transparent body 18 corresponding its length is detected by the photorecepter 12. Such signal is more easy to be treated than conventional colorimeter where sample liquid must be changed in length, and results in simplified measuring instrument.
