Title: Solidification of bark or saw dusts
Inventor: MIYATA HIDEO
IPC: C10L5/44
Filed: 1980-07-07
Abstract: PURPOSE: The compression molding is conducted after or as a moisture-curable adhesive is added to barks or saw dusts to produce deformation-free fuel with no drying treatment in low costs.  
     CONSTITUTION: Resins and/or wood chips are cut into sizes suitable for conveying and charged by means of a belt conveyor into the hopper 1 of the compressor.

Title: Oscillating device
Inventor: MOCHIDA SUGURU
IPC: B01F11/00
Filed: 1978-07-29
Abstract: PURPOSE:To make the oscillation mechanism simple and enable observation of mixing condition, etc. to be accomplished under the optimum condition by three- dimensionally oscillating an oscillating plate through supporting of the oscillating shaft of the oscillating plate to the device body by way of a universal joint and providing a means of stopping the oscillating plate in the front position. CONSTITUTION:Slide glass 15 is set onto an oscillating plate 2 and reagent and sample are dropped. When the oscillation timer is set to a timer 9 and a driving means 8 is operated, a rotary disc 5 rotates, causing an oscillating shaft 3 to make oscillating motion by way of a pin 6. As a result, the oscillating plate 2 makes three- dimensional oscillation, whereby the liquid and sample are mixed. As the set time of the timer 9 elapses, a switch 9a opens and current flows through the circuit of a switch 10, causing the rotary disc 5 to rotate. When an operating piece 11 comes to the position of the switch 10, the current is cut off and the rotation of the oscillating plate 2 stopped. At this time, the oscillating plate 2 is facing the front position and therefore the mixing condition may be observed in the optimum condition.

Title: Selective calling receiver
Inventor: NAKAZAWA TAKEO
IPC: G08B3/10
Filed: 1988-04-15
Abstract: PURPOSE:To eliminate the need of the mounting and removing operations of a battery so as to improve the operability of the title receiver by transferring the individual number code of one's own receiver to a memory by operating an operation mode designating switch. CONSTITUTION:If a switch 11 is operated after an ID memory 5 is changed, a switching signal MS is outputted from a calling mode detection circuit 10 to a call control circuit 6 and collation circuit 40. When a call to one's own receiver is issued thereafter, the calling mode is switched from the ordinary mode to the soundless calling mode and a readout signal is outputted from the collation circuit 40 to the memory 5. As a result, an individual number code is read out from the memory 5 and written in the circuit 40. Therefore, calling information is performed by ringing sounds and flickering of light when the new individual number code arrives from a base station thereafter.

Title: Knocking control device
Inventor: TANAKA SEIGO
IPC: F02P5/152
Filed: 1990-04-09
Abstract: PURPOSE:To perform knocking control with a slight error operation by correcting a knocking judging coefficient while utilizing two kinds of backgrounds whose difference is enlarged at the knocking generation. CONSTITUTION:A computer 105 reads an A/D value of an A/D converter 104 under a timing that an output VP of a peak hold circuit 103 is stable. In the computer 105, two kinds of backgrounds are computed for controlling an ignition timing. The first background, changed according to the A/D conversion value VP, is small when a noise alone is generated, and increased when a knocking occurs. The second background, changes similarly to the first background when the A/D conversion value of this time is small. However, when it is large, the second background changes in a different form from that of the first background. When knocking occurs, a difference between the first and the second is reflected to a knocking judging coefficient. The knocking judging level is made to be variable value in order to prevent the generation of knocking.
