IPC: G01M11/00
Filed: 1984-11-05
Abstract: PURPOSE:To achieve a higher reliability of a measuring data, by providing a light receiving section at a specified position of a cylindrical mirror body having a reflecting surface inside. CONSTITUTION:A cylindrical mirror body 1 is made up of a reflecting surface forming layer 3 in which a metal with a high reflectance of light such as Ag and Au deposited or coated on the circumferential surface of a transparent glass tube 2. An optical fiber 4 is forced into the mirror body 1 and a light receiving section 6 is provided at a specified position at one side end of the mirror body 1. Then, as the maximum quantity of light 9 leaked from the optical fiber 4 through which is passing from a light source 5 depending on the position of light at a fine angle to the axis of the optical fiber 4, very limited quantity of light is obtained only by bringing a photodiode, for instance, close to the optical fiber 4. Therefore, leaked light is reflected at the closest distance to the optical fiber 4 to collect with the mirror body 1. So to speak, the mirror body 1 prevents diffusion the leaked light to allow the collection of light. Moreover, the leaked light thus collected is fed to the light receiving section 6 to measure the quantity of the light.

Title: Controller for circulating pump for hot-water heating
Inventor: ISHIHARA TOSHIHIKO
IPC: F24D3/00
Filed: 1988-09-16
Abstract: PURPOSE:To accelerate the temperature drop of hot water, and to prolong the life of respective component parts by maintaining the operation of a circulating pump interposed on the way of a hot-water circulation system with the aid of a temperature sense switch during a period of time when hot water is at a higher temperature than a predetermined temperature even after an operation switch has been turned OFF. CONSTITUTION:Even after an operation switch 12 has been turned OFF, a circulating pump 4 maintains its operational state, with the aid of the work of a temperature sense switch 13, during a period of time when the temperature of hot water is higher than a predetermined temperature. Accordingly, hot water which is still in a high-temperature state immediately after a heating operation has been stopped, circulates through a hot-water circulation system. If a blower 7 is made to drive in accordance with this circulation of the hot water, heat- exchanging is effected by a heat exchanger 5 for hot air, and the temperature of the hot water in the hot-water circulation system is gradually decreased. Accordingly, the hot water at a high temperature does not stay in the hot-water circulation system for a long period of time, and the operation of the switches for the hot water, which are set in the hot-water circulation system, can be reduced accelerately. Therefore, the respective component parts in the hot-water circulation system are prevented from being deteriorated due to heat, thereby providing the component parts having a long and useful life.

Title: Device to regulate direction of air from air conditioner
Inventor: KUBO HIROAKI
IPC: F24F13/14
Filed: 1986-09-30
Abstract: PURPOSE:To make it possible to recognize the angle of a air direction regulating plate visually when the plate is being regulated by changing the display color of a photo-display section provided at the front end of the air direction regulating plate as it is changed over to room cooling position or to room heating position. CONSTITUTION:When an air direction regulating plate 2 is rotated upwards to the room cooling position side, blue light is emitted from a two-color luminous diode 7 and the blue light passes through an incident section 8a, photo- conduction face 8c and displays at a photo-display section 8b. On the other hand, when the air direction regulating plate 2 is rotated downwards to the position of room cooling, red light is emitted from the two-color luminous diode 7, and it is displayed in the same way at the photo-display section 8b. With this arrangement, since the display color at the photo-display section changes to blue or to red as the air direction regulating plate 2 is changed over to room cooling position or to room heating position, it is possible to recognize visually and clearly the angle of the air direction regulating plate 2 when it is regulated even if the inside of the room is dark or remote control is made, and this set-up is very convenient for use of the air conditioner.

Title: Wide band optical low pass filter
Inventor: YONEYAMA MASAYUKI
IPC: H04N5/357
Filed: 1991-09-12
Abstract: PURPOSE:To obtain required wide band low pass characteristics by holding an optical low pass filter(LPF) between 1st and 2nd reflection materials and allowing incident light to pass the LPF plural times while multiplexedly reflecting the incident light. CONSTITUTION:Incident light through the 1st reflection member 1 is reached to the 2nd reflection member 4 through a lambda/4 plate 2 and the optical LPF 3 with thickness (t). The prescribed quantity of the incident light is passed through the member 4 and the residual is reflected and returned to the member 1 through the LPF 3 and the plate 2. The member 1 totally reflects the light returned from the member 4 and the total reflection light is passed through the plate 2 and the LPF 3 again and then totally reflected by the member 4. Thus the light is passed through the LPF 3 plural times by multiple reflection between both reflection members 1, 4 and then outputted. Since a higher harmonic component in a Fourier component constituting low pass characteristics can be also obtained simultaneously with a reference wave, required wide band low pass characteristics can be obtained and resolution can be improved.

Title: Picture compression/expansion device
Inventor: UKAI YUKIHIRO
IPC: H04N19/167
Filed: 1994-09-28
Abstract: PURPOSE: To improve composite processing speed and to correspond to a video signal whose real time processing is difficult. CONSTITUTION: In the decoders 52 and 53 of variable length codes, processing speed is improved while the increase of hardware quantity is considerably suppressed by changing a processing method when the number of decoded data is one and when it is more than two.

A delay device 61 delays a data string including indefinite data and changes data from the large scale decoder 53, which is not delayed, into indefinite data to embed it. Thus, an indefinite part is compensated and the delay of a relative processing is prevented.
