IPC: F28F3/04
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger, capable of securing necessary heat transfer performance by only heat transfer plates, constituting refrigerant passages, without necessitating any fin, such as a corrugate fin or the like. SOLUTION: A heat exchanger is constituted so that two sheets of heat transfer plates 12, having a multitude of projected parts 14, are connected under a condition that the projected parts 14 are faced outward to each other and a superposed part is provided between the projected parts 14 to constitute refrigerant passages, conducting refrigerant to flow therethrough, while air- conditioning air, flowing through the outside of the heat transfer plates 12, is conducted to flow into a direction A, orthogonal to the flow direction B of the refrigerant, whereby the projected parts 14 are employed as turbulence generators, which hinder the straight flow of airconditioning air and generate the condition of turbulent flow.

Title: Input unit
IPC: G06F3/033
Filed: 1992-07-20
Abstract: PURPOSE:To provide the input unit overcoming the drawback of a mouse and permitting an unskilled operator to direct the coordinate shift with a simple operation. CONSTITUTION:A table 1 with electrodes 1y in the Y direction arranged under an upper sheet 1A and with electrodes 1x in the X direction arranged on a lower sheet 1B. When touching the tablet 1 by hand, the electrodes 1y and 1x are come into contact with each other corresponding to the pressing section. The electrodes 1y and 1x of the tablet 1 are connected to a scanning circuit 2 to detect the contact information of the electrodes 1y and 1x and the contact information of each frame is stored in RAM 3. Based on the contact information of the current frame stored in the RAM 3 and the contact information before one frame, CPU 5 and 6 discriminate the coordinate shift input and switch input, and transmits the result to the computer or to the keyboard through an interface circuit 8. As the operation is as simple as just moving a finger touched on the tablet 1, it is easy for an unskilled operator. The drawback of a mouse slowing down the operation due to the dirt of a ball can be eliminated.

Title: Image pickup device
Inventor: MATSUZAKA KAZUHIRO
IPC: G03B5/00
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of an image owing to an enlargement operation to a minimum even if a high speed enlargement function is provided by controlling first and second control means and deciding the angle of view. SOLUTION: When a view angle desired by a user is transmitted to a system control circuit 101 by a zoom switch 110 and zooming for obtaining the desired image angle is in the direction of Tele, the system control circuit 101 makes an AF micro computer 102 and an electronic zoom micro computer 111 drive the optical zoom and the electronic zoom in the direction of Tele until they reach the desired view angle at the same time. When they reach desired magnification, the electronic zoom is driven to the direction of Wide and the optical zoom to the direction of Tele in opposite directions. Thus, magnification control by the optical zoom is made dominant. Thus, high speed zoom is realized by driving the electronic and optical zooms being the second and first control means to the desired view angle.  Then, the control of the view angle is shifted to the optical zoom and therefore the photographic image can be obtained with satisfactory resolution.

Title: Production of hydroxyapatite platelike large-sized crystal
Inventor: WAKANA MINORU
IPC: A61K8/00
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To produce a hydroxyapatite platelike large-sized crystal under comparatively mild reaction conditions and without requiring any special device by heating an aqueous suspension of powdery CaHPO4 .2H2 O having platelike crystal form and fine powder CaCO3 to a specified temp. and maintaining the suspension at this temp. SOLUTION: The objective crystal is produced by heating an aqueous suspension of powdery CaHPO4 .2H2 O having platelike crystal form and fine powder CaCO3 having a <=5μm average particle size to a temp. within the range of 40 to 70 deg.C and maintaining the suspension at this temp. to allow it to react. At this time, when this temp. is <40 deg.C, the reaction rate becomes slow and unreacted powdery CaHPO4 .2H2 O or CaCO3 remains in the reaction product even at the time of allowing the suspension to react for >=10hr. On the other hand, when this temp. is >70 deg.C, crystal disintegration due to the release of crystallization water from CaHPO4 .2H2 O occurs to incur the formation of hydroxyapatite crystallites.

IPC: H01L27/148
Filed: 1983-10-17
Abstract: PURPOSE:To eliminate both reflection in the interface of an insulating layer and absorption in the same layer obtaining a CCD photosensor with high sensitivity by means of selective-etching the first and the second insulating layers on the upper part of light receiving surface of photodiodes. CONSTITUTION:A protecting film 7, the second and the first insulating layers 6, 5 and oxide thick films 3 are formed on the region excluding a light receiving surface 8 of photodiodes 2 while a light shielding Al layer 10 is provided by means of insulating each gate from an insulating layer 5 and further insulating from an Al wiring layer 9 and another insulating layer 6. After forming the Al layer 10, the insulating layers 5 and 6 are simultaneously removed through masking and etching processes to be covered with the protecting film 7. At this time, the light utilization may be improved together with the sensitivity since the reflection and absorption of light on the upper part of the light receiving surface 8 of the photodiodes 2 may be performed only by the protecting film 7 and the oxide thin films 4 eliminating the reflection and absorption of the insulating layers 5 and 6.

Filed: 1982-11-02
Abstract: PURPOSE:To generate helium ions depressed with kick phenomena, which are uniform without being mixed with impure ions, by a method wherein helium ions are implanted by making the gas composed of helium gas mixed with argon gas as raw gas. CONSTITUTION:Raw gas is made from helium gas mixed with argon gas. The mixing ratio is not specifically limited. When helium ions are implanted by using this raw gas, the kick phenomenon is depressed. For example, when the implantation of helium ion is carried out by using helium gas only, the kick phenomena are generally generated min, 1,000 times per 1hr. However, when mixed with argon gas, the number of kick phenomena becomes max, 100 times per 1hr though the number of mixing ratio of argon may be large or small.
