Title: Information recording apparatus
Inventor: OKANO HIDEO
IPC: G06F12/08
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording apparatus whose transfer efficiency is enhanced by a method wherein, when data is written into a storage means by every definite amount, it is written via another storage means when the data write time exceeds a maximum value. SOLUTION: Received data in an optical shape is input to a reception circuit 6A via a pin diode 14, it is sent to a main control part 6B when one byte portion is accumulated, it is converted by a parallel conversion part 60, and it is transferred to a buffer memory 6C as one-byte data. Then, when data covering one block is accumulated in the memory 6C, a write operation to a temporary recording medium part 100a is started. When the data is transferred to the medium part 100a, the main control part 6B outputs a write signal so as to record the data into a main recording medium 100b. It takes a definite time to write the data into the medium part 100b. However, when a data reception operation and a write operation to a semiconductor memory part 10 are performed simultaneously, the write operation can be performed efficiently.

Title: Boiling cooler
Inventor: NAGAKABE HIROYUKI
IPC: H05K7/20
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To enhance circulation of refrigerant by suppressing liquefaction of boiling refrigerant and vaporization of condensate in a connecting pipe with no restriction on the arrangement thereof. SOLUTION: A connecting pipe comprises a vapor introduction pipe 5 for introducing refrigerant boiled by a boiling unit into a condenser, and a liquid introduction pipe 6 for introducing condensate from the condenser to the boiling unit wherein an outer pipe 5a, 6a and an inner pipe 5b, 6b are combined concentrically in double pipe structure. Refrigerant flowing between the outer pipe 5a, 6a and the inner pipe 5b, 6b is susceptible to the outer atmosphere but refrigerant flowing on the inside of the inner pipe 5b, 6b is insusceptible to the outer atmosphere. Consequently, condensation of the boiling refrigerant flowing on the inside of the inner pipe 5b is retarded even if the vapor introduction pipe 5 is cooled by the air supply from an outdoor fan.  Similarly, boiling of the condensate flowing on the inside of the inner pipe 6b is retarded even if the liquid introduction pipe 6 is heated by the air supply from an indoor fan.

Title: Disk driver and display method
Inventor: USUI HIROYUKI
IPC: H04N5/781
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce the time when a succeeding menu is displayed by detecting an address and a size of data on a disk from a read request of data and analyzing them so as to set a moving target position of each head thereby moving each head to each target position. SOLUTION: Before displaying a menu on a display device of a computer 100, number of choices that is to be displayed on the menu is detected. Heads 1a-1c are moved to positions of data of a succeeding menu on a disk with respect to the detected number of the choices. Whether or not all the heads 1a-1c are moved is confirmed. When number of the heads is more than the number of the choices, the number of the heads equal to the number of the choices is moved. When number of the heads is less than the number of the choices, all the heads are moved. The menu is displayed on the display device of the computer 100 and the data are revised into an expression so that the choices corresponding to the moved heads are momentarily are displayed on the menu. Having moved each head in advance can reduce the time until the succeeding menu is displayed.

Title: Photoelectric conversion circuit
Inventor: TAGUCHI HISASHI
IPC: H03F3/08
Filed: 1992-11-27
Abstract: PURPOSE:To enhance the response speed of the photoelectric conversion circuit. CONSTITUTION:An emitter follower circuit 12 is provided in a pre-stage of an output circuit 17 and a photo diode 13 is connected between a base and an emitter of a transistor(TR) 11. Since the voltage gain AV of the emitter follower circuit 12 is the unity, the input side capacitance is equal to a base- collector capacitance C0b of the TR 11, that is, negligibly small. Although a voltage gain Av of the output circuit 17 is high, the output impedance of the emitter follower circuit 12 of the pre-stage is very low, then the base- collector capacitance C0b of the TR 11 is almost negligible. Thus, the adverse effect due to the Mirror effect in TRs 11, 15 is suppressed.
