Title: Structure of chamber for mixing cool air and hot air for air conditioner
Inventor: UDA AKIRA
IPC: F24F13/04
Filed: 1988-07-11
Abstract: PURPOSE:To improve the function to trap condensate by providing a water trap member shaped like a ring which covers the whole perimeter of the inner wall of the main body of a mixing chamber and forming a drain slit that pierces through the wall of the main body below the water trap member. CONSTITUTION:Below the main body 11 of a mixing chamber three air introduction ports 12 are formed substantially in the tangential directions with respect to the main body 11. The air that is introduced into the inside of the main body from the air introduction port 12 ascends as it whirls in the main body. The moisture that is contained in the ascending air is collected by the centrifugal force to the radially outside directions to form a water film on the surface of the inner wall of the main body 11. This water film is dragged by the ascending air in the main body so that the water film tries to ascend but a water trap ring 20 obstructs the ascending of the water film, and it forms a horizontal annular revolving flow below the water trap ring 20 and stays there. And, this revolving flow is discharged from a drain slit 21 to a water discharge pipe 22. The water in part of the water film flows downwards to reach the bottom of the main body 11, and this water is discharged from a discharge port 23 to a discharge pipe 22.

IPC: H04B14/04
Filed: 1988-07-12
Abstract: PURPOSE:To improve the S/N of an analog circuit formed on the same semiconductor substrate as a digital circuit by constituting a device so that the operation of the digital circuit can be stopped transiently when a prescribed operation is performed in the analog circuit. CONSTITUTION:In a one-chip type modem device on which the analog circuit consisting of an A/D conversion circuit ADC, etc., and the digital circuit consisting of a digital signal processing circuit DSP, etc., are loaded in consolidation, for example, the operation of the digital circuit is stopped transiently by not forming a clock signal supplied to the digital signal processing circuit DSP transiently while the sampling operation of an input analog signal is performed by the A/D conversion circuit ADC. In other words, the formation of clock signals (phi1-phi4) by a clock generation circuit CG2 are not performed transiently when a timing signal phi sp supplied from a digital phase locked loop circuit DLP1 is set at a high level. In such a way, it is possible to improve the S/N of the analog circuit.

Title: Tracking of maximum output power point in solar cell array
Inventor: SAWAI HIROYASU
IPC: G05D3/12
Filed: 1988-07-11
Abstract: PURPOSE:To always track a maximum output power point even when an output characteristic of a solar cell array contains a plurality of maximum output power points by a method wherein electric power values of the plurality of maximum output power points detected by using a prescribed method are compared and a maximum of the maximum power points is set as an operating point of the solar cell array. CONSTITUTION:A P-V curve first detects a point D by a mountaineering method when two maximum points D, F and one minimum point E are contained. For example, while an output voltage V is scanned from a low point to a high point, a point where a differential coefficient of the P-V curve is reversed from 0 or (+) to (-) is detected. After this maximum point D has been detected, the voltage V is then scanned to a high point and the maximum point E is detected. Then, a point where the differential coefficient of the curve is reversed from 0 or (-) to (+) is detected. When the maximum point E is found, another maximum point F exists; accordingly, another maximum output power point F is detected in the same manner. Magnitudes of the power points D and F are compared; a larger point is set as an operating point of a solar cell array. That is to say, the point F is a maximum output power point and the operating point.

Title: Hard disk drive
Inventor: OGUCHI TETSUO
IPC: G11B21/12
Filed: 1988-07-11
Abstract: PURPOSE:To always set a head to a floating state from a hard disk by holding the head in a state where the head is held in a non-contacted state in the vicinity of the outermost peripheral section of hard disk while the rotation of the hard disk is stopped. CONSTITUTION:When the use of a hard disk 1 is completed while a head 2 is held in a floating state, a supporting body 4 is retreated to the rear-most position while the disk 1 is rotated. Therefore, a plate spring 3 is press-expanded by the tapered surface of a comb teeth 6 while the head 2 is in the floating state and the head 2 is held in a non-contacted state. Thereafter, the rotation of the disk 1 is stopped. When the rotation of the disk 1 is actuated, on the other hand, the disk is started to rotate in the state where the plate spring 3 is press-expanded by the comb teeth 6 and, after the rotation is increased to a specific revolving speed, the supporting body 4 is moved toward the inner peripheral section of the disk 1. Since the relative speed between the head 2 and disk 1 becomes the one required for floating by dynamic life, the head 2 is held in the floating state and does not come into contact with the disk 1. Therefore, the head 2 can always be maintained in the non-contact state in the ordinary using state.

Filed: 1982-09-30
Abstract: PURPOSE:To reduce the generation of noise, by forming a contact section between an original and a photodetecting section of a contact type reader by an alumina single crystal to decrease scratches caused by sliding on the original. CONSTITUTION:An insulating film or light shield layer 8 is formed on a transparent base 7 and formed into a layer by leaving a light leading window 4; and a lower electrode 6, photoelectric member 5 and an input electrode 9 are formed.

Title: Touch detector
Inventor: ASANO TOORU
IPC: H03K17/96
Filed: 1981-10-29
Abstract: PURPOSE:To eliminate complicacy of the circuit constitution for a touch detector using a resonance phenomenon, by detecting the contact or non-contact of a detecting electrode in the form of change of a voltage value at the joint between  an impedance circuit and a resonance circuit. CONSTITUTION:A touch detector uses the resonance phenomenon of a resonance circuit to detect the contact or non-contact of a detecting electrode. For such touch detector, a detecting electrode 33 is connected to a resonance circuit 32 which is provided independently of an oscillating circuit OSC. Thus the contact or non-contact of the electrode 33 with a human body is detected in the form of change of a voltage value at a joint between an impedance circuit 31 and the resonance circuit 32. Therefore just a single resonance circuit can be equally used for plural resonance circuits in case a key input device is formed with plural touch detectors set in parallel to each other. This prevents the complicacy of the circuit constitution.
