Title: Optical disk device
Inventor: TSUNODA YOSHITO
IPC: G11B20/12
Filed: 1989-05-12
Abstract: PURPOSE:To stably record digital information large in capacity by replacing a clock frequency (f) by (1/2<n>)X(f) as moving a recording position on an optical disk according to the 1/2<n> of the radius of the outermost peripheral track. CONSTITUTION:A capacity C in the case of recording information on the disk with the radius (r) of the track at an outermost side with a constant frequency (f) has prescribed relation with a recording hole diameter (a) of one bit, track pitch P, and the radius (r1) of the innermost peripheral track, and the capacity C goes to the maximum value when it is r1=r/2. The number of pulses sent from an encoder 4 is selected so that all the address counters 5 are set at '1's i.e. 2<n> bits when a moving carriage 3 is moved by distance (r) along the radius of the optical disk 1. A position where the carriage 3 is located at the position of the outermost peripheral track is set as the address 0 of the address counter 5. When the carriage 3 is moved to an inner periphery by r/2, the output Qn of n-th bit of the counter 5 is inverted. A clock switching circuit 6 takes the AND of the Qn and the inverted Qn-1, and takes the AND and the frequency fn/2 of a clock circuit 7, then, they are inputted to an optical head 3a.

Abstract: PURPOSE:To improve the reliability of a sample by providing a constant temperature device which holds the inside of a sample chamber at both high and low limit temperatures, and applying a DC voltage when the temperatures in the sample chamber is both limit temperatures and measuring characteristics. CONSTITUTION:The high-temperature chamber 1-2 and low-temperature chamber 1-3 of a thermal shock testing instrument 1 are held at the specific temperatures previously. When a damper 1-6 between a sample chamber and the low- temperature chamber 1-3 is opened, the temperature in the sample chamber 1-1 drops abruptly and when the damper 1-6 is closed and a damper 1-5 is opened, the temperature rises abruptly. A sequence controller 5 inputs a signal synchronizing with the operations of the dampers 1-6 and 1-5 to a CPU 2-1 to drive a DC power source 3 and a data gathering device 4. Then measurement is taken in the limit temperature range of the sample chamber 1-1. The data processing of a data processor 2, on the other hand, is performed in the stop period of measurement. Thus, characteristics of a sample at the time of abrupt variation in temperature are grasped to improve the reliability of the sample.

Title: Manufacturing of heating chamber of microwave oven
Inventor: SHIMAMOTO KEIJI
IPC: F24C7/02
Filed: 1984-06-06
Abstract: PURPOSE:To form a painting line into a small size and to raise the lot number by carrying out painting on parts to be caulked by masking the parts prior to assembling components of a heating chamber, and then caulking and fixing the parts. CONSTITUTION:Masking A is applied to parts to be caulked of components of a front plate 2, a bottom plate 3, a ceiling plate 4 and a rear plate, and thereafter a resin paint 7 is applied to necessary surfaces. Then, the masking A at the caulked parts is removed and parts are mutually caulked and fixed. Thus, since the paint 7 does not adhere to the caulked part, the earth potential in the entire part of the heating chamber after the assembly is secured, wave leak from the junction is prevented. Further, the painting line is formed in a small size and the lot number is increased, and hence it is possible to decrease the cost.

Title: Voice recorder-regenerator
Inventor: ONISHI TADASHI
IPC: G10L19/00
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To avoid a problem of suddenly becoming unrecordable by detecting storable empty capacity of a semiconductor storage device, calculating recordable time from storable empty storage capacity, and displaying recordable time. SOLUTION: An already recorded pre-storage area 1001 and a still unrecorded recordable empty storage area 1002 exist in a storage circuit 100. A recordable time calculating function 118 existing in a control part 101 detects empty storage capacity by recognizing this empty storage area 1001 by an empty storage capacity detecting function 202 in recording operation. Recordable time 200 is also obtained by subtracting the empty storage capacity at a preset bit rate by a subtracting function 201. The recordable time 200 is delivered to a display control function 203 to control a display part 103, and is displayed. Therefore, since a user can seize an unstorable condition of a semiconductor storage device before becoming impossible, a problem of suddenly becoming unrecordable can be avoided.
