Title: Reinforced plastic resin box and its production
Inventor: SATO NOBUO
IPC: B29D22/00
Filed: 1986-12-17
Abstract: PURPOSE:To obtain a reinforced plastic resin box, by a method wherein reinforced plastic resin layers are superposed to the front and back surfaces of a core material having a large number of through-holes provided and arranged thereto over the entire surface by drilling, and bonded and unified through the through-holes. CONSTITUTION:A reinforced plastic resin box is provided. That is, a desired box body is formed of a wood plate such as plywood or a cardboard in place of forming a mold and a large number of through-holes 4 are uniformly arranged to the wood plate or cardboard 3 over the entire surface. In this case, the through-holes 4 may be provided by drilling before the box body is formed. Reinforced plastic resin liquids 5, 5' are applied to the front and back surfaces of the box body and the front and back reinforced resin layers are connected and unified through the through-holes 4 to compensate the trouble of the adhesion between the reinforced plastic resin and the wood plate or cardboard.

Title: Ball returning device for pachinko game
Inventor: TAKEUCHI MASAHIRO
IPC: A63F7/02
Filed: 1991-10-21
Abstract: PURPOSE:To provide a ball return device, which can eliminate wasteful circulation of balls. CONSTITUTION:In the condition that award balls to be returned for are stored in a ball return device 50 to actuate a full-tank sensor 57 and that award balls are stored in an upper tray 25 to cause actuation of an upper tray sensor 27, the numerical value corresponding to the number of award balls discharged on the basis of the signal given by prize winning sensors 23a-23g is displayed on a number-of-balls display 66 furnished in the ball return device 50 when an award ball discharge device 35 is kept off operation. This precludes wastefull circulation of balls, lessens the number of balls used per pachinko machine 20, and lessens in turn the number of provided balls in accommodation in the base 1 of each machine. Omission of wasteful circulation of balls can prolong the lifetime of the apparatus provided in association with ball circulation and also decrease the power to be consumed thereby.

Title: Leakage detection for pipeline
Inventor: ONISHI YASUNORI
IPC: G01M3/28
Filed: 1988-11-30
Abstract: PURPOSE:To detect a small leakage accurately by a method wherein a pressure gradient is determined between specified measuring positions using a measured pressure value obtained with a manometer and a leakage is determined to occur in a pipeline when a value of the pressure gradient is deviated from a predetermined range. CONSTITUTION:Pressure values measured with a plurality of manometers 21-26 set on a gas pipeline 1 are inputted into an input circuit 3 to be transmitted to an A/D converter 4 and the measured pressure value transmitted from the input circuit 3 is converted into a digital signal to be transmitted to an arithmetic circuit 5 of a computer 8. With the arithmetic circuit 5, based on the measured pressure value, a pressure gradient is calculated to be transmitted to a judging circuit 6, which 6 judges the presence of a leak caused based on the pressure gradient. As a result, when the presence of the leak is determined with the judging circuit 6, a leakage signal is outputted from an output device 7 as external indication signal and a display is performed by a symbol, a lamp or the like.

Filed: 1988-11-30
Abstract: PURPOSE:To improve transmission quality by providing the calculating means and the synthesizing means of branch-metric and a viterbi algorithm operating means, and calculating the branch-metric from a received signal, and synthesizing those. CONSTITUTION:The branch-metric calculating parts 61, 63 calculate the branch- metric of detection signals obtained respectively by orthogonal detecting parts 55, 57 according to a reference signal generated from a reference signal generating part 59.

Title: Photo-conductive toner
Inventor: ANDO TOMIO
IPC: G03G9/08
Filed: 1990-11-08
Abstract: PURPOSE:To output an image in high quality by letting photo conductive toner be of electret property in order to keep the toner electrically charged semi- permanently. CONSTITUTION:Photo conductive toner is made up of a core 1 composed of fixing resin medium in which electric charge transport material 3 is dispersed, and of an outer shell 2 including photo conductive material 4 with which the surface of the core 1 is covered. Electric charge in reverse polarity is kept at both the sides of the shell (the upper and the lower section in the figure) with electret property imparted. Since photo conductive toner is thus constituted, if light is exposed on it, electric charge is generated by the photo conductive material 4, the electric charge is propagated while the electric charge transport material is acting as a carrier, electric charge which is kept semi-permanently by electret property at both the sides of photo conductive toner, is thereby neutralized. As a result, the quantity of electric charge of disposed toner is reduced, it is thereby possible to select photo conductive toner on the basis of the transfer or removal of an image section or a non-imaging section.

Title: Thickness measurement for resist film
Inventor: ARAKAWA MITSUMASA
IPC: H05K3/06
Filed: 1987-12-01
Abstract: PURPOSE:To accurately discriminate an area coated with a resist film from the field of view of a microscope, by embedding a base material into a resin in such a manner that the surface thereof coated with the resin film is previously coated with a color more in the quantity of reflected light than the resist film. CONSTITUTION:A white oil paint 14 with more quantity of reflected light is applied on a base material 12 coated with an almost transparent resist film 11 having a light green color with a pen, a brush 13 or the like.
