Patent JP-S63269487-A (JP)
Title: Kitchen utensil
Inventor: HATTORI KENJI
IPC: H05B6/12
Filed: 1987-04-27
Abstract: PURPOSE:To facilitate operation and prevent damage of a top plate by providing a table with a switching means for controlling drive of an induction heating device. CONSTITUTION:A table 3 is put on the surface 1 of a top plate, and subject matter 8 is put on it. When the switch of a manual switch means 4 in the table is put on, a generating device assembled in it gets on, and the signal is received by a receiving device 5, so as to actuate an induction heating device 2. Lines of magnetic force generated from an induction heating coil 6 start heating the subject matter 8, and heat is duly conveyed to the table 3, and then to the surface material 1 of the top plate. It is possible, therefore, to direct a switch part in any direction, and operability is improved, while at the same time appearance becomes better since use without a table is impossible, where damage and scorching of a top plate caused by directly putting a pot on the top plate can be prevented.

Title: Control of ink concentration
Inventor: KAWAKATSU OSAMU
IPC: B41F31/02
Filed: 1981-07-02
Abstract: PURPOSE:To enable stable retention of an ink at an accurate concentration by adjusting the supply of a solvent with the opening or closing of a valve detecting variation in the viscosity of an printing ink in terms of a change in the rotary torque of a rotating disc in a tank. CONSTITUTION:A disc 5 in an ink 1 driven with a motor 6 receive a resistance from the viscosity of an ink and with the variation of the ink concentration, the load of the driving motor 6 changes. Therefore, the variation in the driving current of the motor 6 is converted into a control signal with a controller 7 to open or close a control valve 8. This allows the adjustment of the quantity of a solvent 3 to be supplied to an ink tank 2 thereby invariably maintain a constant concentration of the ink. The rotating disc 5 also provides an agitation effect to uniformize the ink concentration in the tank 2.

Title: Color measuring device
Inventor: NAKAGAWA TOSHIHISA
IPC: G01J3/50
Filed: 1991-02-22
Abstract: PURPOSE:To improve measurement sensitivity by increasing the light quantity of the measuring light carrying the color information of a sample and fed to a detector in the color measurement of the transparent or semi-transparent sample such as a gem. CONSTITUTION:A sample 1 is covered with an irregular reflecting plate 3 having a white inner face, and all the sample transmission light is reflected by the irregular reflecting plate 3. When the reflected light is again fed to the sample 1, the sample transmission light, as well as the internal scattered light in the sample 1, is again transmitted, the light quantity fed to the detector 5 is increased, thus the same effect is attained as that the thickness of the sample 1 is made twice or above.

IPC: B28B21/70
Filed: 1988-04-28
Abstract: PURPOSE:To make a split pipeline suited to the needs layable at once by inserting a separation plate into the inner part of a circular or ovate concrete pipe and fixing it therein, while dividing the pipe inside into a split passage lengthwise or breadthwise. CONSTITUTION:Both end faces 3a, 3b of a separation plate 3 extended in the longitudinal direction are made contact with the surface of an inner wall 4a of a large diametral concrete pipe 4 forming its section into a round form, fixing this separation plate 3 thereto. This concrete pipe will be good enough even if it is a special form pipe such as an ovate one or the like and a small diametral pipe. Also the separation plate is indifferent to being breadthwise and of plural numbers. In addition, it is no matter where an insert hole 12 for a precast steel bar or the like is installed. In consequence, more than two or three split passages are formed in the inner part of the concrete pipe in a vertical or horizontal direction. Since this concrete pipe is not subjected to any concrete placing, the worsening of a flow due to deformation in the inner bottom and sedimentation, clogging are in no case produced there.
