Abstract: PURPOSE:To improve printing speed by removing heating of a printing head, by a method wherein a heat absorption part of a Peltier element is thermally connected to a driving coil to be established on an outer peripheral part of the printing head, and they are cooled by controlling a driving current of the Peltier element with a temperature sensor and a humidity sensor in a printer case. CONSTITUTION:A heat absorption part of a Peltier element 102 provided on an outer peripheral part of a printing head 101 is thermally connected to a driving coil composed of a superconducting material. The Peltier element is driven with a Peltier element controller 103, and signals from a temperature sensor 104 and a humidity sensor 105 are inputted to the Peltier element controller. When a printer is actuated, the Peltier element is firstly operated with the Peltier element controller to cool the driving coil to not more than a critical temperature and thereafter, the printer sends a ready signal and printing becomes possible. In service time, a temperature of the driving coil is always monitored with the temperature sensor, and driving current to the Peltier element is so controlled with the controller as not to reach not less than the critical temperature.

Title: Diamond cutting wheel
Inventor: SUGIURA SEIJI
IPC: B24D5/12
Filed: 1980-01-17
Abstract: PURPOSE:To improve the cooling effect of the diamond cutting wheel and facilitate the removal of chips produced by grinding by a method wherein the plural number f teeth are formed on the periphery of the cutter and a channel for flowing air is provided by cutting on the base of the tooth in the desired shape. CONSTITUTION:The plural number of teeth 3 are formed on the periphery of a blade 2 on which diamond powder 1 is attached by means of electrodeposition, and a chamber 4 is provided at the end of the tooth 3, while a crescent-shape cutout is prepared on the base of the tooth 3. When FRP material etc. are cut with a diamond cutting wheel thus shaped, the acdion of the teeth 3 and cutout 5 followed by the revolution of the blade 2 causes air flows a-c. The cooling effect in the cutting portion generated by the air flows a-c makes a cooling agent unnecessary. In addition, chips resulted from cutting is dispersed by the air flow, which prevents clogging and burning and prolongs the life of the wheel 2. This also improves the finish of the ground surface and grinding capability.

Title: Optical switch
Inventor: NAITOU HATSUHIKO
IPC: G01R19/145
Filed: 1980-01-16
Abstract: PURPOSE:To make a light beam incident to the interface of two electrooptical crystals permeate or reflect according to change of an applied electric field, by fitting together these crystals to make their polarization directions different. CONSTITUTION:Two electrooptical crystals A and B consisting of, for example, LiNbO3 where polarization directions are different by 180 deg. electrooptically are fitted together in face PZX making angle alpha(=1.4 deg.) for face PZ1. When a voltage is applied across PY1 and PY2 of plate 1, the refractive index is different in A and B due to the electrooptical effect, and difference DELTAn of the refractively between them becomes large, and therefore, the refrectivity of light beam B0 incident to face PZX at angle alpha (the reflection light beam is B1) becomes large. When the applied voltage exceeds 2,100V, the reflectivity changes rapidly as shown in the figure. Consequently, most of light beam B0 permeates the fitted face for voltage 0 and is reflected for voltage 2,100V or more, and thus, the light path is switched.
