Inventor: NUMAJIRI FUMIYA
IPC: F24H7/04
Filed: 1988-11-17
Abstract: PURPOSE:To enable manufacture of a system the cost of which is low by a method wherein the heat exchanger of a heat pump and an air conditioning radiator are arranged in juxtaposition symmetrically about a heat accumulating tank through piping, and a piping circuit is formed only with a brine pump and a three-way valve in addition to the heat accumulating tank. CONSTITUTION:Brine 12 is used as a heat transfer medium in order to accumulate heat and emit heat.

Title: Electrooptic device
Inventor: TSUNODA YUKIYOSHI
IPC: G02F1/1365
Filed: 1987-11-18
Abstract: PURPOSE:To prevent generation of an abnormal display state by providing dummy electrodes to the parts of the spacings between picture element electrodes where line electrodes do not face each other. CONSTITUTION:This electrooptic device is constituted of row electrodes 1, the line electrodes 2, picture element electrodes, nonlinear elements 4, a liquid crystal layer 5, and the dummy electrodes 6. The nonlinear elements 4 are constituted by forming films having nonlinear characteristics in place between the line electrodes 2 and the picture element electrodes 3. Although a strong potential difference is generated in the extremely narrow regions between the row electrodes 1 and the dummy electrodes 6 when the dummy electrodes 6 are provided between the picture element electrodes 3 and 3, the potential of the dummy electrodes 6 is constant in the greater part of the regions and, therefore, the potential gradient by the potential difference of the row electrodes 1 is extremely small and electric fields are as shown by arrows. The parts where the liquid crystal is moved by the presence of the potential difference between the row electrodes and an abnormal display arises are confined to extremely narrow regions. The generation of the abnormal display state is thereby prevented.

Title: Image synthesizing device
Inventor: HIROSE MAKOTO
IPC: G06T3/00
Filed: 1987-11-17
Abstract: PURPOSE:To eliminate unnaturalness at the boundary part of a synthetic image by generating the synthetic image by referring to similarity in two images in an area within a certain distance from the boundary of the two images in case of synthesizing binary images. CONSTITUTION:The synthetic image can be generated by detecting 26 the similarity by comparing the small areas of plural images to be synthesized, comparing 27 the similarity with a threshold value TH, and connecting the small areas which satisfy a prescribed condition. At this time, since the threshold value TH is changed corresponding to the distance from the boundary, a part between two image signals can be interpolated smoothly. In such a way, it is possible to synthesize the natural images of the binary image considered hard to generate in an on-going device, and to eliminate the unnaturalness in the boundary even in case of synthesizing the binary image having meaning in one image element like a character or a line drawing and the binary image in which light-and-shade is expressed by plural images like an image on which a dither processing is applied.

Patent JP-H10170841-A (JP)
Title: Eyepiece
Inventor: KONISHI KOICHI
IPC: G02B25/00
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To correct such aberration as chromatic aberration, curvature of field, and spherical aberration well with an inexpensive lens system constituted of a small number of lenses, by constituting an eyepiece of one gradient index lens, whose refractive index is changed in accordance with distance in the radial direction from an optical axis and whose medium power is negative. SOLUTION: The eyepiece is constituted of a radial type GRIN lens, and the medium power of the eyepiece is negative, so that the curvature of field can be compensated without the negative power on a lens surface. In this case, since the respective surfaces have positive power and the respective surfaces can share the power, the amount of aberration occurring on each surface can be made small. That is, the medium has the negative power, so that the various kinds of aberration including the curvature of field can be compensated well with the small number of lenses. Thus, the chromatic aberration and the curvature of field can be corrected even with one radial type GRIN lens.

Abstract: PURPOSE:To measure the far infrared radiation energy quantum of an action being effective for heating of food and drink by using a filter for allowing only infrared rays whose wavelength area is >=2mum to transmit through, and also, having a roughly constant transmission factor against infrared rays of this area. CONSTITUTION:A pyroelectric current outputted from a pyroelectric element 2 is amplified in accordance with a range selected by an amplifying circuit 10, cut as to its low frequency by a low-pass filter circuit 20, and thereafter, converted to a DC by an AC/DC converter 30 and displayed 40. In this regard, the pyroelectric current outputted from the element 2 corresponds to a difference of the infrared radiation energy quantum from a chopper 6 and a heat radiation body A. Accordingly, by taking out its pyroelectric current from the converter 30 in the end, the infrared radiation energy quantum from the heat radiation body A is displayed as an infrared radiation illuminance on an indicator 40, based on a black body of a constant temperature as a reference. Also, a filter 3 has a roughly constant transmission factor against infrared rays whose wavelength area is >=2mum, therefore, a far infrared radiation having an action effect peculiar to heating of food and drink is measured effectively.

Title: Semiconductor wafer dicing equipment
Inventor: OZAWA ATSUSHI
IPC: H01L21/78
Filed: 1992-10-06
Abstract: PURPOSE:To enables automatically setting individual dicing positions on a semiconductor wafer. CONSTITUTION:Dicing marks 1a are made on center lines in the dicing areas on a semiconductor wafer 6a. A fixed point A in the front row in the Y direction on the wafer 6a is recognized by means of a pattern recognition camera, and dicing is started. Dicing marks 1a in the second row are scanned during or after the dicing in the front row and recognized by lines in the dicing areas. Dicing positions are thus automatically detected, and further dicing is executed. The same steps as above are repeated in the X direction using a fixed point B as the reference point. This prevents accumulated pitch errors in dicing position and defects caused by operators' erroneous setting.

Abstract: PURPOSE: To enable transmission while suppressing the order reversal of data as small as possible even when plural transmission lines are connected to a transmission destination by allocating the data to the transmission line of high priority among the plural transmission lines. CONSTITUTION: From the data allocation part 23 of an X.25 (DTE) interface 22 in a multi-protocol router 2 to the multi-protocol router 3, logical channels 51a-51c within a relay channel 41 are connected between the multi-protocol router 2 and a packet switching network 1 and the logical channels 52a-52c within the relay channel 42 are connected between the packet switching network 1 and the other multi-protocol router 3.
