Title: Etching device
Inventor: KASAI YOSHIHARU
IPC: C23F1/08
Filed: 1990-06-15
Abstract: PURPOSE:To keep the etching capacity constant at the time of bringing a liq. etchant into contact with a material to be etched by means of spraying, etc., by dipping a metallic electrode of the same kind as the material and a reference electrode in the etchant to measure the potential difference between both electrodes and the deterioration degree of the etchant, and adding the regenerant in accordance with the deterioration degree. CONSTITUTION:A metallic electrode 2 of the same kind as a material to be etched is dipped in a liq. etchant 1, and an insoluble metal is used for a reference electrode 3. When the electrodes 2 and 3 are dipped in the etchant, the metallic electrode 3 is dissolved at a rate corresponding to the capacity of the etchant. At this time, the capacity of the etchant is expressed by the voltage produced in an ORP meter V, and the deterioration degree of the etchant is measured in this way. The voltage of a power source E is preferably adjusted at this time to conduct an extremely weak current, and the current value is freely set while measuring the current with an ammeter A.

Title: Ic socket and inspection jig
Inventor: ENATSU HIROKI
IPC: G01R31/26
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce contact failure between an outer terminal of an IC and the contact surface of a connecting terminal of an IC socket and conduct to stable measurement even if foreign matters are attached to the back surface of the outer terminal of the IC by forming the contact surface of the connection terminal so as to come in contact with the back surface of the outer terminal at points. SOLUTION: Many projections 11 are formed on at least contact surface 10 of a connecting terminal 9 to an outer terminal of an IC. By forming the contact surface 10 so that many projections 11 exist, when the IC is fit to an IC socket, the back surface of the outer terminal of the IC comes in contact with the contact surface 10 at points. Even if foreign matters such as solder chips are attached to the back surface of a lead of the IC, the point contact state is kept, and contact failure between the back surface of the lead and the contact surface 10 of the connection terminal 9 can be reduced. By fixing the IC socket to an inspection jig, measurement of electric characteristics is made stable and accurate.

In the manufacture of such magnetic core 13, photoresist R1 is coated on a thin film of a magnetic material 14a formed on substrate P along with the patterning applied. After this, film 14a is etched into the taper form via the chemical etching solution. Then resist R1 is removed, and nonmagnetic layer 20 having the film thickness equal to the fixed gap measurement is formed. Furthermore, magnetic film 15a is formed on layer 20. Then photoresist R2 is coated with the patterning applied, and then the taper etching is given to film 15a to remove R2. Thus a thin film magnetic core with gap 16 formed between layers 14 and 15 is obtained.

Title: Reproducer of optical disk record
Inventor: TAKAMORI HIROMITSU
IPC: G11B17/04
Filed: 1983-08-31
Abstract: PURPOSE:To load assuredly an optical disk with simple constitution even in case the disk is loaded erroneously by providig a guide sloping part and a position control part for the disk at a disk store part of a tray, and also a disk position control part at the tray inlet/outlet of a cabinet respectively. CONSTITUTION:An optical disk 25 is loaded to the disk store part 16 of a tray main body 13 with the disk stuch out toward the end of the part 16, and an ejection key 14 is operated. In such a case, the fringe part of the disk 25 touches the end of opening part 22 of a front panel 12, and a control part 21 and is therefore shifted toward an arrow C as the disk is loaded toward an arrow B. When the disk 25 is loaded more toward B, the fringe part of the disk is detached from the edge of the part 22 and abuts on a projection part 24 for control of disk position at the right side to receive the position control. Thus the disk 25 is shifted toward C when it is loaded further. When the disk is shifted toward C until its maximum diameter part abuts on the part 24, the disk is guided by a sloping part 20 of the part 16 to receive the position correction to the part 16. Thus the disk 25 is loaded correctly to the part 16.

Title: Controller for mixing hot and cold water
Inventor: EGAMI TOYOHIKO
IPC: G05D23/13
Filed: 1987-06-25
Abstract: PURPOSE:To improve the stability of control by a method wherein a reference deviation value is set in response to a set hot water temp. set by a set device for the hot water temp. and when a temp. deviation is equal to the reference value or less, the computation of the amount of energization is changed from a primary set part for the amount of energization to a secondary set part for the amount of energization. CONSTITUTION:When preset hot water temp. is in the region of 45-50 deg.C, the amount of energization is set by a primary set part 19 for the amount of energization until the temp. of mixed hot water approaches the temp. fairly near the preset temp. (the preset temp. TS+ or -C) deg.C and control sensitivity is susceptible and the mixed hot water temp. can be brought close to the preset hot water temp. in a short time. When the preset hot water temp. is in the region of 60 deg.C or more, the amount of energization is set by a secondary set part 20 for the amount of energization, if the mixed hot water temp. is rather separated from the preset hot water temp. and brought to (TS+ or -a) deg.C, and the control sensitivity is switched to be lower and the control sensitivity in a region where the control effect appears largely is therefore made lower and the generation of hunting does not take place easily and the stability of the control is therefore improved.

Abstract: PURPOSE:To make a curvature radius constant, with regard to the detection of the vehicle speed by using a light signal, by fixing a part of an optical fiber cable by a cable supporting tool having a curved part, suppressing the vibration of the optical fiber cable, and bending the cable along the curved part. CONSTITUTION:Two pieces of the optical fiber cables are enclosed in a cover 2. The coating and the reinforcing material of the front end is cut away, and a plug 17 is fixed. The longer cable is curved at a large radius along the inner surface of the cover from the front side of the encoder 13 and supported by the cable supporting tool 25. When the vehicle speed sensor is attached to an automobile, the encoder 13 is rotated at a speed proportional to the wheel rotation of the automobile. The light emitting element of the optical fiber cables 16 and 16 continuously emits the light at a constant intensity. The light through the encoder 13 is detected by the light receiving element at the other end. Since many cutouts 24,... are provided at the periphery of the encoder 13, pulse light is detected by the light receiving element, and the vehicle speed can be detected.
