Title: Drink supply machine
Inventor: KOBAYASHI MASAHIRO
IPC: A47J31/50
Filed: 1989-08-31
Abstract: PURPOSE:To improve the cooling efficiency by a simple structure by allowing a hot drink to flow down through a drink flow-down passage and bringing it to indirect cooling, and setting it to a state that it remains in the flow-down passage until a siphon phenomenon by a siphon tube is started. CONSTITUTION:Hot coffee used for cold coffee drops down into a pan 35 from an extraction port, and this hot coffee flows down through a spiral hot drink flow-down passage 37. On the other hand, water stored in advance in a cooling water tank 33 is cooled by a cooling coil 34, therefore, hot coffee which flows down through the hot drink flow-down passage 37 is brought to instantaneous cooling indirectly from both of an outer cylinder 36 side and an inner cylinder 38 side, and primary cooling is executed. Also, cold coffee which reaches the lower part of the flow-down passage 37 does not flow out immediately to a cold reserving container 42 from a siphon tube 43, the flow-down passage 37 is filled entirely with hot coffee dropping down to the pan 35, and when it exceeds the top part of the siphon tube 43, a siphon effect is started, and cold coffee brought to primary cooling flows into the bottom part of the cold reserving container 42. In such a way, cooling to a cold drink from a hot drink more effectively is executed.

Title: Control method for transmission right
Inventor: FURUYA YUKITSUNA
IPC: H04W84/08
Filed: 1985-10-11
Abstract: PURPOSE:To reduce the probability of mutual interference among stations by checking the presence or absence of an idle channel from the time of observation varied by the channel priority and using the idle channel. CONSTITUTION:The channel number of the highest priority is read out of a memory 17 when a transmitting request is received and a synthesizer 18 is set at a frequency accordant with said channel. Then the reception signal is converted into an intermediate frequency by the output of the synthesizer 18 and undergoes the wave detection through an wave detector 12. While the reciprocal number of a priority function is read out of the memory 17 and set to a counter 16. An integration circuit 13 integrates the output of the detector 12 for the time set to the counter 16 and delivers it to a deciding circuit 14. The circuit 14 decides an idle state of the circuit by the output of the circuit 13. Thus the integration is applied for a long time to the channel having the small priority function and an idle circuit is accurately decided. While the integrating time is reduced to the channel of the large priority function and therefore the waiting time is reduced. This reduces the probability of mutual interference among stations.

Patent JP-S6380605-A (JP)
Title: Differential amplifier
Inventor: NAKAMURA HIROSHI
IPC: H03F3/45
Filed: 1986-09-25
Abstract: PURPOSE:To hold a transistor(TR) in an active range at any time and to improve its responsiveness by providing an idling constant current circuit to a main constant current circuit across a diode. CONSTITUTION:Specific currents flow through the main constant current circuit 38 and 1st and 2nd idling constant current circuits 42 and 44 all the time. Therefore, even if the collector current of one of a couple of TRs 20 and 22 becomes maximum owing to a large input, an idling current flows between the collector and emitter of the other TR 22, so the TR 22 is never turned off. Consequently, the couple of TRs 20 and 22 are invariably in their active ranges against a large input and the response of this amplifier never deteriorates.

Filed: 1989-09-01
Abstract: PURPOSE:To improve the contrast on the projection surface by allowing a direct light from an indoor illuminating light source to have a polarization characteristic being different from a polarization characteristic of the projection surface. CONSTITUTION:An image reproduced on a liquid crystal panel 1 is illuminated by a projection light source 3, and projected onto the projection surface 6 by a projection lens 2, and in this case, the projection light becomes a polarization state being parallel to a polarizing plate 4 by a polarization characteristic indicated with an arrow 12, therefore, it can nearly pass through the polarizing plate 4. On the other hand, a direct light from an indoor illuminating light source 7 becomes a polarization state being vertical to the polarizing plate 4 by a polarizing plate 8, therefore, it can scarcely pass through the polarizing plate 4. In such a way, even when a person present executes a necessary indoor illumination in order to take a memo, etc., an image having a satisfactory contrast is obtained on the project surface by a video light from a display device.
