Title: Title input device for recording medium
Inventor: SATO MAKOTO
IPC: G11B27/11
Filed: 1997-07-06
Abstract: PROBLEM TO BE SOLVED: To facilitate input of a title. SOLUTION: When a take-in key of a tuner unit 1 is pressed, received character information of a FM character multiplex broadcasting receiving tuner 3 is stored in a buffer region 5 for take-in of a memory 5. When a disk title of MD(mini-disk)-MO(magnet-optical)11 is required to be inputted, a mode is turned to a title input mode, and after selecting a disk as an input object unit and by pressing a calling key and an ENTER key, a first system controller 7 stores received character information previously taken in a title input operation region 5C of a memory 5 corresponding to a disk being an input object unit.  After this, when the ENTER key and a title key are pressed, the first system controller 7 sends contents of the title input operation region 5C to a MD recorder unit 10, and a second system controller 17 records it in an UTOC (user's table of contents) of the MD-MO11 before ejection.

Title: Substrate-carrying equipment of electronic component- mounting machine
Inventor: KOYAMA TOSHIYUKI
IPC: H05K13/02
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To judge whether a substrate is being carried appropriately or not and to prevent the substrate from being damaged and a motor from failing by providing a detection device for judging whether the substrate can be continuously carried or not when a trouble occurs while the substrate is being carried according to the current value of the motor for driving the transportation of the substrate. SOLUTION: The substrate-carrying device with a motor protection function monitors the failure in a motor 1 for driving the transportation of the substrate by combining the motor 1 and a motor driver 2. More specifically, a pulley 3 is rotated by driving the motor 1, and for example a detection device 2A incorporated into the motor drive 2 judges whether or not a lever 5 that is operated following a belt 4 has been carried appropriately from the state of the motor 1, while moving from a return limit sensor 6 to a going limit sensor 7 by the protection function of the motor 1. Either a current value, a torque, or a rotary speed is judged by the detection device 2A, thus judging whether the substrate is being carried appropriately or not while the substrate is being carried.

Title: Film thickness measuring method for magnetic garnet crystal film
Inventor: FUJII TAKASHI
IPC: G01N24/10
Filed: 1994-08-22
Abstract: PURPOSE: To easily and accurately measure the thickness of a magnetic garnet crystal film by finding difference between the value of magnetic field of a ferromagnetic resonance spectrum and the value of magnetic field of a Walker mode spectrum, using the resonance of electron spin resonance. CONSTITUTION: The value H1 of magnetic field of a ferromagnetic resonance spectrum A at a point (a) and the value H2 of magnetic field of a Walker mode spectrum B at a point (b) are calculated electron spin resonance (ESR) and, then, a relationship of t=1/α.Hd (a = proportion constant) is thereby found between the difference Hd of the values H1 and H2 , and the thickness (t) of a crystal film. Thereafter, the film thickness (t) of several types of samples having different film thickness is observed by use of a scanning type electron microscope through the application of the relationship, depending on the material composition of a sample or the size thereof. Then, the corresponding difference Hd due to ESR is obtained to determine the value of α.  As a result, the required thickness (t) of the crystal film can be subsequently measured simply by obtaining the difference Hd . Furthermore, the thickness (t) can be measured in nondestructive state without any need of cutting out the sample, depending on a crystal size and a process can be simplified.

Title: Electronic freezer
Inventor: YANAGIDA AKIRA
IPC: F25B25/00
Filed: 1988-08-07
Abstract: PURPOSE:To provide an electronic freezer not consuming useless electrical power by a method wherein in case that an operation of a compressor is stopped during operation of a freezing cycle, a control means is provided to control a turning-off of a thermoelectric element. CONSTITUTION:When a temperature of a refrigerator chamber 8 is lowered and a sensing temperature of a temperature sensor 10 is lower than a set temperature, an energization of a relay 12 is turned off under an instruction from a control circuit 20 so as to release an electromagnetic clutch 13. Due to this fact, an operation of a compressor 1 is stopped, and the cooling operation is stopped. Simultaneously, an energization of a thermoelectric element 5b is also turned off, so that an operation of an electronic freezing unit 5 is stopped and the freezing operation is also stopped. During operation of the freezing cycle, in case that the operation of the compressor 1 is stopped due to a temperature control, an evaporating temperature of coolant in a freezing evaporator 5a cooling a high temperature side of the thermoelectric element 5b is increased and the high temperature side is not sufficiently cooled, so that a temperature difference between a high temperature side and a low temperature side of the thermoelectric element 5b is increased. As the temperature difference at this end surface is increased, a freezing capability of the thermoelectric element 5b and an energy consumption efficiency are decreased. Accordingly, during this period, an energization of the thermoelectric element 5b has a poor efficiency and a turning-off of the energization causes a useless consumption of electrical power to be avoided.

IPC: F02M59/26
Filed: 1989-07-28
Abstract: PURPOSE:To prevent the generation of cavitation by forming the first lead which communicates to one throttle effluence port and the second lead which communicates to other intake/discharge port in delaying from the first lead, at the termination of the under-pressure process onto the outer periphery of a plunger for sending fuel into a plunger chamber, under pressure. CONSTITUTION:When a plunger 23 shifts to the termination time of the under- pressure sending process, the corresponding first lead 42 communicates to a fuel throttle effluence side port 29, and the fuel in a plunger chamber 24 is discharged outside a protector 38, and the pressure in the plunger chamber 24 lowers, and the under-pressure sending-out of fuel is completed. If the plunger 23 shifts by the dimension (x) immediately after this time, the second lead 34 communicates to a fuel intake/discharge side port 30, and fuel is discharged outside the protector 38 also from a lead 43 side. Therefore, the fuel in the plunger chamber 24 is discharged outside, lowering the pressure stepwise, and the spill energy is gradually reduced, and the generation of cavitation can be suppressed.
