Title: Adjusting method of control circuit for optical disk drive device
Inventor: TAKAMURE HISANORI
IPC: G11B7/09
Filed: 1995-04-18
Abstract: PURPOSE: To provide a method for adjusting a control circuit for optical disk drive which can improve the S/N ratio of track signals while maintaining a required jitter level. CONSTITUTION: A laser module 1 is provided with a semiconductor laser 3, a microprism 4, a front photoreceptor element 5, a rear photoreceptor element and an amplifier 9, and an amplifier unit 10 which outputs RF signals and track error signals is also installed. Defocus adjustment is applied to the maximum point of the amplitude of RF signals by changing the injection amount of electric offset to focus error signals while monitoring the amplitude of the RF signals. Next, in the condition that track servo is once made off and focus servo alone is made on, an optical disk 8 is rotated to output a track traverse signal and to adjust defocus in the direction of increasing this track traverse signal. The amount of defocus is set at, e.g. 0.3μm to l.0μm.

Title: System control method applying error tracing
Inventor: USHIJIMA MASATO
IPC: G06F11/34
Filed: 1994-04-28
Abstract: PURPOSE:To accurately and easily decide an error occurrence place based on the stored trace information, i.e., the attribute information on the state change of a program. CONSTITUTION:A trace processing hardware 22 functions to collect the attribute information on the state change of programs and stores these collected information in a tracing buffer 24 when the trace processing is started by a user program 21a or a system program 21b. In a system control method which applies the error tracing, the process attribute information is stored in a tracing buffer memory or a tracing buffer area of the memory when the state change of the program occurs. When an error is detected, the attribute information stored in the buffer memory or the buffer area is traced. Then an error deciding program decides the program of the error occurrence place.

Title: Cooling-heating equipment
Inventor: ISHIYAMA HIROAKI
IPC: F25B13/00
Filed: 1993-04-20
Abstract: PURPOSE:To prevent frosting in an evaporator at the time of heating and to prevent formation of dew in the vicinity of the evaporator at the time of cooling by reducing a rise in the temperature of a refrigerant in a process of evaporation by providing a pressure reducing means for the refrigerant flowing through the evaporator in cooling-heating equipment wherein a non-azeotropic mixture refrigerant is used as a working refrigerant. CONSTITUTION:A pipe 1 is a refrigerant passage and a fin 2 is provided in the circumference of the pipe 1. In the vicinity of an inlet of an evaporator, a refrigerant branches and flows along two passages, joins and flows along a single passage in the middle and reaches an outlet of the evaporator. When a non-azeotropic mixture refrigerant flows through the evaporator, it branches and flows along the two passages at first and, therefore, the flow rate of the refrigerant in each passage becomes small, a pressure loss becoming small as well and the temperature of the refrigerant rising as evaporation proceeds. When the refrigerant comes soon to a joining point, the refrigerant having passed through the different passages joins together and begins to flow through the single passage and the flow rate of the refrigerant increases. As the refrigerant approaches the outlet of the evaporator, the pressure lowers and the rise in the temperature of the refrigerant lessens.

Title: Image reader and facsimile equipment
Inventor: HORI TAKESHI
IPC: H04N1/38
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of shadows on the receiving side and the extension of processing time due to the increment of image data amount. SOLUTION: While sending a transmitting original by a reading roller 12, a line sensor 11 arranged in the direction orthogonal to the sending direction of the original is allowed to wait only for the timing of a margin at the start and end of an image data sending period at the time of scanning the original in its width direction and generating and outputting the image data. Thereby since the margin is not included in the entering timing of an image data compression part 15, shadows generated on both the ends of paper are not outputted, even at the time of using a regular line sensor 11, transmission data are reduced and the quantity of processing is reduced.

Title: Heat exchanger for instantaneous water heater with hot water storage part
Inventor: NISHI TAKAHIRO
IPC: F24H1/14
Filed: 1989-04-13
Abstract: PURPOSE:To improve a hot water outputting characteristic by a method wherein an upper layer pipe is made to have a larger diameter than that of a lower layer water pipe. CONSTITUTION:A heat exchanger 1 for an instantaneous hot water boiler is made such that water pipes are arranged in upper and lower multilayers and at the same time an upper layer water pipe 2A is made to have a larger diameter than that of a lower layer water pipe 2B, in which the large diameter part is formed at a hot water storing part 3. The upper layer water pipe 2A has a hot water storing part 3 having a large capacity, resulting in that a plug 8 of a hot water feeding port 7 is closed and a feeding of hot water is stopped temporarily and even if the hot water is fed out again, cold water may not be formed instantaneously. Even in case that the hot water within the hot water storing part 3 is not fed out, a part of a gas burner 9 is correspondingly interlocked with a temperature of hot water and ignited, or if the temperature of hot water is kept at a constant temperature by a heating source other than the gas burner 9, water having an appropriate temperature within the hot water storing part 3 is at first fed out even if the hot water is fed out any time, resulting in that it is possible to prevent cold water from being immediately fed out. Simultaneously with the feeding-out of the hot water, water within the lower layer water pipe 2B is heated under combustion in the gas burner 9, resulting in that the heated water is mixed with another hot water in the hot water storing part 3 and fed out. It is not necessary for waiting for a long period of time until hot water of applied temperature comes out of the pipe and the it is possible to realize a feeding of hot water in a fast rising.
