Abstract: PURPOSE:To eliminate the troubles such as separation of soldered part by a method wherein a flattened tube on the outermost side of a boss of a multiplate heat exchange element is offset inwardly and soldered to the boss and said boss is welded to a wall of a casing at a point spaced from the soldered part. CONSTITUTION:A heat exchange element 3 fitted in a casing 1 comprises a large number of plates 4 stacked in layers, wherein the plates 4 are combined together two by two and the periphery of the combined plates 4 are sealed to form a flattened tube 5. The tubes 5 are vertically arranged, spaced a predetermined distance (d) from each other, and on the upper surface of the uppermost tube 51, there are provided bosses 9a, 9b just above headers 8a, 8b. In said element 3, the tube 51 is provided at a position offset downwardly by a distance approximately equal to the distance (d). As a result, the length from a soldered part 10 of the boss to the welded part is made longer, preventing thereby the heat of the welding from exerting a bad influence on the part 10.

The first reference image on the photoreceptor 1 is developed only by the first developing roll 53 to obtain a first visible image, a sensor read its image density, and a control unit finds the first toner sticking amount and drives the exposure device to form first and second reference images. A second visible image is formed by developing the second reference latent image by using first and second developing rolls 53 and 55, and the sensor reads the image density to find the second toner sticking amount.  The development partial charge rate of the first and second developing rolls 53 and 55 is found from the difference between the first and second toner sticking amounts to change the image formation conditions.

Filed: 1983-09-30
Abstract: PURPOSE:To obtain a virtually rewritable optical disk device by handling a write error which is caused by rewriting equally to a write error due to a defective spot on an optical disk surface. CONSTITUTION:Write data is written in a block of an optical disk address specified by a host computer 1. The written data is compared with write data read out of the block to check on the occurrence of a compare error and an ECC error; when neither error occurs, it is judged that the correct write data is written in the optical disk address and the operation is completed. When either error is detected, the optical disk defective block address field 01 in c control table 1 is searched to check whether the data is already written or not; when it is already registered, this shows that rewriting to this block is performed before, so the write data is recorded in a magnetic disk address indicated by a magnetic disk address field M1 and a flag F1 is set.

Abstract: PURPOSE:To perform dehumidification or the like in a car room favorably without using cooling air, by performing the temperature regulating operation of blowoff air forcedly irrespective of temperature of the detected outside air, at a time when cooling operation is detected simultaneously with detecting inside air circulating operation. CONSTITUTION:When a damper 9 inside a duct 1 closes the outside air side and an inside air mode switch 23 is in an on-state, if an air conditioner switch 21 is turned on and an output terminal 35a of a cooling start circuit 35 comes to an on-state, a timer circuit 39 comes to an on-state as long as the specified time owing to work of an AND circuit 38. If so, a transistor Tr2 comes to ON as long as the specified time, whereby a holding relay 33 comes to an on-state as well. In consequence, since a magnet switch 29 comes to an on-state as long as the specified time after bypassing a low pressure device 27, a compressor 17 is driven so that dehumidification operation is started. That is to say, this inside air mode's dehumidification operation is forcedly performed as long as the specified time even if the low pressure device 27 is in an off-state.

Title: Field effect transistor and manufacture thereof

IPC: H01L29/78
Filed: 1993-06-30
Abstract: PURPOSE:To provide a field effect transistor(FET), which has the structure capable of achieving high integration density and suitable for mass production and can perform highly. reliable high-speed operation. CONSTITUTION:A crystallized Si layer 4c is conformally formed so as to cover a groove 3 opened in an SiOx interlayer insulating film 2. After a gate electrode 6 is formed on the central step, slant ion implantations in two stages where the implantation angles are made different are performed with the electrode 6 as a mask. Thus, the source/drain region comprising a high-concentration impurity diffused region 7 and an LDD region 8 is formed in the self-aligning mode. Thus, the source/drain region is extending in the longitudinal direction with respect to the surface of a substrate. Therefore, the achievement of high- integration density is possible, and a short channel is hard to occurr. The gate electrode 6 is effective only in the region, wherein the electrode is emhedded in the groove 3. Therefore, the length of a channel Ch1 can be shortened exceeding the resolution limit of lithography, and the transistor becomes advantageous for the high-speed operation.
