Abstract: The operational temperature TP is determined as a function of the compartment temperature Tr. The blower speed is controlled along the characteristic line, the slope of which varies with the operational temperature TP. When the temperature of engine cooling water reaches a predetermined temperature, the speed of the blower is increased along the slope corresponding to the compartment temperature Tr. When the operational temperature TP is at least the predetermined temperature Tl, the speed of the blower is controlled as a function of time so that any violent increase in the blower speed may be prevented.

The thin slot has a length and a width which are greater than the shear ends.

Abstract: An electrical contact pin has a fixing part to be fitted into a through hole of a circuit board for fixing without using any solder. The fixing part has a substantially rectangular cross section. A pair of alternating recesses are provided on opposite sides of said rectangular section. A pair of corners closer to said recesses extend beyond said sides to form a pair of projected corners. A process for manufacturing such an electrical contact pin is characterized by the step of pressing a metal work having a substantially rectangular cross section to form said fixing part in a pair of metal dies. A pair of projections are provided on the bottoms of said dies to form said recesses. A pair of opposite sides of said dies are arranged so that there may be small spaces between said pair of sides and the opposite sides of said work before pressed. A part of said bottom of each die is made deeper than the rest of said bottom so as to form said projected corner when said work is squeezed.

Abstract: An apparatus for controlling a vehicle air conditioner having a speed setting mechanism interconnected to the output shaft of an actuator for turning an air mixing shutter so as to switch the blower between low and high speed operations. The cam mechanism has the first rotary part interlocked to the output shaft of the actuator and a response part in response to the rotary part to turn the air mixing shutter. When the output shaft is turned within a predetermined rotary range c set narrower that the entire rotary range of the output shaft, the air mixing shutter can be turned between full cooler and heater positions. The speed setting mechanism brings the blower to a low speed operation when the rotary angle of the output shaft falls within the rotary range c and to a high speed operation when the rotary angle of the output shaft falls outside the rotary range c.

Abstract: A compact hybrid stethoscope comprises a detachable headpiece for picking up auscultory sounds, a flexible tubing pneumatically connected to the headpiece for transmitting the auscultory sounds, an amplifier unit pneumatically connected to the flexible tube for receiving the auscultory sounds and reproducing amplified auscultory sounds, and a pair of auricles pneumatically connected to the amplifier for transmitting the reproduced sounds to the user's ears. An automatic on/off timer switch is connected to the amplifier so that even if inadvertently left on, the on/off timer automatically switches off the hybrid stethoscope after a predetermined interval, thus saving electric power. A tone control is connected to the amplifier so that the user may listen to the particularly desired auscultory sounds, such as respiratory or cardiac sounds while eliminating certain other auscultory sounds.
