Title: Image forming device
Inventor: NAKAJIMA YOSHIHIRO
IPC: G03G15/02
Filed: 1991-05-15
Abstract: PURPOSE:To restrain the evolution of gas such as ozone, to prevent the deterioration in the characteristic of a high gamma type photosensitive body and to obtain a high-resolution image by digital light input by using only positive corona discharge for electrostatic charging and transfer. CONSTITUTION:In a printer using an electrophotographic process, a latent image carrier 1 is obtained by forming a photoconductive photosensitive layer 3 using the high gamma type photosensitive body on a conductive supporting part 2. The photosensitive layer 3 is electrostatically charged to be positive by using a positive electrostatic charging corona charger 4 and is irradiated photo from a light source 5 in accordance with an image so that an electrostatic latent image may be formed on the layer 3. Toner 8 electrostatically charged to be negative is stuck to the layer 3 to develop the electrostatic latent image by a developing device 21. Furthermore, the positive corona discharge is impressed to transfer a toner image on a recording paper 16 by a corona transfer device 15. Since the toner 8 electrostatically charged to be negative is used and the positive electrostatic charge having a reverse polarity to against to the toner 8 is applied to the photosensitive body by the corona charger 4, the evolution of the gas such as ozone or nitrogen oxides is reduced.

Title: Insert mold molding method
Inventor: WATANABE MASASHI
IPC: B29C33/12
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To satisfy a relative height precision of a protrusion and a molding member, even when the heights of parts with the protrusion to be molded are not uniform by compressing a projecting part to the specified thickness with the help of the member coming into contact with the tip of the projecting part of a platelike member of a cavity side part of a mold and a part coming into contact with the back face of the projecting part of the other side part of the mold. SOLUTION: A core pin A10c coming into contact with the tip of a center pole 1a of a yoke 1 during insert-molding, is provided in an insert 10a of a bottom force 10, and the back of the center pole 1a is firmly supported by a core pin B11b with a sufficient inner diameter of a top force 11. Both core pin A10c and core pin B11b are highly rigid from a viewpoint of mold structure, so that the center pole 1a of a comparatively pliable material is compressed to a specified size in the process of insert molding. Thus it is possible to precisely set the value of a void (g) in the same mold interior at an expected void value g0 and thereby easily set the dispersion of the void value (g) of a finished product within the tolerable range. Consequently, the mutual size between the protrusion and the resin-molded part can be precisely set as specified.

Title: Ventilator for vehicle
Inventor: OSHIRODA AKAAKI
IPC: B61D27/00
Filed: 1980-08-13
Abstract: PURPOSE:To conduct fresh air into a vehicle or discharge contaminated air out of it, by installing a multiblade fan at the open part of the vehicle and driving the fan with a reversible electric motor. CONSTITUTION:When a multiblade fan 17 is turned in the direction of an arrow by the forward rotation of an electric motor 21, external air introduced through an open part 14 is conducted into a vehicle chamber 16 through a hole 15 as shown by streamlines. A constant quantity of fresh air is thus supplied into the vehicle chamber 16 regardless of the running and stoppage of a bus. When it is raining, rain water is blocked by a stop plate 19 and only the external air enters into an outer frame 13 through openings 20 between a fan guide 18 and the stop plate 19. Therefore, the rain water cannot enter into the vehicle chamber 16 through the hole 15. Since the rotary blades of the fan 17 are placed in face of almost all the open part 14 of the frame 13, effective ventilation is caused through the open part 14.

Title: Method and device for treating substrate
Inventor: IMANISHI YASUO
IPC: H01L21/02
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To improve the product yield of a substrate by making the treatment hystereses of a plurality of substrates in the same lot equal to each other so that the treatment quality may be managed easily by incorporating a plurality of identical substrate treating sections which perform the same treatment on a substrate transporting means under the same treating condition in a plurality of substrate treating sections. SOLUTION: In a substrate treating device, the actual substrate treating time of a substrate treating section, particularly, a heating section 16 becomes the sum of the waiting time of a substrate thrown in the section 16 for waiting the start of heating at an upper distant position and the actual heating time of the substrate at a lower heating position. Therefore, the substrate treating time of the substrate treating device becomes constant regardless of the treating route of the device, because the actual substrate treating time of the heating section 16 determines the rate of a treatment flow. In this case, the substrate treating time of the substrate treating section, namely, the heating section 16, other than a plurality of identical substrate treating sections which perform the same treatment under the same treatment condition, namely, coating sections 12 and 14 is managed.

Title: Combustor of gas turbine
Inventor: SUYARI MAMORU
IPC: F23R3/30
Filed: 1983-06-18
Abstract: PURPOSE:To finely atomize and homogeneously blend the fuel for combustion for thereby lowering NOx emissions, by providing a primary air feeding swirler at the inlet of premixing channel in front of a combustion chamber and providing the front face of swirler with a fuel feeding pipe having its injection ports faced to respective blades of swirler. CONSTITUTION:A primary air A is caused a swirling movement by means of blade 16 in passing through a swirler 15. A liquid fuel is injected in an atomized state through fuel injection ports 18 defined in a fuel feeding pipe 17 arranged in front of a swirler 15. The fuel is then finely atomized in contact with a high- speed air stream passing through blades 16, an collides with blades 16 for further atomizing. Since the number of fuel injection ports 18 is equal to that of blades 16, the fuel is uniformly injected over the entire air stream which passes through the swirler 15, and can be thus homogeneously blended. The fuel is thus finely atomized and homogeneously blended at the inlet of premixing channel 10 and therefore can be evaporated and homogeneously blended inside the premixing channel in an extremely short period. In consequence, NOx emissions can be lowered.

Title: Switching position correction circuit
Inventor: TAKEUCHI YUKIO
IPC: G11B15/14
Filed: 1985-05-24
Abstract: PURPOSE:To prevent pitching of a screen and the exposure of a switching horizontal line under the screen at variable speed reproduction by detecting the phase difference between a switching pulse and a reproduction vertical synchronizing signal and correcting the switching delay quantity when the phase is not within a prescribed width. CONSTITUTION:An output of a tag pulse detection circuit 9 is inputted to a FF 12 via a MM 11 and a switching pulse 8 of the output is fed to a correction circuit A1. The pulse 8 is delayed by 5H by a MM 15 and given to a latch circuit 18, MMs 16, 17 form an 'H' signal 25, which is given to a latch circuit 19 between 8H-10-odd H. When an output of the circuit 18 goes to H while a reproduced vertical synchronizing signal 20 is between the switching point and 0-5H, the delay of the MM 11 is decreased and when an output of the circuit 19 goes to H while the signal 20 is between the switching point and >=8H, the delay of the MM 11 is increased. As a result, the phase of the signal 20 to the pulse 8 is corrected within 5H-8H. Similar control is applied in a correction circuit A2.

IPC: H01L21/74
Filed: 1979-08-29
Abstract: PURPOSE:To prevent the autodoping to an epitaxial layer to be made to grow on a layer when double buried layers are to be formed on a semiconductor substrate by forming a buried layer reversely conductive against the substrate and a buried layer identically conductive with the substrate by a method wherein at least the upper side buried layer is formed by ion implantation. CONSTITUTION:An N type buried region is formed by diffusion in the surface layer of a P type semiconductor substrate, and after the forced oxidation is performed, a P type buried region is formed in lamination on it by photo resist process. At this time, the formation of the P type buried region constituting the upper layer is performed by the P type impurity ion implantation, and then buried region is formed by burying and diffusion. By this way, although an N type epitaxial layer is made to grow on the whole face of the substrate containing these regions, the autodoping phenomenon does not take place in the epitaxial layer, and the precision of layer resistance of the P type buried region is improved.

Title: Josephson latch circuit
Inventor: OOHORI TATSUYA
IPC: H01L39/22
Filed: 1984-05-31
Abstract: PURPOSE:To hold data in a superconduction loop securely by lowering an enable signal for a latch first and then lowering a bias current when data is latched by an interference element. CONSTITUTION:Current delay operation is utilized for the bias current and enable signal inputted to the interference signal 6 to set the value of a resistance 12 where the bias current flows to a value large enough to have a load line shown by (a) and the value of a resistance 16 where the enable current flows to a value small enough to have a load line shown by (b), delaying the falling of the bias current behind the falling of the enable signal. Therefore, the enable signal falls first and then the bias current falls, so that a circulating current is held in the superconduction closed loop 7 securely without malfunction. Thus, the resistances 12 and 16 are set to the high and low resistance values respectively to vary the timing of the bias current and enable signal, thereby preventing malfunction which occurs when the bias current and enable signal fall at the same time.
