Title: Protecting method of thyristor inverter
Inventor: SHIBUYA TADASHI
IPC: H02M7/515
Filed: 1978-12-27
Abstract: PURPOSE: To prevent commutation failure at the time of the short-circuit of a load by giving the output of a zero-cross sensor, wherein a sensed signal of a load voltage is given, to a gate-output-stopping circuit containing mono-multivibrators and a memory, thereby controlling thyristors.  
     CONSTITUTION: In the case power is applied to an induction heating tank circuit LR from thyristor circuits ST 1  and ST 2 , a load voltage is sensed by a transformer DT and supplied to comparators CP and zero-cross sensors ZC, and the outputs therefrom control the triggering pulses of the thyristors. The output from the sensors ZC are sent to a memory MR by way of monomultivibrators MM and NAND gates NAND, and the output of the memory MR sends a gate-stopping signal to gate circuits GA. Therefore, at the time of the short-circuit of the load circuit LR, since the gate is stopped by the increase in resonant frequencies and the thyristors are not turned on, the occurrence of commutation failures can be perfectly prevented.

Title: Improving initial adhesion of veneer adhesive
Inventor: TAGUCHI JIYUN
IPC: B27D1/04
Filed: 1978-12-28
Abstract: PURPOSE: To enhance initial adhesion of veneer by a method wherein granular carboxymethylcellulose particle is partially dissolved as thickner when coating adhesive on the veneer, and viscosity is increased as time passes by water present in the adhesive.  
     CONSTITUTION: To 100pts.wt. of synthetic resin which forms the main component of veneer adhesive, such as urea resin or melamine resin, about 0.5wt% or less of granular carboxymethylcellulose (CMC) is added immediately before adhesive coating on veneer as a thickner. This reduces viscosity of the adhesive when coating on the veneer, and thus facilitates coating operation. After coating, CMC is dissolved by water present in the adhesive, and rapidly increases the viscosity of adhesive, thus enhancing initial adhesion of the veneer.

Title: Permanent magnet type linear pulse motor
Inventor: KOMATA HITOSHI
IPC: H02K41/03
Filed: 1987-07-03
Abstract: PURPOSE:To increase thrust force by forming the teeth faces of primary and secondary cores to be relatively moved at a predetermined air gap in a crest shape in a direction perpendicular to the moving direction. CONSTITUTION:Poles 7, 9, 11, 12 for forming 4 primary cores of a movable element 3 are formed in crest shape symmetrical at the lower tooth face and the face for placing an upper permanent magnet with respect to a center line CL. Similarly, the tooth face of a stator 5 is formed in a crest shape symmetrical with respect to the CL, and faced with the tooth face through an air gap delta. Then, since the teeth of the movable element 3 and the stator 5 are mounted at a predetermined phase difference, they can be fed stepwise by energizing a coil. When a force acting on the tooth face opposed thereto at this time is P, upward and downward attraction forces become Pcos theta. Horizontal attraction force becomes Psin theta, but since the teeth faces are symmetrical with respect to the center line CL, they are cancelled to the symmetrical teeth faces. Thus, since the upward and downward attraction forces are alleviated, its thrust force can be increased.

Title: Cereal temperature detector for cereal drier

IPC: F26B25/00
Filed: 1987-07-01
Abstract: PURPOSE: To obtain a grain temperature without direct contact with a grain by calculating the grain temperature from a total sum of values obtained by multiplying measured values of a hot air temperature sensor and an exhaust air temperature sensor by respective constants, and altering the constants to predetermined values at the time of ventilating the atmosphere. CONSTITUTION: During a hot air drying period, a hot air temperature TB is measured by a hot air temperature sensor 25, an exhaust temperature TE is measured by an exhaust temperature sensor 24, and a grain temperature TG is calculated by a formula (1) of TG=K1.TB+K2.TE, wherein K1 and K2 are experimentally and empirically obtained constants. At the time of hot air drying, it is, for example, K1=1/8, K2=7/8. Even during atmospheric ventilating time, the temperature TG is calculated by the formula (1). However, at the time of ventilating the atmosphere, the constants are K1=1/8, K2=1. That is, when it is shifted to the atmospheric ventilation, an operation of a burner 10 is stopped. Accordingly, after several min, hot air temperature TB of the hot air chamber 6 becomes substantially equal to the atmospheric temperature.  And, since the atmospheric wind passes the warmed grain in a drying chamber 5, an exhaust temperature TE of an exhaust chamber 8 becomes her than the atmospheric temperature.
