Title: Manufacture of lead frame
Inventor: SAIGO MASAKATSU
IPC: H01L23/50
Filed: 1989-03-16
Abstract: PURPOSE:To enable the micronization of an inner lead by a method wherein the upper face of a lead section is formed into a prescribed size through a first etching, which is coated with an etching resistant material and then subjected to a second etching. CONSTITUTION:Prescribed resist patterns 2a and 2b are formed on the upper and the lower face of a lead frame metal plate 1 respectively, which is subjected to a first etching of half etching to form grooves 4a and 4b. Then, an etching resistant material 5 is applied onto only the upper face of the metal plate 1, which is subjected to a second etching. In this etching, only the lower face of the metal plate 1 is etched to make the groove 4b large enough until the etching resistant material 5 of the groove 4a is exposed. Then, the material 5 and the resists 2a and 2b are removed through a solvent to form a required lead frame 6. By this setup, the micronization of an inner lead can be promoted.

Title: Base material for image forming material
Inventor: MORITA YUICHI
IPC: B41M5/52
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To increase glossiness at a glance, provide both an image forming material and a print thereof without irregular glossiness, and maintain good releasability from a cooling roll at the time of manufacturing a base material by applying a multilayer structure to a resin layer and base paper for forming an image thereon. SOLUTION: Regarding a base material for a resin coated paper type image forming material having at least one side of base paper coated with resin capable of forming a film, the base material for the image forming material is made to have a multilayer structure for the resin layer and the base paper where an image is formed. A method for applying the multilayer structure to the base paper may be selected from a method for using a multilayer head box, a method for feeding upper layer pulp slurry sequentially to lower layer pulp slurry at a dehydrating process on a wire, and a method for combining each layer of independent sheet type by use of the Fortlinear paper machine or the cylinder mold. The resin layer and the base paper, however, should preferably be made to have a multilayer structure at the early stage of a paper making process, in view of interlayer bonding strength.

IPC: B60B25/02
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To avoid the labor of assembling a coupled wheel. SOLUTION: In a peripheral wall of a cylindrical part 1 of each wheel piece 10, a projection 3 and a recess 4 are provided which are mutually fitted by insertion in the axial direction, and on an end and a bottom of the projection 3 and the recess 4, a projecting portion 13 along the peripheral direction and a recess portion 14 to be fitted into the projecting portion 13 are respectively formed in a continuous manner. Surfaces which are opposite in the axial direction of the projecting portion 13 and the recess portion 14 are tilt surfaces 13' and 14', respectively.  Coupling of the wheel pieces 10 is accomplished by: inserting the projection 3 of the axial direction into the recess 4; bringing the projecting portion 13 to the position where it fits into the recess portion 14; rotating the wheel pieces 10 in the peripheral direction in relation to each other, thereby engaging the projecting portion 13 with the recess portion 14 of the peripheral direction; and then injecting air into a tube to cause a bead portion to disengage rims 2, 2 of the wheel pieces 10, 10. As a result, the tilt surface 13' of the projecting portion 13 and the tilt surface 14' of the recess portion 14 are engaged in the axial direction and rotation in the peripheral direction of the wheel pieces 10, 10 is prevented. The pair of wheel pieces 10 can thus be coupled without using a bolt.

Title: Control circuit of air conditioner
Inventor: MASUDA SHINTAROU
IPC: F24F11/76
Filed: 1982-04-21
Abstract: PURPOSE:To suppress the blow-off of cool air during the room heating operation by monitoring the blow-off temperature of the air conditioner, and controlling the rotational speed of a blower. CONSTITUTION:A minus terminal input voltage V- of a comparator 3b which drives a control relay 6b through a transistor 5b changes according to the suction temperature of a thermistor 1. On the other hand, a plus terminal input voltage V+ changes according to a thermistor 2 which detects the blow-off temperature. The comparator 3b operates so that the output becomes zero potential when the minus input voltage is higher than the plus terminal input voltage, and the base current of the transistor 5b does not blow and the control relay 6b does not operate. On the otherhand, when the comparator 5b operates in a manner reverse to the above described manner, the control relay 6b is operated. Since each of the thermistors 1 and 2 has a property of decreasing the resistance value when the temperature of said thermistors increases, the input voltages V+ and V- of the comparator 5b increase substantially rectilinearly with respect to the temperatures. Accordingly, the transistor 5b, that is, the drive relay 6b is turned ON or OFF depending upon whether the difference between the blow-off temperature and the suction temperature is large or small.

Title: Signal generating circuit
Inventor: OOSAKI MASASHIGE
IPC: G06F1/04
Filed: 1982-04-21
Abstract: PURPOSE:To vary not only the period, but also the duty ratio of a control signal, by providing one counter with two registers and two comparing circuits, and varying the set values of the two registers. CONSTITUTION:Once the contents of a counter 3 coincide with the set value A of a register 4a, a comparing circuit 5a outputs a coincidence signal Pa. When this signal Pa is outputted, an R-SFF6 is set. Then, the output Q of the FF6 varies from a low to a high level and its output -Q1, i.e. the control signal Pc varies from the high to the low level. Further, when the output Q of the FF6 varies to the high level, the circuit 5a is placed in an inhibited state through an AND gate 9 and a comparing circuit 5b is released from being inhibited to reset the counter 3. When the counted value of the counter 3 coincides with the set value B of a register 4b, the comparing circuit 5b outputs a coincidence signal Pb and while the output Q of the FF6 varies to the low level, the -Q varies to the high level. Said operation is repeated to obtain outputs correspondig to the values A and B.

Title: Communication controller
Inventor: NAKAMURA KOICHI
IPC: H04L29/02
Filed: 1990-03-14
Abstract: PURPOSE:To reduce wait time for interruption processing by using plural processors so as to control data transfer in a communication controller provided with a serial/parallel(S/P) data conversion section to each line and selecting a processor not processing an interruption. CONSTITUTION:When an interruption request is received via a signal line 31 while S/P data conversion sections 8-10 connecting respectively to relevant lines 50-52 are in reception state, an interruption control section 1 discriminates a processor 2 or 3 not in the processing state based on a display output representing whether or not the relevant processors 2, 3 are in processing from processing state latch sections 4, 5 and applies interruption transfer of a reception data to the buffer memory 7 from the conversion sections 8-10. Thus, it is not required to apply interruption processing after the processing is finished like the use of a single CPU, the wait time for the interruption processing is reduced thereby enhancing the line control processing performance. Moreover, the similar processing is applied also to the case of transmission.

Title: Outer surface grinding method for columnar material and outer surface grinding device

IPC: B24B29/04
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To grind an outer surface uniformly across an entire length, even at a columnar material with somewhat different outer diameter. SOLUTION: A columnar material P which is a material to be ground is sent into the inside of a grinding tool 3 mounted in the inner periphery side of a grind ring 1 through an elastic body 2 and the grid ring 1 is moved along the orthogonally crossing direction with the pipe axis of the columnar material P so that the inner periphery surface of the grinding tool 3 is push-pressed to the outer periphery surface of the columnar material P and the grinding tool 3 is rotated. The outer surface of columnar material P can be ground while moving the grind ring 1 to the long axis direction of the columnar material P.  Thereby, as the grinding tool 3 is push-pressed to the columnar material P through the elastic body 2, even if other bending and deformation exists, the grinding tool 3 is followed to the outer surface of the columnar material P and the outer surface of the columnar material P can be ground uniformly.
